基于DEA的城市土地利用效率#br#时空差异及影响因素分析#br##br#——以吉林省9地市为例#br#

摘要： 土地的利用效率在不同地区以及不同时期都会有所不同，以吉林省9个地级市的城市土地利用为研究对象，运用DEA方法测算了吉林省9个地级市在2007~2016年期间城市土地利用效率，从时空两个维度对影响城市土地利用效率的因素进行了分析。研究表明：（1）吉林省城市土地利用效率整体偏低，在空间上呈现出中部地区高，东西部地区低的分布格局，在2007~2016年期间土地利用效率呈下降趋势。（2）影响吉林省9地市城市土地利用效率的因素：投入方面，第二、三产业从业人数冗余尤为突出，固定资产投资也存在相对过剩；产出方面，财政收入与城镇居民可支配收入不足等成为重要的经济影响因素，环境产出效益不足，生态因素对土地利用效率的影响在研究期内开始显现。（3）研究对策：通过合理分配劳动力资源，同时注重提高土地利用的经济效率和生态效率是提高吉林省土地利用效率的现实途径。

Analysis of Spatial and Temporal Differences and Influencing Factors#br#of Urban land Use Efficiency Based on DEA:#br#A Case Study of 9 Cities in Jilin Province#br#

Abstract：land use efficiency Varies a lot in different regions and at different times and in different periods.Based on the calculated data from 2007 to 2016,this research aims at investigating factors of urban land use efficiency as the research object,the method of DEA was used to calculate the land use efficiency of these cities in Jilin Province.Factors affecting urban land use efficiency were analyzed in across time and space.The result showed that:(1)The overall urban land use efficiency was relatively low in Jilin province,featuring a spatial distribution pattern of high efficiency in the central region and relatively low ones in western and eastern regions.Besides,the land use efficiency showed a downward trend Showed a decline;(2)Factors affecting the urban land use efficiency of these 9 cities:In terms of input,the number of employees in the secondary and tertiary industries was particularly redundant,and there was a relative surplus in fixed assets investment;In the aspect of output,insufficient fiscal revenue and income of urban residents had became important economic factors, The effect of ecological factors on land use efficiency began to appear during the research period.(3)Countermeasures:By rationally allocating labor resources while paying attention to improving the economic efficiency and ecological efficiency of land use is a realistic way to improve the land use efficiency of Jilin Province.
