Empirical Analysis Of Influence Factors Of Urban Land Scale In The Area Of Yangtze River Delta

With the developing of the urban economy and the increasing of the urban population, it is inevitable for the urban land scale to expand gradually. There are many factors which affect the expanse of the urban land scale, well, how does each factor affect the urban land scale? Study on the influence of each factor on the expanse of the urban land scale is helpful to control the disordered expanse of the urban land scale on base and increase the use efficiency of urban land.This paper put several factors into a system, because this is helpful for completeness of analysis; use the panel data model to analyze the effect of each factor on the urban land scale from crosswise and longitudinal two aspects empirically. Because our country's economic institution reform is top-down, during the process of development of urban economy, government's function is very obvious, the expanse of the urban land scale is a market economy process incompletely. The empirical analysis in this paper has confirmed this viewpoint. This paper believed that, The non-market factor play a remarkable role in the process of expanse of urban land scale; The expanse of population scale causes the urban land scale to expanse directly; the optimization of urban industrial structure is advantageous to the intensive use of urban land; The government's effect on the expanse of the urban land scale is very obvious; The improvement of urban virescence is advantageous to the effective expanse of urban land scale; uses the scale expansion; the function of some indirect influence factor is not obvious, indicated that the expanse of urban land scale is at the initial stage, the function of market mechanism does not display fully.To the question of expanse of urban land scale in Chine, the city government's influence is not to be eliminated possibly in a short time, but we may transform the way which the government affects, namely the government's influence on urban land scale should be supposed to take the market economy principle as the basis, to help the enterprise and the inhabitant realizes its utility maximization as it's goal. In order to achieve such goal, the author believed, the city government should: Cancels the hu-kou institution, realize population's reasonable flowing; Optimize industrial structure, intensive land utilization; transform government role, expand the market operation scope; strengthen the city ecology virescence construction, improve the urban environment quality; develop the city utility enterprise vigorously, promotes the inhabitant quality of life.In the process of expanse of urban land scale, all impellent forces may be converged to the market force or the government strength. In order to make the expanse of urban land scale to be ordered and reasonable, should expand the market strength as far as possible, weaken the government strength or transform the way of government strength.
