This study approaches corporate governance from two perspectives—system and operation—through the mechanism of trust. In the current reality of increasing uncertainty, rapid technological change, and intensifying global competition, the issue of concentration of corporate ownership and control has a significant impact on top management's decision-making. Accordingly, top management requires the establishment of decision-making systems that can respond flexibly to external environmental changes. Furthermore, efficient operations are needed to minimize conflicting issues among the firm's stakeholders. These issues are directly linked to who substantially owns and controls the authority over decision-making. This study demonstrates how the trust mechanism influences corporate governance—minimizing problems that can arise from both institutional and operational perspectives. The trust mechanism does not remain at a single equilibrium point but dynamically gravitates toward equilibrium-based trust through desirable selection paths. This equilibrium-based trust serves as a driving force that significantly influences decision-making on the system side, while on the operational side, it performs the role of reducing internal control costs within the organization.
