Research On Coordinated Development Of Urban Evolution And Industrial Optimization In Jingjinji Urban Agglomeration

The transformation of the economy and the society is the most prominently nationalcondition in the new century in China. The systems，economy, society and other aspectswill happen the significant changes. Particularly, the space reconstruction will be theimportant change based on the variables of the distance, density and segmentation. The newless-regional body, which is caused by the integration of the regional economy, the rapidagglomeration of the production factors, and the greater refinement of the specializationdivision of labor in the production, is emerging and continues to develop. The urbanagglomerations focused on several large cities, which make a distinction between theimportant and the lesser one, and clearly divide the labor and co-evolve, is increasinglybecoming the main form in the development of the regional economy in China. TheBeijing-Tianjin-Hebei Urban Agglomeration has already entered the rapid developmentstage. It is the important features and objective requirements of the regional development inthe new era in China to promote the process of urbanization by accelerating the urbandevelopment and reconstructing the urban space system, and to enhance thecompetitiveness of the region and guide the coordinative development of the region bypromoting the development of the industrial structure.The development trajectory of the typical urban agglomeration at home and abroad hasalso been proved that any development of the region has its inherent laws, and these laws atthe industry level meet the evolution of the industrial development. In a certaindevelopment period or several development periods, the region may develop fast because ofthe promotion of the industry. But a fast-growing city will not indefinitely maintain itsmomentum of the rapid development. It will slow down the speed, and be faster or slower,again and again, and ultimately replaced by a new growth. In this process, the citygradually evolves and develops to a full-featured high end, and the industry is graduallyoptimized. In the interactive coordination, both of them lead the development of the wholeregion, namely, the urban agglomeration economy relies on the "two-wheeled drive " fromthe industrial optimization and the urban evolution to promote the sustainable andcoordinated development. It will play a significant role in the theory and reality to in-depthresearch the interaction between the city evolution of the Urban Agglomeration and theevolution of the industrial structure in China for accelerating the space development,especially for the coordinative development of Beijing-Tianjin-Hebei UrbanAgglomeration.The research of this paper is designed from two points. They are the normativeanalysis and the empirical research, which are confirmed by each other, and form anorganic whole with the identical logic and the strict structure. The main innovative work as follows:The theoretical framework of the industrial optimization and the urban evolutionin urban agglomerations is formed. Through looking over the literatures of both insideand outside China, the research on the industrial optimization and the urban evolution inurban agglomerations has not been found in the rare research about the urban evolution.Based on the results of previous studies, this paper defines the concept of the industrialoptimization and the urban evolution, and sets up the theory model of the industryoptimization and the urban evolution in urban agglomerations, that is: in the space of urbanagglomerations, the industrial optimization is the power source of urban evolution and theurban evolution is the supportive guarantee of the industrial optimization. Furthermore, thispaper analyses its functional mechanism, including the specialization division of labor andthe external economy, the economy of scale and the economy of scope, the process of theindustrialization and the urbanization, the process of the economic globalization and theregional economic integration, the system arrangements and government policies and etc..The spatial extent of Beijing-Tianjin-Hebei Urban Agglomeration is defined byusing the Economic Relation Intensity Model and Urban Stream Model. The researchon Beijing-Tianjin-Hebei Urban Agglomeration is rare in the literature about the spatialrelation. This paper conducts the empirical research about the space relationship ofBeijing-Tianjin-Hebei Urban Agglomeration by using the Economic Relation IntensityModel and Urban Stream Model from the dimension of the region and the industry. Thispaper takes the definition of famous scholars on urban agglomerations as the criterion,defines the space range of Beijing-Tianjin-Hebei Urban Agglomeration as “2+8”, that isBeijing, Tianjin, Tangshan, Qinhuangdao, Chengde, Zhangjiakou, Baoding, Langfang,Shijiazhuang and Cangzhou.The empirical research on the industry optimization and the urban evolution ofBeijing-Tianjin-Hebei Urban Agglomeration is carried out by using the SpatialInteraction Models. The current study about space interaction is very rare. In this paper,the industry optimization and the urban evolution are studied deeply based on theSpace-sectional Data Model about Space interaction. The result shows that in thedevelopment of the economy in Beijing-Tianjin-Hebei Urban Agglomeration, except of HRand the urban evolution which have strong negative effects, others all promote thedevelopment. Of these, the physical capital and economic factors of non-stated-owned areprominent, next comes the industry optimization and then FDI and R&D. The stimulationeffect of HR and the urban evolution does not fully realize. In the development of theeconomy in Beijing-Tianjin-Hebei Urban Agglomeration, the industry optimization and theurban evolution play different roles, but do not develop harmoniously.The space of Beijing-Tianjin-Hebei Urban Agglomeration is reshaped by usingArc GIS. This paper analyses the industry optimization and the urban evolution by using Arc GIS, and defines the space structure of Beijing-Tianjin-Hebei Urban Agglomeration asthe structure of the circle industry with the multi-pole of the growth and the multi-axis ofthe development. And then the space of Beijing-Tianjin-Hebei Urban Agglomeration isreshaped in this paper as following: The comprehensive transport network-a Network withThree Hubs, the space distance-One Hour Metropolitan Region, and the town layout-theTown Complex with Different Functions. The space of the industry is reshaped to themulti-pole of growth, the primary and the secondary axis of development, the industry withcircle layout and etc..
