辽宁省城市土地利用效率及影响因素研究

Study on the Efficiency and Influencing Factors of Urban Land Use in Liaoning Province

以辽宁省沈阳市、大连市和12个地级市的城市土地为研究对象,基于2008—2017年辽宁省14个城市面板数据,运用数据包络分析(Data Envelopment Analysis,DEA)模型测算了各市城市土地利用静态效率;利用M almquist指数对其进行了动态对比评价;并通过Tobit模型分析了影响城市土地利用效率的主要因素及其作用方向;最后,得出了结论:辽宁省城市土地利用整体效率较高,但各市差异较明显,辽宁省城市土地利用和城市规模扩张之间存在不平衡发展关系,城市化率和工业废弃物利用率对城市土地利用效率有正向影响,旨在为辽宁省城市土地的高效可持续利用提供理论基础和数据支撑。

Taken urban land in Shenyang,Dalian and 12 prefecture-level cities in Liaoning Province as research object,based on 14 urban panel data in Liaoning Province from 2008 to 2017,the static efficiency of urban land use in cities is measured by Data Envelopment Analysis,DEA model and the Malmquist index is used for dynamic comparative evaluation.Through the Tobit model,the main influence factors and its effect direction of urban land use efficiency are analyzed.It is concluded that the urban land use efficiency is high in Liaoning Province,but the differences between cities are obvious;there is an imbalanced development relationship between urban land use and urban scale expansion in Liaoning Province;the urbanization rate and the industrial waste utilization rate have a positive promoting effect on urban land use efficiency and so on.The paper provides a theoretical basis and data support for the efficient use and sustainable development of urban land in Liaoning province.
