It is often said that an increase in autonomous imports will decrease the national income. Under what conditions it will be so is investigated in this paper, referring to articles by Stolper, Amuzegar, and Holzman and Zellner. The answer to this question is this: if autonomous imports substitute domestic consumption and/or investment, the national income decreases when imports autonomously increase, and if there are no substitution between imports and domestic expenditure, the national income does not change. Next the role of autonomous imports in the balanced trade multiplier is considered. Whether the national income increase by balanced increases in exports and autonomous imports depends export leakage coefficient, substitution coefficients of imported component to domestic one, and the share of import for consumption in total imports, or it depends the relative size of export leakage coefficient and weighted average coefficient of substitution. If and only if the former is larger than the latter, the national income will increase.
