The insurance industry is an economic booster and a social stabilizer. Exploring a new model of cross-border insurance services in the Guangdong-Hong Kong-Macao Greater Bay Area can actively implement the practical measures of the national strategic deployment，effectively strengthen the foreign exchange management of cross-border premiums，and at the same time promote the better integration of Hong Kong and Macao compatriots into the needs of the development of the Bay Area. This kind of service can effectively curb the development of “illegal insurance” and accelerate the in-depth integration of Guangdong，Hong Kong and Macao，which is of great value and significance. In order to better protect the rights and benefits of policyholders and minimize risks，cross-border insurance services are recommended to gradually expand the scope of pilot projects，to operate closed capital channels and at the same time to construct perfect audit mechanism.
