The realization of urban modernization requires not only specialized and technical means，but also a comprehensive and fundamental management approach. Modernization of government governance mainly involves two aspects：first，the modernization of government functions；second，the modernization of the government governance system. The modernization of cities cannot be separated from the modernization of government governance. In pushing forward the process of urban modernization，we should pay attention to the application of modern professional and technical means，but also to the construction of modern governance system and urban modernization led by modernizing government governance.
