Coaching leadership, as a leadership style that emphasizes empowerment, developing the potential of subordinates, and promoting continuous learning, has gained increasing attention from both the academic and practical communities in contemporary complex organizational environments. This research focuses on exploring the complex dual effects of coaching leadership on employees' behavioral performance, particularly its crucial change-oriented behavior that is essential for organizational change, as well as the unethical behaviors that potentially undermine the foundation of organizational ethics. This research constructs and validates an integrated theoretical framework, aiming to systematically reveal the key mediating effect of knowledge sharing between coaching leadership and the aforementioned two types of behaviors, as well as the important moderating role of social capital. This research is based on leadership theory, social exchange theory, and conservation of resources theory, and constructs an integrated model with mediating and moderating paths. It systematically examines the internal effect of coaching leadership on influencing employees' change- oriented behavior and unethical behavior through knowledge sharing, and further explores the boundary condition role of social capital in this process. Specifically, the research suggests that coaching leadership, by fostering a trusting and open communication environment, can effectively enhance the knowledge-sharing behavior among employees. This sharing behavior not only helps employees acquire diverse perspectives and experience resources, thereby enhancing their ability and willingness to drive change, but also may reduce the occurrence of unethical behavior by strengthening the sense of norms and responsibility. Furthermore, knowledge sharing is regarded as an important mediating variable connecting leadership behavior and employee behavior, and is a crucial psychological path for understanding the relationship between the two. Furthermore, the research incorporates social capital as a moderating variable, emphasizing its role in shaping the relationship networks, trust, and normative environment among organizational members. When there is sufficient social capital within an organization, the positive impact of coaching leadership is more likely to be amplified. The support and cooperation advocated by this leadership style are more easily disseminated within the organization, thereby further strengthening employees' change-oriented behavior, and more effectively preventing the occurrence of unethical behavior. In other words, social capital plays a crucial enhancing role in the path by which leadership influences employee behavior, and is an important contextual factor for achieving good organizational behavior. This research rigorously conducted empirical analysis to verify the core proposition and made theoretical contributions in three aspects: Firstly, it broke through the focus of existing literature on the positive effects of coaching leadership, and for the systematically revealed its potential impact on unethical behavior, deepening the understanding of its duality; Secondly, it revealed the dual roles of knowledge sharing in the leadership effect, clarified its mediating role in both positive and negative effects, and enriched the understanding of its complex functions; Thirdly, it innovatively introduced social capital as a moderating variable, revealing its dual role in strengthening positive behaviors and amplifying ethical risks, and expanding the contextual perspective of leadership and organizational ethics research. At the practical level, this research emphasizes that organizations should focus on shaping a coaching leadership culture, fostering an atmosphere of knowledge sharing, and enhancing the accumulation and utilization of social capital, in order to create an efficient, ethical, and change-oriented organizational environment.
