Evolution mechanism and influencing factors of multidimensional public opinion dissemination from the perspective of game theory

With the popularization and development of the Internet, in-depth investigation into the evolutionary mechanism of online multidimensional public opinion dissemination is crucial to modern public opinion management. This study introduces game theory into the analysis of the driving mechanism and propagation law of online public opinion, constructs a multi-dimensional public opinion network model covering social, psychological, viewpoint and environmental dimensions, and combines systematic simulation and empirical analysis. The study found: (1) In the process of online public opinion communication, the activity level of micro individuals is influenced by the comprehensive benefits of the game. The game benefits are internally affected by the benefits of publishing and receiving public opinion, and the cost of publishing public opinion. Externally, they are affected by the trust between opinion leaders; (2) Increasing the costs of publishing public opinion can effectively reduce the proportion of active participants in public opinion. Increasing the benefits of receiving or publishing public opinion will increase the proportion of active participants in public opinion; (3) A higher average social bandwagon accelerates the polarization process of viewpoints in the spread of online public opinion, while a higher average social trust slows down the speed of viewpoint polarization in the spread of online public opinion. An unfavorable external environment helps promote the polarization of viewpoints in the spread of online public opinion. This study provides a new perspective for understanding and predicting the dissemination of online public opinion, and a scientific basis for the government to formulate effective online public opinion management strategies.
