Abstract：
This paper modifies the conventional gravity model by introducing an industrial division of labor coefficient, tests its validity with real inter-city bus traffic data and then computes the economic linkages in 2008, 2010 and 2012 respectively. Results show that: Xi’an takes the dominant position, but has much weaker linkages with Shangluo and Tianshui as opposed to what it has with other cities; Baoji is posited as the sub-center city that is next only to Xi’an, but does not demonstrate commensurate linkage effect; The economic zone is imbalanced with Shangluo and Tianshui as periphery cities that have lowest linkages. The whole region is presently characterized with single-nuclei hierarchical structure around Xi’an and should be re-oriented in the future toward multiple-nuclei inter-city network through further industrial division of labor among cities other than Xi’an.
