During the epidemic, the fan economy helped many industries get out of the trough and achieve re‐profitability. At the same time, star idols use their own advantages to guide the public to participate in public welfare activities, which greatly promotes the development of public welfare undertakings. However, the blind follow of fans and the social influence of inferior artists have also restricted the long‐term development of the fan economy. Promoting the effective integration and development of fan economy and social welfare, realizing the dual value of economic development and social progress are the core competitiveness of the long‐term development of fan economy.
