环境规制对企业出口贸易影响的实证研究——基于2004—2015年中国企业出口的省际面板数据

文章利用2004—2015年中国企业出口的面板数据，采用OLS和LSDV的估计方法，实证检验了中国环境规制水平对企业出口贸易的影响。研究表明，内生环境规制水平能有效提升企业出口竞争力，但严格的外生环境规制对企业出口贸易的影响呈U型。按区域划分进一步研究显示，东部和中部地区的外生环境规制与企业出口贸易间的关系呈倒U型关系，而西部却呈U型关系。因此，文章建议中国政府要提高环境规制，但需因地制宜，对不同地区实行弹性的环境规制政策，以实现中国各地区企业出口竞争力稳定均衡地提高。

An Empirical Study of Environmental Regulation on Enterprise Export:Based on the Provincial Panel Data of Chinese Enterprises Exported from 2004 to 2015

Based on the panel data for export of China enterprises from 2004 to 2015, this paper empirically tests the impact of China's environmental regulations on the export trade of enterprises with estimation methods of OLS and LSDV. The study shows that the internal environmental regulation can effectively improve the export competitiveness of enterprises, but the effect of strict exogenous environmental regulation on the export trade of enterprises is a U type. Further research based on the regional division shows that the relationship between the external environmental regulation and the export trade of the east and central regions is an inverted U, while the western part is a U type. Therefore, this paper suggests that Chinese government should improve the intensity of environmental regulation, but need to adjust measures to local conditions, and implement elasticity environmental regulation policies in different regions, so as to achieve stable and equilibrium export competitiveness of enterprises in all regions of China.
