【摘要】 本文在构建理论模型的基础上,使用中国规模以上制造业企业数据,对知识产权保护状况对企业创新投入的影响进行了研究。本文发现,知识产权侵权程度对企业的研发确实具有很强的抑制作用,且负面影响并不能够通过事后查处的方式得到完全消除。除此之外,知识产权保护状况对于不同企业的影响存在显著差异:相对于国有企业来说,非国有企业创新投入受知识产权保护的影响更大;竞争程度较高的行业中的企业创新投入受到知识产权保护的影响也更大。本文的发现表明,对知识产权的保护不应仅局限于对事后侵权行为的惩罚,还应包括对潜在侵权行为的事前防范,这样才能更加有效地激励企业进行创新研发。更多还原

【Abstract】 This paper presents both theoretical and empirical study about how the level of intellectual property protection(IPP) would affect firms’ innovation input,by using the data of China’s above- scale manufacturing enterprises.The main finding of this paper is that the provincial level of infringement activities has a significantly negative effect on the R&D input of firms,and such an effect could only be partly off- set by the government efforts in punishing the infringe activities.Moreover,the non- state- owned enterprises(compared to stated-owned enterprises) and firms in more competitive industries are found to be more sensitive to the status of IPP.Such findings suggest that the punishment afterwards and prevention in advance should be both taken by government to encourage firm’s innovation.更多还原
