Abstract: Combining the characteristics of reverse internationalization enterprises, and deconstruction of the innovation search strategy from two dimensions (network embeddedness and knowledge source utilization), this paper explores the different influences of two balanced innovation search modes (home-focuesd and foreign-multi search, home-multi and foreign-focused search) on organizational ambidexterity through strategic fit theory, and the moderating effects of decision rationality (causation and effectuation). In this paper，the multiple regression method is used to test the data of 245 enterprises. It is found that: (1)both of the two balanced innovation search modes promote organizational ambidexterity; (2)causation and effectuation have weakening effects on the positive relationship between the home and abroad cross-search balance and organizational ambidexterity; (3)the integration of causation and effectuation has a positive moderating effect on the relationship between |HM-AF| and organizational ambidexterity, but only positively strengthes the effects between |HF-AM| and integration level of ambidexterity. This research further deepens the understanding of the mechanism of innovation search balance on organizational ambidexterity based on decision rationality theory, and provides a new way of thinking for the innovation practice of reverse internationalization enterprises.

摘要： 结合逆向国际化企业的特征，从网络嵌入和知识源利用两个维度解构该类企业的创新搜索策略，并结合战略匹配理论探讨了两种创新搜索平衡模式（国内聚焦和国外多源搜索、国内多源和国外聚焦搜索）对组织双元性的差异性影响，以及因果与效果推理在其中的调节效应。采用多元层次回归的方法对245家企业问卷数据进行实证检验，研究发现：（1）两种搜索模式对组织双元性都具有正向影响；（2）因果推理和效果推理均负向调节上述关系；（3）整合因果和效果推理能够增强国内多源和国外聚焦搜索平衡对组织双元性的影响，而对国内聚焦和国外多源搜索平衡与双元性的正向调节作用仅得到部分验证。研究结果进一步深化了整合决策理性作用下创新搜索平衡对组织双元性构建的作用机理的认识，为逆向国际化企业创新实践提供了新思路。
