论文理论探讨并实证检验了企业竞争联系、合作联系对于知识转移效果的影响机理及作用差异，并进一步探讨了不同的制度支持因素对以上关系路径的情境约束机制。通过对我国404家企业的问卷调查，采用层次回归分析发现：竞争联系、合作联系对于知识转移效果均有正向促进作用，但二者效用无显著差异；此外，法律支持增强了竞争联系与知识转移效果的正向关系，相反却减弱了合作联系与知识转移效果间的正向关系；政治联系则正向调节了合作联系与知识转移效果间的正向关系。

This paper theoretically discusses and empirically examines the functional mechanisms of competitive ties and cooperative ties on knowledge transfer efficiency, their heterogeneities, and their contingencies upon institutional support as well. The hierarchical regression analysis, based on survey data from 404 Chinese firms, indicates that: both competitive ties and cooperative ties have positive effects on knowledge transfer efficiency, with no significant differences. Besides, legal support strengthens the positive relationship between competitive ties and knowledge transfer efficiency, but weakens the positive relationship between cooperative ties and knowledge transfer efficiency; and political ties positively moderate the positive relationship between cooperative ties and knowledge transfer efficiency.
