Abstract
This paper aims to explore urban geography with a new perspective. Endowed with the urban geography
connotations, an improved data field model is employed to integrate temporal dimension into spatial process of cities
in a typical region in this article. Taking the Beijing-Shanghai corridor including 18 cities as an example, the authors
chose the city centricity index (CCI) and the spatial data field model to analyze the evolution process and features of
sub-region and urban spatial interaction in this corridor based on the data of 1991, 1996 and 2002. Through the analysis,
we found that: 1) with the improvement of the urbanization level and the development of urban economy, the cities’
CCI grew, the urban spatial radiative potential enhanced and the radiative range expanded gradually, which reflects
the urban spatial interaction’s intensity has been increasing greatly; 2) although the spatial interaction intensity among
the cities and sub-regions in the Beijing-Shanghai corridor was growing constantly, the gap of the spatial interaction
strength among different cities and sub-regions was widening, and the spatial division between the developed areas and
the less developed areas were obvious; and 3) the intensity of the spatial interaction of Beijing, Shanghai and their
urban agglomerations was far greater than that in small cities of other parts of the corridor, and it may have a strong
drive force on the choice of spatial location of the economic activities.
