美国是目前世界上最大的资本市场。中国企业的海外上市，选在美国有许多优点：一是资金供应充足，仅美国的工会基金到今年２月份就达４．８万亿美元，而且美国证券市场上还活跃着很多外国投资资金；二是美国公司、投资人愿意投资于处于相对发展的早期的公司，特别是各式各样的? The United States is by far the largest capital market in the world. The overseas listing of Chinese enterprises and their election in the United States has many advantages. First, the capital supply is sufficient. Only the U.S. union funds reached 4.8 trillion U.S. dollars in February this year, and many foreign investment funds are still active in the U.S. securities market. Second, are American companies and investors willing to invest in early-stage companies that are relatively developing, especially in all kinds?
