中国城市群土地利用结构与效率研究

Research on Land Use Structure and Efficiency of Urban Agglomerations in China

土地作为城市经济发展的载体,其利用结构与效率能够反映区域经济规模和发展水平,对促进城市群经济社会可持续发展具有重要作用。文章通过运用洛伦兹曲线-基尼系数法和SE-DEA模型方法对中国城市群的土地利用结构和利用效率进行定量分析。结果表明:中国城市群土地利用结构呈现明显的用地类型特征,东、中、西部地区城市群土地利用结构存在明显差异;中国城市群土地利用效率普遍不高,但从时间演化上来看,土地利用效率总体呈上升趋势,城市群土地利用效率呈现东部普遍较高、中部差异较大、西部普遍较低的空间特征。

As a carrier of urban economic development, land utilization structure and efficiency can reflect the economic scale and development level of the region, and plays an important role in promoting the sustainable economic and social development of urban agglomerations. The paper uses Lorentz curve-Gini coefficient method and SE-DEA model to quantitatively analyze the land use structure and utilization efficiency of Chinese urban agglomerations. The results show that the land use structure of urban agglomerations in China presents obvious characteristics of land use types,with obvious differences in land use structure of urban agglomerations in eastern, central and western regions, and that the land use efficiency of urban agglomerations in China is generally low, but from the perspective of time evolution, the overall land use efficiency presents an upward trend, with the land utilization efficiency of urban agglomeration generally higher in the east, greatly different in the middle and lower in the west.
