摘　　要：商业银行的信贷应该集中管理还是分散投放是一个需要回答的战略问题。笔者基于2007—2011年中国16个上市商业银行的信贷投放的数据,通过建立面板模型从风险和收益两个角度研究商业银行信贷投放的行业分散程度对银行的影响。研究发现,在当前我国商业银行信贷分散的情形下,随着集中度增加银行的信贷资产风险将加大,同时银行的收益也会增加,即如果银行选择更高收益的策略就意味着要承担更高的风险,这与高风险高收益的认识相一致。信贷资产的不同风险状况跟信贷风险的边际收益贡献没有明显的关系,这与国外实证结论不一致,但是银行的经营能力决定了银行应该选择的分散程度,更强经营管理效率的银行可以选择更加分散的信贷投放。笔者建议我国商业银行可以在控制风险的情形下适度增加集中度。Should banks be focused or diversified？ This is a strategy question for Chinese banks to answer. Based on the panel data from 2007 to 2011 of China＇s 16 listed commercial bank, we build model to analyze how industrial diversification impact the banks＇ risk and performance. We found those banks＇ credit risk increases with the increase of industry concentration and return is also increasing, i.e. if the banks select higher return strategy, they need to take on more risk, which is consistent to common sense. We found little evidence of lager risk adjusted performance benefits associated with diversification. However, we found evidence that operation ability is a quite important factor of diversified decision using the recent 3 years data. The banks with higher operation ability could be more diversified.
