Abstract: In recent ten years, the global trade volume has achieved amazing leap-forward growth, and the relationship between free trade and environment has become increasingly acute. On the one hand, many developed countries use unequal trade and investment means to grab a lot of strategic resources from developing countries, but it has caused serious imbalance in the ecological environment of these countries; On the other hand, the blind pursuit of trade expansion, capital accumulation and industrialization has actually aggravated the deterioration of the global environment. The "squeezing" restriction of environmental effects on trade has increasingly become the focus of international trade development. In this context, introducing environmental variables to promote the sustainability of trade strategy has become an inevitable way to realize the scientific development of China's foreign trade.
