The proper use of Hong Kong and Macao laws and arbitration rules in maritime disputes has an exploratory role in the construction of a multi-dimensional maritime dispute resolution platform and mechanism in the Hengqin and Qianhai double cooperation zones，and at the same time helps to build an open and innovative bay area industrial system. This paper proposes to actively improve the diversified resolution mechanism for maritime disputes involving Hong Kong and Macao，and strengthen the cooperation between the Hengqin and Qianhai double cooperation zones and the Hong Kong and Macao Special Administrative Region in maritime dispute resolution，so as to better defend the legitimate rights and interests of maritime entities，promote the integrated development of the diversified resolution mechanism for maritime disputes and improve the market economic system as well as the modern social legal management environment.
