This paper provides the concept of import dependence between countries, which is a relative quantity. In order to reveal the evolutionary characteristics of the import dependence between countries in energy trade and its influencing factors, firstly, based on the network analysis method, this paper constructs a model of energy import dependence network (EIDN) among countries and regions along the Belt and Road (B&R countries). Crude oil and natural gas are taken as empirical objects, and the evolution characteristics of the two kinds of EIDNs are analysed. The result showed that most of the B&R countries had a small number of crude oil and natural gas trade partners. However, the import dependence in crude oil and natural gas trade between countries is relatively large, indicating that the risk of oil and gas security in B&R countries is high. Moreover, based on the QAP method, spatial distance, economic differences, the signing of free trade agreements, and the differences in energy consumption between countries have a significant impact on the import dependence in crude oil and natural gas trade among B&R countries.

能源进口依赖网络演变及其影响因素：以“一带一路”沿线国家和地区为例

本文提供了国家间进口依存度的概念，它是一个相对数量。为了揭示能源贸易国家间进口依存度的演化特征及其影响因素，首先，基于网络分析方法，本文构建了“一带一路”沿线国家和地区能源进口依存度网络（EIDN）模型。和道路（一带一路国家）。以原油和天然气为实证对象，分析了两种EIDN的演化特征。结果表明，大多数“一带一路”沿线国家的原油和天然气贸易伙伴数量较少。但各国间原油和天然气贸易的进口依存度较大，表明B&B的油气安全风险较大。R国家是高的。此外，基于QAP方法，空间距离、经济差异、自由贸易协定的签署以及国家间能源消费的差异对“一带一路”沿线国家原油和天然气贸易的进口依存度有显着影响。
