Abstract:In the analysis, we integrated stakeholder and agency theories to explore the connection between corporate social responsibility (CSR) and sustainable financial development by considering the moderating effect of ownership structure. After empirical analysis, we found the following conclusions. First, the short-term and long-term economic performance is positively affected by CSR, which leads to sustainable financial development. Second, ownership circulation has a positive relationship with economic performance in the short run, which short-term profit increases as ownership circulation strengthens. Third, the effect of CSR on short-term economic performance is moderated by ownership structure. Excessive concentrated ownership may lead to decisions that do not satisfy all key stakeholders and may reduce the positive effect of CSR on economic performance. Finally, we suggest that Chinese energy companies should pay more attention to improving corporate social responsibility to maintain good economic performance and develop sustainable competitive advantage. Meanwhile, companies should optimize ownership concentration to avoid weakening the positive effects of social responsibility on short-term economic performance.
