The financial integration between Zhuhai and Macao will bring a differentiated competitive advantage to Hengqin New Area and help Macao to further promote the development of financial technology. From the perspective of the financing market and the development of fintech companies, China is already in the leading position in the global fintech map. The development of Guangdong Province is prominent among all provinces and regions. Within the Greater Bay Area, in recent years, Macao has been actively exploring the development of financial technology, seeking in-depth cooperation with mainland financial technology companies, making breakthroughs in the field of electronic payments, and conducting in-depth exchanges in scientific research and innovation. At the same time, although there is still a gap in Zhuhai’s financial technology development compared with Shenzhen and Guangzhou, it still has great potential for differentiated development. At present, in order to promote the financial integration and development of Zhuhai and Macao, we are embarking on a path of integrated development of “finance + technology” in Hengqin. Looking ahead, it is recommended that interconnection should be made through financial technology to promote the development of financial integration between the two places. Specifically, it is suggested that Hengqin New Area should develop differentiated competition, focus on cross-border financial fields such as big data connectivity, and attract Macao’s financial technology resources. Create a financial technology industry fund to promote the development of crowdfunding, network investment and finance and other financial technology businesses. Set up financial technology laboratories for big data, Internet of Things, and blockchain to cultivate financial technology talents. Research and develop financial technology products and services in line with the characteristic financial development of Macao’s leasing industry. Macao should cooperate with leading financial technology companies in the mainland to vigorously develop financial regulatory technology.
