Then, according to the current situation and evaluation results of Hainan marine intangible cultural heritage, the digital inheritance and protection path of Hainan marine intangible cultural heritage is designed by using modern technology as a means. Among the specific indicators of the endangerment evaluation index system of Hainan marine intangible cultural heritage, the economic benefit has the largest weight, which is as high as 0.104. It shows that the economic benefit of preserving and preserving Hainan marine intangible cultural heritage needs to be improved.
