环境规制、要素禀赋与出口贸易的动态关系——基于我国污染密集产业的动态面板数据

环境规制和要素禀赋均会影响某地区的比较优势,但环境规制对出口贸易的影响存在不确定性,特别是对于污染密集型产业来说。文章建立产业环境污染指数来定义污染密集型产业,同时建立环境规制强度评价体系来计算产业的环境规制强度,并以HOV模型为基础建立动态面板方程,对我国污染最为密集的四个行业的环境规制和出口贸易进行估计。估计的结果表明环境规制对我国污染密集型产业出口贸易的影响是显著的,出口量和环境规制程度之间呈现出"U"型的关系,而且在现有经济水平下大多数制造业处于拐点左侧,环境规制强度的提高仍不利于产业发展和出口贸易。

Dynamic Relationship between Environment Regulations,Factor Endowment and Export Trade:A Study Based on the Dynamic Panel Data of Pollution-intensive Industries in China

Environmental regulation and factor endowment will affect a region’s comparative advantage,but there is a pervasive uncertainty about the influence of environmental regulation on exports,especially for pollution-intensive industries.In this paper,the index of industrial pollution is established to define the pollution-intensive industry while an evaluation system for environmental regulation is built to calculate the stringency of industrial environmental regulation.In addition,it establishes a dynamic panel data model on the basis of HOV model to estimate the relationship between environment regulation and export trade for the four most pollution-intensive industries.The results show that environmental regulation has a significant impact on the export of pollution-intensive industries,and in the current economic level,the increase of environmental regulation is still not conducive to industrial development and export trade.
