AN ANALYSIS OF U.S. INVESTMENT, TRADE AND GOVERNMENT BUDGET Wei Wei（42） This essay gives the author's perception of U.S. economy in three points. They are: (1) the domestic private investment will steadily grow and may fluctuate twice in the 1990s; (2) the foreign trade deficit will gradually fall off and be balanced out finally; and (3) the federal government cannot resolve its budget deficit in the 1990s.
