Research on Interaction among Cities in Urban Agglomeration

Aiming at the interaction intensity problem of cities in urban agglomeration, the gravity model of interaction among cities in urban agglomeration is set up to find the influence factors of the interaction and put forward the efficient method to promoting the interaction among cities in urban agglomeration. Firstly, analyzing the manifestation of the interaction and introducing traditional gravity model. Then, improving the city quality and distance measurement method and determine model. In the end, the interaction among cities in HuBaoOr urban agglomeration is obtained based on related data. The result indicated that with the repaid development of society, economic, transportation and communication, the contact of cities has been strengthened and the space interaction also increasing. The interaction is the requirement of cities' normal operation and it also is the foundation of cities to achieve mutual benefit and seek further professional development. In this way, the researches on interaction among cities in urban agglomeration is very meaningful.
