Intergenerational Efficiency of Farmland Conversion and Farmland Resource Loss in China

One of the requirements of sustainable utilization of resources is the efficiency of intergenerational allocation, which is important to the long-term utilization of resources. Based on the principle of efficient intergenerational allocation of resource in resource economics, this paper builds an ex post model to measure the efficiency of intergenerational allocation of farmland resource, and points out that with the continuous testing and modifying in practice according to the model results, the allocation of farmland resource in the future can continuously converge at the efficient allocation. This paper employs this model to test the allocation of the farmland resource from 1989 to 2003, and the result shows that if the test sample is divided into 1989 to 1996 period and 1997 to 2003 period, which due to the stricter farmland resource protection policy issued after 1996, the inefficient farmland conversion of the three main regions in China in the period of 1989 to 1996 was 6.58%, 6.84%, 7.85%, respectively.
