中文摘要：

针对高技术联盟中日益突出的创新独占问题，通过对我国高技术行业的联盟企业276份有效问卷调查，探索双元导向创新独占机制对联盟绩效的作用机理。结果表明，正式化或非正式化导向创新独占机制都与联盟绩效间存在显著的倒U型关系，且双元导向创新独占机制对联盟绩效的影响优于单一导向创新独占机制的影响，同时，知识流动在双元导向创新独占机制及其交互项与联盟绩效的关系中均起了部分中介作用。说明适度的创新独占机制可以为联盟有效的知识流动创造一个信任、公平和政策透明的创新环境，进而提升联盟绩效，而且不同导向创新独占机制的作用存在差异。研究结果揭示了联盟中创新独占机制作用路径，为高技术联盟企业协调不同导向创新独占机制实践提供了指导。

英文摘要：

In high- tech alliance innovation appropriability problems have become more prominent, so we have surveyed the alliance companies of high - tech industries in our country with 276 valid questionnaires, and researched the function mechanism of dual orien- ted innovation appropriability mechanisms on alliance performance. As a result, both formal and informal innovation appropriability mechanisms have a significant inversed U relationship with alliance performance, and there are better effects of dual oriented innovation appropriability mechanisms on alliance performance than single oriented innovation appropriability mechanisms. Moreover, knowledge mobility partially mediates the relationship between formal or informal innovation appropriability mechanisms or their interactive item and alliance performance. It shows that moderate innovation appropriability mechanisms may create an innovation atmosphere with trust, justice and transparence policy for valid knowledge mobility, and then improve alliance performance, and it also illustrates that there are different effects between different innovation appropriability mechanisms. Our results reveal the function pathway of innovation appropriability mechanisms in alliance, which provide a guide for the high - tech alliance companies to coordinate different innovation appropriability mechanisms.
