报告简介：

We develop a general equilibrium trade model with pollution as a by-product of production to study the interaction between international trade and the environment. We quantitatively evaluate two related hypotheses: the Pollution Haven Effect (PHE), which states that environmental regulation is a comparative advantage force, and the Pollution Haven Hypothesis (PHH), which states that a reduction in trade barriers causes pollution-intensive industries to concentrate in countries with weak environmental stringency. Our results suggest that, even though the PHE exists, the PHH is unsupported. This is because that environmental policy stringency, as a crucial determinant of pollution emission and abatement, is weak in determining international specialization. By comparing environmental stringency with other determinants of international trade, we identify productivity and trade cost as the major forces that suppress the PHE, resulting in the failure of the PHH. In addition, strategic environmental policy is an ineffective substitute for trade policy yet bears serious environmental consequences. Without international coordination and cooperation, a reduction in trade costs will induce more worldwide pollution emission even though countries will experience higher income levels.
