知识产权保护与企业全球价值链位置——基于中间产品供需的视角

IPR Protection and the Position of Enterprises’ Global Value Chain——From the Perspective of Intermediate Products’ Supply and Demand

本文通过构建企业层面知识产权保护指数,基于供求视角测算了企业出口全球价值链位置;从企业在全球价值链中作为中间产品供给者和需求者的双重角色出发,实证分析了企业层面知识产权保护对企业出口价值链位置的影响。研究发现:从供给视角来看,加强知识产权保护可以扩大企业产权优势,促进创新,进而促进企业出口在全球价值链中的上游度提升;从需求视角来看,强化知识产权保护会造成企业低端锁定,影响企业出口在全球价值链中的下游度提升。综合来看,强化知识产权保护引致价值链延伸效应,深化全球分工,对于中国企业全球价值链相对位置的攀升具有明显的促进作用,价值链攀升效应大于低端锁定效应。

Based on the micro-enterprise level,this paper constructed the IPR protection index and measured the position of enterprises’export global value chain from the perspective of supply and demand.Considering enterprises’dual roles—suppliers and demanders of intermediate products—in the global value chain,this paper empirically analyzed impacts of IPR protection at the micro-enterprise level on the position of enterprises’export value chain.The study finds that from the perspective of supply,IPR protection is strengthened by expanding the advantages of enterprises’property rights and promoting innovation,which can finally enhance the upstreamness of enterprises’export in the global value chain;from the perspective of demand,strengthening IPR protection will make the formation of enterprises’low-end locking.Then the downstreamness of enterprises’export in the global value chain will be improved.On the whole,strengthening IPR protection has produced the value chain extension effect and deepened the global division of labor,which has a significant role in obviously promoting Chinese enterprises’relative position in global value chain.The value chain climbing effect is greater than the low-end locking effect.
