摘要
通过搜集包括107个国家1960~2010年的跨国面板数据集,采用系统广义矩方法估计,研究外债对经济增长的影响以及作用渠道。研究发现:总体上,外债对经济增长、投资增长以及全要素生产率均有显著的倒“U”形影响;发达国家的外债对经济增长的影响是负的,外债扩张可以促进投资增长,但同时会降低投资效率;发展中国家的外债对经济增长有显著的倒“U”形影响,对投资增长的影响也是倒“U”形的,而对全要素生产率的影响则不显著。
This paper compares the differences between developed and developing coun- tries in economic growth effects of external debt and the role of channels using a cross-coun- try data set. It finds that: the impact of external debt on economic growth, investment growth and total factor productivity are all inverted U-shaped; in developed countries, ex- ternal debt has negative effect on economic growth due to misallocation of resources, on the contrary, it facilitates investment growth; in developing countries, the influence of exter- nal debt on economic growth and investment growth are significantly inverted U-shaped, but the impact on total factor productivity is not significant.
