摘    要:开放式创新成为企业获取外部知识资源、提升创新能力的重要途径之一。目前将内部R&D投入和外部知识获取同时作为调节变量综合考虑其对创新绩效影响的研究成果较为欠缺。论文以我国制造业领域企业为研究对象,在文献回顾和述评基础上,基于科技统计数据和2,905样本企业数据,借鉴Tobit 估计模型,实证分析企业内部R&D投入和外部知识获取这两类R&D活动对创新绩效的影响。研究表明:逐渐依赖于外部R&D活动、获取外部知识资源的企业具有较高创新绩效水平,但当超过一定临界值的时候,会产生替代效应,即更多参与外部R&D活动会使企业绩效水平下降;对于知识储备较高的高技术企业来说,进一步开放R&D创新边界,其机会成本相对较高。

关 键 词:内部R&D投入  外部资源获取  创新绩效

Abstract:Open innovation has become one of the important ways of obtaining external knowledge resources and enhancing innovation capability of enterprises. In the field of innovation performance, the literature of comprehensive consideration of internal R&D investment and external Knowledge acquisition are relatively few. Based on literature review and commentary, this paper examines the in?uence of R&D con?guration on innovative performance and the moderating role of a ?rm’s R&D capacity in China's manufacturing industry with reference of the Tobit estimation model. It’s data is from S&T statistics data and 2,905 sample enterprises. The ?ndings suggest that ?rms that increasingly rely on external R&D activities have a better innovative performance, yet up to a point. Beyond this threshold, a greater share of external R&D activities reduces a ?rm’s innovative performance. And such substitution effect is larger for ?rms with greater R&D capacity. This paper provides a better understanding opportunity cost for further opening up R&D borders is higher for ?rms with a superior technological knowledge stock.
Keywords:internal R&D investment  external knowledge acquisition  innovative performance
