Information technology impacts on urban spatial structure in the Chicago region

This paper examines the impact of information technology on urban spatial structure in the Chicago region. Urban scientists are challenged to understand in what ways information technology has influenced the distribution of urban economic activities: concentration or dispersion. Using data collected in the Chicago region, orientation Of establishments toward the center is tested to separate the impact of locational features Of centers from the impact of information technology. The result reveals that information technology has attraction as well as spillover effect on urban spatial structure and thus concentration rather than dispersion is dominant at a local scale in the Chicago region. It was found, however that center-orientedness varies depending on the sector.
