Hainan is the largest special economic zone and the only tropical island province in China. Its unique advantages in island tourism resources and years of development and construction have made it a popular tourist destination for domestic and foreign tourists. Understanding the relationship between tourism revenue and the number of people in the host countries is an important reference for formulating targeted tourism strategic development plans. This paper uses the 2015~2019 tourism related data in Hainan Province as a sample, and uses the gray relational analysis method to verify the correlation between tourism revenue and the number of tourists received from major countries. The quantitative analysis of the relationship between the tourism revenue and the number of tourists in major countries from a systematic perspective has certain practical significance for the future development of the tourism industry in Hainan Province.
