| 摘 要： | 以上市公司的长期银行借款为基本关系,构建银行共同贷款网络,运用复杂网络理论,对比研究了2000年和2009年的网络特征,发现:①非国有大型商业银行首先是争夺国有大型商业银行的市场,而不是自身的相互争夺;②全国股份制商业银行,虽然在上世纪90年代已相继成立,但业务开展并不好,但在样本期间,业务发展相当迅速,形成仅次于国有大型商业银行的中心节点,与国有大型银行共同形成银行系统的核心集团;③虽然国有大型商业银行仍是整个银行系统的中心,但中心地位已有所下降,对整个银行系统的影响力也显著下降,且各国有大型商业银行的影响力已趋于一致,专业性界限已非常模糊;④银行间,特别是居于核心集团的银行之间的共同客户越来越多,银行间接触更加频繁,这不仅是银行间竞争的加剧,同时银行间信息的分享和风险的分担都加强了。

| Abstract: | Taking the long-term bank loans of China’s listed companies as the basic relationship to build the co-financing bank network,network characteristics are comparative studied in 2000 and 2009 based on complex network theory.It is found that:(1) large non-state-owned commercial banks compete for large state-owned commercial banks in the market,rather than compete with their own;(2) the national shareholding commercial banks have been established in the 1990s,but the development of their business is not pretty good;however,during the sample period,the business developed rapidly and have been the central nodes after large state-owned commercial banks,all of which form the core of the banking system;(3) although the large state-owned commercial banks are still the center of the entire banking system,their center position has declined,and their influence on the entire banking system is also significantly decreased;moreover,the influence of large state-owned commercial banks have been consistent,and the professional boundaries are very blurred;(4) more common clients of the inter-bank,especially the banks in the core group,have more attachments,which intensifies the competition between banks while the information sharing and risk-sharing are enhanced. |
