“…In the material procurement process in the modern e-commerce environment, how can the process be set up to complete the procurement task and adapt to the needs of the times? As an effective way to change the status quo of a company's procurement management, in the process of process reengineering, the flat procurement rules should be followed, and the material procurement process should be reengineered in the e-commerce environment [16].…”

Crude oil is the main raw material for the petrochemical industry and a major component of total production costs. It is also an indispensable resource for petrochemical enterprises. The implementation of crude oil e-commerce procurement by petrochemical enterprises can not only reduce the procurement cost of crude oil but also create good economic benefits in the field. It can also establish strategic partnerships with oil field enterprises to lay the foundation for the scientific development of enterprises. Based on the production of Company A and the “10 Million Tons Refining” project, this paper introduces the concept of e-commerce procurement for the problems in all aspects of crude oil procurement management. This paper deeply studies the e-commerce procurement theory, constructs the e-commerce procurement management implementation framework, and proposes that the scientific evaluation of crude oil suppliers is the key idea for petrochemical enterprises to implement enterprise e-commerce procurement management. At the same time, it also conducted an in-depth analysis of the internal and external environment of a company’s crude oil e-commerce procurement, conducted a comprehensive evaluation of existing crude oil suppliers and potential suppliers, and formulated corresponding procurement strategies. Results of the study show the success of the proposed study, and on the basis of the proposed study, researchers can devise new solutions in the field.

“…力 [114][115] ，中国在全球原油贸易中的控制能力在不断提升，由局部地缘供给依赖转变为多元共存的贸易模式 [110,[116][117][118] 。国际天然气贸易网络存在幂律性和群簇性，网络的异质化程度较高，局部表现出聚集性与核心-边缘结构 [119] 。液化天然气(liquefied natural gas, LNG)和管道天然气的进出口贸易网络均显示无标度分布，而 LNG 贸易网络中的国家与管道燃气交易网络的关联度更大，北美、欧洲和亚洲的市场尚未整合 [120] 。管道天然气贸易主要集中在欧亚大陆，其对战略通道具有路径依赖性和滞后性，区域资源禀赋是 "核心-边缘" 结构的主要成因 [121] 。 "一带一路" 倡议提出后，丝绸之路经济带沿线国家天然气贸易格局存在 "马太效应" ，俄罗斯、卡塔尔、新加坡和中国是天然气贸易的核心国 [122] ；然而天然气贸易互动并不明显，且由于外部环境的稳定性较差，核心-边缘结构不断发生着重组与变更 [123] 。此外，也有学者对世界天然气竞争网络、网络优化和模拟分别进行了研究 [124][125][126] [137] ， 2017 年全球水电净增长全部来自中国，全球在建核能中 40%来自中国 [138] 。学者们以太阳能和水能的贸易网络为切入点研究了全球新能源网络的变化特征，认为新能源网络比油气资源贸易更为复杂 [139] 。相比石油贸易，新能源贸易模式发生了变化，以中国为代表的发展中国家成为全球新能源贸易的核心 [137] 。学者们还通过综合能源网络研究，发现天然气贸易网络相比煤炭、石油网络具有更大的群落和稳定性 [140] ，太阳能光伏贸易比化石能源贸易要更为密集 [141] 。在综合能源网络中贸易集团和组织发挥着重要作用，亚太国家贸易集团具有不确定性 [142][143] 行集体行动，采取切实可行的能源政策 [145][146][147] 。然而能源利益相关主体的利益诉求不同、矛盾错综复杂，深陷能源霸权与能源主权利益之中，往往难以达成一致的治理方案 [148] 。因此全球能源治理表现为一个目标多元、主体分散、结构多层、机制碎化、领域交叉的治理网络 [149][150] ，且尚未形成综合性、权威性、有约束力的全球能源治理机制 [146] 。目前既有的能源治理平台与行动框架呈现出发展不成熟、区域化趋向和偏重消费方的实际不足，导致全球治理实践进展迟滞、参与主体有限、运行机制不畅的发展困境 [151] 。针对全球能源治理存在的问题，学者们 [10] 史丹. 全球能源格局变化及对中国能源安全的挑战 [Xu Qinhua.…”

“…Their findings revealed that Russia had a central role in the European system and Kazakhstan had a role as a secondary hub in Central Asia bridging between Europe and China. Du et al (2016) analyzed the topological properties of the world crude oil network. Their findings supported the fitness to power-law distribution.…”

The role of energy for the developmental process of nations is a known fact due to being crucial input for any phase of production of goods and services. That’s the reason why countries that are rich in energy resources also have strategic power in terms of the international trade of these resources. On the other hand, it becomes important to provide energy security for countries that are resource-poor. Although green energy has become preferred one, fossil fuel energy keeps its place as one of the most used energy resources. That's why in this study it is aimed to determine major providers and users of coal as a type of fossil fuel energy resources. It is vital to investigate the structure of global coal trade structure to determine the weaknesses and strength of supply and use of coal. Network approach provides a holistic view to the system analyzed and presents more realistic (high-degree) indicators to analyze it. In this study, global trade network of coal is analyzed from 2000 to 2017 via network analysis. Changing structure and evolution of global coal trade has been revealed via some topological parameters which are specific to complex networks such as density, clustering, assortativity/disassortativity, centrality and degree distribution.
