简介:经济增加值(EVA)作为一种价值管理的工具,是衡量银行创值能力的新方法。通过对42家城市商业银行2009年-2011牟的创值能力分析,从EVA的计算结果来看,大部分城商行都在创造价值,且创值能力不断提升。与国内大型商业银行相比,城市商业银行有其自身的特点,如决策权相对集中和市场占有份额较低等,因此,本文选取42家城市商业银行2009-2011年间前五家股东持股比例、高管平均年薪、董事会人数和主营业务收入这四个指标作为EVA的驱动因素进行分析。回归结果显示:主营业务收入和前五大股东持股比例对创值能力的影响显著,其中主营业务收入有正向影响,前五大股东持股比例则呈现负向影响;而高管薪酬和董事会人数的影响不显著。
