在Chenery经济结构转化理论基础上,概括了我国转型阶段经济发展中的耕地问题,并回顾了经济与耕地资源变化的相关研究。运用2009年国际截面数据,对经济结构与耕地变化之间的Kuznets曲线进行了检验,结果表明,经济发展水平与耕地变化之间不是倒U型,而是更为复杂的N型关系,经济结构转变中农业劳动力、耕地向工业或城市的转移以及农业份额的下降均会引起耕地资源的减少。提出转型期经济结构转型与耕地保护相融的三点建议。
On the basis of Chenery’s theory of economic structure transformation, this paper summarizes the problem of cultivated land in the economic development in the transitional period of our country and reviews the related research on the change of the economy and cultivated land resources. Using the 2009 international cross-section data, the Kuznets curve between economic structure and cultivated land change has been tested. The results show that the relationship between economic development and cultivated land change is not an inverted U, but a more complex N-type relationship. The economic structure The changing agricultural labor force, the transfer of arable land to industry or cities, and the declining share of agriculture all contribute to the reduction of cultivated land resources. Put forward three proposals on the combination of the transition of economic structure and the protection of cultivated land during the transition period.
