关于贸易开放、经济发展和环境的文献在很大程度上对贸易的环境后果没有定论。本研究将贸易和收入视为内生的，并使用工具变量技术估计贸易开放对环境质量的总体影响。我们发现，贸易是否对环境产生有益影响取决于污染物和国家。经合组织国家认为贸易有利于环境。然而，它对非经合组织国家的二氧化硫（SO（2））和二氧化碳（CO（2））排放量有不利影响，尽管它确实降低了这些国家的生化需氧量（BOD）排放量。经过动态调整后，虽然短期内影响较小，但长期来看影响较大。(C)2009 Elsevier Inc. All rights reserved.
The literature on trade openness, economic development, and the environment is largely inconclusive about the environmental consequences of trade. This study treats trade and income as endogenous and estimates the overall impact of trade openness on environmental quality using the instrumental variables technique. We find that whether or not trade has a beneficial effect on the environment varies depending on the pollutant and the country. Trade is found to benefit the environment in OECD countries. It has detrimental effects, however, on sulfur dioxide (SO(2)) and carbon dioxide (CO(2)) emissions in non-OECD countries, although it does lower biochemical oxygen demand (BOD) emissions in these countries. We also find the impact is large in the long term, after the dynamic adjustment process, although it is small in the short term. (C) 2009 Elsevier Inc. All rights reserved.
