A Study On Evolution Of Urban Agglomerations Spatial Organization Based On The Heterogeneity Of Spatial Division Of Labor

Human geography, economic geography, and political economics and history andalmost always thought the formation and development of city thanks to the socialdivision of labor and industry diversification, diversification is the inevitable result ofsocial division of labor and industries, from a deeper level, social productivitydevelopment is the fundamental motivation of urban emergence and prosperity, decidesthe social division of labor and industry gradually diversification, heterogeneity and thedivision of labor is just is the essence of social productivity, so it can be derived fromthe theory of logical relationship found the essence of the city and even the emergenceand development of urban agglomerations is characterized by heterogeneity, theemergence of the division of labor and the further deepening is characterized byheterogeneity on the space the spatial division of Labor. Labor as the most basicsubjective controllable factors of production, in the process of combined with otherfactors of production play a role of guidance and policy makers, from micro leveldetermines the evolution of urban spatial organization and optimization.This paper based on the political economics, new institutional economics andinternational economics structure socialist orientation, industrial, urban location theoryof the new international division of labor of three cognitive, a preliminary analysis ofurban agglomeration spatial organization division of labor heterogeneity spaceperspective. The perspective of the mainstream spatial organization related theories areoften limited to the macro level of spatial structure and the form analysis of theproblems of the spatial organization of space interaction, and ignore the heterogeneityof labor as a micro main body and micro power division of labor spatial heterogeneity.The heterogeneity labor division of space view angle to consider the space formationand the space effect of inner logic, based on the analysis of spatial organization problemcan more deeply reveal the evolution of the macro and micro dynamic trend. Secondly,in view of the Yangtze River delta urban agglomeration heterogeneity labor spatialdivision evolution of the spatial statistical analysis found that: after spatial heterogeneitylabor division of labor evolution due to the formation of the differences of all kinds ofindustry showed a larger difference between accumulation regularity and diffusioncharacteristics. Finally, according to the theory angle, and connecting with the YangtzeRiver delta urban agglomeration heterogeneity labor spatial division evolution of the preliminary conclusion of Yangtze River delta urban agglomeration spatial structureevolution to delve into systemic characteristics, mainly analyzed from two aspects: oneis the Yangtze river delta urban agglomeration scale structure, secondly, the Yangtzeriver delta urban agglomeration function. Scale structure of Yangtze river delta urbanagglomeration of descriptive statistics, statistical analysis and empirical descriptionfound that: on the one hand, the scale of the Yangtze river delta urban agglomerationdistribution presents the obvious first type distribution, large city scale developmentspeed obviously faster than the small and medium-sized cities, but the gap betweenthem decreases. On the other hand, the Yangtze River delta urban agglomeration spatialstructure gradually by the polar nuclei to multi-center network structure, the axis and thestructural shift, but still not mature, in the network of primary stage. From the angle ofindustrial spatial differentiation of urban agglomeration spatial organization groupevolution trend found that the whole Yangtze river delta urban agglomeration spatialheterogeneity labor division of labor pattern gradually due to the low levelconsciousness mainly in Shanghai, for nuclear core to higher and more complicatedstructure of peripheral to the core of the local as the center, peripheral secondary corefor the node of network space development. At the same time, the division ofheterogeneity labor space differentiation under the influence of industrial spatialstructure affect universal enhancement, random effects are weaken to some extent, thewhole Yangtze river delta urban agglomerations overall develop situation positive, localspatial spillover effect is obvious. Yangtze river delta urban agglomeration function highcontact strength with the city mainly concentrated in the area between administrativecenter and manufacturing more developed city, economic development level is low,even if the location near the messenger of region, the economic strength is stillrelatively low. Good with access letter makes the economic ties between the cities bythe conditionality of geographical space distance gradually decline, especially edge city.The growth degree of connectivity between core city and edge city is speeding up,urban agglomeration coordinated economic development level, regional economicnetwork was significantly enhanced.
