Tax data indicates that the construction of China's national unified market advanced significantly in 2025. According to an announcement from the State Taxation Administration on March 2, analysis of inter-provincial trade using value-added tax invoice data and other big data resources showed deepened progress in building a unified national market.

Inter-provincial trade across the country expanded rapidly. In 2025, sales revenue from trade between provinces increased by 4.5% year-on-year, outpacing the overall national sales revenue growth rate. Inter-provincial trade accounted for 41% of total national sales, up 0.8 percentage points from the same period last year. Among China's 31 provincial-level regions, more than 80% (26 provinces) reported positive growth in inter-provincial sales.

Key economic regions demonstrated strong radiating and driving effects. In 2025, sales to regions outside their own areas by the Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl River Delta regions grew by 4%, 6.2%, and 4.6% year-on-year respectively. These figures exceeded the overall growth rates of these regions by 0.9, 3.1, and 1.7 percentage points respectively. Similarly, the Yangtze River Economic Belt and the Yellow River Basin saw their external sales increase by 5.8% and 4% year-on-year, surpassing their respective overall growth rates by 2.5 and 3.7 percentage points. Trade between major regions remained active, with sales from the Beijing-Tianjin-Hebei region to the Yangtze River Delta growing by 6.7% year-on-year, and sales from the Yellow River Basin to the Yangtze River Economic Belt rising by 5.2%. Sales from the Yangtze River Delta and Pearl River Delta to the Chengdu-Chongqing region increased by 5.7% and 7.8% year-on-year respectively.

An official from the relevant department of the State Taxation Administration stated that establishing an efficient, standardized, fair, competitive, and fully open national unified market is crucial for smoothing domestic circulation and laying the foundation for a new development pattern. It also represents an inherent requirement for promoting high-quality economic development. The tax authorities will continue to thoroughly implement the central government's fundamental requirements for advancing the national unified market, focusing on "five unifications and one opening." They will remain steadfast supporters and promoters of the unified market, continuously enhancing the convenience of tax and fee services, the precision of tax supervision, and the standardization of tax enforcement to better serve the market's development.
