ABSTRACT

Excess commuting has been extensively examined over the past two and a half decades, but it has been argued in the previous research that the inconsistencies of spatial analysis zones could cause the variance in excess commuting estimates. This is related to the Modifiable Areal Unit Problem(MAUP) that addresses three main effects: (1) scale effect; (2) zoning effect; and (3) boundary effect. Among them, the first two effects have been investigated in the previous studies but the impact of the boundary on the results of excess commuting is still unknown. This study aims to explain how the position of city boundaries changes the estimation of excess commuting. A case study of the Daegu and Gwangju areas provides an ideal example for examining the subtle variations in the excess commuting estimates. The effects of changing city boundaries on the results of excess commuting are examined in relation to the discussion of monocentricity and polycentricity. Based on the results, this study argues that considerable variation in excess commuting in the previous literature needs to be understood in relation to different spatial structure and MAUP.
