基于GTAP模型以六大经济走廊建设为例分析了"一带一路"倡议下提高贸易便利化的国际经贸影响。研究发现:一是"一带一路"六大经济走廊建设增加了贸易便利化提高国家的GDP,走廊沿线国家的GDP增加百分比均大于中国,其中中国-中亚-西亚经济走廊增加百分比最多;二是"一带一路"六大经济走廊建设对中国和走廊沿线国家均有福利改善作用,改善大小几乎相同,其中中国-中亚-西亚经济走廊福利增加最大;三是"一带一路"六大经济走廊建设增加了贸易便利化提高国家的出口总量,除了新亚欧大陆桥经济走廊之外,其他经济走廊沿线国家的出口总量增加百分比显著高于中国。

Research on the impact of trade facilitation on international trade——An empirical analysis based on the six economic corridors under the Belt and Road

Based on the GTAP model, this paper used the construction of six economic corridors as an example to analyze the impact of trade facilitation on international trade along the Belt and Road. The study found that:first, the construction of the six economic corridors along the Belt and Road has increased trade facilitation and improved the GDP of countries, the percentage of GDP increase in the countries along the corridor is greater than that of China, of which the China-Central Asia-West Asia Economic Corridor has the largest increase;Second, the construction of the six economic corridors along the Belt and Road has improved the welfare of China and the countries along the corridor, and the improvement is almost the same. Among them, the welfare of China-Central Asia-West Asia Economic Corridor has increased the most;third, the construction of the six economic corridors along the Belt and Road has increased trade facilitation and improved the total export volume of countries. Except for the New Eurasian Land Bridge, the percentage of increase in the total export volume of other countries along the economic corridor is significantly higher than that of China.
