Abstract: Can external R&D institutions ties facilitate enterprise innovation? To answer this question, this paper systematically studies the relationship between external R&D institutional ties, boundry-spanning search and enterprise innovation, combined with social network theory and innovation search theory. Empirical findings based on 270 manufacturing firms from China suggest that external R&D institutional ties can enhance enterprise innovation. Technology knowledge boundry-spanning search and market knowledge boundry-spanning search both play a full mediating role between external R&D institutional ties and enterprise innovation. External R&D institutional ties promote technology knowledge boundry-spanning search and market knowledge boundry-spanning search, and these two kinds of knowledge boundary-spanning search in turn enhance enterprise innovation. The study also indicates that the impact that external R&D institutional ties on technology knowledge boundry-spanning search is larger than that on market knowledge boundry-spanning search.

摘要： 外部研发机构联系能否提升企业创新？为了回答这一问题，本文结合社会网络理论和创新搜索理论，系统研究了外部研发机构联系、跨界搜索以及企业创新之间的关系。利用270家制造企业的研究样本进行了实证研究，结果表明制造企业与外部研发机构建立联系能够提升企业创新，技术知识和市场知识的跨界搜索在外部研发机构联系和企业创新之间起着完全中介作用。外部研发机构联系促进了技术知识和市场知识的跨界搜索，这两种知识的跨界搜索反过来增强了企业创新。研究还表明外部研发机构联系对技术知识跨界搜索的影响比对市场知识跨界搜索的影响更大。
