| With the implementation of the reforn and opening up policy in 1978,the economy has achieved rapid development and the quality of life of the people has been increasing.However,with the rapid development of the economy,some problems have gradually emerged,and the irrational industrial structure is a prominent point.The logistics industry has a leading and pillar role in the development of modem social economy.It plays an important role in promoting the upgrading and rationalization of industrial structure and has a significant impact on the rate of economic development.In addition to the logistics industry,the improvement of technological innovation capability also plays an important role in the optimization and upgrading of industrial structure.At present,most scholars only study the relationship between them,and rarely study the relationship between them.There is a two-way causal relationship between the development of the logistics industry and the improvement of technological innovation capabilities.The development of the log:istics industry may promote the improvement of technological innovation capabilities,thereby promoting the upgrading of industrial structure.Therefore,it is necessary to study the relationship between logistics industry development,technological innovation capability and industrial structure upgrading.This paper reviews and sorts out the relevant literatures on the relationship between logistics industry development,technological innovation and industrial structure,and expounds the problems to be studied in this paper and the innovations of the thesis.Then the relevant economics theory is used to analyze the impact of the development of logistics industry and the improvement of technological innovation ability on the upgrading of industrial structure,and the effect of the development of logistics industry on the improvement of technological innovation capability.The arguments of this paper are further verified by mathematical model.Subsequently,this paper uses the fixed effect model to conduct empirical research on the relationship between logistics industry development,technological innovation and industrial structure.In the empirical study,this paper constructs a fixed-effects model,using 15 years of balanced panel data from 31 provinces in China to study the relationship between logistics industry development,technological innovation capability and industrial structure upgrading.And after the robustness test and endogeneity test,the empirical results were found to be basically consistent with the research hypotheses.Finally,it is tested whether the development of the logistics industry has a mediating effect and a mediating effect on the upgrading of the industrial structure.According to the empirical regression results,the paper draws the following conclusions:The development of logistics industry and technological innovation ability can promote the upgrading of industrial structure,while the development of logistics industry has a mediating effect on industrial structure,but it is mainly a direct effect.Finally,based on the results of theoretical analysis and empirical tests,the corresponding policy recommendations are put forward:China should continue to support the development of the logistics industry and maximize its role in promoting the industrial structure.At the same time,increase investment in the technology industry,strengthen the construction of scientific and technological talents,improve the ability of technological innovation,and promote the upgrading of industrial structure.The innovation of this paper is to put the development of logistics industry,technological innovation and industrial structure into a framework,and use technology innovation ability as an intermediary variable to analyze the impact of logistics industry development and technological innovation on industrial structure upgrading through empirical analysis.And whether there is a mediating effect between the two.Moreover,the paper also constructs a mathematical model to further verify the promotion of the logistics industry development and technological innovation ability to the industrial structure upgrade,and enhance the credibility of the conclusion of this paper. |
