This report examines the redistribution effect of government expenditure on household income or consumption by dividing government expenditure into three categories; pure public goods, specific public goods, and public transfers. We analyze the direct effect through taxes and transfers, the effect through public goods provision, and the effect through the support for housing, education, and health, respectively, by calculating the Gini index with a household survey data set. The change of Korea's inequality degree in a recent decade could be decomposed into net transfer, pure public goods, and non-pure public goods. Net transfer, which consists of taxes and transfer income, enhances income distribution due to the increase of government transfer. Pure public goods increases the Gini index, which deteriorates the distribution equality. On the other hand, specific public support for housing, education, and health strengthens the distribution equality. The distribution effect of each one dollar spent has the order of education, to housing, to health in 1999～2003.
