Evaluating the Influence of Environmental, Social, and Governance (ESG) Performance on Green Technology Innovation: Based on Chinese A-Share Listed Companies

In the context of the rapid development of the global economy, promoting corporate economic development while taking into account sustainable development has gradually become the focus of attention of countries around the world. The ESG performance reflects the differences in the assessment of enterprises’ sustainable development potential by capital market information intermediaries. These differences affect the internal governance and external financing of enterprises, thereby influencing corporate green innovation. This research is based on 1500 Shanghai-Shenzhen A-share listed companies in China from 2012 to 2022. Using green technology innovation quantity (GINUM) and green technology innovation quality (GICIT) as the measures of corporate green innovation capabilities, and by constructing a DiD model and a benchmark regression model, the dynamic relationship between ESG performance and green innovation is explored. At the same time, the mediation effect model is introduced to examine the impact of ESG performance on corporate green innovation capabilities from three perspectives: financing constraints, management’s green development awareness, and employee innovation efficiency. In addition, endogenous analysis methods and robustness test methods are employed to further ensure the reliability of the research results. The research findings show that ESG performance can significantly promote corporate green innovation capabilities. Heterogeneity analysis reveals that ESG performance significantly enhances the green technology innovation capabilities of enterprises, especially among non-state-owned small and medium-sized enterprises (SMEs) and enterprises in the eastern region. The regression coefficients for GINUM and GICIT are 0.019, 0.021, 0.084, and 0.086, respectively, all of which are statistically significant at the 1% level. The mechanism analysis shows that in terms of alleviating financing constraints, enhancing management’s green development awareness, and improving employee innovation efficiency, the regression coefficients of ESG performance for GINUM and GICIT are −1.559, −1.953, 0.018, 0.011, 0.427, and 0.495, respectively, indicating a certain promoting effect. The results of this study enrich and expand the relevant research on the relationship between ESG and corporate green innovation capabilities to a certain extent. This research is expected to provide some new practical directions for promoting green innovation capabilities within the ESG framework.
