土地督察制度实施对耕地占补数量平衡效果评估

为评估土地督察对耕地占补数量平衡的影响,该文把目标分解为2个问题,即土地督察制度的实施是否对耕地占补平衡产生影响;如果有影响,影响的效果如何。该文收集了2003-2008年的省级面板数据,基于随机效应Tobit回归模型估计了土地督察对耕地占补平衡的效果,在模型估计结果的基础上,对土地督察的耕地占补平衡效果进行了评估。结果表明:1)2007-2008年土地督察对耕地占补平衡有积极的促进作用,专项督察覆盖度每提高1%,约能促进耕地占补比例提升1.47%,例行督察覆盖度每提高1%,约能促进耕地占补比例提升5.59%。2)通过实施专项督察,2007-2008年分别促进了耕地补充1939.39和318.81m2,占当年耕地补充总面积的9.88%和1.36%;通过实施例行督察,2008年促进了耕地补充29106.36hm2,约占当年耕地补充总面积的12.68%。3)2007-2008年通过土地督察分别促进了耕地补充1939.39和3225.17m2,占当年耕地补充总面积的9.88%和14.03%。

Effects of land supervision on cultivated land requisition-compensation balance in China

The purpose of this study is to analyze whether the implement of land supervision is effective in cultivated land requisition-compensation and to assess the size of the effects.Based on province-level panel data from 2003 to 2008,random effects Tobit model was employed.The results show that:1) land supervision plays a positive role in cultivated land requisition-compensation.The growth of every percentage point in special land supervision coverage will bring about nearly 1.47% growth in cultivated land requisition-compensation.The growth of every percentage point in regular land supervision coverage will bring about nearly 5.59% growth in cultivated land requisition-compensation.2) The implement of special land supervision promotes cultivated land compensation.Cultivated land quantity respectively increases 19 339.39 hm2 and 3 118.81 hm2 in 2007 and 2008,accounting for 9.88% and 1.36% of the total area of cultivated land compensation.Regular land supervision works effectively as well to cultivated land compensation in the current year.Compensatory cultivated land scale reaches 29 106.36 hm2.It accounts for 12.68% of the total area of cultivated land compensation.3) Land supervision accelerates the process of cultivated land compensation.The area of cultivated land compensation is 19 339.39 hm2 and 32 225.17 hm2 respectively,accounting for 9.88% and 14.03% of the total area of cultivated land compensation in 2007 and 2008.
