国际资本流动包括直接投资、证券投资和其他投资(主要是银行贷款和官方资本流动)流动三种主要形式。而发达国家之间的资本流动,又不同于发达国家同新兴市场国家间的资本流动:前者是国际资本流动的主要力量,而后者发展很快,但波动大。发达国家间的资本流动主要是美国、欧洲和日本三大经济区间的流动。 International capital flows include the three main forms of direct investment, securities investment and other flows of investments (mainly bank loans and official capital flows). The capital flow between developed countries is different from the capital flows between developed countries and emerging market countries. The former is the main force of international capital flows, while the latter develops rapidly but fluctuates greatly. Capital flows among developed countries are mainly the three major economic zones in the United States, Europe and Japan.
