摘　　要：现有文献认为与非国有商业银行相比，国有商业银行的效率较低，据此证明银行股份制改革的必然性。本文结合非意愿产出、四阶段DEA模型和Bootstrap法估算了1996-2006年中国商业银行X效率，发现国有商业银行X效率处于中下水平，其根源在于所有权以外的异质外部环境；非国有银行则出现两极分化，其主要由各自管理水平决定，受外部环境影响相对小。X效率高低和银行所有权形式并无明显的联系；纯技术效率对X效率影响较大，配置效率和上市对其影响较小。总体而言，银行X效率都在稳步提高，并具有较强的收敛趋势。Existing literatures show that the non-state-owned commercial banks arc more efficient than state-owned commercial banks, which proves the necessity of Joint-Stock reform. Employing four-stage model of DEA and bootstrap method, this paper investigates the X-efficiency of commercial banks in China from 1996 to 2006. State-owned banks have a lower level of X-efficiency due to the heterogeneity of the external environment, while there is a bipolar division in non-state- owned banks as a result of their management levels. The relation between X-efficiency and the form of ownership is not significant. The major factor impacting the X-efficiency of commercial banks is pure technical efficiency instead of allocative efficiency and public offering. Commercial banks have a steady increase overtime in X-efficiency, at the same time the overall X-efficiency shows a strong convergence trend.
