Abstract The authors propose a method to extract individual travel spatiotemp­oral behaviors from social media data, and then mine the group based on massive spatiotemp­oral behaviors. This study collects more than 40 million global geographic microblogs from users who have visited Suzhou, extracts 88270 tourism trajectori­es, and identifies 36 classes of inter-city tourism movement patterns in five categories. It is found that the extracted patterns conform to the LCF theoretica­l model; besides the simple movement patterns, there are more complex composite movement patterns. Based on big data, more accurate tourism movement patterns can be obtained, which helps tourism managers understand tourists’ trends and preference­s, adjust destinatio­n marketing strategies, optimize tourism resource allocation, and provide better services for tourists. Key words tourism movement pattern; social media; geographic big data; LCF model
