On the base of a brief literacy review of related research, this paper starts its research from the types of IB that met by Chinese export, analyzes the different trade barriers that Chinese export had encountered, and emphasizes the significant of measurements. Chinese products are facing some extent influences of IB when export, as many countries require certain marks to be adhered to the imported products thus add constraint conditions to their import and China’s export.
On the other hand, this conclude that IB has some negative effect on China’s quantity of export, term of trade and social welfare by a static analysis of the effect of IB to export. As China is becoming a big trade country, it could also gain some social benefits if it applies IB.
Finally, this paper takes mechanical and electrical products as example to do its analysis.
