Based on self-determination theory and the "environment-cognition-behavior" analysis framework, harmonious work passion is introduced into the research system to systematically explore the mechanism and internal path of inclusive leadership on employees' creative territory behavior. Combined with work autonomy and status competition motivation, a three-way interaction model is constructed to reveal the boundary conditions under which inclusive leadership affects employees' creative territory behavior. Through situational experiments (Study 1) and multi-time questionnaire surveys (Study 2), the results showed that harmonious work passion mediates the negative impact of inclusive leadership and creative territory behavior; when work autonomy is strong and employees' status-competitive motivation is high, inclusive leadership has the most significant effect on creative territory behavior through harmonious work passion. The interaction among inclusive leadership, work autonomy, and status-competitive motivation is significant. The purpose of this study is to provide practical guidance for managers to reduce employees' negative behaviors by optimizing the work environment and incentive strategies.
