In recent years，Guangzhou’s financial system has focused on the three major tasks of serving the real economy，preventing and controlling financial risks，and deepening financial reforms. It has made great efforts to improve the modern financial service system and achieved good results. There are also certain problems. Facing the new trend of the construction of the international financial hub in the Guangdong-Hong Kong-Macao Greater Bay Area and learning experience from expanding the financial opening-up in Beijing，Shanghai，and Shenzhen，Guangzhou should improve the modern financial service system，orderly promote the interconnection of financial markets，jointly build a platform for cooperation and development between Guangdong，Hong Kong，and Macao，and promote the construction of an international financial hub in the Guangdong-Hong Kong-Macao Greater Bay Area.
