Does Digital Inclusive Finance Improve Air Quality? Empirical Evidence from 285 Cities in China

Liu Songtao, Luo Weilin

Abstract: Air quality concerns every household and is a reflection of high quality development. Promoting a green transformation in the way we develop is the fundamental strategy to take the initiative in air pollution prevention and control. This paper uses panel data from 285 cities in China from 2011 to 2021 and measures the level of digital inclusive finance development and air quality with the Peking University Digital Inclusive Finance Index and the average concentrations of PM2.5, PM10, and PM1, three different equivalent diameter air particles. It examines the effect and internal mechanism of digital inclusive finance on urban air quality. The study finds that digital inclusive finance significantly reduces the concentrations of PM2.5, PM10, and PM1 in cities, improves air quality, and the results remain robust after testing with instrumental variable estimation and lagging the independent variable by one period. Heterogeneity analysis indicates that the impact of digital inclusive finance on urban air quality varies based on geographical location, administrative level, and resource reserves. Mechanism analysis based on the green transformation of development shows that digital inclusive finance improves urban air quality by promoting industrial structure upgrading, enhancing innovation capability, and fostering digital innovation entrepreneurship. Threshold effect testing reveals that the influence of digital inclusive finance on urban air quality exhibits non-linear threshold characteristics. The research conclusion of the article provides reliable theoretical and empirical evidence for the practice of leveraging digital inclusive finance to empower green high-quality development and assist in air pollution prevention and control.
