Abstract: The paper analyzes the sequence scale difference of the five-star hotels in the Belt and Road key provinces using the data from 2000 to 2014. The research found that:①The five-star hotels of the Belt and Road key provinces is in a growing trend. Its overall development is not balanced and the first distribution is obvious.②After double logarithm regression analysis, the size of the five-star hotels of the Belt and Road key provinces is in the distribution of the rank and evolving from the single fractal to the double fractal. The change of homogeneous parameter q value shows that the distribution of them transformed from centralized to the first type. The gap between the ideal K and the actual K shows that the region's five star hotel still has potential for development in the future.③The five-star hotels of the Belt and Road key provinces presents four types: stable type, fluctuations type, ascending and recession type. Causes affecting the five-star hotels of the Belt and Road key provinces are analyzed from the aspects of tourism resources endowment, transportation infrastructure, economic development level, the degree of openness and the tourism development level.

摘要： 本文选取“一带一路”重点省区2000—2014年五星级酒店的数据，分析了该区域五星级酒店的位序规模差异。研究发现：①“一带一路”重点省区五星级酒店处于不断增长的发展态势，其整体发展不平衡，首位分布明显。②双对数回归分析发现，“一带一路”重点省区五星级酒店呈位序规模分布，并由单分形向双分形演变；齐夫参数q的变化表明其分布由集中型向首位型发展；理想K值与实际K值的差值变化表明未来该区域五星级酒店仍具发展潜力。③“一带一路”重点省区五星级酒店呈现平稳型、波动型、上升型和减速型四种形态，并从旅游资源禀赋、交通基础设施、经济发展水平、对外开放度和旅游发展水平等五个方面分析了影响其发展态势的原因。
