知识产权治理如何提升产业链韧性?——基于国家知识产权示范城市政策的实证检验

How Can Intellectual Property Governance Improve the Resilience of the Industrial Chain?--An Empirical Test Based on National Intellectual Property Model City Policy

良好的产权制度是提升产业链韧性的有效基础,作为知识产权治理工具的知识产权示范城市政策是知识产权制度在城市地理空间上的创新实践。本文基于2003—2016年280个城市面板数据,利用多时点双重差分的方法检验知识产权示范城市政策对产业链韧性提升的影响效应,结合中介效应模型探讨其作用机制。结果表明:知识产权示范城市的设立能够显著提升城市产业多样化水平和创新能力,进而提升城市产业链韧性,揭示了知识产权治理能够有效提升产业链韧性的结论;知识多样化和政府科技支持是该政策提升产业链韧性的有效渠道,但二者的作用效果并未达到理想状态。进一步分析发现:该政策的实施对产业链韧性的提升效应存在区域和城市规模异质性,其中东部和南部地区的政策效应更为显著,人口中等及以上的城市以及经济较发达地区的政策效应更为显著。研究结论为知识产权治理和产业链韧性的研究提供了经验证据,为政府协调资源配置和培育产业链韧性提供了参考。

A good property right institution lays an effective foundation for improving the resilience of the industrial chain.The intellectual property model city policy as a tool for intellectual property governance is an innovative practice of the intellectual property system in the urban geographic space.Based on 280 urban panel data from 2003-2016,the paper used the DID method to test the effect of intellectual property model city policies on the improvement of industrial chain resilience,and explored its mechanism with the mediation effect model.The results indicate that the establishment of intellectual property model cities can significantly improve the level of urban industry diversification and innovation ability,and thus enhance the resilience of urban industrial chain.Knowledge diversification and government science and technology support are effective channels for the policy to improve the resilience of the industrial chain,but the effect has not reached its ideal state.Further analysis finds that there are regional and urban scale heterogeneity in the improvement effect of the implementation of the policy on the resilience of the industrial chain,among which the policy effect in the eastern and southern regions is more significant,and the policy effect in cities with medium population and above,as well as more economically developed regions,is more significant.The conclusions of the research provide empirical evidence for the research on intellectual property governance and industrial chain resilience,and provide reference for the government to coordinate resource allocation and cultivate industrial chain resilience.
