本文利用1999—2009年间省际面板数据,以化肥为例分析要素市场扭曲是否激发了农业面源污染物排放。研究发现,国家对化肥行业的价格管制政策以及国家对农民实施补贴的财政支农政策导致了化肥要素市场扭曲的存在;截止到2009年,中国化肥要素市场扭曲程度一直呈现出上升趋势;利用GMM动态面板模型实证研究表明中国广泛存在的化肥要素市场扭曲对化肥农业面源污染物排放有显著的激发作用。
This article uses inter-provincial panel data from 1999 to 2009 to analyze whether factors of market distortions have stimulated the emission of agricultural non-point source pollutants. The study found that the price control policy of the fertilizer industry in the country and the financial supportive agriculture policy of the state subsidizing the peasants led to the distortion of the fertilizer factor market. As of 2009, the distortion of the fertilizer factor market in China has been on an upward trend. The GMM The dynamic panel model empirical research shows that the widespread distortion of fertilizer market in China has a significant stimulating effect on the emission of fertilizer non-point source pollutants.
