中国土地用途管制制度的耕地保护绩效及其区域差异研究

Study on Cultivated Land Preservation Performance of Land Use Control System and Its Regional Differences in China

研究目的:定量分析中国土地用途管制制度的耕地保护绩效及其省际差异,探讨耕地保护绩效的可提升潜力空间,以期为该项制度的坚持与完善提供实证依据。研究方法:虚拟变量模型法,统计分析法。研究结果:运用虚拟变量模型,采用基本建设投资作为变量因子,定量研究了土地用途管制在全国尺度的耕地保护绩效;构建耕地保护绩效系数ICLPE,据此定量分析了耕地保护绩效的省际差异;依据综合指标对中国30个省区的耕地保护绩效进行了4级分级。研究结论:中国土地用途管制制度有效阻滞了建设占用耕地的速度,对于缓解人地矛盾,保证粮食安全,有积极作用,值得充分肯定,应长期坚持;耕地保护绩效表现出明显的省际差异,应继续完善该项制度,进一步提升耕地保护效率。

The purpose of the paper is to study quantitatively the performance of land use control system on the cultivated land preservation in China and provincial differences,as well as finding ways for improvement in order to offer demonstration for the persistence and improvement of the policy.Methods employed include Model of Dummy Variable and statistic analysis.The performance of land use control system was studied with Dummy Variable,adopting basic construction investment as a variable factor.The ICLPE,a coef...
