| 摘 要： | 以企业技术能力为切入点,通过数理模型研究产学研合作与企业内部研发的互动模式(替代性和互补性),证明了企业的技术能力(主要是技术创新能力和技术吸收能力)在产学研合作与企业内部研发的互动中所具有的特殊的"门限"作用,即随着技术能力的提高,产学研合作与内部研发之间逐渐呈现出互补性。随后,利用辽宁省数据进行了实证检验,检验结果证实了企业技术能力"门限"效应的存在。在用工具变量控制内生性并剔除异常样本点的影响之后,检验结果在多数情况下依然保持稳健。此外,发明专利持有量、参与技术合作组织数量、企业规模和利润率等因素对于企业内部研发和产学研合作研发的平均投入金额均有重要影响。

| Abstract: | Taking Enterprise technical capabilities as the starting point,this paper studied using mathematical model the interactive modes of cooperative R&D and internal R&D(basically alternative mode or complementary mode).The technological capabilities of enterprises(mainly the ability of technological innovation and technology absorption capacity) in research cooperation plays the special role of the "threshold" in the interaction of cooperative and internal R&D,that is,with growth of the technical capabilities,research cooperation and internal R&D gradually showing complementary.Subsequently,using OLS,2SLS,3SLS to a survey data from Liaoning Province,we further confirmed the existence of "threshold" effects of enterprise technological capabilities.After making control over the endogeneous problem and excluding the abnormal samples,the results of the simultaneous equations model remained robust in most cases.In addition,the size of enterprise patent pool,the number of technical cooperation organizations in which the enterprise had participated,firm size,profitability and other factors has proved an important impact on the average investment amount of internal R&D and cooperative R&D. |
