基于2006-2011年四川旅游数据，用主成分分析、聚类和变异系数等方法，发现地震对国际旅游冲击大、恢复慢，国内旅游影响小且恢复快，原因在于国内外市场信息不对称。
Based on 12 data reflect tourism development indicators in the period from January 2006 to December 2011 in Sichuan Province,we use principal component loads to get the scores of tourism development,combined the K-means clustering with chart method to analysis the tourism development from macroscopic view;At the same time we use the mean,standard deviation and coefficient of variation to analysis Microscopic change rule of the tourism indicators.The results show that: ① From tourism development score,tourism industry in Sichuan province influenced by the 2008 5.12earthquake is quite huge,until 2011 year to return to the level of before earthquakes;②The international tourism in Sichuan province affected by 2008 5.12 sudden crisis events more serious;③ The domestic tourism in Sichuan Province affected by 2008 5.12 sudden crises smaller loss,and recover rapidly;④The international tourism influenced by sudden crises reflect a more sensitive,and the domestic tourism is less affected,with rigid characteristics of its development in the domestic tourism,the reason for this difference is the domestic and foreign markets exist information asymmetryphenomenon.
