Grey Relational Analysis of Tourism Industry

It is well known that the development of tourism is influenced by many factors, however, how to determine the factors and evaluate the influencing degree is an important problem. Most of the study used statistics method to calculate, and this paper proposed a different way - Grey Relational Analysis. This paper selected 2 indexes as original reference sequence, and 10 factors in tourism industry development as sequences for comparison to analysis the influencing factors in the development of tourism industry. Then the model to identify the influence degree of factors based on GRA was proposed. The result is that the top five influencing factors are numbers of domestic tourism, per capita GDP, added value of the tertiary industry, gross domestic product, and urban disposable income. The GRA is an effective way to assess the impact of different factors on the development of tourism industry and provides a good tool for decision makers and researchers for further study.
