摘 要：2008年金融危机以后，小微企业融资难的问题日益受到人们的关注，而商业银行的信贷投放资金是解决小微企业资金短缺的重要途径之一。在此背景之下，国家相继出台了较多扶持小微融资的政策，商业银行出于自身结构转型的需要也开始向小微企业信贷业务倾斜，但是小微企业的不良贷款率等风险问题却让商业银行望而生畏，而且商业银行传统的信贷模式也难以适应小微企业的融资需求，改变自身的业务流程以及人员配备等需要较大的成本以及时间，信息的不对称问题更加剧了商业银行的贷款风险。出于这些因素的考虑，商业银行对小微企业惜贷。

　　　如何解决小微企业的融资问题同时促进商业银行的协调发展已经成为一项重要的课题，而如何缓解银企之间信息不对称的问题，是降低商业银行信贷成本以及贷款风险的主要问题，也是解决商业银行对小微企业惜贷的一个有效途径。本文从信息不对称的视角下，将理论与实践相结合，研究商业银行对小微企业贷款的主要风险，并且从商业银行和小微企业两个角度分析了贷款风险存在的原因，为我国商业银行控制小微企业提供新思维新方法，同时也有助于缓解小微企业融资难的问题。
