This paper analyzes the impact of digital financial usage on household consumption upgrading using data from the China Household Finance Survey (CHFS) 2015–2019. Overall, using digital financial services stimulates household consumption and enhances consumption patterns. Mechanistic analysis indicates that digital financial usage positively influences consumption upgrading by optimizing household financial asset allocation. This is evidenced across four dimensions: participation in risky financial markets, augmentation of risky asset allocation, and enhancement of financial investment portfolio diversity and efficacy. Furthermore, the influence of digital financial usage on consumption upgrading varies according to age, wealth, and region differences.
