银行竞争、影子银行业务与银行个体风险

Bank Competition,Shadow Banking and Bank Idiosyncratic Risk

激烈的银行竞争对银行个体风险具有重要影响,而防范金融风险对维护金融稳定有着深远的意义.文章采用16家上市银行从2009年至2017年的季度数据,运用可行的广义最小二乘法实证分析了银行竞争对影子银行规模的影响,以及在影子银行业务的作用下银行竞争对银行个体风险的影响.实证结果表明:银行竞争会显著提高中国影子银行规模;在不考虑影子银行业务时,激烈的银行竞争能够降低其个体风险,具有风险分散效应;但如果将影子银行业务纳入考虑范畴,银行竞争则会通过该渠道放大银行个体风险.

The fierce bank competition has a vital impact on bank idiosyncratic risk.At the same time,how to prevent financial risks is important for maintaining financial stability.This paper empirically examines the impact of bank competition on shadow banking by feasible generalized least squares,employing the quarterly data of 16 listed banks from 2009 to 2017.And we also explore the impact of bank competition on individual bank risks under the influence of shadow banking.The results show that bank competition is the significant reason of rapid development of shadow banking.Moreover,without taking shadow banking into consideration,the fierce bank competition can reduce its individual risk and have a risk diversification effect.But if shadow banking is involved,bank competition amplifies the bank idiosyncratic risk through shadow banking.
