Abstract: With the transformation of China from traditional agricultural society to modern industrial society, the fragmentation, hollowing out, anomie and strangeness of rural are becoming increasingly prominent, and it is particularly urgent to standardize and promote the development of grass-roots society with a scientific governance system. The grass-roots governance system of “combination of three governance” takes the subject consciousness of the grass-roots people as the core and the leadership of the party organization as the core. It not only respects the production and life style of the grass-roots people, but also supports the grass-roots society with the historically developing law and morality. At the same time, the governance efficiency of the “combination of three governance” grass-roots governance system is characterized by improving the subject consciousness of grass-roots people and promoting their all-round development.
