As the times demand, new quality productive forces have emerged, and educational informatization is in full swing. Smart education, which has emerged from the digital era, has become a new engine for the development of education in China. Optimizing the public service of smart education can not only comprehensively enhance the quality of education but also conform to the requirements of new quality productive forces and promote the virtuous cycle of the three elements: science and technology, education, and talents. Despite certain achievements, such services still face issues including homogenized supply, formalistic technology application, uneven resource allocation, and imperfect guarantee systems. Based on new-quality productive forces’ core connotation and requirements (high technology, high efficiency, high quality, inclusiveness), this paper uses literature research to sort out their current status and problems, and proposes targeted optimization paths from supply model, technology integration, resource allocation, and guarantee system, providing practical references for promoting high-quality development of smart education public services and adapting educational digitalization to new-quality productive forces.
