Official media use, political participation, and government trust structure an empirical study based on the attitude of Chinese netizens

While research has explored the relationship between official media use and hierarchical government trust, there is a lack of studies that delve deeper into the relationship between official media use and government trust structure. Therefore, this study uses data from the 2017-2018 Chinese netizens' social awareness non-tracking survey and employs rational choice theory and process-based trust mechanisms theory to empirically explore, for the first time, the relationship between official media use and government trust structure, along with its underlying mechanisms. Government trust structure is divided into four categories based on the different levels of trust in the central government and local government: paradoxical government trust, equal distrust, hierarchical government trust and equal trust. Among them, hierarchical government trust can be divided into central-distrust-local-distrust, central-trust-local-distrust, and central-trust-local-trust. The study finds that although hierarchical government trust decreases, it is the dominant form of government trust structure, and central-trust-local-distrust is the dominant form of hierarchical government trust. The transformation of other government trust structures into hierarchical government trust of central-trust-local-trust is associated with official media use, and political participation has a mediating effect in official media use and government trust structure. Our findings not only deepen the understanding of rational choice theory and process-based trust mechanism theory but also expand the comprehensive understanding of government trust structure in authoritarian regimes like China.
