Research On The Influence Of Digital Inclusive Finance On The Complexity Of Export Technology

It is necessary to continuously improve the technical complexity of export products and realize the transformation and upgrading of exports.Based on the panel data of cities above the prefecture level in China from 2011 to 2017,this thesis collects the digital inclusive finance index and establishes a panel fixed effect regression model,controls the annual fixed effect and urban fixed effect,and uses the method of gradually adding control variables to conduct benchmark regression.The research results indicate that the development of digital inclusive finance has significantly promoted the development of urban export technology complexity.Considering the endogenous problems caused by mutual causality and missing variables,this thesis constructs a 0-1 dummy variable as an instrument variable of digital inclusive finance based on the "Broadband China" strategy.The regression results of instrumental variables show the robustness of the results in this thesis.Considering the impact of clustering and different city levels,this thesis also conducts robustness tests by clustering at different levels and deleting municipalities directly under the central government.The results still show that digital inclusive finance can significantly promote the improvement of export technology complexity.Structural analysis shows that the impact of digital inclusive finance on the complexity of export technology is mainly reflected in the coverage of digital inclusive finance.The depth of use and degree of digitization of digital inclusive finance have no significant impact on the complexity of urban export technology.Mechanism analysis shows that digital inclusive finance mainly promotes the improvement of local financial level and the advancement of regional industries,thereby increasing the complexity of urban export technology.Heterogeneity analysis shows that the impact of digital inclusive finance on the complexity of urban export technology is more driven by inland regions,and its impact on the complexity of export technology in coastal areas is not significant.Meanwhile,the impact of digital inclusive finance on the complexity of export technology mainly occurs in non resource-based cities,and the impact of digital inclusive finance on the complexity of export technology is not significant in resource-based cities.
