农田水利设施建设对农业生产影响的实证研究

利用2000-2011年全国26个省份及东、中、西部地区的面板数据，运用柯布—道格拉斯（C-D）生产函数模型，对全国及东、中、西部地区农田水利设施建设对农业生产的影响进行了实证研究。研究结果表明，农业生产的影响主要来自有效灌溉面积、受灾面积和乡村办水电站装机容量；农作物总播种面积对东、中、西部三大地区农业总产值产生了不同的影响。

Empirical Study on the Influence of Irrigation and Water Conservancy Facilities on Agricultural?Production

Using the panel data of 26 provinces and eastern, central and western regions form 2000 to 2011, Cobb Douglas production?function model is adopted to analyze the influence of irrigation and water conservancy facilities on agricultural?production. The results show that the impact of agricultural production mainly comes from the effective irrigation area, disaster area and rural hydropower installed capacity; total sown area of farm crops had different influence on the agriculture?output?value in eastern, central and western regions.
