摘 要:为了解由于农业补贴政策的实施可能会导致化肥投入增加及农业面源污染加重的问题,在对农业补贴政策、要素投入和农业面源污染之间的关系进行阐述的基础上,采用2004—2009年分省的面板数据,构建化肥的需求函数,具体分析补贴对化肥投入量的影响。回归结果表明,农业补贴并没有使化肥的投入量显著增加,由此得出结论,农业补贴政策的实施并没有加重由化肥引起的农业面源污染。Since Chinese government began to implement agricultural subsidy policy in 2004,it has achieved its goal in terms of improving grain yield and farmers' income. However, it is also important to pay attention to the issue whether agricultural subsidy has some distortion on agricultural inputs, further affecting adversely on the environment such as agricultural non-point pollution. More chemical fertilizer might be used to improve grain yield after agricultural subsidy. If so,subsidy would be blamed for aggravating agricultural non-point pollution, in this study, the impact of subsidy on chemical fertilizer as input was analyzed by employing province level panel data to regress fertilizer demand function based on the theoretical model of agricultural subsidy, inputs and agricultural non-point pollution. The conclusion is that agricultural subsidy doesn't induce more chemical fertilizer usage, which implies that agricultural subsidy doesn't aggravate agricultural non-point pollution.
