摘要：From the situations about the incomes and life quality of the urban and rural residents, the thesis briefly introduces the status quo of the urban-rural income gap and explores the impact of the income gap on social economy: firstly, it hampers economic development; secondly, it is detrimental to the social development. Then the thesis analyzes the role of a sound social security in narrowing urban-rural income gap: at first, it broadens the institutional environment of improving the agricultural efficiency; secondly, it eliminates the uncertainties influencing the farmers’ income; thirdly, it improves the farmers’ capacity to increase income; at last, it enhances the farmers’ consciousness of wealth.
