摘 要:本文在构建双向固定效应模型的基础上,利用1992—2014年中国30个省区的相关统计数据,研究畜牧业环境规制对生猪产业转移的影响,以验证“污染避难所”效应是否存在。结果表明:从全国层面而言,环境规制有效推动了生猪产业的区域间转移,存在显著的“污染避难所”效应,且当期较为成熟的环境规制对生猪产业的影响程度最强,早期实施的环境规制对生猪产业转移的影响会随时间向前推移而逐渐减弱;从区域层面而言,在我国东、中、西部三大区域内,环境规制对生猪产业转移均具有显著的促进作用,其中在东部地区这一作用最强,而中、西部地区相对较弱。

Abstract: This paper establishes the model of two-way fixed effects, using the summarized statistical data in the 30 provinces of China in 1992—2014, and then empirically examines the effect of environmental regulation of animal husbandry on the regional transfer of pig industry, in order to verify whether the “Pollution Haven Hypothesis” exists. The results show that the environmental regulation can effectively promote the regional transfer of pig industry, therefore the “Pollution Haven Hypothesis” is verified. And the relatively perfect environmental regulation policies have relatively strong influence on pig industry, whereas the effect of the environmental regulation policies which was implemented from the past years on regional pig industrial transfer will be weakened over time. By region, environmental regulation promote the regional transfer of pig industry significantly both in the eastern, central and western areas, and the effect is most prominent in eastern areas of China and then in central and west areas.

Key words: Environmental regulation; Regional transfer of pig industry; Pollution haven hypothesis; Two-way fixed effects
