摘　　要：2019年突发新冠肺炎疫情给规上工业企业R&D投入产出带来严重的影响,合理规划R&D投入产出,对规避风险具有重要理论指导意义。在分析新冠肺炎爆发前后规上工业企业R&D投入产出情况的基础上,以规上工业企业R&D活动中新产品产出率、出口率、技术效率、有效技术效率为解释变量,企业R&D活动情况作为控制变量建立模型,运用改进的知识生产函数构建模型,采用SPSS26软件对模型进行回归分析,研究R&D投入产出溢出效应。研究表明,新冠肺炎疫情发生前后规上工业企业R&D新产品产出率和新产品出口率、技术效率和有效技术效率对溢出效应均产生了不同程度的影响;不同调节因素下表现出的显著性水平不同。其中,疫情发生后新产品出口率在5%水平下影响显著。The sudden outbreak of COVID-19 in 2019 brought serious risks and challenges to the R&D input and output of industrial enterprises on the scale.It is of certain theoretical significance to propose solutions and countermeasures and reasonably plan the R&D input and output.Based on the analysis of the R&D input-output situation of industrial enterprises before and after the outbreak of COVID-19,a model was established with the output rate,export rate,technical efficiency and effective technical efficiency of new products in R&D activities of industrial enterprises as explanatory variables,and the R&D activities of enterprises as control variables.The improved knowledge production function was used to construct the model.SPSS26 software was used for regression analysis to study the spillover effect of R&D input and output.The results show that output rate and export rate of new product in the R&D,technical efficiency and effective technical efficiency of industrial enterprises before and after the outbreak of the COVID-19 epidemic have different impact on the spillover effect.Different modifiers exhibited different levels of significance.Among them,the export rate of new products has a significant impact at the 5%level.after the outbreak of the epidemic.
