【摘要】：以我國(guó)31個(gè)省份為例,運(yùn)用三階段DEA模型和空間計(jì)量模型對(duì)各省農(nóng)業(yè)用水效率及其溢出效應(yīng)進(jìn)行測(cè)評(píng)與分析。結(jié)果表明:我國(guó)絕大多數(shù)省份農(nóng)業(yè)用水效率較低,農(nóng)業(yè)用水效率提升空間較大。同時(shí),農(nóng)業(yè)用水效率的外部環(huán)境變量對(duì)各省份農(nóng)業(yè)用水效率的測(cè)評(píng)結(jié)果影響明顯,剔除外部環(huán)境變量的農(nóng)業(yè)用水效率值更能真實(shí)反映真實(shí)效率。在考察各省農(nóng)業(yè)用水效率存在空間相關(guān)性基礎(chǔ)上,利用空間滯后項(xiàng)模型分析了農(nóng)業(yè)用水效率的空間溢出效應(yīng),各省農(nóng)業(yè)用水效率不僅受到本省各變量因素影響,還受到空間相鄰省份影響,表現(xiàn)出明顯的空間溢出效應(yīng)。
[Abstract]:Taking 31 provinces in China as an example, the efficiency of agricultural water use and its spillover effects are evaluated and analyzed by using the three-stage DEA model and the spatial econometric model. The results show that the efficiency of agricultural water use is low in most provinces of China, and the space for improving the efficiency of agricultural water use is larger. At the same time, the external environmental variables of agricultural water use efficiency have a significant impact on the evaluation results of agricultural water use efficiency in various provinces. The agricultural water use efficiency value excluding external environmental variables can reflect the real efficiency more truly. The spatial spillover effect of agricultural water use efficiency is analyzed by using spatial lag term model on the basis of investigating the spatial correlation of agricultural water use efficiency in each province. The agricultural water use efficiency in each province is not only affected by the variables of the province. It is also affected by adjacent provinces, showing obvious spatial spillover effect.
