Abstract: 【Purpose/significance】Exploring the symbiotic relationship and mechanism between network public opinions and analyzing
the important links in the symbiotic effect are helpful to enhance the government's ability to respond to and guide network public opin‐ions【. Method/process】Based on the symbiosis theory in nature,the mechanism of symbiosis effect was analyzed from the three impor‐tant factors of symbiosis public opinion:qualitative parameter compatibility,development level and development potential.A symbiosis model based on Logistic was put forward.Combined with the life cycle theory,the simulation experiment was conducted to explain the influence of symbiotic effect on symbiosis public opinion and its influence path. The symbiotic model is validated in the empirical analysis【. Result/conclusion】Based on the simulation experiment and analysis results of the symbiosis model,the ideas and strategies of eliminating the negative influence of network rumors and enhancing the positive influence of positive public opinions were proposed by elements and stages.The good fit between the model and the actual data also indicates the reliability and effectiveness of the model.【Innovation/limitation】On the basis of in-depth research on the symbiosis mechanism of public opinion,a logistic symbiosis model is proposed and simulation analysis and empirical test are carried out.However,the applicable scope of the model is limited to the symbio‐sis of public opinion.
