Digital financial inclusion provides financial services through digital platforms, aiming to improve the ability of MSMEs and low-income groups to access financial resources, thereby easing their financing constraints and promoting economic growth and inclusive development. As an innovative financial model, digital financial inclusion utilizes modern technological means to significantly improve the accessibility and convenience of financial services, especially in areas where traditional banking services are under-covered. Digital finance has promoted the popularization of financial services such as micro-credit, micro-savings, and micro-insurance, and helped improve the financing environment of low-income groups and small and micro enterprises. At the same time, digital financial inclusion promotes financial literacy education and digital inclusion construction, and enhances the acceptance and use of digital financial instruments by the general public, which is the key to achieving sustainable development of digital financial inclusion. Therefore, digital financial inclusion can better ease the financing constraints of small and medium-sized enterprises and promote economic development.
