Evaluation On The Market Integration And Study On The Integration Model Of Three Urban Agglomeration In The Yangtze River Economic Zone

Market integration is the prerequisite and basis for regional economic integration,as a new space organization form,the city cluster plays an increasingly important role in the promotion of regional economic development,any area who wants to obtain and maintain a competitive advantage need to thinking about the mechanism of regional integrated development.Now the Yangtze River economic zone has risen to the national strategy,the Yangtze River Delta(YRD),the Central Triangle Urban Agglomeration(CTUA)and the Chengdu-Chongqing Urban Agglomeration(CCUA)are concentrated by others.At the present stage,it is the key to find out the level of market integration,the kind of development characteristics and what problems are presented of the Three Urban Agglomeration in the Yangtze River Economic Zone.This paper introduces the connotation and mechanism of market integration.It is pointed out that the degree of inter-city linkages and government effectiveness are the influencing factors,the Product market integration and factor market integration are the performance characteristics of market integration.Then,based on this,the paper builds the evaluation system of market integration,leads in aggregative indicator by urban flow model and the price method,composite index by entropy method and coefficient of variation.The Projection Pursuit Classification Evaluation Model is used to analyze current situation of the market integration of the Three Urban Agglomeration during 2000-2014.The results show that:The level of market integration and the four major elements have formed the pattern:YRD-CTUA-CCUA.The YRD has entered the stage of integration and quality improvement,the CTUA is in the stage of rapid integration,the CCUA is in the start stage of market integration.The YRD is "four elements Synergy Drive",the CTUA is "single factor-driven",the CCUA is "two-factor driven".Finally,on the basis of analyzing the general pattern of urban agglomeration,according to the integration level,the change characteristic and the driving factor of the three city groups,analys the choice of market integration model,policy implications are given to promote the integrated development of the Three Urban Agglomeration in the Yangtze River Economic Zone.
