National saving -- the portion of a nation's current income not consumed -- is the sum of saving by households, businesses, and all levels of government. National saving represents resources available for investment to replace old factories and equipment and to buy more and better capital goods. Higher saving and investment in a nation's capital stock contribute to increased productivity and stronger economic growth over the long term."
