Abstract: On the basis of economic location, question paper investigation, and a lot of statistical data, the Japanese investment enterprises (JIEs) and Korean-investment enterprises (KIEs) in China were studied. The paper discussed these issues: (1) the investment location behavior of the Japanese-capital enterprises and Korean capital enterprises in China; (2) the investment model of the JIEs and KIEs in China; (3) the space relation characteristic of the Japanese capital enterprises and Korean-capital enterprises in China. Base on the study, the authors come to the conclusion: (1) the main investment behavior of JIEs and KIEs in China is to reduce the cost. The Japanese-capital enterprises are even more interested in the Chinese market, i.e. the Japanese-capital enterprises are mainly “market-dimensional investment” and most of the Korean capital enterprises are “cost-dimensional investment”. (2) There are three kinds of investment models of JIEs and KIEs in China, that is the investment of exporting obsolete property, the exporting-replace investment, and the market developing investment. The KIEs mainly aim at the first and the second aspects. The JIEs aim at the second and the third aspects, especially the market developing investment. (3) It is dominant that the JIEs and KIEs have close production relation with the companies in their native country. But the relation with the Chinese enterprises is weak. R&D are chiefly conducted in their native country. When an enterprise carries out the R&D in China, the technology mainly comes from its native country. In order to suit the needs of Chinese market, some technologies have been reformed. At the same time, the staff training is also dependent on their native country. As for the market relationship, the sale market of the Japanese-capital enterprises is diversified by the different kind of product. Comparatively, the sale market of Korean-capital enterprises gives service to their native market mainly.
