Grassroots governance is an important part of national governance，and the realization of grassroots governance modernization is an important way to promote the modernization of national governance system and governance capacity. At present，jiangsu cities are actively carrying out the practice and exploration of grassroots governance modernization，and the typical experience of Changzhou，Nanjing，Yancheng and other cities with their own characteristics is pouring out. The typical experience of these cities in the process of promoting the modernization of grassroots governance is summarized in order to provide experience for the modernization of provincial and even national governance. However，jiangsu cities also encounter some problems in the practice of grassroots governance modernization：the governance concept is not advanced enough，the system and mechanism are not scientific enough and the supply of resources is insufficient. To solve these problems，efforts should be made to change the governance concept，optimize the system and mechanism，and ensure sufficient supply of resource factors.
