摘要
SSM模型（偏离——份额分析）是区域产业分析的主要方法。四川旅游产业结构效益较差，主要原因在于结构非增长性部门占主导地位，餐饮、游览、娱乐、购物部门的竞争力较弱，发展速度不够，高附加值未能得以体现，影响了旅游经济的可持续发展。
SSM （ Shift - share Method） is a method of regional industry analysis. Sichuan tourism industry has the problem of low economic efficiency mainly because some structural non - growth sectors occupy dominant position in the industry. Such sectors as food, sightseeing, entertainment and shopping are lack of competitiveness and can＇t keep a high pace of development. Without high added value, these sectors actually affect the sustainable development of Sichuan＇s tourism economy.
