Institutional Investor Networks and ESG Performance: Evidence from China

This paper examines whether and how the network centrality of institutional investors affects firms' sustainability development. Using data from the Chinese market, we find that central institutional investors in the social network significantly increase firms' overall ESG performance. For the environmental, social, and governance pillars of ESG, we find that environmental performance is more likely to be driven by central institutional investors. We further show that central institutional investors act as active monitors and resource providers, enhancing firms' ESG performance by improving corporate internal control quality, promoting the corporate information environment, alleviating financing constraints, and increasing green innovation capability. Furthermore, the relationship between centrality and ESG performance is considerably more pronounced for firms with political connections or under a high degree of industry competition but more diminished in periods of high economic policy uncertainty.
