Study On Industrial Agglomeration Evolution And Functional Division Of China's Cities From The Perspective Of Space

The industrial agglomeration and the city has the good interaction relations,the city plays the carrier pole of the industrial agglomeration activity,the external effect and the scale effect of agglomeration promotes the city competitiveness.The industrial agglomeration has become an important method of the local government to promote the economic growth.Moreover,with the development of industrialization process,the urban industrial structure has the trend from the Industry leading to the Services.the Services is also showing obvious industrial agglomeration feature in the city.In addition,with the continuous expansion and extension of industrial value chains,the urban function also presents a trend of specialized division,and the industrial agglomeration is the spatial organization of division.Therefore,this thesis focuses on the industrial agglomeration evolution and functional division of China's cities from the perspective of space,through combing the mechanism of urban functional divisions in China under the evolution of industrial agglomeration,makes it clear that the emphases of industrial agglomeration in different grades and scale cities,uses city-level data to empirically test the practical effects of different industrial agglomerations on economic growth,indicates the direction of the rapid development of China's urban economy and the rational distribution of regional industries.On the theoretical level,through expanding the "core-edge" model of the new economic geography,the paper explains the market mechanism of the agglomeration evolvement of different factor intensive industries under the dynamic selection of enterprises.At the same time,the paper defines China's urban hierarchy and divides the type of industry,considers the role of government factors,constructs and explains the mechanism of industrial agglomeration evolution and functional space division in China's cities under the guidance of the market and government.The study finds,under the spontaneous role of market mechanisms and the reasonable guidance of government,central cities represented by municipalities,sub-provincial cities,and provincial capitals in China will focus on the agglomeration of capital-intensive service industries,general cities will focus on the layout of labor-intensive manufacturing industries.The functional space division pattern of "central city service and general city production" will be formed in the spatial scope.In the empirical test section,based on panel data of China eastern city,this paper examines the evolution trend of manufacturing and services agglomeration in central cities and general cities,verifies the inner mechanism of urban industrial agglomeration and functional division in the theoretical part.At the same time,the services is further subdivided into high-end,low-end producer services and consumer services,obtains a more detailed functional division between cities.Secondly,based on the panel regression model of industrial agglomeration and economic growth,this paper examines the agglomeration effect of various types of industries in different grades of cities.Finally,this paper compares the functional spatial division of the two typical provincial area urban agglomeration,the Pearl River Delta and the Shandong Peninsula,summarizes the factors of the functional spatial division of urban agglomeration.Several conclusions are drawn as follows:(1)From the perspective of space,the phenomenon of urban functional division in China is obvious.The services agglomeration scale of central cities is strengthened,manufacturing is gradually spreading and diverting,the service function of the city has been further strengthened.The general city only forms the manufacturing agglomeration scale and the urban production function is obvious.(2)The economic growth effect of industrial agglomeration has the heterogeneity of industry and city scale.The central city producer services,especially the high-end producer services agglomeration's economic growth effect is very significant,because of unreasonable layout,the collaborative economic growth effect between consumer services and other industries has not been brought into play.Manufacturing agglomeration of the general city has promoted the urban economy growth.After joining the city economy scale threshold,in the economy more developed general city,the low-end producer services and the consumer services which is closely related to manufacturing industry,also shows positive economic effect.(3)The different level of transportation,informatization and marketization have caused the difference of regional transaction e:fficiency,which affects the function space division effect of urban agglomeration.Finally,according to the theoretical and empirical research,this paper puts forward some policy suggestions for the development of urban industry and economy:Firstly,taking a spatial perspective on the development of urban industries,paying attention to the division of functions among cities,guiding the dislocation development of industries,to realize the maximization of the industrial agglomeration effect.Secondly,playing the role of government properly,selectively using industrial policies to support industrial agglomerative development that suits the city's own economic development under guidance of the market mechanism.Then,integrating the consumer services into urban industrial planning,promoting the development of industrial synergy.Finally,accelerating the construction of regional transportation,information and communication networks,creating a sound market environment and a relaxed policy environment,and promoting the urban functional division in China.
