Since China's reform and open door, the countries and regions of direct investment in China's mainland have been increasing. In 1995, the amount of foreign direct investment (FDI) in China was US$ 37.81 billion that was from more than 170 countries and regions. The regional structure of capital market of FDI in China has three characteristics: (1) The most of FDI was from the near countries or regions, Hong Kong Macao, Taiwan, Japan, South Korea, Thailand and Malaysia provided 80.3% of the amount of FDI in 1995. (2) Only several countries and regions provided most of FDI in China. (3) According to the contributory rate, the main capital market of FDI in China could be divided into four classes, including the guiding market, subsidiary market, new and development market, opportunity market. Most of FDI in China was from the developing countries and regions, which had a negative effect on the size and technical level of foreign capital enterprises. The author puts forward the countermeasures to improve the regional structure of capital market: (1) to keep the guiding market stable, (2) to open up chiefly the subsidiary market, (3) to guide actively the new and developing market, (4) to try hard to start the opportunity market.
