“交通强国”背景下中国中间品出口贸易影响研究

Study on the Influence of China's Intermediate Goods Export Trade under the Background of Transportation Infrastructure

以中国对“一带一路”沿线54个国家的中间品出口贸易为研究对象,探讨交通基础设施对中国中间品出口贸易产生的影响。研究结果显示:“一带一路”沿线国家交通基础设施总量指标对中国中间品出口贸易起显著的促进作用;不同类型的交通基础设施分量指标对中国中间品出口贸易的作用方向不一致,作用大小不相同;随着中国中间品出口贸易的扩张,交通基础设施总量指标的边际效应趋于平稳上升,各分量指标的边际效应存在异质性。

Taking China's export of intermediate goods to 54 countries along the"Belt and Road"as the re‐search object,this paper discusses the impact of transportation infrastructure on China's export of intermediate goods.The results show that the total transportation infrastructure index of countries along the"Belt and Road"plays a significant role in promoting China's export of intermediate goods;The effects of different types of trans‐portation infrastructure components on China's export of intermediate goods are different in direction and magni‐tude.With the expansion of China's export of intermediate goods,the marginal effect of total transportation infra‐structure index tends to rise steadily,and there is heterogeneity in the marginal effect of each component index.
