An Empirical Research on the Comprehensive Bonded Zones Improving Green Technology Innovation Effect of Urban Enterprises
Comprehensive bonded zones(CBZs)improve the green technology innovation(GTI)effect of urban enterprises while promoting the outward-oriented transformation of the economy with its function as a platform for expanding the opening-up policy.We empirically examine the association between the establishment of CBZs and the GTI effect of urban enterprises with panel data of prefecture-level cities and above in mainland China from 2005 to 2021,using difference-in-difference(DID)method.The empirical results confirm that the establishment of CBZs promote the GTI effect of enterprises in the host city;the institutional demonstration effect and industrial structure upgrading effect of CBZs are positively related to the GTI effect of enterprises in the host cities,while the FDI technology spillover effect of CBZs is negatively related to the GTI effect of enterprises in the host cities;the correlation between CBZs and the GTI effect of urban enterprises shows heterogeneity depending on the geographic location,hierarchy level,and scale of the city where the CBZs are established;there is some degree of negative spatial externality in the impact of CBZs on the GTI effect of urban enterprises.This study focuses on the multiple functions of CBZs through the integration of various types of special customs supervision zones on how to influence the GTI effect of urban enterprises,and reveals the influence mechanisms between the establishment of CBZs and the GTI effect of urban enterprises through the empirical test.The conclusions help to provide the theoretical basis for the state to authorize the establishment of comprehensive bonded zones,as well as the relevant departments to formulate the specific policies of CBZs,and the urban enterprises to make full use of CBZs to improve the GTI effect.
