摘　　要：产学研联盟一直是中国政府促进技术创新的一项重要国策。产学研联盟如何影响我国企业的创新,现有文献尚未给出一致的答案。不同于以往研究,本文基于发明专利IPC信息,研究了产学研联盟影响创业板公司技术创新的作用机理,以此来检验产学研联盟的政策效果。在使用"匹配法和双重差分模型"之后,本文研究发现,产学研联盟对企业技术多元化具有显著的积极影响。在使用动态分析模型后,进一步发现这一积极作用具有明显的滞后效应。本文为我们深入认识产学研联盟政策的实际效果提供了理论基础和经验证据,并为政府和企业完善产学研联盟和进一步深化自主创新提供了决策依据和政策建议。Industry-university research alliances(IURA)are an important national policy for Chinese government to accelerate technological innovation.However,it is still not clear that how IURA impact corporate innovation.Unlike prior studies,we analyzed the impact of IURA and its mechanism on corporate innovation to examine their policy effects based on IPC information of inventions,taking the companies of the ChiNext market as the research object.Our results show that IURA have a positive impact on technological diversification after using propensity score matching method and difference-in-differences regressions.Moreover,we further find that the impact has a significant lagged effect after using dynamic analysis model.This paper provides theory and empirical evidence for our insight into real effects of Chinese IURA policy.In addition,it also provides meaningful policy implications for China’s government and firms to perfect IURA policy and enhance innovation capability.
