The situation in urban studies has developed into a new phase. It is now at the height of a remarkable ferment. Ten years ago, for example, it was only a striking phenomenon in the field of urban studies that urban geographers had produced leading efforts on urban demography and regional planning. But, nowadays, substantial researches on Soviet urban problems are executed and accumulated in many disciplines, particularly political science, sociology, city planning, economics, urban engineering. This trend illustrates advances in the last decade in quantity and quality of urban studies. In this note, first, we examine external circumstances which caused and stimulated foregoing tendencies in the field of urban studies, and second, we adjust the content of various controversies spouting after deep consideration of described social bases and catch it in three point at issue : [ 1 ] Is there a cross-cultural urbanism? [ 2 ] Can urban community be preserved? [ 3 ] Should the size of the city be limited? Finally, we are concentrating on the critical comment on such controversies accompanied with methodological problems. The purpose of this note is not to question directly a contradiction between " socialist" policies and the realities of urbanized society. But, we'll have to challenge this theme some day.
