This study focused on the analysis of causal relationship between the factors of ownership of enterprises and the period of managers' tenure, focusing on China's listed enterprises. It is true that research on the impact of the characteristics of management entities represented by managers, board members, etc. among the factors of corporate governance on the period of management has been relatively active, while there has been little research on the causal relationship of corporate-owned entities, which can be seen as another key entity, to the period of management. Thus, in this study, the characteristics of major shareholders, institutional investors, and ownership types (whether public or private enterprises) that can be classified as the factor characteristics of the ownership principal of major enterprises in China were presented as independent variables, and the effect of these factors on the length of management tenure was analysed in a comprehensive manner. The empirical study was conducted through a fixed effect model, utilizing a series of 3480 data from a total of 435 Chinese listed companies over eight years from 2009 to 2016. The independent variables have established the share of institutional investors, the share of ownership of the entity's key investment entities, the degree of concentration of ownership by major shareholders who account for a significant portion of the ownership interests, and the type of ownership that determines whether a public or private entity is in office, each of which has been verified for its impact on the length of the management's tenure. In addition, it was confirmed that the type of entity's ownership has an interaction effect in the relationship between the institutional investor's equity ratio and the period of management's tenure, the concentration of major shareholders' ownership and the period of management's tenure. The analysis showed that institutional investors' equity ratios had a significant positive relationship with the manager's tenure. However, the interaction effect of ownership types on the causal relationship between these two variables was not significant. On the other hand, the ownership concentration of a major shareholder and its relationship with the manager's tenure have been verified not only to have a significant positive effect, but also to the relationship between the two variables, the ownership type has a significant wealth adjustment effect of wealth (-). These analysis results suggest that in practice, the characteristics of the owning entity may be considered as factors affecting the length of the management's tenure, and that the dynamics of these factors may be considered in the selection, management and maintenance of relationships of the owning entity of the entity. In addition, it would be meaningful in that it is theoretically an empirical study that fills the gap between the characteristics of ownership subjects, the period of management tenure, and the research on corporate governance for Chinese companies, which was relatively lacking in the research related to the period of management.
