摘　　要：加快构建新发展格局需要“增强消费对经济发展的基础性作用”并“稳步提高居民消费水平”,面对这一重大现实经济问题,深入思考“推进共同富裕”与“构建新发展格局”之间的关系。本文利用中国家庭金融调查数据,聚焦于财富不平等对中国居民消费的影响及其相关机制。基于中观层面加总数据的实证分析表明,财富差距显著抑制居民消费支出,财富差距对居民消费的抑制效应高于收入差距。通过分析近20年来财富差距和平均消费倾向的变动趋势,财富差距能够解释中国居民平均消费倾向下降的58.6%。微观层面的机制研究表明,财富差距通过消费收入敏感性、流动性约束、财富-地位寻求动机以及社会资本四个渠道抑制居民消费。本文的研究结论表明实现共同富裕是构建“双循环”发展格局和实现高质量发展的根本途径。The problem of income inequality between the rich and poor in China is still prominent.From the perspective of income disparity,the Gini coefficient of Chinese residents income has risen from 0.34 in 1995 to a-round 0.64 in 2016,which is higher than the international warning line of 0.4.The wealth gap is even more signifi-cant,with the Gini coefficient of wealth distribution among residents approaching 0.8 by 2016.The expansion of the rich-poor gap may be one of the important driving factors that suppress total demand,but most research attempts to explain the fact that Chinese residents have"low consumption and high savings"from the perspective of income inequality,and there are few studies on the consumption suppression effect of wealth distribution.Based on the comprehensive consideration of income distribution,this article focuses on the problem of insufficient consumption of residents from the perspective of wealth disparity,and the main conclusions are as follows.First,the expansion of wealth inequality significantly reduces residents'consumption expenditure.For every 0.1 increase in the Gini coefficient of wealth,residents'consumption expenditure decreases by 2.44%,and the negative effect of wealth disparity on residents'consumption is higher than that of income disparity.Starting from the social organization behavior and cultural perspective derived from the production mode,this article takes the suitability of wheat and rice as an instrumental variable,and after overcoming endogeneity,we find that the negative impact of wealth disparity on residents'consumption is still robust.Second,the mechanism analysis reveals that as the wealth class rises,the consumption income elasticity of the affluent class decreases.Although the large middle-and low-class groups have a higher consumption tendency,they face tighter financial constraints,and the higher liquidity constraint level makes it difficult for consumption to increase.Accumulating wealth can also lead to gaining psychological satisfaction,and the expansion
