Abstract Based on evaluation model of order parameter and Internet governance tripartite collaboration，this study establishes the evaluation index system of Internet governance coordination degree, and then measures the coordination degree of Internet governance in the USA, United Kingdom, South Korea and China. Based on the Bayesian network, this study constructs the network of influencing factors of Internet collaborative governance and analyzes the reasons and the structural relationship of influencing factors. The results demonstrate that: although the degree of Internet coordination governance system in China is lower, the coordination degree of the government and the Internet media have advantages; the coordination degrees of the government and Internet users can promote the internet governance better，and improving the coordination of government and Internet users can promote the effectiveness of Internet collaborative governance better.
