摘　　要：银行业市场结构与效率的关系比其他行业更为复杂,文章使用63家银行的非平衡面板数据,深入探讨了考虑信用风险情形下,我国银行业竞争对效率的影响。结果发现,由于信息不对称,竞争加剧会降低银行业的效率水平,支持"银行特质假说";资产规模和核心资本率与银行效率显著正相关,而重大事件中的引入境外战略投资者、银行跨区经营会降低银行的效率水平,并且经济增速较快时银行效率水平更低;国有行市场垄断力对效率的正向效应最强,其次是区域性银行和股份行。因此,当前我国健全完善金融市场体系,提升银行业效率,必须加快加强信用体系建设以缓解信息不对称;银行自身要提升风控水平,同时谨慎引入战略投资者和跨区新设机构;而股份行应是市场化改革的先行先试者。The relationship between market structure and efficiency is more complicated in bank industry than that in other in.dustries,this paper,based on the unbalanced panel data of 63 banks,makes an in-depth study on the effect of banking compe.tition on efficiency in China by taking the credit risk into account.The results shows that intensifying competition declines the efficiency of banking industry because of informationasymmetry,which“supports banking specificities hypothesis”;The scale of assets and the core capital ratio are significantly positively correlated with banking efficiency,whereas the introduction of foreign strategic investors and the cross-regional operation of banks in big events decrease banking efficiency,and the banking efficiency is lower when the economic growth is faster;The market monopoly power of state-owned banks has the strongest pos.itive effect on efficiency,followed by regional banks and joint-stock banks.Therefore,at present,in order to improve the finan.cial market system and enhance the efficiency of banking industry,China must accelerate the construction of credit system to alleviate information asymmetry;Banks should improve the level of risk management and consider seriously about new strate.gic investors and cross-regional institutions;Market-oriented reform should be promoted in joint-stock banks firstly.
