Urbanization, perhaps, is the only route to realize modernization. It is a powerful support for coordinating regional development among different regions, an important way to expand domestic demand and promote industrial upgrading, and also a principal method for solving the issue of agriculture, rural areas and famers. Since the reforming and opening up, China's Urbanization has made great achievements, and urban population increased from172million people in1978to731million people in2013, and urbanization rate increased from17.92%to53.73%, which has reached the average level of the world. Urban space is the material carrier of urbanization development and spatial carrier of social economic activities. There are many factors which may hinder the flow of urban element and the development of urbanization, for instance, homogenous urban spatial morphology, high urban spatial density, unreasonable urban spatial structure. On the one hand, economic globalization and regionalization is pushed forward, which promote the optimal allocation of resources and elements on a global scale. Usually under the condition of spatial constraint, industrial investment and transfer taking multi-national corporations as the main body chooses the best location in the global scope, which generally is realized by the assembling of upstream&downstream and related industries in urban and changes with the variation of production element, government policy, and economic environment and culture values. On the other hand, the government and the state attaches great importance to the role played by the development of urbanization with China's characteristics, and the party's16th congress puts forward the policy'walk a special road of urbanization with China's characteristics'; the17th congress further supplements the policy as' According to the rule of coordinated rural planning, reasonable layout, saving land, fully functional urban, and small to big, coordinated development of cities and small towns should be promoted; the18th congress puts forward the concept of 'new urbanization' and further proposes 'urbanization is the core power of China's economic growth in the future'; The Third Plenary Session of the11th Central Committee proposes a pattern of modernization, which advocates complete space development of domestic land and harmonious development of man and nature, a new relationship, which recommends nursing the agriculture by the industry, urban areas helping rural areas, a model of mutualism between industry and agriculture and integration of urban and rural areas, and a system mechanism, which promotes urbanization development. In2013, the Central Working Conference about Nationality Affairs pointed that we expected to insist humanism and human-centered urbanization, to optimize layout, to construct scientifically reasonable layout according to the capacity of resources and environment, to promote rational division and balanced development between small town and medium-sized&large city, to generate reasonable structure of production, life and ecological space according to the overall requirements to promote space efficiency of production space, habitable living space, scenery ecological space. Obviously, optimization issue of urban space has been attached great importance by the party and state, the structural layout and optimization adjustment of urban space provide basis and guarantee for improving the quality of urbanization, promoting the relationship between rural and urban areas and coordinating the development of small town and large city.This thesis takes Sichuan province as the research sample mainly because that Sichuan is a significant' bridgehead' to promote western development, an important' locomotive' to promote economic growth, an important'accelerator'of economic development in western regions, the base of to supply national energy and security, and the most important ecological barrier to protect the upper reaches of the Yangtze river. As Sichuan is an important economic, industrial, military, agricultural, ecological and cultural province in China, scientific layout and optimal adjustment to its urban structure is helpful to explore new urbanization path for western areas in China so as to promote a new round of large-scale development of the western region. At the same time, it also provides policy reference for Sichuan development which add new perspectives and ideas for coordinating regional development, and reference for the optimization of other regions' urbanization.This study mainly takes an overall target as the core and carries out the research from three levels, three clues, three tests and three mechanisms. Specifically speaking, this study starts from macro, meso and micro levels, and takes space density, space scale and space morphology as clues. Then, it concludes the realized layout of Sichuan urban layout, assessment results and significance of influential factors on urban structural through space gravity model, coordination function and spatial lag model. From the mechanisms of government role, market resource allocation and social coordination, it also solves and straightens out the obstacles of various institutional mechanisms to optimize space structure and finally realizes the overall goal which takes large city as the core, regional center city as the support, and small towns as the backbone. This dissertation is organized as follows:This first part is the theoretical part and mainly studies on the definition of urban space and its concepts, some basic theory, evaluation method on urban space optimization and space mechanism The first chapter makes a detailed description of research background, significance and the scope of urban structure optimization, and makes clear the main innovation and deficiencies of this research through reorganizing both domestic and foreign research. The second chapter analyzes the basic theory of urban spatial structure, constructs a theoretical framework, clearly defines the concepts of urban spatial structure, urban spatial density, urban space function and urban morphology and further analyzes the enlightenment of the theory of urban spatial structure under the guidance of the basic theories. The third chapter discusses the evaluation system and connotation of urban spatial structure, demonstrates the overall target taking basic theory for support and guidance, analyzes urban structure optimization and makes theoretical preparation for the following research. The fourth chapter studies on the mechanism of urban spatial structure optimization, clarifies the connotation and elements, and lays a theoretical foundation for the analysis of the optimization mechanism in Sichuan through comprehensive analysis of government role, market allocation mechanism and private participation.The second part is the empirical study, including historical evolution of urban spatial structure and realistic layout, three tests on the factors and problems of urban spatial structure, optimization mechanism of Sichuan urban spatial structure and the overall train of thought, macro path and the current policy. The fifth chapter studies mainly the historical evolution of urban spatial structure and realistic layout and focuses on the analysis of Sichuan's structure optimization in each stage and the characteristics of structure layout. The sixth chapter is the core of empirical part, and it discusses the realistic layout of urban spatial structure through the space gravity model, determines the specific stages of urban spatial structure in Sichuan through efficiency function and coordination function, and analyzes the index system of optimization through SLM model. Finally, it analyzes the problems faced by Sichuan's urban spatial structure optimization based on previous empirical study.The seventh chapter focuses on optimization mechanism of urban spatial structure in Sichuan, clarifies the obstacle among the role of government, market allocation mechanism and private participation and then analyzes the problems of urban space optimization in Sichuan. The eighth chapter is the suggestion part of this research. It gives clearly general idea of urban space optimization through in-depth analysis of the three mechanism and related problems, including the optimization principles, contents and focus and try to explore the macroscopic path of urban spatial optimization and proposes corresponding countermeasures and suggestions on the most urgent problems. The ninth chapter is the conclusion part and it draws the conclusion of this study and corresponding research prospects through the summary of the whole thesis.This thesis focuses on the overall objective of urban spatial optimization in Sichuan, mainly concentrates the efforts on the advancement of spatial density, spatial scale and spatial structure and gives new clues on the following aspects: First, this thesis extends the study on urban space optimization from single city to the scope of whole province, discusses urban spatial structure and scale and studies on the system function and optimization problems of urban space. Second, this thesis builds up the evaluation index system of urban spatial optimization and concludes the stage of Sichuan's urban space optimization. Third, this thesis clarifies the mechanism among the role of government, market resource allocation and social public coordination to promote urban space optimization in Sichuan and discusses in detail how to promote urban space optimization. Fourth, this thesis considers the influence of space on urban spatial structure in Sichuan and improves the model's credibility through making full use of space econometric analysis and adding the space weight matrix to the model. Therefore, this thesis can provide new ideas and perspectives for further promoting new urbanization construction, provide policy reference for implementing the 'three strategy' and provide useful reference for the urban space optimization in other regions.
