生态环境建设对我国西部农业发展的贡献实证研究——以内蒙古自治区为例

Study on the Contribution of Ecological Environment Construction to Western Agricultural Development

西部大开发4年来的退耕还林(草)战略的实施,不仅使西部区草原植被得到一定程度的恢复,森林覆盖率迅速提高,而且改善了生态环境,促进了农业生产的发展。文章旨在通过计量经济模型的建立,运用计量经济软件Eviews,以内蒙古自治区为例确定生态环境与我国西部农业经济增长之间的数量关系:森林面积每增加1%,则农业总产值增长6.3303个百分点。这对于我国进一步推进退耕还林(草)战略、改善西部区域生态环境、促进西部农业经济发展具有重要的实践意义。

Implement of the policy of exploiting western China in 4 years not only renews the prairie, makes the rate of coverage of forest ＆ prairie increase, but also accelerates the agricultural production. This article, for the case of Inner Mongolia on the basis of economics model, reveals the quantitative relation between returning land to forests and the agricultural development, by the econometrics soft wear Eviews. The result shows that the relation stands on the high level： the growth of 1% of forest area can lead to the growth rate for 2. 7678 % of the agricu!tural production. This result is of great significance for further pushing the policies of returning land to forests, accelerating western economy development, so as to realize regional economic development in equilibrium.
