Simulation and Demonstration of Financial Network Public Opinion Evolution Mechanism
The aggregation model of financial network public opinion is constructed and the simulation is carried on.On the basis,taking the 2020"US stock circuit breaker"as a real case to test the aggregation process of financial network public opinion,and describing the evolution mechanism of financial network public opinion,it is finds that:first,in the simulation environment,the greater the individual acceptance,the faster the aggregation rate of public opinion willbe.The greater the trust threshold,the more easily the views in the network tend to be consistent.The strong relationship between individuals can promote the aggregation of public opinion in the financial network better.Second,the case demonstrates that the exchange of opinions among individual investors is conducive to the aggregation of views,but there are still poles in their views based on negative and positive emotions.And the strong relationship between individual investors and mainstream financial media can accelerate the evolution of financial network public opinion.The results are of enlightening significance for improving the supervision of public opinion on the financial network in China.
