Abstract Taking A-share listed companies from 2011 to 2018 as samples, this paper empirically tests the impact of local official turnover on corporate green innovation, and further examines the role of political connections. The results show that under the current system of administrative decentralization and official promotion tournament in China, the policy discontinuity caused by local officials’ turnover has a significant negative impact on corporate green innovation, and the effect is more obvious in the politically related enterprises than that of non-political affiliated enterprises. Further mechanism test results show that the two channels of this impact are to intensify the environmental uncertainty faced by enterprises and reduce the local environmental supervision. The conclusion of the study has a certain reference value for understanding of the impact of government behavior and political connections on corporate environmental protection activities from a micro point of view.
