摘　　要：本文采用企业异质性贸易模型,利用中国工业企业和海关贸易统计库的合并数据将中国出口总量增长分解为出口的扩展边际和出口的集约边际,在此基础上实证研究了中间品进口对二元边际的影响。结果显示,中间品进口对企业出口扩展边际和集约边际都具有积极的促进作用;通过系数标准化发现,中间品进口的促进作用更多体现在集约边际而非扩展边际;分样本检验中,发现中间品进口来源国、贸易方式以及所有制类型会对促进作用产生显著影响。本文的发现为中国出口贸易扩展主要源于集约边际提供了一个科学的解释,也为中国对外贸易政策的调整与转型提拱了参考依据。Based on the analytical framework of the trade model of heteroge- neous firms and Chinese combined with data from industrial enterprises and the Customs Trade Statistics, the paper carries out an empirical study on the effects of intermediate goods imports on the extensive margin and the intensive margin. The results show that the imported intermediate goods play a positive role in pro- moting the extensive margin and the intensive margin. But through the standard- ization of the factor, the paper finds that the promoting role of the intermediate goods is more obvious on the intensive margin. It also finds that the source countries of the intermediate imports, trade modes and enterprises＇ ownership types have significant impacts on the promoting effect. This paper provides not only scientific explanations for the expansion of Chinese intermediate goods imports on the intensive margin but also references for China to adjust and trans- form its foreign trade policies.
