摘　　要：运用德尔菲法对各个阶段的农民土地产权强度进行了定量化,并在此基础上建立C-D生产函数模型,进行计量分析,结果发现:农民土地产权强度与农业产出之间呈显著的正相关,其弹性系数为0.106;农民土地产权强度与农业产出之间呈倒"U"形关系,当农民土地产权强度为88.8左右时,农业产出达到最大。现阶段,农民土地产权强度还低于该数值,需要进一步加以提高。未来一段时期内,中国农地制度改革的方向应该是不断采取措施增加农民土地产权强度,提高农业生产绩效。This paper makes quantitative the strength of farmers land property rights in different stages by u- sing Delphi method, on the basis of which it establishes the C-D production function model and makes quanti- tative analysis. The result shows there are two main conclusions. Firstly, the strength of farmers land property rights promotes the agricultural performance in China. A 1% increase in the strength of farmers land property rights would result in a 0. 106% increase in the agricultural output. Secondly, the relation between the strength of farmers land property rights and agricultural performance is the inverted U shape. When the strength of farmers land property rights is around 88.8, the agricultural output reaches the maximum. As the strength of farmers land property rights is lower at present, we must take some measures to enhance it. In the future, the reform on farmland institution in China should aim to raise the strength of farmers land property rights step by step in order to improve agricultural performance.
