沈阳市城市土地利用效率评价及影响因素分析

Evaluation on the Efficiency of the Urban Land Utilization and Its Influencing Factors in Shenyang City

以沈阳市13个区县的城市土地为研究对象,运用超效率DEA测算了各区县2004—2010年城市土地利用静态效率并利用Malmquist模型进行了动态对比评价,最后以基于面板数据的Tobit模型探讨效率的影响因素。结果表明:(1)沈阳市各区县的城市土地整体上均达到高效利用;(2)全要素土地利用效率主要受技术进步指数的影响;(3)城镇化率、非农产业比重及地均固定资产投资对城市土地利用效率影响显著,且均为正相关。

The target in this paper is the urban land of thirteen counties in Shenyang City.The super-DEA was used to evaluate the static efficiency of the urban land utilization of the counties from 2004 to 2010.What's more,Malmquist index was calculated to appraise the dynamic efficiency and Tobit regression model based on panel data was applied to discuss the influencing factors of the efficiency.The results showed that the urban land of the counties in Shenyang City had achieved overall efficient use.The total factor efficiency of land use was mainly affected by the technological progress index.The urbanization rate,the proportion of non-agricultural industries and the average investment in fixed assets significantly affected the efficiency of the urban land utilization,and all of them caused the positive impact.
