在高质量发展的背景下，研究数字普惠金融对县域经济高质量发展的空间溢出效应尤为重要。本文的研究结果表明，数字普惠金融能有效促进县域经济的高质量发展，且对临近县域存在正向的空间溢出效应。通过机制检验发现，数字普惠金融的发展可以通过提高农业技术水平的方式促进县域经济的高质量发展。

Under the background of high-quality development, it is of great significance to study the spatial spillover effects of digital financial inclusion on such development. The findings of this paper indicate that digital financial inclusion effectively promotes the high-quality development of county economies and exerts a positive spatial spillover effect on neighboring counties. Mechanism tests reveal that the development of digital financial inclusion fosters high-quality economic growth at the county level by enhancing the level of agricultural technology.
