摘要: 本文通过改进现有产品复杂度测算方法,计算得到中国企业出口技术含量后,从行业上下游和水平渠道的角度研究表明:加强省级知识产权保护通过上游渠道提升了企业出口技术含量,而通过水平和下游渠道不利于企业出口技术含量的提升;加强省级-上游行业知识产权保护通过投入品技术渠道提高了企业出口技术含量,但强上游议价能力会削弱其提升作用;加强省级-水平行业知识产权保护分别通过创新渠道和阻碍溢出渠道对企业出口技术含量产生混合影响;加强省级-下游行业知识产权保护抑制了强下游议价能力行业中企业出口技术含量的提升,但企业强知识吸收能力会弱化其抑制效应。据此,政府在加强知识产权保护时,需要区分行业上下游和水平渠道,配合创新支持和反垄断政策,以推动企业技术升级。

Abstract: After improving the existing method of measuring product complexity, this paper calculates the export technology content of Chinese enterprises, drawing a clear distinction among upstream, downstream and horizontal industry channels, and finds that:(i) strengthening provincial intellectual property protection (IPP) can improve the export technology content of enterprises through the upstream industrial channels, while making it worse through horizontal and downstream industrial channels; and (ii) strengthening provincial IPP in upstream industries through technological input channels has increased the export technology content of enterprises, but the strong bargaining power of the upstream industry may weaken its promotional effect. The strengthening of provincial IPP in horizontal industries has had mixed effects on the export technology content of enterprises through the innovation channel and preventing tech-spillover channel. The strengthening of provincial IPP within downstream industries has inhibited improvement in the export technology content of enterprises in industries facing strong downstream bargaining power, but enterprises' strong knowledge-absorbing capacity can weaken its suppression effect. Consequently, when strengthening the IPP, the government need distinguish among upstream, downstream and horizontal industrial channels, and coordinate its support of innovation and antitrust policies, in order to promote the technological upgrading of Chinese enterprises.
