城市化与城市土地利用结构的相关研究

Correlation Study Between Urbanization and Urban Land Use Structure

城市化发展与城市土地利用结构变化存在相互影响。从城市化的核心内涵生产(就业)和生活(居住)两条路径出发,建立了城市化与城市土地利用结构之间的逻辑关联,并利用2000-2009年中国29个省际面板数据模型进行了实证检验。结果显示:从全国来看,生活用地比重与城市化发展呈现显著的正相关关系,生产用地比重与城市化发展呈现倒U型变化趋势。公共设施用地比重和市政公用设施用地比重与城市化的关系在各地区均表现为显著的正相关关系,且回归系数呈现自东向西逐渐减小的趋势。道路广场用地比重与城市化的关系在东部和西部呈现显著的正相关关系,且东部的系数明显大于西部,因此加强东部地区内的道路建设对提高整体城市化水平更为有效。对外交通用地比重与城市化之间的关系呈现自东向西的渐变趋势,在东部地区两者呈现显著性正相关关系,中部地区的正相关关系不明显,西部地区呈现负相关关系。可以通过调整城市土地利用结构来推进城市化发展。

There is an inter-effect between urbanization and urban land use structure change. In order to show the logical relations between urbanization and urban land use structure, an analysis framework was established by two paths which are production （employment） and living （livelihood） that are the core meaning of the urbanization in this paper. Provincial panel data model was employed to examine the theoretical expectations. And the 29 provincial data from 2000 to 2009 was used. The results show that ： there is a significant positive correlation between the proportion of land for living and urbanization. The relationship between the proportion of productive land and urbanization shows an inverted U-shaped trend. It shows a significant positive correlation between urbanization and the rate of land for public facilities as well as the proportion of land for municipal utilities. And the regression coefficient presents a gradually decreasing trend from eastern to western China. The rate of road and square land shows a significant positive correlation to urbanization, and the regression coefficient of eastern China is bigger than that of western China. So it implies, compared to western China, that road construction in eastern China is much more useful for urbanization. There is a complex correlation between the proportion of external traffic land and urbanization from eastern to western China. It presents a significant positive correlation in the eastern region and a positive correlation which is not obvious in the central region, and the relationship between the two is negatively in the eastern China. It is a very useful method for governments to improve the level of urbanization by adjusting the urban land use structure.
