十年前净出口（出口减进口）占GDP 7%. 今天只占百分之二。而美国占其中的五分之一。也就是GDP的百分之零点四。所以贸易战对中国影响不应该很大。

Washington is a decade late in launching economic war on Beijing, says Andy Rothman, investment strategist at fund manager Matthews Asia. Net exports (the difference between exports and imports) account for just 2% of China’s gross domestic product, down from 9% in 2007. Sales to the U.S. account for a fifth of that. And most of the biggest exporters from China are foreign-owned multinationals. “The impact of a trade war on the majority of listed Chinese companies will be quite modest, because China is not an export-driven economy,” he says.
