【摘要】:運(yùn)用復(fù)雜網(wǎng)絡(luò)方法,構(gòu)建商業(yè)銀行股票收益率網(wǎng)絡(luò),考量貸款利率市場化前后商業(yè)銀行股票網(wǎng)絡(luò)的拓?fù)湫再|(zhì)變化。結(jié)果表明:貸款利率市場化前后,16家商業(yè)銀行股票收益率相關(guān)系數(shù)沒有發(fā)生顯著變化,網(wǎng)絡(luò)的平均路徑長度及聚集系數(shù)也未發(fā)生明顯變化,但貸款利率市場化后國有五大行股票收益距離更近,彼此相關(guān)性更強(qiáng),網(wǎng)絡(luò)中心節(jié)點(diǎn)變化較大。
[Abstract]:By using the complex network method, the paper constructs the stock yield network of commercial banks, and considers the change of the topological nature of the stock network of commercial banks before and after the marketization of loan interest rate. The results show that the correlation coefficient of stock yield of 16 commercial banks has not changed significantly before and after the marketization of loan interest rate, and the average path length and aggregation coefficient of the network have not changed significantly. However, after the marketization of loan interest rate, the stock returns of the five state-owned banks are closer, more closely related to each other, and the network center node changes greatly.
