摘　　要：经济增长和收入分配改善是共同富裕的应有之义,也是实现共同富裕的重要途径。商业银行普惠金融以中小微企业和农民等弱势群体为主要服务对象,是推进共同富裕的重要力量。本文在包含BGG金融加速器的DSGE模型中引入异质性企业和异质性家庭,从经济增长和收入分配角度分析商业银行普惠金融政策对共同富裕的动态一般均衡影响。校准参数后模拟发现,商业银行普惠金融政策会促进共同富裕。对比分析发现,宽松货币政策虽然会增加总产出,但会加剧收入不平等;同时,商业银行普惠金融政策和小企业技术进步的组合冲击更有利于实现共同富裕。Economic growth and improved income distribution are intrinsic to common prosperity and essential pathways to achieving it.Inclusive finance provided by commercial banks,targeting vulnerable groups such as small and micro-enterprises and farmers,plays a crucial role in advancing common prosperity.This paper introduces heterogeneous firms and households into a DSGE model incorporating the BGG financial accelerator to analyze the dynamic general equilibrium effects of commercial banks'inclusive finance policies on common prosperity from the perspectives of economic growth and income distribution.After calibrating the parameters,simulations reveal that inclusive finance policies of commercial banks promote common prosperity.Comparative analysis indicates that while expansionary monetary policy increases total output,it exacerbates income inequality.Moreover,a combination of inclusive finance policies by commercial banks and technological progress in small enterprises is more conducive to achieving common prosperity.
