人口结构红利、数量红利与贸易增长：基于世界141个经济体面板数据的分析

Based on the extension and development of existing theories, this paper uses 141 countries' data of total savings rate, total population, trade competitive power index, GDP from 1975 to 2011, to build a panel-data econometric model, testing the population structure, population scale's effect on trade advantage. The results show that the scale effect of population quantity would help to reduce labor costs and increase export competitiveness; larger percentage of working population, lower burden of raising results in high saving rate, which has a long-term influence on the trade advantage as well. This paper argues that the advantage of population structure and quantity can promote the trade advantage when demographic dividend disappeared. Thus we suggest China to keep trade advantage base on the result.
