Not long ago, Jack Ma told Hainan's Communist Party secretary that it is necessary to transform Hainan Island into a huge smart city and pushing for the early stage of making it a "Safe City", "Cashless Payment Island" and "Smart Government". Anbound's research suggests that the goal of "cashless payment island" may be unsuitable. Cashless society appears to be a trend, but it involves the status of RMB in cash, the reunification of monetary policy, risk control and supervision and other issues. This target is suitable for Alibaba, but it may not be suitable for Hainan Province.
