Trade and the Environment: New Methods, Measurements, and Results
综述了国际贸易与环境关系的最新研究，通过分解排放变化与生产活动的关系，提出三个新假设，为未来研究指明方向。
We review recent research linking international trade to the environment, with a focus on new results and methods. The review is given structure by a novel decomposition linking changes in emissions to changes in productive activity at the plant, firm, industry, and national levels. Although some new results have emerged from the application of a Melitz-style approach to trade and the environment, the full potential of this approach has not yet been realized. We discuss existing empirical and theoretical work, introduce three new hypotheses, and suggest paths for future researchers to follow.
