The Study Of The Influence Of Beijing Population Agglomeration On Urban Economic Development

With the deepening of reform and opening up and the enhancing development of market economy, the industrial structure layout of Beijing is adjusted constantly and the process of urbanization is improved fast. Because of that, the population movement in Beijing is quite active and the problem that massive people gathering in the city is becoming more and more serious. The large floating population has a great impact on the Beijing’s economic development. In recent years, the population of Beijing is increasing rapidly. On one hand, a large number of people come to Beijing and on the other hand, the natural birth rate of the city is increasing. The floating population makes the central area facing great pressure. Although they bring infinite vitality and rich human resources to the city, a series of problems relating to the economic development and social administration come along.On the basic of theories, this paper defines the concept of population agglomeration and the economic development. And taking Beijing for example, this paper analyses the impact that alien population agglomeration has on Beijing’s economic development from the aspects of economic growth, industrial structure and resource environment. This paper uses EG index and JJD index to measure the population agglomeration in16districts and counties of Beijing. According to the agglomeration level, this paper divides the districts and counties into three areas---the dense area, the mean area and the sparse area. The paper takes advantage of population density function model to measure the spatial distribution and growth trend of population density. The results show that population growth rate in dense areas is higher than that in sparse areas. Finally, based on the datum from2004to2013, the paper built a panel data model to study how the immigrants influence the economic development in Beijing. The result is that the optimum population promotes economic growth to the hilt; beyond the optimum population is quite the opposite.At last, the paper puts forward some feasible advice to reasonably evacuate the immigrants and to further promote the development of the economy. Firstly, through the industry transfer drive the population transfer; secondly, strengthen the population average area cohesion, relief of the city population pressure; finally, make environmental legislation, clean technology and public participation with an organic whole, through the comprehensive measures to solve urban environmental problems.
