摘 要：This study adopts both the economic policy uncertainty (EPU) index from Baker et al (2016) and a newly constructed economic policy uncertainty index based onChinese newspapers (CEPU), utilizes Chinese imports and exports monthly data of about 5000 products (HS6 level) from January 2010 to April 2016, and examines the product heterogeneous effects of economic policy uncertainty on trade flows. We find that some products respond to economic policy uncertainty negatively, while some others positively. Further, we try to explain the heterogeneous effects by BEC categories, product differentiation, product sophistication, and market concentration. And we find that capital goods and consumption goods are more positive than intermediate goods responding to economic policy uncertainty, differentiated goods are more positive than homogenous goods, high sophistical goods are more positive than low sophistical goods, high concentrated goods are more positive than low concentrated goods. Besides, we find that CEPU performs much better than EPU, which indicates that big data context analysis should adopt Chinese sources rather than English sources.
