This paper studies whether Chinese export products sophistication has differential impact on the negative effect of trade barriers on Chinese export. Our theoretical model is based on the analysis of consumer demand, considering that the consumer can get more utilities from the more sophisticated products, and we construct the interaction model in the empirical analysis by which we find the higher export products sophistication is, the lower the negative effect of trade barriers is. This implies that the promotion of the Chinese export products sophistication is an effective way to help Chinese export step over the trade barriers. In the further empirical analysis, we find that the less developed the country to which Chinese products export is, the more the promotion of export products sophistication reduces the negative effect of trade barriers on Chinese export. This paper will provide inspiration for China about how to step over the trade barriers and promote the export.
