The 2019 Qianhai Cooperation Forum, co-sponsored by the Shenzhen Qianhai Administration and the National Hong Kong and Macao Research Association, was held recently. Ma Weihua, chairman of the National Science and Technology Achievements Conversion and Guidance Fund and former president of China Merchants Bank, said that Qianhai, as a bridge connecting Guangzhou, Shenzhen and Hong Kong, is a bridge between Guangzhou, Hong Kong and Macao, and has the advantage of developing a 'financial + technology' industry. If the two are combined, it will promote the agglomeration, development and upgrading of the Dawan District industry. How to achieve it? First of all, we must use technology to promote the new business of Qianhai Finance. At present, Qianhai is dominated by traditional financial formats, and needs to promote its transformation and upgrading through cloud computing, big data, artificial intelligence, and blockchain.
