This report combs the business model，main characteristics and existing problems of online education platforms，analyzes the impact of “double reduction” on online education platforms in combination with the content of the “double reduction” policy，and focuses on the transformation strategy of Beijing online education platform represented by New Oriental under the impact of the “double reduction” policy. Online education platforms have both platform advantages and educational functions，and have played a great role in replacing the traditional education model during the COVID-19. However，the disorderly expansion of various platforms has worsened the learning and education environment and overburdened students and parents. In this context，the “double reduction” policy not only strictly governs the problems of online education platforms，but also guides the education industry to return to rationality. For example，New Oriental explores the transformation from quality education，adult education，online live broadcasting and other business directions，and announces the success of the transformation through bilingual live broadcasting. In the future，in the process of establishing a national public online education service system，online education platforms will have great prospects.
