【摘要】 传统的凯恩斯财政乘数理论和现代财政理论,相继讨论政府支出乘数、税收乘数以及转移支付对产出的乘数效应,共同得出的结论是短期利用外债来拉动一国经济的增长可以取得较好的乘数效应,但长期内只能依靠国内的投资拉动。并且由于政府支出与转移支付对产出的效果影响不尽相同,所以国债对经济拉动的乘数作用既取决于国债来源结构,又取决于国债的投向结构。更多还原

【Abstract】 Traditional Keynesian multiplier of fiscal policy includes governmental expenditure multiplier and tax multiplier.Modem finance theory discussed the multiplied effect of the transfer payments to the output ulteriorly.jn principle, the author analyzed the factors of the short run which affect the effect of the national debt, as well as in the long run,then figured out that pulling the growth of the economy with the foreign loans in the short run will praduce good multiplied effect, but in the long run the economy growth can only depend on capitals of our own country. Because the effect to the output of the governmentd expenditure is different to that of the government transfer payment, the pulling effect to the economy of the national debt not only depends on the structure of the source of the national debt, but also depends on the outlet structure.更多还原
