摘要
作为产学研合作的重要平台,企业博士后工作站对于产业转型升级背景下企业创新能力提升是否有效发挥作用及其影响机制值得深入研究。本文利用倾向得分匹配法,通过构建双重差分模型检验企业博士后工作站的设立对企业技术创新能力的影响。结果显示,企业博士后工作站的设立显著提升了企业的创新产出和创新质量,且设站质量与合作院校等级越高,企业创新产出提升效益越明显,该结论在一系列稳健性检验后依然成立。进一步检验后发现博士后工作站影响企业创新能力的作用机制在于其能够为企业带来平台效应与资金效应。同时,企业博士后工作站的创新提升效应仅在非国有企业和高新技术行业中显著存在。本文通过研究企业博士后工作站的创新机制与后果,丰富了产学研结合如何影响实体企业技术创新的微观经验证据,为优化企业博士后工作站相关政策提供了参考,同时为企业完善博士后工作站管理工作提供了方向。
As an important platform for enterprise-university-research cooperation,the postdoctoral workstation in enterprise is worthy of in-depth study on whether the improvement of corporate innovation ability can play an effective role and its impact mechanism in the context of industrial transformation and upgrading.In this paper,the propensity score matching method is used to test the influence of the establishment of postdoctoral workstation in enterprise on corporate innovation ability by building a difference in difference model.The results show that the establishment of postdoctoral workstation in enterprise significantly increases the number and quality of patent output.The higher the quality of the postdoctoral workstation and the level of cooperative colleges,the more obviously the efficiency of innovation output get improved.The conclusion is still valid through a series of robustness tests.Further investigation shows that the mechanism of postdoctoral workstations influencing the innovation ability of enterprises lies in platform effect and capital effect to the company.This paper also finds that the innovation promotion effect brought by the establishment of postdoctoral workstation is only significant in non-state-owned enterprises and high-tech industries.Through studying the innovation mechanism and consequences of postdoctoral workstation in the enterprise,this paper enriches and expands the micro empirical evidence of how the cooperation of company and university affects the technological innovation,provides reference for optimizing the relevant policies of postdoctoral workstation in China,and points out the direction for improving the management of postdoctoral workstation in enterprise.
