The aims of this paper are to analyze the correlation between the migrant household and national economic development, to find out the differences of income and expenditure among the migrant households, to compare the average income and expenditure of the origin with those of the destination, and to suggest the influences that affect the migrant household’s living quality. The study finds that,（1）the migrant households that moved from developing areas to developed areas still shared the benefits of the national development;（2）the relative level of income and expenditure of the migrant households are seriously influenced and their living quality is actually reduced due to the great differences in different regional economic development;（3）The pension increase system, the household registry reform system, and the intergenerational filial piety have partly slowed down the negative impact on the migrant household;（4）it is no clear that how the change of the family structure affects the migrant household’s living standard. A balanced consideration of economic, social, cultural factors is required.
