Green bonds are a financial instrument that has been vigorously promoted in the field of green finance in recent years, and the green bond market in China has been developing rapidly since 2016. In this paper, 61 listed companies that issued green bonds from 2016‐2021 are used as research objects, and the impact of issuing green bonds on the performance of listed companies is studied using a multi‐temporal double difference model based on the panel data of listed companies. The results show that issuing green bonds has a positive impact on the performance of listed companies and can significantly improve the total return on assets of companies. Therefore, the green bond market system should be continuously improved and the scale of green bond development should be expanded in order to increase the enthusiasm of enterprises to issue green bonds.
