摘要：在新一轮科技革命与全球经济新常态的百年未有之大变局下，我国企业正面临着由贸易之争转变为科技实力之争所带来的“卡脖子”技术困境。本研究以半导体芯片产业企业专利为研究样本，实证分析了技术重组与跨界搜索对企业关键核心技术创新的影响，以期助力突破“卡脖子”技术。研究发现：企业重组企业开发的技术有利于关键核心技术创新，但重组高校和科研院所开发的技术未能促进企业关键核心技术创新，说明企业吸收高校和科研院所知识的能力仍然较弱。进一步研究发现，跨界搜索在重组企业开发技术与关键核心技术创新之间起到了锦上添花的“助力效应”，但是在重组高校开发技术与关键核心技术创新之间起到了“放大效应”，即跨界搜索放大了高校开发技术的阻碍作用。本文结果表明，不同创新主体开发的技术对企业关键核心技术创新产生了截然不同的作用效果，对如何实现创新链良性耦合提供了微观证据，为后续“卡脖子”关键核心技术攻克提供了经验支持。

Abstract: Under the unprecedented changes of new round of technological revolution and the new state of global economy, firms in China are facing "neck-jamming" technology dilemma brought by the transformation of the competition of trade into technology strength. Our study empirically analyzed the impact of technology recombination and boundary-spanning search on the KCT innovation of focal enterprises in order to promote the breakthrough of "neck-jamming" technology, taking the patents of semiconductor chip as the research sample. We found that recombining firm-developed technology has positive effect on KCT innovation, while recombining university-and institute-developed technology has opposite effect. Further results indicated that the boundary-spanning search played a "booster effect" between the firm-developed technology recombination and KCT innovation, but played a "magnifying effect" between the university-developed technology recombination and KCT innovation. The results showed that the technologies developed by different innovation entities have different effects on the KCT innovation, which provides micro evidence on how to achieve benign coupling of innovation chain as well as empirical support for the subsequent "neck-jamming" KCT breakthrough.
