摘　　要：本文基于Chaney(2008)的理论框架,构建了中国电子信息产品出口二元边际决定因素的计量模型,并利用中国112种HS6位数的电子信息产品对47个贸易伙伴1996-2010年的数据实证检验了决定中国电子信息产品出口二元边际扩张的主要因素。应用随机效应模型对面板数据的检验结果表明相对经济规模及降低固定贸易成本对中国电子信息产品出口二元边际扩张产生积极影响,可变贸易成本则对其产生负面影响。双边自由贸易协定对出口集约边际的影响较小,而对出口扩展边际的影响不显著,因此应当加快签订双边自由贸易协定,从而促进中国二元边际出口扩张。According to recently developed models of trade studies assuming imperfect competition and heterogeneous firms, lower trade costs help increase bilateral trade through a rise in both the intensive and extensive margins of trade. This paper purports to provide new empirical evidence for the determinants of the two margins in China＇s electronic information trade. Using highly disaggregated data of China＇s electronics exports over the period 1996-2010, this paper describes a stylized fact of the binary-margin existence in China＇s electronic ex- ports. Based on studies of Chaney （2008）, this paper further evaluates the factors that influence such a binary margin in China＇s electronic exports. The results indicate that higher GDP and lower transportation costs have positive effect on the two margins, while FTA is associated with a small positive effect on the intensive margin and little effect on the extensive margin.
