| Urbanization is not only an objective phenomenon in the process of social-economic development, but also the research focus of academic circles in recent years. As a national strategy, urbanization has great practical significance to China’s social-economic development and transformation. At the same time, various problems brought by rapid urbanization are gradually being taken seriously in the case of current system and mechanism have not been perfect. By grooming urbanization problems at home and abroad, it is not difficult to find that urbanization social cost problem has increasingly been concerned by academic circles, political circles and other social organizations. Moreover, understanding of the issues has been increasingly changed from sense to reason. In view of the domestic and international research on urbanization social cost is concentrated in the field of economics and sociology, with characteristics of theoretical hybrid, single method, regional diversity and weak guidance, the thesis would study the urbanization social cost from the perspective of multi-disciplinary integration based on virtualness-reality interaction, combining with the macro background of current urban-rural development and urbanization. Research methods include materialist dialectics and historical analysis, normative and empirical analysis, qualitative and quantitative analysis, dynamic and comparative analysis. Through the research, the paper reveals the internal mechanism of urbanization social cost in Chongqing such as the time-space background, development, expression forms, dynamic mechanism. Then, the thesis would assess social cost objectively and put forward the three-in-one social cost control model by using of establishing different forms of “social cost-space” models so as to provide suggestions and countermeasures for the government policy making, and promote more reasonable and orderly development of urbanization.Research shows that urbanization social cost is not only a simple economic problem, or a spacial problem, but a comprehensive social problem, with some certain rules. First, urbanization social cost is relative to the social benefit, which are two sides of a coin. There is no cost without benefit, and vice versa. Second, urbanization social cost can be divided into narrow sense and broad sense. The former is economic cost, and the latter is total cost, including economic cost and non-economic cost. Third, urbanization social cost has characteristics of objective reality, tiered heterogeneous, dynamic accumulation, accounting difficulty and far-reaching influence, and the influence of natural, economic, social and policy, influencing by natural, economic, social and policy. Forth, urbanization social cost of Chongqing has profound historical reasons, with different dominant factors and forms in each historical stage. At the present time, urbanization social cost is restricted both by national urbanization strategy and local development. Under the action of social structuring and deconstruction as well as ideal and reality, social changes and risk occur, meanwhile social cost becoming a reality. Fifth, social cost calculation and analysis show that, the total urbanization cost of Chongqing continues to rise more and more quickly with social and economic development. In terms of item cost, personal cost and public cost are both rising, but which ratio of total cost has experienced a wave of change. In terms of index cost, each individual cost continues to show an upward trend, but the growth of each cost is difference, which can be divided into four groups from high to low. In terms of cost structure. Regardless of total cost or item cost, the job cost and housing cost have been the highest in total cost, followed by the daily life cost. Because of absolute values of the three costs have been high, so the ratios have been higher. Sixth, research on relationship between urbanization social cost and spatial development shows that urbanization level and social cost are in positive quadratic curve relationship, meanwhile, urbanization size and social cost performance are in positive power function relationship. Urban land structure and social cost are not related, but different kinds of land are related to social cost, which play different roles in social cost growth. The most important role is municipal public utility land, followed by external traffic land, and then, public facilities land, followed by green land, road land, industrial land and residential land. Seventh, urbanization social cost has systemic characteristics, and therefore the regulation should be a three-in-one theoretical model, including target system, content system and security system. In order to define development ideas and objectives, develop content system which is based on model guidance and spatial optimization, put forward specific measures for urban-rural integration, and establish security system including early warning, system, humanism and sharing. It is hoped that the urbanization would develop healthily through the above measures. |
