农地产权转移中的代际配置损失测度 ———以四川省乐至县为例

该文从资源代际配置的基本原理出发,引入逻辑斯蒂曲线模拟农地产权转移中的最优农地产权转移数量,构建了资源代际配置检验模型。根据国家相关土地利用政策,把四川省乐至县1989～2008年期间划分为三个时间段,对这三个时段的农地产权转移数量配置进行了测度。研究显示,1989～1996年时段的农地产权转移效率小于1997～2003年和2004～2008年时段,1997～2003年小于2004～2008年时段。此三时段平均效率损失分别是30%、7.3%和-30%,反映出1989～1996年时段的产权转移数量过度以及代际配置效率相对低效。因此,未来时段的政策应该进一步控制农地转移速度,确保农地资源代际配置的效率。

INTERGENERATIONAL ALLOCATION LOSS MEASUREMENT OF PROPERTY RIGHT CONVERSION ON AGRICULTURAL LAND

Based on the principle of resource intergenerational allocation,this paper adopted logistic curve to simulate optimal allocation of agricultural land in the course of property right transfer,built a model to measure the efficiency of intergenerational allocation of agricultural land.According to related land utilization policies,this paper measured the efficiency of intergenerational allocation from 1989 to 2008,which was divided into three periods.The results showed that the efficiency of property right transfer in from 1989 to 1996 was lower than that in from 1997 to 2003 and in 2004 to 2008,while in 1997 to 2003 is lower than that in 2004 to 2008.The average efficiency losses the three periods were 30 %,7.3%,and-30%,respectively,which indicated that the quantity of agricultural land transfer from 1989 to 1996 was excessive and the efficiency of intergenerational allocation was low.So it suggested controlling the speed of agricultural land transfer to ensure the efficiency of intergenerational allocation.
