The arrival of large data age has brought new opportunities and challenges to the innovation of China\'s social governance. In this context, the transformation of techniques and methods of community management is an important means to improve the efficiency of community management and the mode of community governance. Community grid management mode is a new type of community governance mode which is multi-participation, standardized and orderly, making the realization of dynamic and refined community management possible. This paper takes five typical grid management communities in Chengdu as an example to explore in depth the current situation of community grid management in the city. Furthermore, we try to find out the existing problems through questionnaire and interviews, and present some corresponding countermeasures to solve the problems, hoping to provide some new ideas for the innovation of community grid management in Chengdu, China.
