Chongqing City, The Combined Effect Of Regional Spatial Interactions In Empirical Research

Regional spatial structure is not only the main content of economic geography, urban geography ,but also the aspect of exploring the regional economic integration and promote coordinated development of regional economy which must be identified. Especially in China's urbanization and industrialization process, population movement is speeding up, logistics trades is frequency, capital flows accelerated inter-regional linkages to rely on physical geography gradually weakening, the ties increasingly are with the non-material and substances morphological closely in economic, social contact, cultural. In order to speed up regional development, promote win-win cooperation and so on played an increasingly important role, and gradually formed a diversified regional spatial landscape structure. This is not only a region of space the result of mutual influence, but also for the future direction of regional development, regional cooperation, such as object selection of regional policy to provide essential reference.In this paper, based mainly on regional spatial structure theory, the introduction of creative urban agglomeration effects of the space under the influence of the interaction model, at the same time analyzing the mechanism of interaction between regional spatial characteristics, from the city, transport, industry a comprehensive analysis of different angles, a prerequisite for spatial interaction and influencing factors, combined with the Chongqing Municipal regional spatial structure is characterized by qualitative and quantitative testing. Study found that transportation accessibility and regional space formed by the interaction strength of regional spatial structure model of the whole show very high similarity to Chongqing Municipality as an example, in the urban domain, to different cities as the center the size of the three major regional formed between the geographical space showing a circle-style regional spatial structure, and compare the two significant axes of space transportation. At the same time, for the dual economic structure significantly less developed regions, urban scale has become the regional agglomeration effects of radiation an important factor in the spread of ability, and its internal inter-regional industrial structure is not complementary to play an important role.
