| 摘 要： | 城市规模与空间结构影响城市空间利用效率,本文利用数据包络(DEA)分析方法测算我国227个地级市城市空间利用效率,并建立分析模型,验证城市规模、空间结构与碳排放强度之间的关系及作用机制。研究表明,土地财政推动土地非农化导致城市规模扩张,户籍制度阻碍劳动城市化导致城市空间结构不合理,这降低了城市空间利用效率,进而使得碳排放强度上升。我国可以通过纠正这种扭曲,提高空间利用效率、节约能源、降低碳排放强度从而达到减排目标。

| Abstract: | This paper summarizes the process of land and population urbanization,analyzes and evaluates 227 cities land use efficiency with data envelopment analysis.We build a model to analyze the relationship and Mechanism between city land utilization efficiency and carbon intensity.We find that over-urbanized land caused by land finance and incomplete-urbanized labor caused by household register system distort the ideal distribution of land and labor.The distortion decreases the land use efficiency and increase the carbon intensity.Chinese government can save the energy and decrease carbon intensity through the correction of the distortion. |
