The Impact of Social Security Fund Investment on Corporate ESG Performance

As an important component of the capital market, the investment behavior of social security funds has increasingly drawn attention for its impact on corporate ESG performance. Based on data from publicly listed companies in China, this paper explores the influence of social security fund investment with respect to corporate ESG performance and its core mechanisms. The study finds that social security fund investment effectively enhances corporate ESG integration. Heterogeneity tests show that the relationship between the two varies across aspects such as auditor quality, information transparency, and analyst attention. This paper provides policy insights for optimizing social security fund investment strategies and enhancing corporate sustainability.
