How Does Institutional Opening-up Affect Regional Innovation Vitality—An Empirical Research Based on Individual Patent Data from 2010 to 2020
Innovation is a key feature of new quality productivity and the primary driving force behind economic and social development,requiring long-term inputs of mate-rial and human capital.As a vital component of the national innovation system,regional innovation system takes advantage of the construction of pilot free trade zones to agglomer-ate strategic emerging industries and innovative production factors,thereby boosting inno-vation vitality.Using individual patent data from 2010 to 2020,this study constructs a multi-period difference-in-differences model within the framework of agglomeration econo-my theory,treating the phased establishment of pilot free trade zones as a quasi-natural experiment.We empirically examine the impact and mechanisms of pilot free trade zones on regional innovation vitality.Results show that the construction of pilot free trade zones promotes regional innovation vitality.The effects of industrial agglomeration,capital ag-glomeration,and talent agglomeration are the channels through which these impacts occur.Institutional innovation strengthens the positive effect of pilot free trade zones on regional innovation vitality.Counterfactual and heterogeneous analyses reveal that the innovation effects of pilot free trade zones vary by establishment phase,strategic planning,local char-acteristics,inventor's affiliation,and industry.The conclusions of this paper offer valuable policy insights for optimizing pilot free trade zone construction,capitalizing on the innova-tion benefits of high-level opening-up,and further advancing new quality productivity for high-quality development.
