Research On The Industrial Isomorphism Of The Three Core Cities Of The Yangtze River Economic Belt

Based on the background of the Yangtze River Economic Belt strategy,select three city which has an important position: Shanghai,Wuhan,Chongqing as the research object,through the analysis of the industrial structure similarity analysis,dynamic shift share analysis and exploration of industrial location entropy within the industry the industrial isomorphism problem and the city competitive advantage.In addition through empirical analysis on three factors of city industrial structure according to the results of empirical analysis of Shanghai,Wuhan,Chongqing,try to put forward the industrial structure of different development path,to avoid the phenomenon of industrial isomorphism,optimize industrial structure,promote regional economic quality and efficiency upgrades.This paper first defines the relevant concepts of the Yangtze River economic belt,industrial isomorphism,leading industries and pillar industries,and green development,and combs and studies the related theories of industrial structure evolution theory and regional division of labor theory.Secondly,in the real economy,the present situation of the industrial structure and overall grasp of the comparative analysis,empirical analysis of Shanghai,Wuhan,Chongqing three city industrial structure convergence degree,the empirical results show that there is a serious problem of industrial structure in Shanghai,Wuhan,Chongqing three city,which was within the second industry isomorphism.In order to determine whether the three inter city industrial isomorphism problem is homogeneous,and choose 2007-2015 years 33 industry data location entropy estimates,found that three city leading industries are more concentrated in the modern manufacturing industry,namely the three inter city industrial isomorphism problems with qualitative phenomenon,which is the leading cause of second the convergence of industrial structure.Then the dynamic shift share analysis of the three cities' 2007-2016 years' industrial structure development shows that three cities have their respective structural advantages and competitive advantages.In addition,according to the previous empirical research results from the economic efficiency,ecological efficiency and regional competitiveness of the three aspects of the industrial isomorphism to analyze the harm.Thirdly,the panel model is applied to analyze the main factors that influence the industrial isomorphism in three cities of Shanghai,Wuhan and Chongqing.The conclusion is that the expansion of resource endowment difference and the difference of science and technology will inhibit the convergence of three cities' industrial structure to some extent.Finally,in-depth analysis ofthe research conclusion,and put forward to promote the Yangtze River Economic Belt strategy implementation process,to build in Shanghai,Wuhan,Chongqing as the core of Ecological Protection Alliance and to construct a new competitive cooperative relationship and clarify each city has a comparative advantage in industry,countermeasures and suggestions to promote the development of regional economy and regional growth pole create.
