碳排放与出口贸易竞争力关系的实证分析——以中美贸易为例

在过去的五年里，中国的碳排放量几乎双倍增加，目前已经成为世界最大的碳排放国。多数研究发现，出口是碳排放量增加的主要原因。本文以此为出发点，构建了衡量出口贸易竞争力和碳排放的相对指标，通过协整检验、因果关系检验等实证分析，考察1990—2007年间我国和美国的相对排放和相对市场占有率，发现我国出口贸易竞争力指标和碳排放之间存在稳定的线性关系，并且互为Granger原因。

An Analysis of the Relationship between Carbon Emissions and Export Competitiveness: focusing on China-US Trade Practices

Over the past five years, China＇ s carbon emissions almost doubled, and China is expected to be the world＇ s largest country of carbon emissions. Studies have shown that exports are the main reasons for car- bon emissions. This paper constructs the related indices of trade competitiveness and environment by using co- integration tests, causality tests, and empirical analysis of relative emissions and relative market shares between China and the United States from 1990 to 2007. The research results show that there is a linear relationship be- tween China＇ s export competitiveness and carbon emissions, and there exists a Granger cause between each other.
