贸易条件是衡量一国贸易利益得失的重要指标。本文在南北贸易模式中讨论了南方国家贸易条件。研究发现,南方国家贸易条件是否随着劳动生产率提高而恶化,依赖于南方国家是否具有垄断定价能力。我国贸易条件实证分析表明,1997年之前贸易条件主要受到我国人均国民收入提高的影响而不断改善,1997年后随着劳动生产率提高,我国贸易条件不断恶化。
Terms of trade are important indicators of a country’s trade gains and losses. This article discusses the trading conditions in the South countries in the North-South trade model. The study found that whether the terms of trade in the southern countries worsened with the increase of labor productivity depend on whether the southern countries have monopoly pricing power. The empirical analysis of China’s terms of trade shows that before 1997, the terms of trade were mainly affected by the improvement of China’s per capita national income and improved continuously. As the labor productivity increased after 1997, the terms of trade in our country deteriorated continuously.
