我国正在推进利率市场化改革,需要对于商业银行股权多元化和发行上市的成效进行总结。本文采用主成分分析法构建了我国上市银行的综合绩效指标体系,然后实证分析了股权结构对于银行综合绩效等指标的影响。在面板数据分析中,我们发现我国上市银行的综合绩效不断提高,坏账比例逐年下降,净资产收益率有所提高。同时,我们进而发现,股权集中度与我国上市银行综合绩效呈倒U型曲线关系;我国上市银行中,传统国有银行比股份制银行绩效要差;海外上市对我国银行绩效有推动提升作用。我们认为,我国金融改革需要进一步优化我国商业银行的股权结构。
Given the recent progress of the interest marketization in China, it is inneed toexamine whether and how ownership diversification of banks work in China. We constructthe comprehensive indicator of performance with the principal component approach and thenexamine the panel data of all the banks publicly listed in the Chinese stock market. We findthat the bank performances keep increasing and the bad loan ratios keep decreasing afterownership diversification and public listing. We further find that there are an inverted U-shaped relationship between ownership concentration and the bank performance, that thebanks with the state as the controlling shareholder perform worse and that the oversea publiclisting improves bank performance. It needs to deepen its financial reform with optimizingthe shareholding structures of the Chinese banks.
