Professor Zheng believes that Hainan's development must be integrated with the GBA. By leveraging its comprehensive comparative advantages, Hainan should connect with the socio-economic activities of the Greater Bay Area, enabling greater flow and interaction with the region. With the core of the service industry lying in its various rules and regulations, Hainan should learn from Hong Kong's regulatory frameworks across various sectors to develop its service industry. In terms of attracting and utilizing foreign investment, the Hainan FTP should connect with the vast market of mainland China and the ten member states of ASEAN. Through these "two connections," Hainan can create profitable opportunities for businesses, establishing itself as a prime destination for foreign investment.
