附属村镇银行“代理扩张”与地方性商业银行风险承担--基于银行微观数据的实证研究

“Agency Expansion”of Affiliated Rural Banks and the Risk Bearing of Local Commercial Banks--An Empirical Research Based on Micro Data of Banks

本文基于2007-2021年210家地方性商业银行数据,运用固定效应模型和多期双重差分法评估附属村镇银行“代理扩张”对地方性商业银行风险承担的影响。研究发现,附属村镇银行“代理扩张”显著加剧了地方性商业银行风险承担。通过对比分析发现,其直接传递方式为合并报表,稳健性检验证实了结论的可信度。机制方面,该效应既通过改变资产配置,也通过激化行业竞争实现。异质性方面,农商银行和中部地区银行风险承担的效应更强。

Based on the data of 210 local commercial banks during 2007-2021,this paper uses fixed effects model and multi period Differences-in-Differences method to evaluate the impact of“agent expansion”of affiliated rural banks on the risk-taking of local commercial banks.It is found that the“agency expansion”of affliated rural banks significantly increas-es the risk-taking of local commercial banks.Through comparative analysis,it is found that the direct transmission method was through consolidated reports,and the robustness test confirmed the credibility of the conclusion.In terms of mecha-nism,this effect is achieved through both changing asset allocation and intensifying industry competition.In terms of het-erogeneity,the risk-taking effect is more significant in rural commercial banks and banks in Central China.
