In the contemporary era, as competition among businesses intensifies, innovation and development in enterprise performance management are becoming increasingly crucial. Continuously enhancing employees' professional knowledge and skills not only improves their work capabilities but also boosts organizational performance, aiding companies in achieving sustainable development. Psychological capital, the latest theory in contemporary management science, transcends human and social capital, possessing characteristics of originality and forward-thinking. Managers, in their daily work, directly influence the attitudes and behaviors of their team members through formal or informal guidance and supervision. Creating a psychologically conducive environment, characterized by happiness, fulfillment, and belongingness, can positively and significantly impact managerial behavior, thus maximizing organizational effectiveness and managerial performance. Historically, businesses have prioritized employee performance management in human resources management processes, often neglecting the psychological needs of managers, thereby hindering the effective implementation of many incentive measures. Therefore, this study explores three dimensions of psychological capital and organizational performance, constructing a relevant structural equation model. By employing theoretical and empirical analysis methods, it validates the positive influence of psychological capital on organizational performance, providing insights into the impact of managerial psychological capital on organizational performance and actively contributing to the realization of corporate strategic objectives.
