通过贸易便利化提高贸易效率已成为国际社会的共识,本文利用 OECD 最新编制的贸易便利化指数(TFI) ,采用2015年出口至美国的98国96部门的数据,运用负二项回归模型分析贸易便利化对出口多样化的影响.结果表明:贸易便利化对出口产品多样化有显著的促进作用,其中,对农产品出口多样化的作用要强于工业制成品,对高收入国家出口产品多样化影响最大;贸易便利化的不同措施对出口产品多样化的影响程度存在差异,在11种贸易便利化措施中,只有"边境机构的内部合作"的影响不显著,其他10个贸易便利化措施对出口产品多样化均存在显著的促进作用,而"程序性手续"影响最大.实证结果反映了"后关税时代"贸易便利化的重要性,为推动贸易便利化提供了理论支持,对我国贸易便利化建设和外贸转型政策也提供了参考.%It has become a consensus of the international community to improve trade efficiency through trade facilitation. The paper uses the trade facilitation indicators (TFI) compiled by the OECD and the data of 98 countries (regions) ex－ports to the United States involving 96 sectors in 2015 to analyze the effect of trade facilitation on export diversification with negative binomial regression.The results show that the trade facilitation has a significant impact on the diversification of export products, especially, has a more significant effect on export diversification of agricultural products than manu－factured goods, and has the greatest impact on the diversification of export products in high－income countries (regions);the impacts of different measures for trade facilitation on the diversification of export products are different: among the 11 trade facilitation measures, only the "Co－operation internal" coefficient doesn't pass the significant test, the other 10 trade facilitation measures have significant effects on the diversification of export products, and the impact of "Formalities Procedures" is the greatest.The empirical results indicate the importance of trade facilitation in the "post－tariff era", provide theoretical support for promoting trade facilitation, and provide reference for China's trade facilitation construction and transformation of China's foreign trade policy.
