Abstract: The development of portcity has been paid much attention to in China since 1978,but most of the researchers studied ports and portcities separately.However,this paper tries to link them together,studying the economic development of portcity on the basis of portcity interaction theory,The author believes that the three driving forces which play an important role in the urban development are.portcity direct linkage,portcity indirect linkage and the self-growing process of portcity.The analysis of the characteristics of driving forces indicates that there are distinctly different periods in the movements of driving forces combination.Because of the evolution of driving forces combination,the developing process of portcity appears to be composed of three stages,the stage of primary commercial economy,the stage of port-industrial economy and the stage of multiple economy.Having studied the history of seaports and portcities in North China,the paper discusses factors affecting the direction and the speed of the development of portcities,The universality and applicability of portcity development model are also discussed in the article.
