What are the advantages and disadvantages of building Hainan into an international tourist island?

The completion of the international tourist island will attract a large number of foreign capital into the province, and the tolerance of Hainan's land policy will certainly promote the development of Hainan's real estate industry. With the entry of foreign capital, it will create a lot of employment demand, solve the employment problem of Hainan people, improve people's income and further promote the balance between supply and demand on the island. The disadvantages outweigh the advantages: with the construction of an international tourist island, foreign capital and a large number of people from other provinces will flood into the island to invest in economic construction, and a large number of foreign things will inevitably affect the preservation and development of local culture. For example, the United States, after accepting a large number of immigrants from the world, has had an impact on its native American culture. The following ethnic problems and industrial competition will disrupt the original single local market. In stimulating competition, not everyone can retain the original pure essence, which will directly affect people's motivation to improve their own quality. In such fierce market competition, can people still follow the principle of fair trade?
