为了解决农村水利供给不足、供给效率不高等问题,需要改进农村水利供给模式。分别对政府供给、市场参与农村水利供给、协会及第三部门供给优势与效率损失进行了分析。接着,采用向量自回归(VAR)方法,实证量化不同供给主体下的协同效应水平,得出国家财政投入与有效灌溉面积之间存在Granger因果关系,企业私人投资、银行贷款、农户自筹投资能够增加有效灌溉面积,但不能有效构成有效灌溉面积增加的Granger因果关系。因此,需要建立以政府投入为主导、政府与市场相结合农村水利供给体系。

In order to solve the low efficiency supply problems of the rural water conservancy, it is necessary to improve water conservancy supply mode. Respectively Compare about advantages and efficiency loss to the government supplies, the market supplies, associations and the third departments supply water conservancy supply . Then, using vector autoregressive (VAR) method, empirical quantitative synergies under different supply main body levels, it is concluded that between the state financial input and effective irrigation area is Granger causality , private investment, bank loans, farmers raise investment can increase the effective irrigation area, but it can"t effectively constitute effective irrigation area of the increasing number of Granger causality. Therefore, we need to establish a supply system under government investment as the leading factor, and the combination of government and the market of rural water conservancy.
