Central Place Theory and the Emergence of Floating Markets in the Mekong Delta of Vietnam

Abstract

This research re-examines Walter Christaller (1933)’s central place theory paradigm to explain the emergence of a network of floating markets in the Mekong River Delta’s dense network of rivers and canals. Because road transportation is underdeveloped, floating markets play an important role for local people. They provide access to transportation and opportunities to trade, especially for the region’s diverse agricultural products. Furthermore, the floating markets support inland infrastructures. This research challenges Christaller’s (1933) assumptions about population thresholds and geographical range, and Mulligan et al.’s (2012) understanding of interaction among consumer choices, company aggregation and functional hierarchy. It finds that riverine traders employ flexible transaction strategies.
