Abstract:Based on the panel data of 31 provinces (autonomous regions and cities) in China from 2005 to 2019, this paper empirically analyzes the impact of marketization degree, financial development level and entrepreneurship on regional innovation ability by constructing dynamic panel model and threshold panel model. It is found that both the degree of marketization and the level of financial development can significantly promote the regional innovation ability, and the impact of the degree of marketization on the regional innovation ability is stronger than the level of financial development; Entrepreneurship is the intermediary variable of the impact of financial development level and marketization degree on regional innovation ability, and has complete intermediary effect and threshold effect. After replacing the estimation method and corresponding variable measurement indicators, the result is still robust. Finally, based on the conclusion of empirical analysis, this paper puts forward corresponding policy suggestions.
