During China's economic transition and development, owing to imbalance of regional economic development and segmentation of both labor and goods markets, consumers' behavior differs greatly, so that migration might have significant effects on the decision structure, and thus the behavior of those migrants from less developed areas. The empirical study on the cross-section data from Baise District, Guangxi, China, shows that migration does have significant effects on consumers' future expenditure plan and their objectives of saving. Additionally, the difference in consumers' behavior can also be explained by variables of household characteristics, household income, and their expectation of household income. This paper has provided evidence for evolution of consumer behavior and new policy foundation of deregulating interregional migration.
