Abstract:Digital government construction has become an important part of China"s administrative system reform and national governance system modernization construction, so how to take government digital transformation as an opportunity to enhance regional innovation capacity is a major issue facing local governments. Based on the provincial panel data from 2014-2021, the impact of government data opening on regional innovation and its mechanism of action are explored. The empirical results show that government data openness can significantly improve regional innovation capacity, moreover, the degree of data openness can have an impact on regional innovation capacity through the convenience of government services. The mechanism of action is that government data openness improves the efficiency of service operation, reduces the repetition rate and error rate, improves the synergy of data sharing and thus stimulates the convenience potential of government services, accelerates the follow-up of market players and thus empowers regional innovation. At the same time, regional characteristics affect the extent to which government data openness can play a role, with regions with higher efficiency benefiting more from the development of government data openness than central regions that demonstrate and promote the role of government services.
