Shared prosperity is an essential feature of socialism and also an important feature of the Chinese-style moderniza-tion,which reflects the pursuit of fairness and justice in the new era."Deservedness"is a traditional philosophical idea that has existed since ancient times,reflecting the concept and principle of social justice,and showcasing the values and ideals of hu-manity."Deservedness"and"justice"belong to the same sequence of categories,and people always use"deservedness"or not to determine whether social distribution is justified.The decades-long development of the People's Republic of China has laid a solid material foundation for achieving shared prosperity,but currently we still face the problems of fairness and justice such as imbalanced regional development and excessive income inequality.Promoting the process of shared prosperity is a must to solve the major social contradictions and realize the Chinese-style modernization,and also reflects the value orientation of deserved justice in Marxist theory.Deserved justice is consistent with shared prosperity in terms of premise,stance and value orientation.The application of Marx's theory of deserved justice to constructing a discourse system of justice in the new era of China is an ef-fective way to achieve shared prosperity and has great contemporary significance.Thus,the orderly development of human socie-ty requires the theoretical support of"deservedness".
