A Study on the Influence of the Opening of China Railway Express on the Upgrading of China's Cities Export Structure
This paper empirically examines the impact of the opening of China Railway Express on up-grading the cities export structure by using the DID Mode and discusses the relevant mechanism behind it.The research shows that:firstly,the opening of China Railway Express in cities has significantly promoted the upgrading of urban export structure,and the research results are still significant under a variety of ro-bustness test methods;secondly,the mechanism test shows that the improvement of resource allocation efficiency and the improvement of regional innovation level are effective ways for cities to promote the up-grading of export structure.Further analysis shows non-equilibrium characteristics in the opening of China Railway Express.This study found that western cities,non-resource cities,and central node cities are more likely to receive policy dividends.
