THE THEORY OF URBAN FUNCTION AND THE KERNEL POWER OF URBAN COMPETITION
Urban function theory is based on the assumption that the external environment is constantly unchangeable and the government is capable of doing anything. Obviously this should be amended according to the actual situation in practice. From this point of view, this paper points out three major defects of this theory and introduces the basic concept of urban competitiveness, especially by comparing the kernel power of urban competition and the urban function theory results in that these two theories should be integrated. The author believes that to the medium-sized and small cities the kernel power concept is more relevant than that of comprehensive competition.
