According to the current context of China’s new urbanization and urban and rural transformation,this paper defines incremental planning,stock-based planning,and reduction planning.It further discusses the socio-economic foundation of incremental planning,the transformation of incremental planning to stock-based planning,and the emergence of reduction planning,as well as the characteristics of these three types of urban planning.Based on that,it finds that incremental planning is determined by China’s unique urban growth pattern,and that the change of the urban growth mode leads to a transformation of urban planning.In addition,reduction planning can effectively cope with urban decline.After over 30 years of rapid economic development,more and more cities in China are approaching the bottleneck of growth.Therefore,the transformation of urban planning is unavoidable and will definitely become an important topic in planning circles.
