英文摘要：
  In the 1990s, China started a process of structural reforms and of trade liberalization, which was followed by the accession to the World Trade Organization (WTO) in 2001. In this paper, we analyze trade patterns of Chinese firms for the period 2000-2006, characterized by a notable increase in exports volumes. Theoretically, in a more open economy, firms are expected to move from the production of a set of less-competitive products towards more internationally competitive ones, which implies specialization. We study several stylized facts on the distribution of Chinese firms trade and growth rates, and we analyze whether firms have diversified or specialized their trade patterns between 2000 and 2006. We show that Chinese export patterns are very heterogeneous, that the volatility of growth rates depends on the level of exports, and that volatility is stronger after trade liberalization. Both, diversification in products and destinations have a positive impact on trade growth, but diversification of destinations has a stronger effect. We conclude that the success of Chinese exports is not only due to an increase in the intensive margin, related to the existence of economies of scale, but also due to an increase in the extensive margin, related to the existence of economies of scope.

中文摘要：
20世纪90年代，中国开始了结构改革和贸易自由化进程，随后于2001年加入世界贸易组织（WTO）。本文分析了2000-2006年中国企业的贸易模式，其特点是出口量显著增长。理论上，在一个更加开放的经济体中，企业有望从生产一系列竞争力较低的产品转向更具国际竞争力的产品，这意味着专业化。我们研究了中国企业贸易和增长率分布的几个典型事实，并分析了2000年至2006年间企业贸易模式是否多样化或专业化。我们表明，中国的出口模式是非常异质的，增长率的波动取决于出口水平，贸易自由化后的波动更大。产品和目的地的多样化都会对贸易增长产生积极影响，但目的地的多样化会产生更大的影响。我们得出的结论是，中国出口的成功不仅在于集约利润的增加，这与规模经济的存在有关，而且在于广泛利润的增加，这与范围经济的存在有关。
