<abstract>
<p>&#x201C;The prosperity of the population and son, the prosperity of the country&#x201D; means that the more family members and male offspring, the more stable and prosperous the family foundation of future generations. This concept is deeply engraved in China&#x2019;s traditional culture, and affects the behavior and decision-making of the actual controller as a parent. Chinese family enterprises are facing urgent problems such as power transfer and leader replacement. Although some studies have paid attention to the relationship between children&#x2019;s characteristics and enterprise inheritance, they have not connected this relationship with the internal mechanism of successor selection. The existing theoretical research lacks in-depth analysis of the influence mechanism of children&#x2019;s characteristics on professional manager appointment. Therefore, we attempt to make up for this deficiency. Based on this, we take Chinese family listed companies from 2009 to 2019 as a sample to test the impact of the number and the gender structure of actual controllers&#x2019; children on family enterprises&#x2019; professional management. The study found that the number of children, especially the number of sons, will inhibit the professional operation of enterprises. This conclusion is still true after the robustness test. Further research found that compared with daughters, sons have a more significant impact on professional management. At the same time, the greater the ownership proportion of the actual controller, the stronger the correlation between children&#x2019;s characteristics and professional management. We not only studied the influencing factors of enterprise succession from the perspective of children&#x2019;s characteristics, but also enriched the organization theory in the context of family business, which is helpful to promote the benign evolution and healthy and sustainable development of enterprises.</p>

<title>Introduction</title>
<p>The Chinese saying, &#x201C;the prosperity of the population and son, the prosperity of the country,&#x201D; is contained in Chinese traditional culture. The more the population of future generations, especially &#x201C;men,&#x201D; the more stable and prosperous the family foundation. This concept also affected the management of their own business by the ancient &#x201C;owners.&#x201D; Due to the inconvenience of communication and transportation, the &#x201C;owner&#x201D; cannot personally operate business in each region and has to hire the &#x201C;shopkeeper.&#x201D; However, in the era of imperfect laws, this management model is likely to have moral hazard problems. If the &#x201C;owner&#x201D; has more children, especially boys, the appointment of the &#x201C;shopkeeper&#x201D; can be reduced to ensure that the family business continues to prosper for generation to generation in the family. Since their reform and opening, family enterprises have achieved a leapfrog development, from weak to strong, and made important contributions to China&#x2019;s economic growth. Most of the first generation enterprise managers are nearly 60 years old. Many enterprises are facing urgent problems such as power transfer and leadership replacement. In family enterprises, the actual controller is the &#x201C;owner,&#x201D; while the professional manager is the &#x201C;shopkeeper.&#x201D; The &#x201C;family planning&#x201D; policy in 1982 affected many families, but the reproductive behavior of the actual controllers of family enterprises is still relatively special. Compared with ordinary people, they have a stronger reproductive desire and lower cost of extra birth. Hence, they often have more children (<xref ref-type="bibr" rid="B28">Guo, 2014</xref>). This creates the following questions: Will children&#x2019;s number of the actual controller affect the succession decision? and Will children&#x2019;s gender structure of the actual controller also affect the professional operation?</p>
<p>Succession decision refers to the decision of the actual controller to choose a successor; that is, the source of the final choice of successor (<xref ref-type="bibr" rid="B21">Deng et al., 2016</xref>). Theoretically, there are generally two sources of family business successors. One is to train children to succeed, and the other is to find professional managers from outside the enterprise (<xref ref-type="bibr" rid="B12">Chen and Ying, 2003</xref>). As a part of the characteristics of the actual controller, only a few scholars have paid attention to the relationship between the characteristics of the actual controller&#x2019;s children and the enterprise inheritance. On the one hand, the number of children affects the success rate and risk of enterprise inheritance (<xref ref-type="bibr" rid="B6">Bennedsen et al., 2005</xref>; <xref ref-type="bibr" rid="B28">Guo, 2014</xref>, <xref ref-type="bibr" rid="B29">2015</xref>). Particularly, the possibility of the existence of the enterprise in the form of family (<xref ref-type="bibr" rid="B22">Dou and Jia, 2008</xref>; <xref ref-type="bibr" rid="B48">Pan et al., 2019</xref>) and the degree of actual control efforts for the sustainable development of the enterprise (<xref ref-type="bibr" rid="B54">Shen and Chen, 2020</xref>). On the other hand, the gender of children may also have an impact on the inheritance of enterprises. <xref ref-type="bibr" rid="B32">Keating and Little (1997)</xref> pointed out that gender is an important standard for choosing successors. Under this standard, men often win, as even the eldest daughter is difficult to become the successor of the family enterprises. When the next generation of the family is only comprised of women, the probability of inheritance within the enterprise will be smaller. Notably, even some business owners would rather sell their businesses than pass them on to their daughters (<xref ref-type="bibr" rid="B6">Bennedsen et al., 2005</xref>; <xref ref-type="bibr" rid="B55">Shepherd and Zacharakis, 2017</xref>). The actual controllers are deeply influenced by China&#x2019;s concept of &#x201C;son inherits father&#x2019;s business&#x201D; and may strive to sire more boys to ensure the inheritance of his wealth when he is old (<xref ref-type="bibr" rid="B29">Guo, 2015</xref>). <xref ref-type="bibr" rid="B8">Bertrand et al. (2008)</xref> verified the impact of children&#x2019;s gender differences on the inheritance of business groups by using the data of Thai family enterprises. They found that the more male offspring there are in the family, the more likely is the family to develop a family enterprise group structure when inheriting. Although these studies have noticed that there is a certain relationship between the characteristics of children and the inheritance of enterprises, the existing studies on the internal mechanism of the selection of heirs of family enterprises mainly focus on the legal system, social environment, traditional culture, and the discussion of entrepreneurs&#x2019; growth experience in many aspects (<xref ref-type="bibr" rid="B39">Li, 2003</xref>; <xref ref-type="bibr" rid="B11">Chen and Wang, 2013</xref>; <xref ref-type="bibr" rid="B26">Giuliano and Spilimbergo, 2013</xref>; <xref ref-type="bibr" rid="B3">Ansari et al., 2014</xref>; <xref ref-type="bibr" rid="B5">Bennedsen et al., 2015</xref>; <xref ref-type="bibr" rid="B43">Lv et al., 2016</xref>). There is still a lack of research on the important factor of family that is emphasized in China&#x2019;s &#x201C;family culture&#x201D; on professional management.</p>
<p>In view of this, we use Chinese family listed companies from 2009 to 2019 as the research sample, and take the characteristics of the children of the actual controller as the explanatory variable to investigate its impact on professional management. The empirical test shows that (1) when the number of children of the actual controller is large, the possibility of selecting excellent successors and the degree of absorption of the specific knowledge of the actual controller increases. On the other hand, family enterprises have altruistic behavior. The increase in the number of children entering the enterprise drives closer the relationships between family members, which is conducive to the formation of a common vision of family members, reduces the risk of enterprise succession, and making the enterprise more likely to be internally inherited. (2) When the actual controller has more sons, the traditional &#x201C;son inherits the father&#x2019;s business,&#x201D; that is, male preference, enhances the actual controller&#x2019;s desire to continue the family business from generation to generation within the family. At the same time, the family authority will increase with the increase of sons, thereby inhibiting the professional operation of the enterprise the conceptual model of our study is shown in <xref ref-type="fig" rid="F1">Figure 1</xref>.</p>

</fig>
<p>The possible contributions of our study are as follows. We firstly discuss the factors affecting the appointment of professional managers in family enterprises from a new perspective of the characteristics of the children of the actual controller. Previous studies mostly discussed the influencing factors of professional operation of family enterprises from the aspects of external institutional environment, professional managers, and family enterprise governance structure (<xref ref-type="bibr" rid="B67">Zhang and Wang, 2010</xref>; <xref ref-type="bibr" rid="B11">Chen and Wang, 2013</xref>; <xref ref-type="bibr" rid="B3">Ansari et al., 2014</xref>), ignoring the influence of family background. Therefore, our study starts from the inside of the family, enriching the organization theory in the context of family business by establishing the logical relationship between the characteristics of the children of the actual controller and professional management decision-making. In addition, it is helpful to deeply understand the influence of endogenous factors on succession decision-making in family enterprises. Second, with further research, we expand the influence of children&#x2019;s gender on the decision-making of the actual controller. At the same time, we investigate the regulatory effect of the shareholding ratio of the actual controller, enriching the relevant literature of family business holding and help to deeply understand the impact of the actual controller&#x2019;s family on the succession of family business. Third, the research conclusion of our study provides reference value for family enterprises at the peak of inheritance. The succession process of family enterprises is synchronized with the development of business families, and the number of children will affect the inheritance planning of the first-generation entrepreneurs (Chen, 2003). Therefore, combined with the governance model of Chinese family enterprises, our study analyzes the impact of the characteristics of children of actual controllers on professional operation. Hence, it can be used as a reference for family enterprises to make succession planning at the peak of intergenerational inheritance easier, help to establish a modern enterprise system, build a harmonious &#x201C;collaborative symbiosis system&#x201D; of family governance and corporate governance, and promote the benign evolution and healthy and sustainable development of enterprises.</p>

<title>Literature Review and Research Hypothesis</title>
<p>&#x201C;The prosperity of the population and son, the prosperity of the country&#x201D; is contained in China&#x2019;s unique &#x201C;family&#x201D; culture, which makes the characteristics of children have a far-reaching impact on Chinese family enterprises (<xref ref-type="bibr" rid="B54">Shen and Chen, 2020</xref>). Parents&#x2019; upbringing of their children is a process of mutual influence and change (<xref ref-type="bibr" rid="B57">Steel et al., 1992</xref>). As the actual controller of the family business of parents, they are also the decision-makers of the enterprise (<xref ref-type="bibr" rid="B25">Du et al., 2019</xref>). Their behavior decisions include the future development and management strategy of the enterprise. Hence, management decisions will also be significantly affected (<xref ref-type="bibr" rid="B57">Steel et al., 1992</xref>; <xref ref-type="bibr" rid="B6">Bennedsen et al., 2005</xref>; <xref ref-type="bibr" rid="B18">Dahl et al., 2012</xref>).</p>
<sec id="S2.SS1">
<title>The Number of Actual Controller&#x2019;s Children and Professional Management</title>
<p>Regarding on what specific elements are needed to be inherited by the family, <xref ref-type="bibr" rid="B22">Dou and Jia (2008)</xref> found that entrepreneur tacit knowledge, entrepreneur relationship network, and entrepreneurship are the three types of elements that need to be inherited at the individual level of entrepreneurs in the process of intergenerational inheritance of family enterprises. Among them, the tacit knowledge of entrepreneurs is an important source of the competitiveness of family enterprises. Whether they can have this specific knowledge is very important to the success of the succession of successors (<xref ref-type="bibr" rid="B36">Lee et al., 2003</xref>; <xref ref-type="bibr" rid="B59">Tan and Fock, 2010</xref>; <xref ref-type="bibr" rid="B45">Minichilli et al., 2014</xref>). Since specific knowledge of family business is not institutionalized, this knowledge and ability must be inherited in long-term and frequent interactions (<xref ref-type="bibr" rid="B62">Williamson, 1979</xref>; <xref ref-type="bibr" rid="B14">Chrisman et al., 2017</xref>). Unlike professional managers, the children of the actual controller have inherent advantages in absorbing and acquiring the tacit knowledge of entrepreneurs. <xref ref-type="bibr" rid="B28">Guo (2014)</xref> found that compared with ordinary people, entrepreneurs have stronger desire to have children and lower costs of extra birth. Hence, there are very few private entrepreneurs who have only one child. For the actual controller who has only one child, the successor cannot fully absorb the knowledge of his parents without competition from other brothers and sisters and a lack of social trust in the external professional manager market. This because the risk of making its ability insufficient to manage family businesses is very large (<xref ref-type="bibr" rid="B28">Guo, 2014</xref>). The larger the number of children, the more will a successor actively participate in the operation and management of the enterprise in order to be recognized and take over the position. While trying to absorb the management experience of his parents, he will share new ideas with enterprise members, give a full play to his expertise, and reduce the transaction cost of specific knowledge. At the same time, it promotes the frequency of interaction and cooperation within the family (<xref ref-type="bibr" rid="B53">Shen and Cannella, 2010</xref>; <xref ref-type="bibr" rid="B2">Anderson et al., 2012</xref>), which makes the family provide more potential candidates for the enterprise, helps the actual controller to select excellent family successors to take appropriate positions, and reduces the risk of management failure, reducing the demand for professional managers in important positions such as chairman and general manager.</p>
<p>At the same time, the perspective of the family&#x2019;s social emotional wealth retention is a common perspective to explain family behavior. Not all family businesses take the maximization of economic interests as the only goal of the enterprise. In addition, most family businesses also pay attention to some non-economic goals that can cause the family to continue to develop (<xref ref-type="bibr" rid="B15">Chua et al., 2010</xref>). Family business has gradually become an important carrier of family members&#x2019; emotional sustenance and family culture. Maintaining social emotional wealth is the core concept of family business governance and decision-making (<xref ref-type="bibr" rid="B27">G&#x00F3;mez-Mej&#x00ED;a et al., 2007</xref>). Therefore, when considering the issue of family business successors, the ability of successors to make profits for the enterprise may not be as important as the harmonious relationship with family members, possibly affecting the selection of the next successor (<xref ref-type="bibr" rid="B56">Stavrou, 1999</xref>). The greater the number of children, the closer the relationship between family members, and the higher the degree of attachment to the family and organization. At the same time, relationships and attachments will be clearer, reminding family members of their identity in the family and business (<xref ref-type="bibr" rid="B66">Zellweger and Sieger, 2012</xref>), thereby promoting the frequent communication of family members in the management of the enterprise and enhancing their cooperation for the same interests (<xref ref-type="bibr" rid="B47">Mustakallio et al., 2010</xref>). During this period of cooperation, the joint operation of brothers and sisters creates more advantages in the modern fierce market competition (<xref ref-type="bibr" rid="B35">Lansberg, 1999</xref>), reducing the appointment of professional managers in the selection of successors to important positions.</p>

<title>The Proportion of Sons of Actual Controllers and Professional Management</title>
<p>As a part of the internal gender structure of the family, children&#x2019;s gender will affect the concept and behavior of family members. This is mainly reflected in parents&#x2019; investment, mental health, and savings in their children (<xref ref-type="bibr" rid="B13">Chen, 2016</xref>; <xref ref-type="bibr" rid="B24">Du and Zhang, 2018</xref>) and in the impact on parents&#x2019; decision-making. Scholars have found that in family businesses, it is difficult for even the eldest daughter to become a successor, especially when the next generation of the family is composed of only women. Hence, the probability of the enterprise passing on to the daughter is very small (<xref ref-type="bibr" rid="B6">Bennedsen et al., 2005</xref>; <xref ref-type="bibr" rid="B55">Shepherd and Zacharakis, 2017</xref>). <xref ref-type="bibr" rid="B61">Wang et al. (2019)</xref> included their son-in-law and daughter-in-law in the category of candidates for heirs in order to ensure the equality of gender and number of candidates when studying the candidates of the second generation heirs. The research results show that family businesses seem to prefer male heirs. <xref ref-type="bibr" rid="B28">Guo (2014)</xref> also found that only when the actual controller has no son or the son&#x2019;s ability is insufficient will he choose his daughter to take over.</p>
<p>On the one hand, in China&#x2019;s traditional inheritance system, only the successor of Zongyi can inherit property (<xref ref-type="bibr" rid="B20">Deng and Sang, 2016</xref>). The Chinese family continues the paternal generation relationship composed of male blood relatives. Therefore, only male offspring have the right to inherit Zongyi, and women are excluded from inheritance, resulting in the difference in the status of sons and daughters in the inheritance of family property (<xref ref-type="bibr" rid="B69">Zhang, 2002</xref>). The actual controller only makes decisions based on personal preferences. Therefore, under the influence of patriarchal culture and male preferences, when Chinese private entrepreneurs continue their family business, they first think of inheriting their father&#x2019;s business (<xref ref-type="bibr" rid="B42">Liu and Zhao, 2020</xref>). If the family only has daughters, the will of inheritance within the family may be missing. If there are more sons in the family, the actual controller will give more consideration to the continuity and inheritance of the family business (<xref ref-type="bibr" rid="B54">Shen and Chen, 2020</xref>). Hence, the willingness of inheritance within the family is strengthened and important positions are mainly held by the second generation, reducing the employment of professional managers.</p>
<p>On the other hand, based on gender role theory, male characteristics are more strong, decisive, ambitious, and challenging. In China&#x2019;s &#x201C;family culture,&#x201D; sons naturally have better force and deterrence than women, which may be useful to some regions and some people (<xref ref-type="bibr" rid="B13">Chen, 2016</xref>). At the same time, male heirs are generally in the center of ownership and control of enterprises or groups and have a crowding out effect on other family members. When there are multiple potential male heirs to choose from, it can not only meet the urgent desire of the actual controller to establish their own authority (<xref ref-type="bibr" rid="B8">Bertrand et al., 2008</xref>; <xref ref-type="bibr" rid="B46">Mishina et al., 2010</xref>), but also provide better personal and property protection for the family (<xref ref-type="bibr" rid="B13">Chen, 2016</xref>) and improve the ability and authority of family members to extract resources from the company (<xref ref-type="bibr" rid="B6">Bennedsen et al., 2005</xref>) to ensure the important position of the family in the enterprise. Therefore, the increase in the number of sons holding important positions, such as chairman and general manager, in the enterprise can ensure that the enterprise continues to exist in the form of a family business (Bertrand, 2008; <xref ref-type="bibr" rid="B22">Dou and Jia, 2008</xref>). Hence, the actual controller will reduce the employment of professional managers in important positions.</p>

<title>Sample Selection</title>
<p>We draw on the definitions of family business in relevant studies, such as <xref ref-type="bibr" rid="B58">Su and Zhu (2003)</xref> and <xref ref-type="bibr" rid="B64">Xu and Lv (2011)</xref>, as follows: (1) the ultimate controller can be traced to a natural person or family; and (2) the natural person or family has substantial control over the listed company. On January 1, 2008, China began to implement &#x201C;the labor contract law,&#x201D; which indicates that China&#x2019;s labor market has become more mature. As a special labor market, the manager market is also supervised and protected by &#x201C;the labor contract law&#x201D; and &#x201C;the labor law.&#x201D; With the development of the labor market, the manager market is also becoming more mature. Therefore, we selected the next year after the implementation of the labor contract law to start the research, selected the samples of Chinese listed companies that meet the definition of the family business from 2009 to 2019 China Stock Market and Accounting Research (CSMAR), and formed panel data. The selection is mainly carried out according to the following steps. Firstly, we obtained the samples of enterprises that actually control human beings as natural persons or families according to the database of Chinese listed family enterprises provided by CSMAR. Secondly, according to the information of actual controllers, we obtained the list of board members and senior management team members disclosed in the annual report of listed companies whose kinship is further determined by blood and marriage, along with the family business samples that meet the definition. Finally, we took the children of the actual controller in CSMAR as the proxy variable to measure. We then used these data to screen the second-generation family members who have entered the enterprise.</p>
<p>Our analysis treated the initial sample according to the following principles: (1) financial publicly traded firms are excluded; (2) newly publicly traded firms in the current year are excluded; (3) deleting firms with missing major data; (4) the firms with significantly abnormal values of each variable are eliminated; (5) the sample of special treatment (ST) firms are removed. The firm&#x2019;s financial data, governance performance, and basic firm data that were used are from CSMAR database. In addition, we excluded the samples of financial industry and missing data. In view of common practice, we searched Sina Finance, Oriental Wealth, Juchao information network, Baidu Finance, Baidu Encyclopedia, Baidu Post bar, Tianyan, and other websites and apps to manually supplement missing and suspicious data. Through the above screening steps, our analysis finally obtained 937 sample firms from 2009 to 2019, for a total of 5,564 samples. Excel and Stata15.0 were used to process the data during the research process. To avoid the influence of extreme values, the data was processed using Winsorize3%.</p>

<title>Profession</title>
<p>According to the CEO positions of family members (entrepreneurs and successors) and professional managers, <xref ref-type="bibr" rid="B9">Chen et al. (2013)</xref> divided family firms into Family CEO firms where family members serve as the CEO and Profession CEO firms where professional managers serve as the CEO. Based on this, we constructed the dummy variable &#x201C;<italic>Profession.</italic>&#x201D; If the firm does not introduce professional managers, we code it as 0.

<sec id="S3.SS2.SSS1.Px2">
<title>Degree</title>
<p><xref ref-type="bibr" rid="B16">Claessens et al. (2000)</xref> found that in publicly traded firms in East Asian countries, general manager and chairman of the board are the key positions of the firm, and they constitute the most basic and significant ladder team in Chinese firms. The chairman of the board is responsible for making major strategic directions on major issues, while the general manager is usually responsible for daily operations and the achievement of business objectives. Therefore, the chairman is usually more powerful than the general manager (<xref ref-type="bibr" rid="B31">Kato and Long, 2006</xref>). Based on this, we used &#x201C;<italic>Degree</italic>&#x201D; as the classification of the professional management degree according to the importance of professional managers&#x2019; positions. If the professional manager is neither chairman nor general manager, we code it as 0. If the professional manager only served as general managers, and the chairman of the board is a family member, we code it as 1. If the professional manager only serves as the chairman of the board and the general manager is a family member, we code it as 2. If the professional manager holds concurrent positions of chairman and general manager, we code it as 3.</p>

<p>This section shows the Pearson correlation coefficient matrix among <italic>dependent</italic>, <italic>independent variables</italic>, and main <italic>control variables</italic> in the study. <xref ref-type="table" rid="T3">Table 3</xref> reports the correlation coefficient among variables. In order to prevent multicollinearity from affecting the empirical regression results, the variance inflation factor (VIF) diagnosis is also adopted in our study. The VIF of explanatory variables are all less than 2, and the mean VIF of all variables is less than 2, eliminating the multicollinearity problem and ensuring the unbiased and consistent model estimation.</p>

<p><xref ref-type="table" rid="T4">Table 4</xref> presents the test results of <italic>Children</italic> and professional management (<italic>Profession</italic> and <italic>Degree</italic>). All the regression results of each column show that there is a significant negative correlation between the actual controller&#x2019;s number of children and professional management (<italic>Profession</italic> and <italic>Degree</italic>). First of all, it can be seen from <italic>Column (1)</italic> and <italic>Column (5)</italic> that the regression coefficients of <italic>Children</italic> and <italic>Profession</italic> is &#x2212;0.038, and that of <italic>Children</italic> and <italic>Degree</italic> is &#x2212;0.050, which are significantly negative in the statistical sense of 1%, indicating that <italic>Children</italic> are significantly negatively correlated with professional management (<italic>Profession</italic> and <italic>Degree</italic>) without the addition of other major control variables. As <italic>Children</italic> increases by one unit, <italic>Profession</italic> decreases by 0.038 units and <italic>Degree</italic> decreases by 0.05 units. After adding the characteristic variables of corporate finance, corporate governance, family, and actual controller in the <italic>Column (2)</italic>, <italic>Column (3)</italic>, and <italic>Column (4)</italic>, respectively, it is found that the coefficient of <italic>Children</italic> and <italic>Profession</italic> is always significantly negative at the level of 1%. After the addition of the characteristic variables of corporate finance and corporate governance in <italic>Column (6)</italic> and <italic>Column (7)</italic>, respectively, <italic>Children</italic> and <italic>Degree</italic> are always significantly negative at the level of 5%. In <italic>Column (8)</italic>, although <italic>Children</italic> and <italic>Degree</italic> are affected by the characteristic variables of family and actual controller, they still show a significant negative correlation. In addition, it can be seen from <italic>Column (4)</italic> and <italic>Column (8)</italic> that as <italic>Children</italic> increases by one unit, <italic>Profession</italic> and <italic>Degree</italic> decreases by 0.035 and 0.037 units, respectively, and <italic>Children</italic>&#x2019;s influence on <italic>Profession</italic> is greater than that on <italic>Degree.</italic> On the one hand, this result is due to the increase in the number of children, the tacit knowledge of the actual controller that can be fully absorbed (<xref ref-type="bibr" rid="B65">Yu et al., 2013</xref>), and how the actual controller is more likely to select excellent children, reducing the risk of children&#x2019;s succession (<xref ref-type="bibr" rid="B28">Guo, 2014</xref>). On the other hand, the increase in the number of children promotes the interaction frequency of family members in the management of the enterprise, causing the relationship between family members to be closer (<xref ref-type="bibr" rid="B47">Mustakallio et al., 2010</xref>; <xref ref-type="bibr" rid="B66">Zellweger and Sieger, 2012</xref>), thereby helping in making consistent decisions for a common vision. That is, the more children of the actual controller of the family business enters the enterprise, the stronger the inhibition of professional operation. Therefore, Hypothesis 1 is supported.</p>

<sec id="S4.SS3.SSS2">
<title>The Proportion of the Sons of Actual Controllers and Professional Management</title>
<p><italic>Hypothesis 2</italic> predicts that in family firms, there is a negative correlation between the proportion of sons of actual controllers and professional management. This part verifies this conclusion on the basis of controlling related factors. To ensure robustness of the results, <italic>Column (1)</italic> and <italic>(5)</italic> of <xref ref-type="table" rid="T5">Table 5</xref> only controls the <italic>Industry</italic> and <italic>Year two</italic> dummy variables. On this basis, the firm&#x2019;s financial characteristic variables are added in <italic>Column (2)</italic> and <italic>Column (4)</italic> of <xref ref-type="table" rid="T5">Table 5</xref>. Then, corporate governance characteristic variables are added to <italic>Column (3)</italic> and <italic>(7)</italic> of <xref ref-type="table" rid="T5">Table 5</xref>. Finally, the characteristic variables of family and actual controller are further added in <italic>Column (4)</italic> and <italic>(8)</italic> of <xref ref-type="table" rid="T5">Table 5</xref>, and the regression results are shown in <xref ref-type="table" rid="T5">Table 5</xref>.</p>

<p><xref ref-type="table" rid="T5">Table 5</xref> presents the test results of <italic>SonProp</italic> and professional management (<italic>Profession</italic> and <italic>Degree</italic>). The regression results in <italic>Columns (1)</italic> to <italic>(4)</italic> show that there is a significant negative correlation between <italic>SonProp</italic> and <italic>Profession</italic> at 1% level, while <italic>Columns (2)</italic> to <italic>(8)</italic> show that <italic>SonProp</italic> has no significant correlation with <italic>Degree</italic>. As can be seen from the <italic>Column (1)</italic>, the regression coefficient of SonProp is &#x2212;0.051, which is statistically significant at 1%, indicating that as the <italic>SonProp</italic> increases by one unit, <italic>Profession</italic> decreases by 0.051 units. After adding the characteristic variables of corporate finance, corporate governance and family, and actual controller in <italic>Column (2)</italic>, <italic>(3)</italic>, and <italic>(4)</italic>, respectively, it is found that the coefficients of <italic>SonProp</italic> and <italic>Profession</italic> are significantly negative at the 1% level. Finally, <italic>Column (4)</italic> shows that for every unit added to <italic>SonProp</italic>, <italic>Profession</italic> decreases by 0.055 units.</p>
<p>On the one hand, under the influence of China&#x2019;s traditional concept of &#x201C;son inherits father&#x2019;s business,&#x201D; the more sons, especially adult sons, in the family, the more the actual controller will take into account the continuation and inheritance of the family business and show a strong willingness to inherit internally (<xref ref-type="bibr" rid="B54">Shen and Chen, 2020</xref>), inhibiting professional management. On the other hand, when there are multiple potential male heirs to choose from, the actual controller has a more urgent desire to establish his own authority. The increase in the number of sons holding important positions provides the actual controller with the possibility of establishing authority, thus reducing the employment of professional managers. Therefore, Hypothesis 2 is supported.</p>

<title>Change the Sample Size</title>
<p>According to the data of &#x201C;the report on the inheritance of Chinese family&#x201D; enterprises released in 2015, 15% of the second generation clearly expressed their unwillingness to take over, another 45% of the second generation did not have a clear attitude towards taking over, and only 40% of the second generation clearly expressed their willingness to take over. It can be seen that the willingness of children to take over has decreased in recent years. In order to test whether our research results are still applicable in recent years, we firstly use the method of changing the sample time to separately select the recent samples from 2015 to 2019. Afterwards, we carried out robustness tests on the relationship between the characteristics of actual controller&#x2019;s children and professional management. The test results are shown in <xref ref-type="table" rid="T6">Tables 6</xref>, <xref ref-type="table" rid="T7">7</xref>.</p>

<title>Replacement of Control Variables</title>
<p>In order to ensure the robustness of the results, we used the method of replacing partial control variables. Referring to the research of <xref ref-type="bibr" rid="B9">Chen et al. (2013)</xref>, <xref ref-type="bibr" rid="B37">Li et al. (2014)</xref>, <xref ref-type="bibr" rid="B70">Zhao and Lv (2017)</xref>, in terms of corporate finance, we replaced the <italic>Roa</italic> with the net profit margin of total assets (<italic>Roe</italic>). The calculation method was <italic>Roe</italic> = (net profit)/(total assets balance). In terms of corporate governance, the <italic>Independent board</italic> was replaced by institutional investor ownership ratio (<italic>Inst</italic>). At the level of family and actual controller characteristics, <italic>Establish</italic> was replaced with family time (<italic>Family year</italic>), and the calculation method was <italic>Family year</italic> = ln (statistical date &#x2212; family date + 1). Robustness test was conducted on the relationship between the characteristics of actual controller&#x2019;s children and professional management. The test results are shown in <xref ref-type="table" rid="T8">Tables 8</xref>, <xref ref-type="table" rid="T9">9</xref>. It can be seen that there is no difference in the test results as a whole, which proves that the regression result of the relationship between the characteristics of actual controller&#x2019;s children and the professional management is robust.</p>

<title>Further Study</title>
<p>The previous study found that the characteristics of children of actual controllers were significantly negatively correlated with professional management. In this part, we tested the impact of the number of sons and daughters of actual controllers on professional management, and the effect of ownership ratio of actual controllers on the number of children and professional management.</p>

<title>Number of Sons, Number of Daughters, and Professional Management</title>
<p>It has been verified above that both <italic>Children</italic> and <italic>SonProp</italic> are significantly negatively correlated with professional management (<italic>Profession</italic> and <italic>Degree</italic>). In this part, we use <italic>Sonnum</italic> for the number of sons, and <italic>Girlnum</italic> for the number of daughters to reflect the difference between the number of children&#x2019;s gender and professional management relationship. This will be verified on the basis of controlling related variables.

On this basis, the firm&#x2019;s financial characteristic variables are added in <italic>Columns (3)</italic> and <italic>(4)</italic>. Then, corporate governance characteristic variables are added in <italic>Columns (5)</italic> and <italic>(6)</italic>. Finally, the characteristic variables of family and actual controller are added in <italic>Columns (7)</italic> and <italic>(8)</italic>. The regression results are shown in <xref ref-type="table" rid="T10">Tables 10</xref>, <xref ref-type="table" rid="T11">11</xref>.</p>

According to <xref ref-type="table" rid="T10">Tables 10</xref>, <xref ref-type="table" rid="T11">11</xref>, <italic>SonNum</italic> is more significantly related to professional management than <italic>GirlNum</italic>. This result is mainly due to the fact that the actual controller is influenced by the traditional Chinese concept of male preference, and that sons naturally have better force and deterrence than women (<xref ref-type="bibr" rid="B13">Chen, 2016</xref>), which reduces the risk of enterprise inheritance and affects the actual controller in appointing professional managers to important positions.</p>
</sec>
<sec id="S4.SS5.SSS2">
<title>The Moderation Effect of Actual Controller&#x2019;s Ownership</title>
<p>The strong relationship characteristics of Chinese family enterprises exacerbate the phenomenon of centralization of power (<xref ref-type="bibr" rid="B40">Li and Chen, 2005</xref>). The actual controller has the de facto ownership and control of the company, providing an important impact on the company&#x2019;s governance and decision-making (<xref ref-type="bibr" rid="B60">Wang et al., 2007</xref>). Will the ownership proportion of the actual controller have an impact on the relationship between the number of children and professional management? This section discusses this problem.</p>
<p>With the improvement of the degree of marketization, family enterprises are more inclined to have a lasting foundation. The higher the family shareholding, the more consistent the family interests are with the enterprise interests (<xref ref-type="bibr" rid="B51">Shao and Lv, 2015</xref>; <xref ref-type="bibr" rid="B41">Liu and Lv, 2016</xref>). The inheritance of family enterprises pays more attention to control rather than simply changing leaders. It will have a far-reaching impact on the behavior and performance of family businesses (<xref ref-type="bibr" rid="B52">Sharma and Carney, 2012</xref>). In terms of the number of children, <xref ref-type="bibr" rid="B8">Bertrand et al. (2008)</xref> found that there is a strong positive correlation between family ownership and the number of enterprise family members. Due to the emotional preference of altruism, the actual controller of the enterprise tends to absorb the relatives of immediate blood relatives (birth relationship) to jointly manage the enterprise (<xref ref-type="bibr" rid="B48">Pan et al., 2019</xref>). In terms of the number of sons, with the increase of the number of sons, the number of &#x201C;available&#x201D; people in the family and the number of family members with shares in the enterprise are increased. The actual controller can take advantage of the &#x201C;crowding out&#x201D; effect of sons on the ownership and control of other family members in the company (<xref ref-type="bibr" rid="B8">Bertrand et al., 2008</xref>) to obtain a greater proportion of ownership to improve the influence of their families on the company&#x2019;s decision-making (<xref ref-type="bibr" rid="B10">Chen, 2011</xref>). Therefore, in the process of power transfer, the actual controller has more ownership. On the one hand, the greater the power to act in the way of increasing emotional value gives the owner a greater ability to bring more family members into the enterprise, thereby maintaining family control over it (<xref ref-type="bibr" rid="B19">Demsetz and Lehn, 1985</xref>; <xref ref-type="bibr" rid="B50">Schepers et al., 2014</xref>; <xref ref-type="bibr" rid="B4">Bauweraerts and Colot, 2017</xref>). On the other hand, regarding family reputation, the smaller the impact of nonfamily members on social status and social capital (Xu and Nannan, 2014), the smaller the risk of intergenerational inheritance when inheritance is transmitted within the family. Therefore, to maintain and protect the family&#x2019;s social emotional wealth, the actual controller increases the number of children and the proportion of sons entering the enterprise, avoiding employing the actual controller to hold important positions.</p>
<p>As far as professional managers are concerned, the degree of marketization in China is low, and the relevant legal system is not perfect (<xref ref-type="bibr" rid="B61">Wang et al., 2019</xref>). Family enterprises are still very worried about the moral hazard of professional managers. In addition, the highly centralized power gives family members greater responsibilities and obligations, making family businesses take a very cautious attitude in risky decision-making (<xref ref-type="bibr" rid="B38">Li and He, 2012</xref>). Therefore, with the increase of the ownership of the controlling family, family interests are highly related to the listed company, and more attention will be paid to the production and operation activities of the enterprise. Under the same conditions, the possibility of arranging professional managers to take important positions in the listed company will be reduced (<xref ref-type="bibr" rid="B68">Zhang, 2015</xref>).</p>
<p>Based on the above analysis, we use <italic>Children</italic> and <italic>SonProp</italic> as independent variables, <italic>Profession</italic> and <italic>Degree</italic> as dependent variables, and adopt hierarchical regression method to test the role of <italic>Ownership</italic>. The results are shown in <xref ref-type="table" rid="T12">Tables 12</xref>, <xref ref-type="table" rid="T13">13</xref>.</p>

<p><xref ref-type="table" rid="T12">Tables 12</xref>, <xref ref-type="table" rid="T13">13</xref> present that the actual controller will consider ownership ratio as one of the factors when making successor selection decisions. Family firms&#x2019; decisions are often influenced by the social emotional wealth of family control and influence (<xref ref-type="bibr" rid="B27">G&#x00F3;mez-Mej&#x00ED;a et al., 2007</xref>; Zellweger and Astrachan, 2008), and family ownership, as a part of social emotional wealth, is positively correlated with the number of family members (Bertrand, 2008). That is, the larger the ownership proportion of actual controllers, the more relatives with direct blood relatives will be recruited to jointly govern firms with the actual controller (<xref ref-type="bibr" rid="B48">Pan et al., 2019</xref>). At the same time, with the increase of the proportion of sons, their &#x201C;crowding out&#x201D; effect on the ownership of other family members in the company increases (Bertrand, 2008), improving the influence of the actual controller on the company&#x2019;s decision-making (<xref ref-type="bibr" rid="B10">Chen, 2011</xref>). Therefore, in the process of power transfer, the ownership of the actual controller increases, and the greater its power to act in the way of increasing emotional value, giving the owner a greater ability to bring more family members into the enterprise. In order to maintain the family&#x2019;s control over the enterprise, reduce the risk of intergenerational inheritance of the scepter within the family, and maintain and protect the social emotional wealth of the family and its cautious decision-making attitude (<xref ref-type="bibr" rid="B38">Li and He, 2012</xref>), the actual controller will increase the number of children and the proportion of sons entering the enterprise and reduce the employment of professional managers when making decisions. Therefore, with the increase of the ownership proportion of the actual controller, the negative correlation between the characteristics of children and the professional operation of enterprises will be strengthened, and the result is in line with the prediction of our study.</p>

<title>Conclusion</title>
<p>At present, Chinese family enterprises have successively entered the peak of shift handover. Whether family enterprises choose internal inheritance or external professional managers, previous studies mostly discussed the influencing factors of professional management of family enterprises from the aspects of external institutional environment, professional managers, and family enterprise governance structure, ignoring the impact of the family endogenous factor of the actual controller on the appointment of professional managers. The actual controller of family enterprises, as the decision-maker of enterprises, under the background of the concept of &#x201C;prosperity of people and prosperity of the country&#x201D; in Chinese traditional culture, show how the characteristics of children will have an impact on their behavior and concept. Taking Chinese family listed companies as samples, we test the relationship between the characteristics of the children of the actual controller and professional management from two aspects: the number of children and the proportion of sons of the actual controller. It is found that there is a significant negative correlation between the characteristics of children of actual controllers and professional management. Specifically, when there are large numbers of children, on the one hand, the possibility of selecting excellent successors and the degree of absorption of the specific knowledge of the actual controller increases. On the other hand, the altruistic tendency of the family business makes the family members more closely connected, which is conducive to the family members to form a common vision and reduce the risks in the process of business succession. The strengthening of the internal inheritance will of the actual controller inhibits the professional operation of the enterprise. Influenced by the traditional concept of &#x201C;son inherits father&#x2019;s business&#x201D; and male preference, the actual controller will give more consideration to the continuation and inheritance of family business. At the same time, the increase in number of sons makes it easy for the family to establish authority in the enterprise, and the reduction of internal succession risk has a strong inhibitory effect on professional operation. In further research, we found that sons have a more significant impact on professional management than daughters. At the same time, the greater the ownership proportion of the actual controller, the stronger the correlation between children&#x2019;s characteristics and professional management.</p>
<p>Our conclusion provides evidence for the exploration of the relationship between the characteristics of the actual controller&#x2019;s children and succession decision-making. Theoretically, on the one hand, it enriches the organization theory in the context of family business, expands the theoretical gap of the logical relationship between the actual controller&#x2019;s family population structure and enterprise succession decision-making, and enriches the research on the antecedent variables of successor identity. Different from the previous research on the exogenous factors affecting professional operation, by establishing the relationship between the characteristics of the children of the actual controller and the enterprise succession decision, we expand the research on the influencing factors of family business succession from the perspective of family, which is helpful to deeply understand the influence of the endogenous factors of family business on the succession decision. On the other hand, in the further research, we will examine the regulatory effect of the actual controller&#x2019;s shareholding ratio to enrich the relevant literature of family business holding and help deeply understand the impact of the actual controller&#x2019;s family on the succession of family business. The practical significance of our study is that although the &#x201C;family&#x201D; management model may interfere with the effective governance of the company from a rational perspective, the starting point of the actual controller&#x2019;s decision-making will still be affected by the traditional Chinese &#x201C;family&#x201D; culture. The succession process of family business is synchronized with the development of business family. It runs through the whole process, from the actual controller of the enterprise to the completion of the handover of leadership. Therefore, combined with the governance model of family enterprises, our study analyzes the impact of the characteristics of the children of the actual controller on professional operation, which is of significant reference for family enterprises to make succession planning at the peak of intergenerational inheritance, and helps to establish a modern enterprise system, promotes the benign evolution of enterprises, builds a harmonious &#x201C;collaborative symbiosis system&#x201D; of family governance and corporate governance, and promotes the healthy and sustainable development of private enterprises.</p>
