| 内容提要 | 本文克服了单一产品企业假定的严重缺陷，基于新近发展的多产品企业异质性贸易模型框架，利用2000-2005年的中国海关进出口数据库和中国工业企业数据库，全面系统地刻画了中国多产品出口企业及其产品范围的特征性事实，并利用拓展的引力模型，揭示隐藏在其背后的经济力量。本文的主要发现是，多产品出口企业主导了中国的出口贸易。特别的，2000-2005年间，中国出口增长的大约44%来自企业内的扩展边际，集约的边际不是中国出口增长的主导力量。进一步的，利用拓展的引力模型对总体层面、分企业所有权属性和贸易方式的不同回归结果，都揭示了影响中国出口企业产品范围的经济力量的稳健性。我们的研究，重新诠释了中国出口增长的动力来源，企业内的扩展边际作为中国出口增长的主导力量被首次揭示出来。这一发现，不仅颠覆了现有基于单一产品假定企业异质性贸易模型对中国出口增长进行经验研究的结论，更为重要的是，它明确地提醒我们在进行贸易结构调整时，不应仅仅关注企业间的扩展边际的重要性，更应高度重视企业内的扩展边际的贡献。 |
| Abstract | Based on the multi-product firm heterogeneous trade model, this paper overcomes the serious shortage of the single product assumption. Using the databases of the Chinese Customs Trade Statistics (CCTS) and the Chinese Annual Survey of Industrial Firms (CASIF) from 2000-2005, this paper depicts comprehensively the stylized facts of China’s multi-product firms and product scope, and makes use of the extended gravity model to reveal the economic factors which affecting on the firm’s product scope. The main findings are: the multi-product firms dominate China’s exports; about 44% of China’s export growth is from the extensive margin within firm in 2000-2005. Hereafter, using the extended gravity model, we regress according to the whole sample, firm ownership and trade pattern, the results are robust. Our research reinterprets the power source of China’s export growth----the extensive margin within firm is discovered firstly, which overturns the results of the single product firm heterogeneous trade model and reminds us to attention the attribution of the extensive margin within firm when we adjust trade structure. |
