摘　　要：本文运用中国海关数据,从多产品企业的微观视角分解了中国出口增长的二元边际,发现融入产品维度和市场维度后,随时间动态变化的扩展边际对出口增长的贡献略高于集约边际,而随截面静态变化的集约边际在中国出口增长中发挥主要作用。运用扩展的引力模型分析二元边际的影响因素发现,贸易成本主要通过扩展边际影响中国的出口增长,其中对中国出口企业数量的影响尤为显著。为此,中国应进一步降低多产品企业的出口成本,以扩展边际的增长提高中国出口企业数量并实现出口的多元化增长。Using China's customs data,this paper decomposes China's export growth into dual margins from the perspective of multiproduct firms. It is found that the extensive margin's contribution to export growth is slightly higher than the intensive margin following approach of time dynamic change after considering product and market-dimension,while the intensive margin explains most of the export growth following approach of cross-section static change. Using augmented gravity model to analyze the impact of different trade costs on export margins,it is found that the impact of trade costs on China's export mainly through extensive margins, especially the number of export firms. Therefore,China should reduce trade costs and support multiproduct export firms to increase extensive margins by increasing the number of export firms and realize a diversified export growth.
