基于城市基礎(chǔ)部門模型的成都市規(guī)模研究
[Abstract]:Since the reform and opening up, all kinds of large, medium and small cities in China have developed rapidly, and the urbanization process has been accelerating. As the center of various economic and social factors, cities are the space carriers on which urban economic and social development depends. Since the reform and opening-up, China's urban scale development policy has undergone different adjustments. Under the macro-control of the national urban scale development policy, various localities should formulate the urban scale development war suitable for local urban development according to local conditions. The urban basic department model is an important theoretical model of urban economics. It can not only explain the growth of urban economy, but also explore the mechanism of urbanization and reveal the development law of urban scale. It can provide theoretical basis and practical method for each city to formulate its own urban scale development policy according to local conditions. On the basis of previous studies, this paper, from the perspective of the interaction between urban population size and urban basic sector industry, combined with the urban population and employment data of Chengdu in Sichuan Province in the past ten years, uses the basic sector model to explain the mechanism of the industrial development of basic sector in Chengdu on the development of urban scale, and combines the grey system. The system model predicts the development of urban scale in Chengdu in 2020. The first chapter is the introduction, which explains the background and theoretical and practical significance of the research on urban scale, and summarizes the research results and current situation of the relationship between urban scale and industrial development, urban scale prediction, and urban basic department model at home and abroad. The second chapter is the definition and theoretical analysis of urban scale research. The theoretical basis of urban scale research is elaborated emphatically: from the perspective of urbanization, Petty-Clark theory to explain the urban industrial development institute. The quantity of labor force that can be absorbed influences the future urban scale, which lays a theoretical foundation for the following discussion on the influence of basic sector industries on the urban scale. Based on the theory of regional division of labor and the basic theory of export, this paper explains that each city has comparative advantages, undertakes different division of labor, forms different basic departments and plays different roles in the size of the city. At the same time, the economic development of Chengdu has made remarkable achievements in recent years. The advantages of industry, construction, real estate and information industry are obvious. The basic department model of the city shows that the development of the city scale is closely related to the development of the basic department. Compared with the developed cities of Beijing and Guangzhou, the development of the tertiary industry in Chengdu is still lagging behind, the service industry level is not high, the proportion of employees in the tertiary industry is low, and there is still much room for development in absorbing labor force employment. Secondly, the location quotient method is used to distinguish the basic and non-basic sectors of Chengdu city. Thirdly, based on the derivation of the urban basic sector model, the coefficients of the basic sector are calculated, and the role of the development of basic sector industry in the development of urban scale is explained with data. Mechanisms, research shows that each additional employee in the basic sector will lead to an average increase of 0.18 employees in the supporting sector, 0.37 employees in the public service sector, and an average increase in the number of dependants due to the increase in employment of 1.14 people. Fourthly, the grey system model Verhulst is used to predict the number of employees in the basic sector of Chengdu by 2020. Based on the development of the basic sector industry, the number of employees in the supporting sector will increase by 6803,000, the number of employees in the public service sector will increase by 1406,000, the total number of employees will reach 6.0926,000, the number of people supported by the employees will reach 5.6328,000, and the total urban population will reach 1,725. The fifth chapter is the analysis and Countermeasure of the development trend of urban scale in Chengdu.According to the fourth chapter, it is predicted that the urban scale of Chengdu will reach about 11.7254 million by 2020.Compared with the new urbanization plan of Chengdu from 2015 to 2020, the urban basic departments of Chengdu will have a smaller population size to absorb in the future, if they want to reach the city of Chengdu. The goal of the development plan is to continue to support the development of superior industries in basic departments, promote the integration of population and industrial agglomeration, enhance the absorptive capacity of industrial employment, the carrying capacity of urban economic population and the city's human charm.
