开放经济下的索洛模型与经济增长的“美国模式”

开放经济下,投资率并不完全由储蓄率决定。以美国为例,尽管国内储蓄投资缺口长期存在,但仍然可以通过借入储蓄的方式为缺口融资,支持投资和经济的增长。尽管日趋严重的"双赤字"已经成为制约美国经济持续发展的掣肘,但反观我国当前经济存在的若干问题,这种与我国成鲜明对比的经济增长模式以及与之相伴随的高人均收入、高社会福利的社会体制,仍不失值得我国借鉴之处。

Solow Model and America Developing Mode under Open Economy

Under an open economy,invest rate is not entirely decided by the saving rate.In the United states,for example,in spite of saving investment gap in the long term,it is still possible to borrow the savings to finance the gap for investment and economic growth.Although "twin deficits" have impeded the American economy,but to our current economic,the economic growth mode with high per capita income and high social welfare are still worth learning.
