【摘要】：研究目標:農(nóng)業(yè)用水效率在區(qū)域?qū)用娴目臻g交互影響效應。研究方法:利用Global超效率DEA模型和全要素用水效率指標測度中國省際農(nóng)業(yè)用水效率,并首次采用VAR框架下的脈沖響應函數(shù)識別中國農(nóng)業(yè)用水效率的空間交互影響效應。研究發(fā)現(xiàn):中國農(nóng)業(yè)用水效率呈持續(xù)升高趨勢;在空間格局上呈東高西低、南高北低的總體分布態(tài)勢;由于中國農(nóng)業(yè)用水效率的集聚特征僅體現(xiàn)在小范圍地區(qū),而在整體上未呈現(xiàn)明顯的空間集聚特征,傳統(tǒng)的空間計量模型并不適用于識別農(nóng)業(yè)用水效率的空間交互影響。研究創(chuàng)新:基于VAR框架下的脈沖響應函數(shù)分析結(jié)果表明,不同區(qū)域的農(nóng)業(yè)用水效率之間確實存在空間交互影響。研究價值:充分利用空間交互影響效應實現(xiàn)農(nóng)業(yè)用水效率的空間協(xié)同提升。
[Abstract]:Research objective: spatial interaction effect of agricultural water use efficiency at the regional level. Methods: using Global super-efficiency DEA model and all-factor water use efficiency index to measure the interprovincial agricultural water use efficiency in China. For the first time, the impulse response function based on VAR framework is used to identify the spatial interaction effect of agricultural water use efficiency in China. It is found that the agricultural water use efficiency of China is increasing continuously, and the spatial pattern of agricultural water use efficiency is low in the east, high in the east and low in the west. Because the agglomeration characteristics of agricultural water use efficiency in China are only reflected in a small area, but there is no obvious spatial agglomeration feature in the whole, The traditional spatial metering model is not suitable to identify the spatial interaction of agricultural water use efficiency. Research innovation: the impulse response function analysis based on VAR framework shows that, There does exist spatial interaction between agricultural water use efficiency in different regions. Research value: fully utilize spatial interaction effect to achieve spatial coordination enhancement of agricultural water use efficiency.
