Abstract: This paper selects the indexes of currency position, securitisation rate, ratio of dependence on foreign trade, manufacturing ratio, foreign portfolio investment and others to do cluster analysis on the economic patterns of 9 countries by the clustering methods of system. The results were attained that the countries can be divided into three sorts of economies: USA and Britain belong to fictious economies because of their high currency position, securitisation rate and foreign portfolio investment; Canada, Germany and France belong to semi-fictious economies because their indexes are in the middle level, and Japan belongs to semi-fictitious economies because of its lower fictitious level but higher than semi-fictious economies; Russia, China, India and other developing countries belong to non-fictious economies because of their high ratio of dependence on foreign trade and manufacturing ratio. China has been the largest non-fictious economy. The paper provides the following suggestions: to maintain superior position of the real economy, to exploit funds and technology of fictious economies, to develop trade with semi-fictious economies, and to accelerate the transformation of economic development mode and the revision of industrial structure.
