Ant was suspended by the central government two days before its listing. The Wall Street Journal pointed out that it was a top-level decision. The public opinion community believes that it has something to do with Jack Ma's rhetoric in his speech. He has said he wants to use innovation to help solve China's financial problems, and criticized the government's tightening financial regulations for restricting technological development. As the "national teacher" of the Hong Kong government and an economist who has commented on current politics for many years, Lei photo background removing Dingming later wrote an article "The Ups and Downs of Ant's Listing", expressing support for the central government's strengthening of supervision: "It is impossible for Ant to be exempted from supervision. The government will not allow Ant. Engage dozens of times of leverage, otherwise, if something goes wrong, there will be a financial turmoil.” If you pay attention to Professor Lei’s consistent remarks [1] , you will find that his position has changed 180 degrees, completely contrary to what he has always advocated. The market is the most efficient, the so-called "big market, small government" neoliberal ideology. Four years ago, in an interview with Duan Media [2] , he said categorically that the core of the free market mechanism lies in the information that prices can provide. He believes that as simple as the production of pencils, there are complex and multi-level supply and demand relationships behind it, and each level of supply and demand knows how to use a simple message to decide what to do. That is the hand that virtually regulates the operation of the market - the price. Lei Dingming does not agree that the government's "visible hand" can be more impeccable than "price". "Experts in the planned economy cannot calculate the most suitable production volume with large computers, resulting in an imbalance between supply and demand."
