土地督察对土地市场化的影响效果评估

为评估土地督察对土地市场化的影响,论文把目标分解为两个问题:即土地督察制度的实施是否对土地市场化程度产生影响;如果有影响,影响的效果如何。论文收集了2003—2009年的省级面板数据,基于固定效应和随机效应模型估计了土地督察对土地市场化的影响。通过相关检验,采用了固定效应模型的估计结果,并在模型估计的基础上,对影响效果进行了评价。结果表明:①土地督察对土地市场化的发展有积极的促进作用,2007—2009年专项督察覆盖度每提高1%,约能促进土地市场化程度提升0.14%,例行督察覆盖度每提高1%,约能促进土地市场化程度提升1.12%;②通过实施专项督察,2007—2009年全国土地市场化程度分别提升了2.06%、 0.19%和0.55%,通过实行例行督察,2008—2009年全国土地市场化程度分别提升5.01%和12.47%;③2007—2009年通过开展土地督察,全国土地市场化程度分别提高了2.04%、 5.21%和13.02%。

Effects of Land Supervision on Land Marketization in China

The purpose of this study is to analyze whether the implementation of land supervision is effective in land marketization and assess the extent of the effects.Based on province-level panel data from 2003 to 2008,methods of fixed-effects model and random-effects model were employed to estimate the equations.The test on the models suggests that the fixed-effects model is more appropriate than random-effects model.The effects of land supervision on land marketization were evaluated on the basis of the estimation of the fixed-effects model.The results show that: 1) Land supervision has played a positive role in land marketization in China from 2007 to 2009.The growth of every percentage point in special land supervision coverage brought about 0.14% growth in land marketization degree.The growth of every percentage point in regular land supervision coverage brought about 1.12% growth in land marketization degree.2) Land marketization degree in China respectively increased 2.06%,0.19% and 0.55% in 2007,2008 and 2009 because of the implementation of special land supervision;land marketization degree respectively increased 5.01% and 12.47% in 2008 and 2009 because of the implementation of regular land supervision.3) On the whole,the implementation of land supervision has promoted the degree of land marketization in China,and accordingly land marketization degree respectively increased 2.04%,5.21% and 13.02% in 2007,2008 and 2009.The implementation of land supervision has effectively promoted the development of land marketization.Land supervision on land use and management of local government should be further strengthened,especially in implementing special land supervision on the act of excessive and illegal intervention in land supply of local government,in order to reduce the existence of gray land market and promote the healthy and stable development of land market.
