This paper has researched the leading-nodes fluctuation of the CPI (the consumer price Index) based on Complex Network. At present, the trend of Chinese economy further consolidate, and controlling inflation expectations become a new focus. The price fluctuations of consumer often affect each other. However, in a number of fluctuating commodity prices, there are several products play an important role on effecting the rest commodity price changes.The paper Selected representative commodities included in Guangzhou CPI as nodes, on the basis of time Series of above commodities prices indexs from 2001 to 2009, researched correlation coefficients p of time series between any two, when p — 0.3, the two nodes was connected. The authors established price fluctuation weighted complex network to study the complex relationship of commodity price fluctuation. By searching for the leading commodity goods (i.e. leading node) from a number of goods, the authors proposed to monitor of these leading commodities, it will play an important role in controlling the whole consumer price changes and establishing a price mechanism on emergency management.
