Abstract: Organizational health is an important guarantee for an enterprise to keep its foundation in the long run. However, most enterprises pay too much attention to economic goals and efficiency in the process of development, without regard to the sustainable growth and balanced development of the organization, which leads to the frequent occurrence of unhealthy “symptoms” of the organization. As the status and influence of Chinese unions continue to rise, the establishment of enterprises-union coupling relationship will help enterprises break through their cognitive limitations and effectively observe, explain and allocate organizational attention, thus maintaining growth vitality and adapting to environmental changes. However, the existing theoretical clues about the impact of enterprise-union coupling relationship on organizational health are not consistent, and it is urgent to further explore how different enterprise-union coupling relationship (EUCR) affects organizational health differently.Based on the attention-based view, this paper explores the differential effects of Borderline-, Auxiliary-, Rectification-, and Symbiosis-EUCR on organizational health. A two-time point questionnaire survey is conducted to collect 609 enterprise/union managers’ data. K-means method is used for cluster analysis and relevant hypotheses are tested. The results show that: (1) Characterized by “loose coupling”, Borderline-EUCR has a negative effect on organizational health. (2) Characterized by “production coalition”, Auxiliary-EUCR has an inverted U-shaped first-positive-then-negative effect on organizational health. (3) Characterized by “competition and balance”, Rectification-EUCR has a U-shaped first-negative-then-positive effect on organizational health. (4) Characterized by “value co-creation” and “benefit sharing”, Symbiosis-EUCR has a positive effect on organizational health. Compared with other models, the Symbiosis-EUCR is more effective in improving organizational health in the context of Chinese organizations.The results reveal the mode characteristics of the Borderline-, Auxiliary-, Rectification- and Symbiosis- EUCR and its differential impact on organizational health, which not only provide a new theoretical perspective for the research on the antecedents of organizational health, but also enrich the research on the impact of the EUCR in China. In the practice of organizational management, enterprise and union need to choose appropriate evolution strategies to promote the transition from Borderline-, Auxiliary-, Rectification- EUCR to Symbiosis- EUCR, which is more conducive to the realization of comprehensive, coordinated and sustainable organizational health.
