Wu Jingchao put forward the theory of "developing cities to relieve rural areas" in his masterpiece "The Way Out of the Fourth Country". According to the two standards of population density and occupation, he divided the countries in the world into four types, and believed that China belonged to the fourth type of country, and the way out lies in: making full use of domestic resources; Improving production technology; Implement fair distribution; Control the population and advocate "using mechanical production methods to replace muscle production methods". He is one of the earliest representative figures in Chinese sociology to study urban sociology, focusing on the study of society, especially urban society, from the economic point of view, and also discussing the ideal city and other issues.

Wu Xiaobo was one of the first representatives of the Chinese sociological community to study urban sociology. He focused on studying society, especially urban society, from an economic perspective. In his book Urban Sociology, he explained the scope of research in urban sociology, introduced the method of research in Western urban sociology, and clearly defined the differences between the two concepts of "urban area" and "urban area", believing that urban areas not only include the city itself but also the subordinates outside the city, while urban areas mainly refer to the situation of the city itself.
