Diffidence and Influencing Factors of Urban Land Development Intensity Across 222 Cities in China
城市土地开发强度差异及影响因素研究——基于222个地级及以上城市面板数据

The development intensity of urban land is an important indicator of the level of sustainable land utilization of a city. A modest development intensity for urban land benefits both ecological protection and living spaces. We selected 222 municipal cities in China and measured the development intensity of urban land as the proportion of construction land to total land from 1997 to 2009. Agglomeration features for the development intensity of urban land were higher in the Yangtze River Delta,Pearl River Delta, and Beijing-Baoding-Shijiazhuang-Xingtai- Zheng zhou-Luoyang area,and lower in western China. Development intensity is higher in the capital city of a province, and there is insignificant difference between and within provinces. Development intensity of urban land increases with the size of cities. There was a significant positive correlation between economic growth,urbanization, industrial structure and the development intensity of urban land. Land planning policy had no significant negative effect on the development intensity of urban land in the national model. It it is necessary to adopt differential measures to control development intensity. In order to maintain development intensity of urban land at a reasonable level, measures such as changing economic growth patterns, land management policies and urban planning,promoting urbanization and urban industry distribution in reasonable ways must be implemented.
