Abstract: Based on social network analysis, this paper analyzes the structural characteristics of trade networks along the “Belt and Road” in 20082018, empirically tests the impact of the centering location of the trade network on technological progress, and analyzes the heterogeneity of countries with different income levels. The results show that the overall trade structure of the countries along the “Belt and Road” is relatively loose. Italy, Turkey, Korea, Russia, China and Singapore are located at the core of the network, and there are 23 countries (regions) playing “intermediary” or “bridge” roles, influencing the trade links among the remaining countries. More than 40% of the countries (regions) have strong indirect trade relations with nontrading partners. The promotion of centering position of the trade network would significantly promote the technological progress of the home country. The marginal impact of indirect trade on the technological progress is greater than that of direct trade. The direct and indirect trade centrality and the trade intensity in highincome and middleincome countries have a significant and positive impact on technological progress, and the trade intensity in lowincome countries also promotes the technological progress of home countries.

Key words: “Belt and Road”, trade networks, technological progress, social network analysis

摘要: 本文采用社会网络分析法探讨了2008—2018年“一带一路”沿线国家贸易网络结构特征,测算沿线国家贸易网络中心位置对技术进步的影响,并对不同收入国家进行异质性分析。研究发现:“一带一路”沿线国家整体贸易结构比较松散,意大利、土耳其、韩国、俄罗斯、中国和新加坡等国家(地区)位于网络核心,共有23个国家(地区)发挥“中介”或“桥梁”作用,影响着其余沿线国家之间的贸易联系;超过四成的沿线国家(地区)与非贸易伙伴国具有较强的间接贸易关系。贸易网络中心位置的提升能显著促进母国技术进步,间接贸易影响母国技术进步的边际效应大于直接贸易;中高等收入水平国家直接和间接贸易地位和贸易强度的提升均显著促进了技术进步,低等收入国家贸易强度的提升也能促进母国的技术进步。
