中文摘要：

以新一新贸易理论为基础，利用CEPIIBACI国际贸易数据库1996—2011年我国对十六个主要贸易伙伴国的微观层面出口数据，将出口增长总量分解为集约边际和扩展边际，通过动态面板数据模型GMM估计方法实证分析贸易促进机构对我国出口增长二元边际的影响，结果显示：贸易促进机构对出口增长集约边际和扩展边际具有显著的正向影响，对出口增长扩展边际的促进作用大于集约边际；贸易促进委员会比驻外使领馆对出口增长发挥的效力更为明显；贸易促进机构对中高技术行业产品出口增长二元边际的促进作用大于中低技术行业产品。因此，我国应增加贸易促进机构的数量，尤其要增设贸易促进委员会。

英文摘要：

On the basis of the new-new trade theory, this paper makes use of the micro-level ex- port data of China＇s international trade with sixteen major trading partners from CEPII BACI intema- tional trade database of 1996-2011 and decomposes the total export growth into the intensive margin and expansion margin, so as to conduct an empirical analysis of the impact of trade promotion agen- cy on China＇s export binary marginal growth with the GMM dynamic panel data model estimation method. The results show that trade promotion agency has a significant positive impact on the inten- sive margin and expansion margin of export growth, the promoting effect on the export growth ex- pansion margin is greater than that on the intensive margin. The trade promotion committees can play more significant role in promoting export than embassies and consulates stationed abroad. The promot- ing effect of trade promotion agencies on export growth binary margin of medium and high-tech in- dustry products is larger than that on the medium and lower technology industry products. Therefore, China should increase the number of trade promotion agencies, in particular, have more Trade Promo- tion Committees.
