中国居民收入结构变迁与分配公平(2005-2022年)OA

Achieving common prosperity for all the Chinese people is one of the five defining characteristics of Chinese modernization.Optimizing the income distribution structure and developing a large middle-income group are crucial means to achieve this goal.Utilizing data from the Chinese Social Survey(CSS)and applying the National Bureau of Statistics'standard for middle-income households,this study reveals through statistical analysis that between 2005 and 2022,the share of low-income residents in China decreased significantly from 91.50%to 35.94%,lifting approximately 690 million people out of low-income status.Concurrently,the proportion of the middle-income group surged from 1.08%to 25.51%,expanding its size from around 14 million to 400 million people.Over the nearly two decades,China's income distribution structure has undergone a fundamental transformation,evolving from an"inverted T-shape"to a"pyramid shape,"with the preliminary formation of an"olive-shaped"structure—commonly known as a diamond-shaped structure—becoming increasingly evident.In the next phase,optimizing the income distribution structure should further promote integrated urban-rural development and coordinated regional development.Targeted policy measures should be implemented to facilitate the large-scale entry of the lower-middle-income group into the middle-income bracket,steadily achieving the milestone goal of establishing the middle-income group as the largest segment nationwide.
