| 摘 要： | 对于人多地少的中国而言,抑制当前城市化发展中出现的城市用地无序扩张现象,是一个重要且急迫的问题,而政策调控的前提条件则是理清城市用地扩张的驱动机制。通过对中国不同规模、不同行政级别城市用地扩张驱动机制的差异性进行分析,本文尝试着构建了一个更为细化的城市用地扩张理论框架,并利用2001-2011年中国243个城市的面板数据进行了固定效应模型检验,证明了本文所提出的工作假说。研究结果表明：①人口对城市扩张的作用随城市规模升高而递减。小城市用地受到三产业发展推动,而中等城市、特大城市用地则受到二产业发展的推动,其中特大城市受到二产发展更强的影响。大、特大城市较之中小城市,用地扩张受到政府财政支出更强的推动。政府招商引资行为仅对大城市用地扩张有促进作用,对于小、特大城市反而有抑制作用。土地财政的增加也会显著推动城市用地扩张;②相比于地级市,高行政级别城市的政府财政支出对其用地扩张有着更强影响。由于高行政级别城市中政府干预能力较强,土地资源存在错配的问题,二产业仍然是高级别城市、特别是特大城市中用地扩张的强影响力因素,这则有悖于城市发展中产业结构变化的一般趋势。在证明了城市间存在异质性之后,本文建议,相应的城市用地调控政策应该意识到城市间的异质性,有针对性地给出治理政策。 |

| Abstract: | Considering the basic characteristics of China can be described as too many people and too little land. So the phenomena that urban sprawl in the urbanization should be taken as a seriously problem and be solved as soon as possible. Before we try to regulate the urban sprawl ,we must make clear the driving-force mechanism of the urban growth. In this paper,from the view of urban size and urban hierarchy,we attempt to form a more detailed theoretical framework of urban expansion driving force. Furthermore,we used data from 2001 to 2011 for 243 cities in China and a fixed effects model and found that the pushing effect of population on urban expansion decreases when urban size increases. Tertiary industries are pushing small city expansion and secondary industries are pushing medium city and mega city expansion. Government expenditure plays a more significant role in urban expansion in large cities and mega cities than small and medium cities, The government’s behavior regarding inviting investment can push urban expansion in large cities;however,it can reduce urban expansion in small and mega cities. Land finance can push land expansion. Compared with prefecture level cities,governments in high status cities can promote urban expansion more effectively by using the government expenditure. Because of policy bias,the governments of the high status cities have more power to influence urban expansion and the existence of the misapplication of resources,secondary industries are still a powerful factor which can influencing urban expansion in high status cities, especially in mega cities. After the existence of heterogeneity between cities is shown,then we can suggest that the policy about urban expansion need to consider differences between the cities. |
