Common prosperity is a key feature and content of the Chinese modernization. It is also an important criterion for measuring whether the Chinese modernization succeeds or not. In the context of the continuous deepening of global technological revolution and industrial transformation, new quality productive forces have become an internal requirement and important focus of the construction of Chinese modernization. Hence, how to grasp the historical opportunity brought by this "production revolution" and promote common prosperity in a solid way is a major issue in the process of Chinese modernization. In response to this question of the times, this study, taking an approach that combines theoretical analysis with practical development, makes an in-depth analysis on the mechanism of new quality productive forces promoting common prosperity, and proposes specific practical suggestions from five aspects: accelerating the construction of inclusive and shareable information infrastructure; empowering the development of the real economy with new quality productive forces; vigorously developing the platform economy; innovating and developing the digital cultural industry, and constructing new production relations through deepening reforms.
