Abstract: Based on the theory of Relative Income Consumption, this article uses household micro data to empirically analyze the impact of consumer infrastructure on the same group effect of consumption among residents. The results indicate that firstly, the consumption concept of residents is influenced by living environment factors, and the improvement of consumption infrastructure can significantly enhance the influence of peer consumption on resident consumption. Secondly, the analysis of the mechanism of action reveals that the construction of consumer infrastructure can improve the same group effect of resident consumption by promoting the upgrading of resident consumption structure and enriching resident social networks. Thirdly, the impact of consumer infrastructure construction on the consumption of different types of households has significant heterogeneity, with urban and middle-income households being more affected by the same group effect. Therefore, it is recommended that the government improve the modern consumption infrastructure system, promote the upgrading of consumer infrastructure, and improve the incentive system for the construction of consumer infrastructure.

摘要： 本文基于相对收入消费理论,利用家庭微观数据,实证分析了居民消费基础设施对消费同群效应的影响。结果表明:第一,居民消费观念受生活环境因素影响,消费基础设施完善可显著提高居民消费的同群效应;第二,作用机制分析发现,消费基础设施建设可通过促进居民消费结构升级和丰富居民社会网络来提高居民消费的同群效应;第三,消费基础设施建设对不同类型家庭消费的影响具有显著异质性,城镇家庭、中等收入家庭消费的同群效应受影响更大。因此,建议完善现代化消费基础设施体系,促进消费基础设施升级,并健全消费基础设施建设激励制度。
