校企合作提升了制造业企业的技术创新绩效吗?——基于倾向得分匹配方法的实证研究

Does University-industry Collaboration Improve the Technological Innovation Performance of Manufacturing Firms? An Empirical Study Based on Propensity Score Matching Method

在创新驱动发展战略实施和制造业转型升级的背景下,研究校企合作对中国制造业企业技术创新绩效的影响具有重要的理论与现实意义。将企业技术创新绩效划分为产品创新绩效和流程创新绩效,使用世界银行最新的中国制造业企业调查数据,利用倾向得分匹配法探究校企合作对企业技术创新绩效的影响。研究结果表明:校企合作对中国制造业企业技术创新绩效具有显著的促进作用,且其对产品创新绩效的正向影响大于其对流程创新绩效的影响;企业的校企合作行为具有“自选择”特征,利用倾向得分匹配方法能够有效克服样本选择偏差问题,得出更为可靠的估计结果。进一步的异质性分析发现,校企合作对不同规模、年龄企业技术创新绩效的影响存在异质性。

Under the background of the implementation of innovation-driven development strategy and the transformation and upgrading of manufacturing industry,it is of great theoretical and practical significance to study the impact of university-industry collaboration on the technological innovation performance of Chinese manufacturing firms.The effect of university-industry collaboration on the technological innovation performance of firm was analyzed by dividing technological innovation performance into product innovation performance and process innovation performance.The World Bank’s latest survey data of Chinese manufacturing firms and the propensity score matching(PSM)method were also utilized in the analysis.It is found that university-industry collaboration has a significant positive impact on the technological innovation performance of Chinese manufacturing firms,and its positive impact on product innovation performance is greater than that on process innovation performance.The university-industry collaboration behavior of firms has the characteristics of“self selection”,while the PSM method can effectively overcome the sample selection bias and obtain more reliable estimation results.Further heterogeneity analysis shows that the impact of university-industry collaboration on the technological innovation performance of firms of different sizes and ages is heterogeneous.
