Research On The Industrial Structure Convergence Of Five Cities In Hexi Corridor Of Gansu Province

Gansu Province has an important strategic position in the Silk Road Economic Zone.The development of node cities in Gansu is closely related to the construction of the Silk Road Economic Zone and the Gansu golden section.The research on the industrial structure of node cities is of great significance in the construction of the Silk Road Economic zone.Firstly,this paper defines the basic concepts of industry,industrial structure and industrial structure,expounds the evolution theory of Petty Clark's law and other related industrial structure,and then gives a comprehensive description of the economic belt of the Silk Road,the golden section of Gansu and the convergence of industrial structure.Secondly,the paper summarizes the social and economic situation of the node cities in Gansu,and selects the five cities in Hexi Corridor as the node of Gansu city industrial structure convergence of the research object,because of geography,history,natural resources and so on.Thirdly,based on the development yearbook of Gansu province2012-2016,the paper calculates the structure similarity coefficient between the three industries,the primary industry,the second industry,the industry and the third industry in the Hexi five cities,to determine whether there is an industrial structure convergence in the five cities in Hexi Corridor.Finally,based on the data of five cities and Gansu province from 2011 to 2015,using the shift share analysis method,the paper makes dynamic analysis about the industrial structure of the three industries,the primary industry,the second industry and the third industry,and then according to the similarity coefficient of industrial structure,based on the components and total deviation,the total growth,evaluates and analysises whether the convergence of industrial structure between the five cities is reasonable.Finally drawing a conclusion,in the regional economy of Hexi five cities,the convergence of industrial structure between Jiayuguan,Jinchang,Jiuquan and other cities in Hexi is undesirable.And most of this undesirable result is due to the lack of competitive industries.This paper provides a reference for the economic development of the Gansu section of the Silk Road Economic Zone,and provides some ideas for the adjustment of the industrial structure of the five cities in the Hexi Corridor.
