非意愿产出视角下农地城市流转效率测度及政策建议——以鄂西生态圈与江汉平原为例

Policy Implication and Measurement of Rural-urban Land Conversion Efficiency from the Perspective of Undesirable Output

本文运用数据包络分析(DEA)中的Bad Output Model,将碳排放量纳入测度农地城市流转效率的指标体系内,从两个不同角度测算了碳排放量,并以此为前提定义了两种不同的效率;然后以十堰市和荆州市为代表,测算鄂西生态圈与江汉平原的农地城市流转效率;最后比较了两个区域的效率,并提出两个区域效率提升的改进措施。本文为测度农地城市流转效率提供新的视角,且从生态保护及土地发展权转移的角度为研究区域提供政策建议。

Using bad output model of DEA,this paper brings the carbon emission into the index system of rural-urban land conversion efficiency,measures the carbon emission and defines the two types of efficiency.Based on study cases in Shiyan and Jingzhou,this paper measures and compares the rural-urban land conversion efficiency in West-Hubei Ecological Circle and Jianghan Plain,and proposes improvement measures about increasing efficiency.In sum,this paper provides new perspectives to measure rural-urban land conversion efficiency,and proposes policy suggestions from the perspective of ecological protection and transfer of land development right.
