This paper uses the methods of System Generalized method of moments (SYS-GMM), mediation effect and linkage effect to investigate the relationship among social organization participation, government governance and the equalization of basic public services from 2007 to 2017 in China. The empirical results show that the participation of social organizations and improvement in the government governance can promote the equalization of basic public services. The government has a greater capacity to drive the equalization of basic public services, but the density of social organizations can serve as a mediator in the equalization of basic public services. The government governance and social organization density have a strong linkage effect, but the link with social organization quality is weak. Furthermore, a linkage effect is evident in medical and health care, public education, environmental protection, and public culture but not in public science and social welfare.
Keywords: equalization of basic public services; government governance; social organization.
