Abstract��
According to the trade data of global construction machinery products published by UN COMTRADE from 1992 to 2011, this paper used the analysis method of complex network to calculate such weighted-less and weighted complex network properties as the density, node strength, clustering coefficient, heterogeneity, core-periphery structure and analyzed its evolution properties. The study shows that, the network��s density and node strength is increasing year by year (except the large fluctuations caused by the economic crisis), the trade relations have shown a pattern of diversification, the core degree of the US is declining during the nearly twenty years, while China, which is one of the emerging economies, its core degree has been rising during the time.
