扩大内需是构建新发展格局的战略基点，税收政策对居民消费能力的影响甚深。文章基于2011—2020年省级面板数据，检验自2008年全球金融危机后我国以减税和税制结构调整为主要方向的税收政策对居民消费的影响效应。结果表明：随着我国减税力度的不断加大和减税政策的逐步实施，各地人均税收增幅不断放缓，居民消费率得到有效提高；减税政策实施过程中伴随着的整体税制结构优化，能通过改善群体间的收入分配提高居民消费率。今后应继续有针对性地推行减税政策，进一步优化税制结构，加大对群体间收入分配的调节力度，提振居民消费信心，释放居民消费潜力。

Expanding domestic demand is the strategic basis of building the new development paradigm, while the tax policy has a deep impact on residents' consumption ability. Based on the province-level panel data from the 2011 to 2020, this paper examines the effects of China's tax policies, which mainly focus on tax reduction and tax structure adjustment, on household consumption since the financial crisis. The results show that with the increase of tax reduction and the implementation of local governments, the growth rate of per capita tax has been slowed down and the consumption rate of local residents has been effectively increased. The optimization of the overall tax structure accompanied by the implementation of the tax reduction policy can play a positive role in the consumption rate of residents by improving the income distribution among groups. In future, we should continue to implement targeted tax reduction policies, further optimize the structure of the tax system, increase the adjustment of intergroup income, boost residents' consumption confidence, and truly release the consumption potential of residents.
