利用外部知识实现创新已经成为我国企业创新实践的常用策略。究竟内部R&D和外部知识搜寻之间存在怎样的关系,过多的外部知识搜寻是否会削弱企业内部R&D的战略性地位?本文基于209家中国创新型企业的问卷调查数据,对企业内部R&D活动和外部知识搜寻之间的关系进行了实证分析。研究结果表明外部知识搜寻对提升企业创新绩效有重要影响,但是不同类型的外部合作对象对创新绩效的重要性存在差异。研究发现,企业在创新实践中,内部R&D和纵向合作企业与横向合作企业知识搜寻之间存在互补协同的关系,但没有充分的证据表明内部R&D和大学/研究机构知识搜寻之间存在互补性。内部R&D和外部知识搜寻之间存在互补抑或替代的关系,主要受企业对外部知识吸收能力的影响。
The use of external knowledge to achieve innovation has become a common practice of our business innovation strategy. What is the relationship between internal R & D and external knowledge search? Will excessive external knowledge search weaken the strategic position of internal R & D? Based on the questionnaire survey data of 209 Chinese innovative enterprises, this paper analyzes the internal R & D activities and External knowledge search of the relationship between the empirical analysis. The results show that external knowledge search has an important impact on improving the innovation performance of enterprises, but the different types of external partners have different effects on innovation performance. The study found that in the practice of innovation, there are complementary synergies between internal R & D and vertical cooperative enterprises and knowledge search of horizontal cooperative enterprises, but there is not enough evidence to show the complementarity between internal R & D and university / research knowledge search. The relationship between internal R & D and external knowledge search is complementary or alternative, which is mainly affected by the enterprise’s ability to absorb external knowledge.
