Mechanism Analysis And Quantitative Study On Interactive Coupling Of City Group's Ecological-economic System

With the accelerating process of urbanization,urban agglomeration has become the main space carrier of urbanization and the most dynamic and potential core region in the productivity development pattern of China today.But at the same time,the urban agglomeration is also a region where the contradiction between resource and environment pressure and social-economic development is very prominent.In order to solve the contradiction between the resource and environment and the social and economic development of the urban agglomeration,and to promote the healthy development of urbanization,it is necessary to discuss the coupling and coordination of ecological-economic system of urban agglomeration from the theory and practice.Based on system coupling theory,inter-species relationship theory,Ecological economy coordination theory,and sustainable development theory,this paper makes an in-depth study on the theory,method and practice of interactive coupling of city group's ecological-economic system.In theoretical research,the purpose of the paper is to reveal the mechanism of interaction between urban agglomeration ecological-economic system.To this end,the paper carried out the following work.firstly,this paper defines the connotation and essence of ecological-economic system' interactive coupling of city group;secondly,this paper analyzes and grasps the constitutive mechanism and characteristics of ecological-economic system of city group;thirdly,on this basis of the above,this paper dissects the coupling relationships of internal factors of city group's ecological-economic system,and these relationships are used as the basis of the coupling phase;then,the characteristics of each stage are analyzed from the aspects of entropy flow change,commonness and individuality;finally,the papers accordingly refines three typical regulatory modes to promote the system coupling.In the aspect of methodology research,the paper takes the theoretical analysis of the interactive coupling of city group's ecological-economic system as the basis.Therefore,the comprehensive measurement of city group's ecological-economic system index system was constructed.Then,the paper quantified the interactive coupling of city group's ecological-economic system.In other words,the comprehensive measurement model of development level and the quantification model of interactive coupling of city group's ecological-economic system are established.In the practical application,the paper selects the west side of the Straits as an example.Firstly,the development level of ecological-economic system and its subsystem of urban agglomerations on the the west side of the Straits are measured.Secondly,the paper analyzes the dynamic coupling process and speed of this system by quantitative model.At last,based on the empirical results,this paper puts forward some countermeasures to promote the development of the ecological-economic system of the urban agglomeration of the west side of the Straits from the aspects of the government,market,industry,society,science and technology,law and so on.
