The development of information technology，especially the new media，has had an indelible influence on the path and effectiveness of policy communication. Based on the study of 150 dispute policy events in 2016，this paper focuses on the impact of network disputes on the communication of public policy in the new media platform. The result shows that the dispute policy mainly involves the issues of social security，transportation，rule of law，education and environmental protection，etc.，most of which are complex. National issues are long-term and moderate；regional ones are short-term and intense. Micro blogging and WeChat show the range of the dispute，and the forum and the follow-up show the depth of the dispute，which means that the public and the media are the dominant forces in the dispute. The result of the dispute reflects the strong influence of the public policy “intervention”. The policy promulgation is the primary motive of the policy controversy；meanwhile，the interest demands，the dissatisfaction and the change of the policy are the main motive of participating in the dispute. In addition，the fundamental cause of the policy crisis does not point to the communication，but the imbalance of inherent social structure of the policy. The existing policy crisis is caused directly by the low policy and decision-making level. Accordingly，I put forward the daily communication strategy in response to the fundamental structural crisis，shallow procedural crisis prevention strategy，and the strategy against the superficial event crisis.
