摘要: 基于企业异质性贸易理论框架,本文首先从理论上分析了出口市场的知识产权保护对企业出口二元边际的作用机制。随后,利用2000-2006年中国海关统计的企业出口数据将中国出口增长分解为扩展边际和集约边际,运用扩展的贸易引力模型实证考察了知识产权保护和不同类型的贸易成本对中国出口二元边际的影响。结果表明,知识产权保护通过降低企业出口的固定成本提高了扩展边际,但降低了集约边际,知识产权保护主要通过扩展边际促进了中国的出口增长。本文还发现,经济规模、固定贸易成本、地理距离主要通过扩展边际影响了中国的出口。上述结论对于区分不同贸易方式、不同所有制企业和知识产权保护不同测算指标的估计依然稳健。

Abstract: It analyzes the impact mechanism of intellectual property rights protection on the dual margins of enterprise’s export with the framework of heterogeneous firm trade theory. Then, it decomposes the export growth into extensive margin and intensive margin by using the firm export data from 2000 to 2006 in China, and investigates empirically the effect of intellectual property rights protection on the dual margins of export by using the extended trade gravity model. The results show that the extensive margin is improved by reducing fixed cost of export enterprise because of the intellectual property rights protection, while the intensive margin is decreased. And the intellectual property rights protection promotes China’s export growth mainly through extensive margin. In addition, the effects of economic size, fixed trade cost and geographic distances on China’s export growth also work exert mainly through extensive margin. The above results are robust for the estimation of different trade modes, different ownership firms and different indicators dictators of intellectual property rights protection.
