Methods: A stratified sampling method was adopted to select 1500 primary care providers from cities in Heilongjiang Province, China, using the gross domestic product development level of each city as a basis. A questionnaire survey was conducted (effective response rate = 85.8%), and one-way analysis of variance or independent sample t-test, Pearson correlation, and linear regression were used to analyse the factors related to primary care providers’ job performance. Results: Among the primary care providers who participated in this survey, the mean job performance score was 22.189 (SD=7.695). The job performance score of primary care providers was positively correlated with a job satisfaction score of 37.587 (SD=15.001) (r=0.574, p<0.001), and was also positively correlated with a social support score of 33.036 (SD=12.851) (r=0.534, p<0.001). Model 2 results showed that job satisfaction and job performance were positively correlated (β=0.301, p<0.001). The regression relationship explains that 34.3% of the variation in the dependent variable. Model 3 shows that professional titles, job satisfaction, and social support are the main factors that affect the performance of primary care providers. Conclusions: The job performance of primary care providers in Heilongjiang Province in China is low, and their job titles, job satisfaction, and social support are all related factors. It is necessary to provide assistance to primary care providers in terms of family, organisation, society, policy, etc., to improve their job performance, and to better provide high-quality health services to the grassroots.
