产品知识产权保护与中国产业链供应链来源地多元化

Intellectual Property Protection of Products and China’s Source Diversification of Industrial and Supply Chains

基于细化至产品层面的产业链供应链结构关系,本文探究了知识产权保护通过水平、上下游渠道对中国产供链来源地多元化的影响。研究表明,加强产品水平知识产权保护对中国产供链来源地多元化的影响不显著,而加强产品上游知识产权保护产生了抑制效应,加强产品下游知识产权保护产生了促进作用。具体地,加强水平知识产权保护通过市场扩张渠道对产供链来源地多元化产生了促进作用,但也通过市场势力和本土竞争渠道产生了抑制效应,造成相互抵消。加强上游知识产权保护能够通过本土投入品渠道对产供链来源地多元化产生抑制效应,而进口投入品的渠道影响不显著。加强下游知识产权保护通过下游创新渠道对产供链来源地多元化产生了促进作用,但下游的议价渠道削弱了这一促进作用。据此,在强化产品知识产权保护的同时需要统筹考虑产业链供应链的上下游联系,并落实好反垄断政策。

Based on the structural relationship of industrial and supply chains(ISC)of product level,we investigate the impact of intellectual property protection(IPP)on China’s source diversification of ISC through horizontal,upstream and downstream channels.Results show that strengthening horizontal IPP of products does not produce significant effect on China’s source diversification of ISC,while strengthening upstream IPP of products causes curbing effect,and strengthening downstream IPP of products brings about promotional effect.Specifically,the strengthening makes a promotional effect through market expansion channel,but offset by a depressive effect through market power and local competition.Meanwhile,strengthening upstream IPP of products makes depressive effect through local input channel,but the effect from import input is not significant.In a contrast,strengthening downstream IPP makes a promotional effect through downstream channel innovation,but this effect is weakened by downstream bargaining channels.Based on the findings above,the governments need to integrate upstream and downstream linkages of ISC when strengthening product IPP,also needs to implement anti-monopoly policy better.
