First of all, be serious. There is something wrong with this question: the criterion of urban planning theory should not be advanced or not. How the emergence of a theory is closely related to the social, economic, political and other backgrounds of its time. For specific problems, the methods and opinions put forward by people (not necessarily planners) to pay attention to and solve these Wiesenthal problems have been absorbed by urban planners, and learning has become today's planning theory. However, although the planning theory is not advanced, it will be outdated. There are two reasons: First, there will always be such and such problems in the development of cities, and a theory cannot cope with them. Just like the sinicization of Marxism, every leader will always deepen it according to the specific background of the times. Secondly, the urban planning theory itself sometimes brings some unexpected problems. These two points lead to the theory not adapting to the development of urban construction, resulting in the emergence of new theories.

Therefore, it is meaningless to simply discuss whether urban planning is advanced or not. Instead, a theory should be comprehensively evaluated according to the problems it aims at and its effect on solving problems.

Secondly, guess the meaning of the subject. The subject probably wants to find some fashionable or dominant urban planning theories, and try to sort them out. The knowledge is limited, but this one is too complicated. Please ask other experts to sort it out systematically. I can only mention it a little, but it is not systematic. Please correct me if there are any mistakes.

Nowadays, the development of urban planning theory mainly deals with the changes from three aspects: globalization, environmental problems and the worsening of social problems. To deal with these challenges, there are mainly related theories such as urban agglomeration, metropolitan area, metropolitan continuous belt, sustainable development theory, world urban system and so on at the regional level ... Urban level mainly includes new urbanism (although it was put forward in 1990s, it is now the mainstream), communication planning theory ... In terms of planning ideas, there are postmodernism, neo-Marxism and so on.
