China is a country with a long history of agricultural development, the tradition of bureaucratic administration and economic management systems for the social development. In its transition from traditional society to modern society during the past 50 years, the relations between rural areas and urban areas have been kept abnormal if considered from the point of view of the modernized countries. Today, China still has its more than 70 percent of population, but limited capital, lower technology and underdeveloped culture, in the rural areas. This unbalance forms not only the obstacles to opment. This paper focuses on the discussion about the coordinate development of the relations between rural and urban in the past 50 years, and the authors hold that only has the abnormal relation between the two areas been corrected, could Chinas future development of national economy be successful.
