Tax revenue data shows that the deepening of the construction of a unified national large market will be promoted by 2025.

The State Administration of Taxation uses big data on tax collection such as value-added tax invoices to conduct analysis on interprovincial trade and has found that the construction of the unified national market will be further promoted by 2025. Interprovincial trade is rapidly developing nationwide. In 2025, the sales volume of interprovincial trade in the country increased by 4.5% year-on-year, higher than the national sales revenue growth rate, accounting for 41% of the national sales volume, up 0.8 percentage points from the same period last year. Looking at the 31 provinces and regions nationwide, more than 80% of them have achieved positive growth in interprovincial sales volume.
