摘要
研究目的:针对当前盲目征收耕地的现象,探讨耕地征收最优规模测算方法,为科学调控耕地征收提供参考依据。研究方法:生产函数模型与面板计量方法。研究结果:2005—2010年耕地征收实际规模从过度征收逐步趋近于最优规模;"十二五"期间需新增耕地规模为153.27万hm2。研究结论:(1)基于边际理论视角测算耕地征收最优规模的方法具有科学性和可操作性,可为各地合理确定耕地征收规模和土地利用总体规划修编提供参考;(2)保障粮食安全前提下的耕地效益最大化是确定当前最优征收规模的标准;(3)提升耕地的边际效益是解决当前耕地保护与建设用地扩张矛盾的关键。
The purpose of this paper is to explore a new calculation method for the optimal scale of arable land expropriation in order to provide reference for the scientific regulation on arable land expropriation. Methods of the production function model and the panel data model were employed. The results show that the actual scale of the arable land expropriations in the period of 2005-2010 are gradually changed from excessively expropriating to the optimal scale. During the 12th five-year plan, the additional arable land scale is calculation of optimal arable land expropriation scale based on marginal about 1,532,700 hm2. It is concluded that 1 ）the theory is scientific and feasible for operational, and it can provide a reference for determine the land expropriation scale in land use planning; 2）maximizing the benefits of arable land expropriation should be under the premise of ensuring food security; 3）enhancing the marginal benefits of the arable land is the key to solve the current contradiction between protection of arable land and expansion of construction land.
