This study is based on data from Chinese listed companies from 2013 to 2023, utilizing web scraping technology to extract corporate announcements and employing a cross-border e-commerce keyword dictionary to identify specific time points when companies engaged in cross-border e-commerce activities. These time points are treated as policy shock events, and a difference-in-differences model is employed for empirical analysis. The findings reveal that engaging in cross-border e-commerce significantly enhances a company’s level of green innovation. Mechanism analysis indicates that cross-border e-commerce indirectly promotes increases in green patent applications by alleviating firms’ financial constraint and promoting their digital transformation, while environmental information disclosure also plays a positive moderating role. Heterogeneity analysis shows that this promotional effect is more pronounced among high-tech enterprises, firms in high-pollution industries, large state-owned enterprises, and companies in China’s central and western regions. The study’s conclusions provide a reference for enterprises to achieve sustainable development through cross-border e-commerce activities.
