摘　　要：与工商企业相比,银行业的杠杆比例明显偏高。这种普遍存在的鲜明对比与经典的公司财务理论是矛盾的。本文从银行的本质特征分析银行资本结构的特殊性,考察商业银行市场均衡资本的形成、银行安全网、资本监管对银行资本结构的影响,并从经济资本、监管资本、会计资本的角度研究银行资本数量的确定。本文认为商业银行最优资本结构难以确定为具体的比例,可以大致地定义在一个合理区间里。Banking sector has higher leverage ratio than other industries. This striking comparison is contradictory to classic theory of corporate finance. This paper analyzes characteristic of banks＇ capital structure based on uniqueness of commercial banks and studies effect of safety net and capital regulation on banks＇ capital structure. We discuss the decision of capital from economic capital, regulatory capital and book capital respectively. This paper points out that it is very difficult to calculate a specific optimum capital ratio for a commercial bank, however we can define a reasonable range of bank capital ratio.
