Abstract

Against the global development dilemmas of class solidification caused by capital concentration, the decoupling of economic growth from social well-being, and the binary opposition of traditional ideologies, this paper systematically elaborates and establishes Eudaimonic Distributism as a new social theory. Taking the median social happiness index as the core development goal, the theory is grounded in the prerequisite of "the sanctity and inviolability of personal property" while integrating the core socialist principle of "distribution of social resources according to contribution". It constructs a theoretical system with three pillars: diversified opportunities, dispersed capital ownership, and contribution-based return matching. The core logic of the theory is as follows: monopolistic capital concentration compresses individual autonomy, deprives development opportunities, and thus lowers the median social happiness; in contrast, widely dispersed capital ownership, an open and diversified opportunity infrastructure, and an incentive mechanism that aligns contribution with rewards can maximize individual subjective initiative and realize the continuous improvement of the overall well-being of society. This paper also sorts out the academic origin of the theory, clarifies its institutional design system, responds to core theoretical challenges, and plans a phased practical path, providing an alternative paradigm for contemporary social development that balances efficiency and equity, freedom and security, individual development and social prosperity.
