Based on the former two phenomena, public marketing of tourism destination and SNS communication are with integrative relationship, which means three points: SNS is the environment of destination public marketing; the value of public marketing is the value guidance of SNS communication; communication effect is the strategic basis of implementation of destination public marketing in social networks.Based on the Sina Weibo platform for data collection, taking Gangwon in South Korea and Singapore as destination cases, this article collected the micro blog in Sina Weibo as text, refined the theoretical model of SNS communication effect by grounded theory. On this basis, this paper defined the relevant variables through the literature review, collect the data through the questionnaire survey, verified the theoretical model with the measurement of reliability test, validity test and SEM. Then, the hypotheses testing results and analysis have been put forward.The promotion strategies and tactics are suggested around the communicators, audience and communication path in SNS communication.
