On January 12, Tencent Technology said, by quoting a source close to the shared OFO company, that on January 10 after the payment of staff salaries and other settlements, only less than 600 million yuan is available in OFO's accounts.If calculated according to monthly salary of OFO personnel of 400-500 million yuan and various operating costs and other expenditures, as well as the continued outflow of the deposit, OFO's cash can only support one month.With another shared bicycle company, blue bicycle, was exposed of dissolution and difficulty to return deposit to users in November last year, it is clear that the bicycle sharing industry has faced the pressure of life and death. For bicycle sharing giants such as Mobike and OFO, which cover a large area and have a large number of bicycles, the cost of manufacturing alone requires tens of billions of funds. With the increase in amount of bicycles, the daily operation and maintenance costs will also continue to increase, which requires more capital investment. And on revenue side, the industry is fiercely competitive, and the price has been lowered to 1 hour 1 yuan or less, so itseems that it is not possible to gain profit by user riding incomeTherefore, many shared bicycle companies have to consider making profits by embezzlement of deposit and deposit fees, but this clearly runs counter to integrity and regulatory purposes. Considering again the huge number of shared bicycles damaged and abandoned at present, it has obviously caused a lot of waste of economic resources and environmental problems. Last year, a research team had judged that sharing a bicycle was not only an "idiot economy" but also a "fraud economy" and forecasted that more and more shared bicycle companies would collapse. Although shared economy is an innovation, the shared bicycle profit model is still very vague. At present, it is necessary to find an efficient, sustainable and green economic model for sharing.
