1. The main reason is that it is much more difficult to go public in China than in the United States. The IPO queue is too long for enterprises to wait, and the listing operation in the United States is more convenient and faster.

2. Most China companies listed in the United States have foreign-funded shareholders, such as venture capitalists, fund companies and investment banks, who want to list their companies in the United States. These shareholders hope that the company will comply with the regulatory policies of the US stock market, and it will be easier to realize the shares.

4. The American stock market has more relaxed listing conditions for high-tech enterprises. Some enterprises may not meet the listing conditions in China, but they can be listed in the United States.
