中文摘要：

选取西安和成都两个西部典型旅游城市为样本，借鉴物理学耦合协调度函数，建立入境旅游流与星级饭店的耦合度模型和协调度模型，研究两城市入境旅游流与星级饭店的耦合状况，对其进行定量对比分析，探寻入境旅游需求与饭店供给的内在关系、耦合协调时序演变规律。研究发现，利用耦合协调度模型可以较好地评价两者的耦合协调状况；西安、成都的入境旅游流与星级饭店综合发展水平总体呈上升态势；两城市的入境旅游流与星级饭店系统协调度都经历了从失调到协调的演变过程，成都两系统的耦合协调度低于西安；大事件对于入境旅游和饭店业的发展都有明显的影响。

英文摘要：

Selecting two typical tourism cities Xi＇ an, Chengdu as sample cities and using the physics coupling coordination degree function, this paper established the coupling degree model and the coordination degree model of inbound tourist flow and star hotels to study the coupling conditions of inbound tourist flows and star hotels of the two cities and carried out the quantitative analysis to explore the internal relationship between inbound tourism demand and hotel industry supply and coupled timing coordination evolution. The results showed ： Coupling coordination degree model could be used to evaluate the coupling coordination condition of the two, the inbound tourism flows and the comprehensive development level of star hotel of Xi＇ an and Chengdu showed an overall upward trend, the system coordination of the inbound tourism flow and star hotel of the two cities all experienced the process from imbalance to the coordination, and the coordination degree of Chengdu was lower than that of Xi＇ an. Big events had obvious influence on the inbound tourism and hotel industry.
