国家规模对贸易投资便利化的影响——基于“一带一路”沿线国家数据的实证分析

以"一带一路"53个沿线国家为研究对象测算贸易投资便利化水平,并运用面板数据模型分析国家规模对贸易投资便利化的影响。研究发现：第一,2013年后,"一带一路"沿线国家的贸易投资便利化水平呈上升趋势。第二,在总样本和分时段样本中,国土规模对"一带一路"沿线国家的贸易投资便利化均具有显著的负向影响。第三,在分时段样本中,"一带一路"倡议提出前,居民收入规模是贸易投资便利化的重要影响因素,而倡议的实施使得贸易投资便利化不再受居民收入规模的影响。第四,在分区域样本中,各变量对贸易投资便利化的影响存在较大差异。基于此,本研究从国家规模的角度为"一带一路"沿线国家贸易投资便利化条件的改善以及中国在"一带一路"沿线国家的直接投资和双边贸易提出建议。

The Effect of Country Size on Trade and Investment Facilitation:-An Empirical Study based on “One Belt,One Road” National Data

Based on the "One Belt, One Road" national data, this paper choose 53 countries to calculate the trade and investment facilitation level, and then uses the panel data model to analyze the impact of country size on trade and investment facilitation. Our findings show that trade and investment facilitation level of countries along "One Belt And One Road" presented an upward trend after 2013. What's more, in the time-sharing sample, the scale of resident income was an important factor influencing trade and investment facilitation before "One Belt, One Road" initiative was proposed, and the implementation of the initiative made trade and investment facilitation no longer affected by scale of resident income. From the perspective of national scale, this study aims to improve the trade and investment facilitation conditions of countries which go along with "One Belt, One Road" initiative, it also make some suggestions for china in direct investment and bilateral trade.
