【摘要】：本研究运用超效率SBM-DEA模型,估算了2000—2013年京津冀地区农业全要素用水效率,并在此基础上采用面板Tobit模型检验了自然条件、水利设施、农业生产状况和社会经济条件等因素对农业全要素用水效率的影响。结果表明:京津冀地区农业全要素用水效率虽然整体高于全国水平,但仍存在提升空间,其中河北省的农业节水潜力最大,未来应加强三地农业水资源的保护协作和节水技术共享;地下水占供水结构比例和农业生产资料价格指数对京津冀农业全要素用水效率有显著的正向影响,水库容量、牧渔业占农业总产值比例、户均耕地面积、农村家庭人均纯收入和农村劳动力素质对京津冀农业全要素用水效率有显著的负向影响。
[Abstract]:In this study, the water use efficiency of agricultural elements in Beijing-Tianjin-Hebei region from 2000 to 2013 was estimated by using super-efficiency SBM-DEA model, and on this basis, the natural conditions and water conservancy facilities were tested by panel Tobit model. The effect of agricultural production and social and economic conditions on the efficiency of agricultural water use. The results show that although the water use efficiency of all elements of agriculture in Beijing-Tianjin-Hebei region is higher than that of the whole country, there is still room for improvement, among which Hebei Province has the greatest agricultural water-saving potential. In the future, the protection and coordination of agricultural water resources and the sharing of water-saving technologies should be strengthened, and the proportion of groundwater to water supply structure and the price index of agricultural means of production have a significant positive impact on the water use efficiency of all agricultural elements in Beijing-Tianjin-Hebei, and the reservoir capacity. The ratio of animal husbandry and fishery to the total agricultural output value, the area of cultivated land per household, the per capita net income of rural households and the quality of rural labor force have a significant negative effect on the water use efficiency of all agricultural elements in Beijing-Tianjin-Hebei province.
