After this research on the present situation of Hainan's catering industry, we can draw the following conclusions: (1) The layout of the catering industry is all in the central city of the city or in popular areas, and the huge consumer groups are conducive to the development of the catering industry. Often, the catering industry in these areas will be prosperous and the number of tourists will continue, especially during holidays or several golden weeks. ⑵ In the layout of the catering industry, all kinds of distinctive cuisines need to be composed together to meet the needs of different consumers. Flavor food in different places provides consumers with the opportunity to choose. If only a few hotels participate in the competition, the development will certainly not last long. ⑶ There are differences in the composition of catering industry in different functional areas: hotels in urban business districts will focus on high-end consumption in consideration of the needs of most high-end consumers, while those near schools will consider the situation of students and provide cheap catering services. ⑶The catering industry in Hainan has developed rapidly in recent years, except for a large number of local cuisines and overseas cuisines, and its functions are constantly improving and growing.
