Research On The Central Triangle Urban Agglomeration Economic Contact

Urban agglomeration is a special form of economic organization,it is the result of combined action for agglomeration and diffusion effect.The central triangle urban agglomeration is gradually becoming the leader of fourth pole of economic growth in our country.To study economic contact of central triangle urban agglomeration,which impacts jiangxi,hubei,hunan provinces and even the national economy will grow at a faster pace,and it is beneficial to achieve the linkage development between cities of urban agglomeration,make urban agglomeration towards integration of development,which has its practical significance.In recent years,scholars' researched mainly concentrated in the three huge urban agglomerations,not or less involved in the central triangle urban agglomeration,and the central triangle urban agglomeration had a high number of cities,data query and data processing are complexity,many scholars or simplify the research object,or simplify the research method,which all can't achieve the goal of comprehensive study economic contact of central triangle urban agglomeration.In addition,many scholars did not link the economic contact intensity and economic growth of urban agglomeration,the research purpose is not clear,and lack of horizontal comparison,so it is short of practical significance.In order to promote economic growth of the central triangle urban agglomeration,this paper takes central triangle urban agglomeration as the research object,using many ways to empirical research of urban agglomeration economic contact,to explore the relationship of economic contact strength and economic growth,then put forward some proposals to promote the economic contact of the central triangle urban agglomeration.This thesis is divided into five parts.The first part is the introduction.Firstly,introduces the research background and writing significance of this paper;Secondly,on the basis of carding the research status on our country and abroad,then make a simply comment.After that,elaborated the paper research content and methods;Finally pointed out the innovation and deficiency in this paper.The second part expounds the basic theory of urban agglomeration economic contact.Firstly introduces the basic concept of urban agglomeration,to urban agglomeration under a definition;Secondly introduces the three basic theory of urban agglomeration economic contact,lay a foundation for the back of the empiricalanalysis;Finally introduces the urban agglomeration economic contact effects: division of labor and collaboration,agglomeration and diffusion.The third part is the analysis of present situation and the obstacles to central triangle urban agglomeration.Firstly,defines the central triangle urban agglomeration area;Secondly expounds the present situation of the urban agglomeration economic contact;Finally summarizes four reasons of the obstacles to urban agglomeration economic contact.The fourth part is the empirical research.First of all,using the intensity of urban flow model,through the location quotient,measures intensity of urban agglomeration economic contacts between cities;Secondly,to modify the traditional gravity model,through factor analysis,use "quality of cities" instead of the urban population scale,and with "time distance" replace the dual distance,measures intensity of urban agglomeration economic contacts between cities;Then,using the evenness index model,through calculating evenness index,to explore the intensity of urban agglomeration economic contacts.Three models are all concluded: wuhan urban agglomeration's economic contact strength is higher than the poyang lake urban agglomeration and changsha-zhuzhou-xiangtan urban agglomeration economic contact strength.Finally,using the intensity of urban flow measured as independent variables,corresponding gross domestic product(GDP)as the dependent variable,to investigate the relationship between the intensity of economic contact and economic growth,it is concluded that the intensity of economic contact and economic growth is highly related.The fifth part embarks from the empirical study results,to promote urban agglomeration economic growth as the main purpose,to solve the existing problems of the central triangle urban agglomeration as a starting point,give some recommendations to strengthen the economic contact of central triangle urban agglomeration.
