产学研合作对企业创新绩效影响的倾向得分估计研究——广东省部产学研合作实证

Empirical Research on Innovation Effects of University Industry Collative Innovation Based on Propensity Score Matching Method

针对企业产学研合作创新政策效应评价时由企业"自选择"带来的因果干涉问题,引入计量经济学中非参数的倾向得分匹配法(PSM),运用广东省部产学研计划的实证数据,研究探讨了产学研合作对企业技术创新绩效的政策效应。研究结果表明,参与和未参与产学研合作的企业在技术创新绩效和企业特征方面均存在显著差异;通过排除选择性偏倚与混杂偏倚,产学研合作对企业新产品销售收入比重的提升具有显著的正向影响,而对企业获取专利有正向影响但不显著。

Focus on the ＇cause and effect＇ problem in the evaluation of policy effects of university industry cooper- ation innovation, this paper, by employing the econometrics non-parametric propensity score matching method, as- sessed the policy effects of university industry cooperation on enterprise innovation performance, using the data of university industry cooperation plan by Guangdong province. The empirical results indicate that innovation perfor- mance and enterprise＇s characteristics were significant different between involved and not involved enterprises. Al- so, it turns out that university industry cooperation has significant positive effects on the proportion of new prod- ucts sales, and has positive but no-significant effects on granted patent, by eliminating selection bias and confound- ing bias
