20世纪80年代末的新自由主义改革促使拉美国家从高度保护的进口替代发展模式向开放型的外向发展模式转变,拉美国家的经济开放度不断提高。本文通过贸易开放度和投资开放度两个指标测算了拉美主要国家的经济开放度,并在此基础上,运用VAR模型实证研究了拉美主要国家经济开放度与经济增长之间的关系。结果表明,在不同的拉美国家,贸易开放度和投资开放度对经济增长的作用存在较大的差异。进一步动态分析结果表明,在考察拉美国家贸易开放度、投资开放度对经济增长作用时,有必要区分不同的时段。
The neoliberal reforms of the late 1980s led Latin American countries to shift from a highly protected import-substitution development model to an open-oriented export-oriented development model. The economies of Latin American countries are opening up more and more economically. Based on this, we use VAR model to study the relationship between economic openness and economic growth in major Latin American countries. The results show that in different Latin American countries, there is a big difference in the role of trade openness and openness in investment in economic growth. Further dynamic analysis shows that it is necessary to distinguish between different time periods when examining the openness of trade between Latin American countries and the role of investment openness in economic growth.
