中文摘要：

旅游产业脆弱性是旅游可持续发展的反向。研究运用主成分分析法，采用5级分类，从外部旅游环境脆弱和内部旅游结构脆弱两个方面，对我国旅游产业脆弱性进行了综合测度。结果显示：①中国旅游产业处于中等脆弱水平，但分布极不均衡。②当前，旅游结构性脆弱是影响我国旅游产业脆弱性的根源性原因。③中国旅游产业高度脆弱省区主要集中在西部，其旅游环境脆弱性是旅游产业脆弱性的主要来源，影响旅游产业脆弱性的主要是生态经济因子和旅游风险因子；旅游产业中度脆弱省区，呈分布散、分布广、差异大特征，影响旅游产业脆弱性的主要是服务效率因子、旅游市场化率因子和旅游投资协调平衡因子；旅游产业轻微度脆弱省区主要集中在东部，其旅游结构性脆弱性是旅游产业脆弱性的主要来源，影响旅游产业脆弱性的主要是旅游投资协调平衡因子。

英文摘要：

Vulnerability of tourism is the reverse force of sustainable tourism development. The purpose of vulnerability research is to achieve sustainable development by means of reducing system vulnerability. Principal components analysis and the way of five-level classification are involved in this research. Three important findings can be obtained as follows. （1） China＇s tourism industry is at the medium level in vulnerability; however, it is not evenly distributed. The tourism industry of southeast coastal provinces shows a relatively low level in vulnerability compared with the other two regions. （2） On the whole, China＇s tourism structure fragility is more serious than tourism environmental vulnerability. Structural vulnerability and environmental-stress vulnerability are prone to occurrence with the effects of related incentives. （3） Provinces in westem China have high vulnerability in tourism industry, where the environmental vulnerability of tourism is the main cause for vulnerability of tourism industry, while ecological economic factors and tourism risk factors are the major influencing factors of vulnerability of tourism industry. The provinces with medium vulnerability in tourism industry are distributed widely and differently, where the influencing factors of vulnerability of tourism industry include service efficiency, tourist market rate, tourism investment coordination and balance. The vulnerability of tourism industry in eastern China is relatively slight, where the structural vulnerability of tourism is the main cause for vulnerability of tourism industry, while tourism investment coordination and balance are the main influencing factors of vulnerability of tourism industry.
