摘　　要：本文利用1995-2011年中国产品出口SITC五位编码数据,测算了二元边际对中国不同生产要素密集型产品出口增长的贡献率。结果显示,所有类别产品的出口增长都主要是沿着集约边际实现的,并且对其越来越依赖。其中,集约边际贡献最大的为劳动密集型产品,最小的是人力资本密集型产品。在此基础上,对各类产品出口二元边际影响因素的实证分析结果表明：进口国经济规模越大,无论对于中国出口的现有产品和新产品都有更多的需求,但对于前者需求强度更大;同时,虚拟变量的回归结果表明随着贸易成本的降低,各类出口产品都更趋向于单一化而不是多样化。Using the SITC-5 trade data for the period of 1995-2011, this paper calculates the dual margins of China＇s export growth for different factor-intensive products. The results indicate that the export of all kinds of products mainly grows via the intensive margin, and such export growth is increasingly dependent on intensive margin. Labor- intensive products make the largest intensive margin contribution, while the human capital intensive products make the smallest. An empirical analysis of the factors affecting dual margins indicates that, the demand for existing and new products exported from China increases along with the enlargement of the economy scale of an import country, with a greater demand for the existing products. Additionally, the regression results of dummy variable show that a reduction of trade costs often leads to the simplification, rather than the diversification, of all kinds of export products.
