摘要

This study aims to analyze and explain, from a locational perspective, differences in the performance of Wal-Mart and Kmart stores in the Greater Cincinnati Area. A modified Huff model, taking competition and agglomeration into consideration, is developed to estimate the potential sales of individual Kmart and Wal-Mart stores. Results show that the modified Huff model is capable of more accurately estimating individual store sales than traditional interaction models. This study also suggests that the selection of store locations partially explains the difference in performance between Kmart and Wal-Mart stores. The model is calibrated using data collected in 2003, and the validity of the model is supported by the latest development of the stores in Greater Cincinnati Area since 2003.
