Chinese leaders including Xi Jinping have frowned on the accumulation of wealth and the IPO pay day, says this report in the WSJ. The largely unregulated company Alibaba in its role as a financial business, its complex ownership structure, and practices, have met with skepticism from China's financial regulators. They see the financial operations of Alibaba and its businesses as operating with little financial oversight and the state having to assume risks if something failed. The company's business model of payments app Alipay, mutual fund, voluminous data collection, operations as small loan provider to half a billion people, are seen by Chinese leaders and president Xi as posing unknown and unclear risks when not properly regulated. Commercial banks are subject to  tough regulations and capital requirements that Alibaba has avoided. State owned banks supply Alibaba with majority of the funding and take on most of the risk even though Alibaba makes profit from the transactions, is the perception of regulators. China's export model and manufacturing have enable it to create the banking capital on which such internet business models have thrived. In a world where supply chains are being redone, and following the pandemic, there are questions about how businesses that were created in the period before the pandemic should operate in a different environment. ...

China's leaders including president Xi Jinping, and China's financial regulators have frowned on the lack of regulation of the financial businesses of Alibaba. They see the state banks which are highly regulated with capital requirements as supplying the capital on which Alibaba makes a profit on transactions, yet having to take on the risks if something was to fail. Alibaba itself has avoided the financial regulation needed for stability in its rush for growth. At one point says the WSJ, Xi and other leaders were infuriated and decided to halt the Ant initial public offering that would provide accumulation of wealth and a pay day while increasing risks in the financial system for China.

China has seen novel uses of the internet. Pinduoduo is one of them. It brings people together on the internet to socialize and shop together. Purchases are small compared to Alibaba- $324 a year on average. By  bringing people in large numbers it has brought in about 788 million users in 2020.  One of the attractions is an orchard game where people tend to their digital orchards to earn shopping vouchers and prizes such as boxes of mangoes.The founder Mr. Huang studied computer science at the University of Wisconsin- Madison where he met Chen who now runs the company. Huang's first effort as recently as 2015 was to sell lychees and fruit from their sole warehouse in Shanghai on WeChat platform. This failed when the computer systems of the website could not handle the large number of orders. Lychees then rotted at the warehouse. From that first effort he realized the way social and browsing platforms could work with shopping. To build up large number of buyers who could be served advertising he came up with subsidies to buyers that are financed from the advertising. Money from advertising is put back into the subsidies. The buyers get discount on purchases and the browsing social platform builds large number of users in a short time. In this way it has as many users as Alibaba but purchases are small.  As in these types of startups with huge valuations and fast growth no profits were made in 2020. The loss is $1.1 billion in 2020. It has put $13 billion of the ad revenues into subsidizing the products on the site. Investors have given the company $6 billion for an agriculture program to sell fresh food and produce.  The Chinese government sees the company subsidies as having an effect of distorting the market prices. Regulators have fined the company for its practices. The company's working culture has some aspects that come under criticism with deaths of two employees.  This offers a glimpse of China's internet culture. How much of it is real constructive development of the internet is always a question. Is investor capital productively invested is also a question. Like Japan in the late 1980's few questions are asked by investors about productive uses of capital. As growth slows as it did in Japan by 2000 a lot of these questions are likely to come back.   ...
