Abstract：The structure of current grassroots governance has some autonomy space， but no autonomy right，which is a singlecenter (centralized) authoritative order，not a polycentric (decentralized) one. The construction of local social autonomy lies in the following three aspects. Firstly，we need to guarantee the autonomous right by law，which includes defining social autonomy right and clearing the meanings and boundaries between citizens and the state，as well as the autonomous agents from different levels. Secondly，we should constitute a multicenter governing subject，which contains the people from the government，the society and the market. Thirdly，it’s wise to reconstruct the society，and only getting rid of the attachment to the state can the principle of social autonomy be built up. From the perspective of overall grassroots governance，the construction of a power structure system of local social governance has a significance of institutional innovation， which can organize the social interests and maintain the social orders.
