强化知识产权司法保护有助于企业创新吗——来自知识产权法院设立的证据

Does Strengthening the Juridical Protection of Intellectual Property Contribute to Corporate Innovation?Evidences from the Establishment of Courts for Intellectual Property Right Cases

强化知识产权司法保护对激发社会创新活力具有重要意义。2014年北京、上海和广州三地知识产权法院的设立,为研究知识产权司法保护强化对企业创新的影响提供了一个准自然实验场景。基于2007—2016年222个地级市的2155家上市公司数据的实证分析表明,我国知识产权保护水平仍处于"最优知识产权论"的有效创新激励阶段,知识产权法院设立对于知识产权保护法治的强化显著地促进了企业创新。知识产权法院通过优化自主创新司法环境、激励企业研发投入、减少企业研发收益损失等机制促进了企业创新。因此,强化知识产权保护立法与执法联动、推进知识产权保护司法机构专门化是完善我国知识产权法治体系、进一步促进社会创新的有力举措。

Strengthening the judicial protection of intellectual property rights is of great significance to stimulate the vitality of social innovation.The establishments of intellectual property right courts in Beijing,Shanghai and Guangzhou in 2014 have provided the scenario of quasi-natural experiment for the studies of the impacts of strengthening juridical protection of intellectual property on corporate innovation.The empirical analysis based on the data of 2155 listed companies in 222 prefecture-level cities from 2007 to 2016 reveals that the level of China’s intellectual property rights protection is still at the efficient innovation motivation stage of“optimal intellectual property theory”,and that strengthening the rule of law for intellectual property rights protection by the establishment of intellectual property right courts has significantly promoted corporate innovation.The intellectual property courts have promoted corporate innovation through optimizing the juridical environment for independent innovation,encouraging enterprises’R&D investment,reducing the losses in corporate R&D profits and other mechanisms.Therefore,to strengthen the linkage between legislation and law enforcement of intellectual property rights protection and to promote the specialization of judicial institutions of intellectual property rights protection is a powerful measure to improve China’s rule of law system for intellectual property rights and to further promote social innovations.
