This study investigates how the expansion of mobile payment platforms can be leveraged to enhance inclusive financial access in rural China, thereby promoting equitable financial coverage across underserved regions. Drawing on multiple authoritative secondary data sources, the analysis ensures robustness and credibility of the empirical findings. The results indicate that mobile payment service providers have substantially expanded their network coverage in rural areas, leading to significant growth in both the transaction value and volume of mobile payments. This expansion is positively associated with inclusive economic outcomes, particularly increases in per capita income and per capita consumption expenditure in rural China. Empirical evidence from descriptive statistics, correlation analysis, and regression models consistently confirms a statistically significant positive relationship between mobile payment adoption and indicators of inclusive growth. National and rural-level descriptive analyses further reveal that urban mobile payment markets are approaching saturation. This in turn reflects a deceleration in growth rates in the urban areas and a continuous rapid expansion in the rural areas of the country. Notably, the total number of mobile payment transactions in rural China increased by approximately 33% in 2024, highlighting substantial untapped growth potential. Overall, the findings suggest that the continued expansion of mobile payment platforms plays a critical role in facilitating financial inclusion and supporting inclusive economic development in China’s rural regions.
