The research on the economic interaction among cities is beneficial to understand the spatial organization of regions and urban economy, to clarify the space developing orientation of regions and city entities, and to organize transportation reasonably. It provides references for the guiding and strengthening of regional and urban spatial interactions, and the optimization of spatial structure of urban system. Based on the methods of Gravity Model, Potential Model and Subjection Model which are interacted in space, this research quantitatively analyzes the spatial pattern and evolution of the urban economic links in the northeast region from 1992 to 2012, taking 41 cities in the northeastern China as study objects. It provides references for strengthening the spatial interaction among cities in the northeast region and promoting the economic sustainable development in the cities of the northeast region. The result of the study shows that there is close relationship between the economic relation intensity and regional spatial structure, the more intense the economic relation is, the more complicated the regional spatial structure will be. In the northeastern China, the time-space differences are significant that the economic relation intensity in the south is higher than in the north and it is higher in the middle part than on the two sides. In the recent 20 years, the regional economic development pattern represented by Shenyang, Changchun and Harbin has been formed. There is no change in the cities in the center of the region but the closest linkage among cities changed distinctively. The economic development in the northeastern China presents feature from south to north and from middle to sides. Finally, this article puts forward the concept of River Basin City and its pattern, and makes a concrete analysis.

Key words: spatial economic links, river basin city, gravity model, the northeastern China
