摘要
文章采用Herfindahl指数衡量商业银行贷款投放的多元化程度,发现商业银行贷款的行业多元化和地区多元化程度近年来不断提高。在此基础上,通过建立回归模型考察了贷款多元化对商业银行风险和收益水平的影响。研究结果表明:行业多元化程度与商业银行的资产净利率相关,并且行业多元化在一定程度上有助于提高商业银行的盈利能力;而行业多元化与商业银行的经营风险之间没有显著性的相关关系。地区多元化程度与商业银行的资产净利率和不良贷款率相关,并且地区多元化会导致商业银行盈利能力的降低,但是却在一定程度上有助于降低商业银行的经营风险。
This paper adopts Herfindahl Index to measure the loan diversification of commercial banks, and finds that the degree of industry diversification and geographical diversification of commercial banks has been incessantly on the rise these years. On this basis, regression model has been made to examine the effect of loan diversification on the risk and return of commercial banks. The research results indicate that loan diversification correlates with the ratio of return on asset of commercial banks, and it contributes to the profitability of commercial banks to some extent. Industry diversification has no significant relationship with the operational risk of commercial banks. Geographical diversification correlates with the ratio of return on asset and the ratio of doubtful loan of commercial banks, and it leads to the decrease of profitability of commercial banks, but helps to decrease the operational risk of commercial banks to a certain degree.
