Comparative Advantages of China's Foreign Trade from the Perspective of Ecological Footprint

To judge the sustainable development of China's trade, further transform the foreign trade structure and improve the ecological environment, the emergy ecological footprint theory was applied.Ecological footprints were used to quantitatively analyze the ecological impact and sustainability of international trade. The parameters of the traditional ecological footprint measurement algorithm were unstable, and the true ecological comparative advantage between regions was neglected. The calculation results were relatively more accurate. To reflect the distribution of ecological resources benefits of international trade, the ecological trade conditions were estimated for China's trade footprint from 2010-2016.The results showed that during this period, China's import and export trade footprint was basically balanced, and the ecological trade conditions tended to rise in the volatility. After that, the import footprint grown much faster than the export footprint. The net import footprint was increasing. Therefore, China's advantages in the sustainable management of biological resources reflect a certain comparative advantage in real trade. Certain biological resource export capabilities are formed. It further promotes the development of China's trade industry.
