Abstract:

The report of the 20th National Congress of the Communist Party of China has pointed out that high-quality development is the primary task of comprehensively building a modern socialist country. Regional green innovation is the essence of high quality development, but there is still a lack of systematic and in-depth research on whether the collaborative development of urban agglomerations can bring about the green innovation effect. Therefore, based on the perspective of the urban agglomeration economic coordination committee, this paper evaluates the impact of coordinated development policy of urban agglomeration on green innovation by the green patent data and the PSM-DID method, and tests the robustness by using different matching strategies and eliminating the interference of urban scale. Results are as follows. The collaborative development of urban agglomerations significantly promotes regional green innovation, and the promotion of invention green patents is stronger than that of utility model green patents. The coordinated development of urban agglomerations shows significant incentive effect on the green innovation of both newly joined cities and existing joined cities. The incentive effect on the green innovation of existing joined cities is more obvious than newly joined cities. The intermediary effect test shows that the coordinated development of urban agglomerations can stimulate the green innovation by strengthening environmental regulation, weakening decentralization competition, promoting industrial upgrading and strengthening information density. The coordinated development of urban agglomerations influences the green innovation of newly joined cities more by promoting industrial upgrading and weakening the decentralized competition, and influences the green innovation of existing joined cities by enhancing environmental regulation and information density.In the future, we should further improve the system and mechanism for coordinated development of green innovation, adopt differentiated policies, strengthen the construction of supporting social public service systems and cultural atmosphere environment, and promote the ecological and green integrated development of urban agglomerations in China.

Key words: coordinated development of urban agglomeration, green innovation, urban economic coordination council, high quality development
