This paper presents and analyzes an analytical model of the stock market’s complex network structure, based on the Chinese stock market of the financial industry. Firstly, according to the correlation coefficient formula, we will calculate the correlation coefficient between the stocks by using the stocks data obtained, and we do a quantitative analysis to select the appropriate threshold to filter out low directed correlation numerical value, on this account we establish a stock market’s complex network; then using the centrality analysis methods to analyze the stock market’s complex network structure, from degree centrality, betweenness centrality, closeness centrality of three aspects to make an analysis, in order to study promoting effects of the leading stocks in the financial industry; and finally we analyze the small-world network characteristics of the stock network established, drawing the conclusion that the small-world network characteristics of the stock network is obvious.
