摘 要:

利用我国商业银行的样本,发现传统银行涉及的影子银行业务增加了银行风险并且降低了银行效率。效率的下降与中国影子银行业务的整体增长以及银行的规模、所在地和所有制结构显著相关。风险较高的银行往往会通过“转移效应”降低效率。笔者还发现,实证结果对效率的估计,特别是对于银行生产函数中投入和产出变量的选择是敏感的。忽视资产负债表外风险会导致总体风险的低估和银行效率的高估。

Abstract:Using a large sample of Chinese commercial banks, we find that shadow banking activities involved by the traditional banks increase bank risk and reduce bank efficiency. The reduction in efficiency is significantly related to the overall growth of shadow banking activities in China, and the size, the location, the ownership structure of the banks. The higher risk-taking banks tend to decrease in efficiency more through “diverting effect”. We also find that the results are sensitive to the estimation of the efficiency, particularly, to the choice of input and output variables as in the bank production functions. Ignoring the off-balance-sheet lending leads to underestimate the overall risk and overestimate the efficiency of the banks. 
 

Key words:shadow banking activities; banks’ risk and efficiency; measure of efficiency
