英文摘要：

Does a country＇s power have an effect on its foreign trade？ Does a higher country evaluation promote one＇s export performance？ In this paper, a brand-new variable called country image is measured by global influence of World Opinion Poll conducted by BBC and introduced into traditional gravity model. We intend to evaluate how country images affect 17 countries＇ exports to 46 importers between 2006 to 2013 in the industrial level. Empirical evidence shows that a good national image can significantly promote the exports of a country and better access to the recognition and favor of importing countries. While further decomposing the exports into intensive and extensive margin, we find that countries with better image perform better not only in quantities but al- so in varieties. In addition, the impact of country image is varied with different types of export goods, and data shows it has the largest impact on consumer goods, and it also has a great impact on manufacture goods and heterogeneity goods.
