“…However, previous studies have paid more attention to the relationship between green innovation performance and operating profit, profitability and innovation performance, while the research on internal factors of green innovation performance of enterprises is less. At the same time, due to the concentration of equity in some listed companies, shareholders with large equity shares often make biased decisions in order to safeguard their own interests, which affect the level of green innovation performance of enterprises, or affect market performance by changing green innovation performance to achieve profits [2] . Based on the above analysis, this paper selects relevant data from 2010 to 2020 to explore the relationship between equity concentration, enterprise growth and green innovation performance of listed companies through theoretical analysis and empirical testing, focusing on the intermediary role of enterprise growth in the process of equity concentration affecting market performance, with a view to providing strong empirical evidence for the research on influencing factors of market performance, And put forward targeted policy recommendations.…”
