【摘要】：为探究生猪产业集聚对水体氮污染的影响,选取2003—2015年我国20个生猪主要产销区的面板数据,在IPAT分析框架下估算了养殖造成的水体氮污染,并构建了IPATM—EKC模型,实证分析了生猪产业集聚程度与水体氮污染之间的关系。研究发现:北方养殖水污染程度较轻,但北方养殖造成的水污染量逐年增加,相关部门应对北方生猪养殖水污染给予足够的重视;生猪产业集聚程度与养殖水污染的关系呈"U"型,且我国绝大部分地区处于曲线的下降阶段,增加产业集聚程度可以减少养殖水污染。文章从产业集聚的不同驱动因素对实证结果进行解释,并依据实证结果给出了相应的政策建议。
[Abstract]:In order to explore the effect of the cluster of pig industry on the nitrogen pollution in the water body , the paper selects the panel data of the main production areas of 20 pigs in China from 2003 to 2015 , and establishes the IPATM - EKC model . The relationship between the concentration degree of the pig industry and the nitrogen pollution in the water body is analyzed . The research indicates that the relationship between the concentration degree of the pig industry and the water pollution of the water body increases year by year , and the related departments should pay enough attention to the water pollution in the northern pig breeding . The paper explains the empirical results from the different driving factors of the industrial agglomeration , and gives the corresponding policy recommendations according to the empirical results .
