Arable Land Conservation Effects of Land Supervision in China
摘要
Abstract
The purpose of this study aimed to assess the effects of land supervision on the conversion of arable land to construction use.The question about this is defined whether land supervision has saved arable land from conversion to construction use, and if so, how much the effect is.The province-level panel data from 1999 to 2008 were collected, and the fixed-effects model, random-effects model and pooled OLS model were applied to estimate the equations.The test on those models suggests that the fixed-effects model is more appropriate than random-effects model and pooled OLS model.The effectiveness of land supervision on the conversion of arable land to constructionuse was evaluated based on the statistical significance of variables about land supervision and by computing the difference of arable land area converted to constructionusc land with and without land supervision in effect.The result shows that land supervision has provided a measurable degree of decreasing arable land conversion to construction use; the area of arable land conversion to construction purpose decreased about 261 ha with a 1％ increment of rate of special land supervision, and the area of arable land conversion to construction purpose decreased about 929 ha with a 1％ increment of rate of regular land supervision.Moreover, the loss of arable land due to construction use in 2007 and 2008 respectively decreased 32 160.52 ha and 6 442.90 ha because of special land supervision in effect, which is about 7.08％ and 3.36％ of actual farmland loss due to construction use in 2007 and 2008; the loss of arable land due to construction use in 2008 decreased 41 127.79 ha because of regular land supervision in effect, which is about 21.5％ of the actual farmland loss due to construction use in 2008.The last but not the least, the loss of arable land due to construction use in 2007 and 2008 respectively decreased 32 160.52 ha and 47 570.70 ha because of both special land supervision and regular land supervision in effect, which is about 7.08％ and 24.83％ of the actual farmland loss due to construction use in 2007 and 2008.关键词
