Under The Background Of Rapid Urbanization In Xi 'an High-tech Zone Economic Spatial Structure Evolution Research

Urban geography has been the study of urban spatial structure, the evolution of its internal mechanism as the core of the urban space. As human entered the urbanization and industrialization era, the urban spatial structure is restructuring, decomposing and evolving unceasingly, and it reflects in the city essential factors and so on society, economy, population in the spatial combination and the evolution.Since the1990s,most cities in China have entered the fast urbanized development time. The one hand, the GDP of the city is growing fast. On the other hand, the city space fast is also expanding. Expansion of the urban space, urban land use changes in the structure of urban spatial structure has led to the reorganization, urban social structure, the structure of the economy, and change. As having significant and action in Xian’s economic construction and urban construction——Hi-tech zone, with rapid growth of contemporary urbanization, its industry spatial structure changed quite a bit. Research on its spatial structure is better suited for knowing about the city of Xi’an development and trend. Due to the leading petrochemical of Xi’an, it provides reference about studying other western cities’population and industry changes.The paper consists of six parts as follows:Chapter1introduces the purpose、 significance、research methods and writing ideas of this thesis. Chapter2,first carries on the discrimination to the region economical spatial structure correlation concept. In this foundation, discussion correlation region economical spatial structure evolution pattern and mechanism. Chapter3mainly carries on the determination to the Xi’an urbanization and the industrialization stage, the analysis of the industrial structure of Xi’an, and evolution of macroeconomic analysis of the Xi’an Economic Space. Chapter4,analyzes of the background、 development status and the feature of the Xi’an High-tech Zone Development, analyzes of high-tech zone economic spatial structure and the evolution process are included. Chapter5has analyzed the dynamic mechanism which the urban economy spatial structure evolves, In the last chapter6,conclusion and the limitations and suggestions for further studies are included.The main research findings and perspectives of this paper are listed as follows: On the whole, Xi’an Hi-tech Zone spatial structures performance gathering momentum. The spatial structure of industry gather in the form of Parks. Its spatial changes are mostly the results of self-development of the region and the spread of Xi’an Center.Furthermore,because of multiple factors in the role, for example, the policy factor、geographic advantages、socio-economic development factor and large-scale construction project, population and industry are pulling together, which determine dynamic variations of Hi-tech Zone’s spatial structure.
