| The urban spatial structure is the reflection of the social and economic activity on the urban spatial. At the background of planned economy, the spatial is the vehicle and container of economic activity, social activity and person behavior. Its economic value is small. But in the system of market economy, the spatial has more intension and more important signification. It becomes a resource from which the economy body gets economy profit. The evolution of urban spatial structure is not any longer closed and singular mode that is only leaded by the control government, but appears obvious spatial reconstruction because of the institution changing. So the methods of traditional or pure economics, the urban geography and the urban economics are not absolutely suit for the spatial structure investigation. The institution economics becomes the important key of explaining the China urban spatial structure evolution.Industry is the leading sector of the national economy. Industrial growth has very important influence on the economic growth for country, region and urban. Industrial allocation is crucial for economic and social development. The institution change conduces the changes of the industrial product structure and location choice essential. In our country, the influence on urban industrial spatial structure by institution change is more typical and representative. So analyze the institution change is better for taking investigation on industry spatial structure and optimizing it than analyze residential spatial structure and commercial spatial structure.Firstly, this passage analyzes the institution factors that influence the urban industry spatial structure. This part analyzes our country's land institutional change from the method of land allocation, the mode of land property right and land market, and analyzes the public ownership reform from the ownership transfer, intra-management of company, and investigates the process of regional government managing regional economy from hypostasis position to independence position, and then concludes the root reason of non-public company's development and other institution changes.Then, this passage contrasts the economic body and its activity before and after institution changing, discussing from government and company. Following the Jason and Muslin product model, we investigate the change of internal and external rules, the establishment of land market operating mechanism, and the reform of internal governable mechanisms of state-owned enterprises. Then these factors cause the change of behavior pattern of public ownership and non-public ownership enterprise. Therefore, new non-public ownership enterprise and state-owned enterprises, which locate in the inner cities, move to the suburbs or the marginal city. We analyze decentralize and localize political authority from a central authority. It causes emerge of the industrial district and industrial development zone. So the industry spatial structure rebuilt.This passage introduces the Jinan city's urban industry spatial structure evolution as an example. We analyze the Jinan city's evolution course of spatial form. 1978 is used as a interface to study the features of Jinan city's spatial structure under planned economy period and economy transition period. And this passage introduces the industry area information in 1977 and 2005 to analyze the spatial structure changes of Jinan city, and then concludes the evolution model of Jinan city's industry spatial structure.Finally, based on the existing issue, this passage brings up the suggestions and countermeasures of accelerating institution reform and optimizing urban industry spatial structure. |
