On September 4, the first Guangdong-Hong Kong-Macao Greater Bay Area Low-Altitude Economy Symposium (Guangzhou) was held. At the meeting, Yangxi, member of the Party Committee and Deputy General Manager of Guangdong Airport Management Group Co., Ltd., and Chairman of the Guangdong-Hong Kong-Macao Greater Bay Area Low-Altitude Economy Industry Alliance, stated that from the perspective of the current development, integration, and radiation radius of the low-altitude economy in the Guangdong-Hong Kong-Macao Greater Bay Area, the Greater Bay Area has gradually formed two "low-altitude economic cross-belts": one is the productive financial service belt with Hong Kong, Macao, and Shenzhen as the core; the other is the production and manufacturing service belt with Guangzhou, Zhuhai, and Foshan as the core. With the joint and deep expansion of these belts, a highly extendable "low-altitude economic circle" has been formed. (Securities Times)
