| چکیده | ||
| پبچیدگی فزاینده الگوی تجارت جهانی نفت یکی از مهمترین عوامل تأثیرگذار بر راهبرد انرژی و توسعه اقتصادی هر کشور، به خصوص کشورهای صادرکننده نفت مانند ایران، است. در این مقاله، ویژگی‌های کلی، ویژگی‌های منطقه‌ای و استحکام تجارت نفت با استفاده از نظریه شبکه برای 178 کشور در سال 2018 تجزیه و تحلیل شده است. نتایج حاکی از آن است که شبکه صادرات نفت توزیع مقیاس آزاد دارد بدین معنا که موقعیت تجاری کشورها ناهمگونی آشکاری را نشان می‌دهد. به علاوه، شبکه تجارت جهانی نفت ویژگی «مستحکم اما در عین حال شکننده» دارد. همچنین شبکه تجارت جهانی نفت به سه بلوک تجاری شامل بلوک مرکزی و شرقی تجاری، بلوک میانی تجاری و بلوک غربی تجاری قابل تقسیم است. در بین این سه بلوک تجاری، بلوک مرکزی و شرقی توانسته است بیشترین میزان تأمین تقاضای کشورهای حاضر در این بلوک را تأمین کند و بنابراین این کشورها از کمترین تکانههای عرضه نفت برخوردار میشوند. | ||

| چکیده [English] | ||
| The increasing complexity of the global oil trade significantly affects the energy strategy and economic development of countries, particularly those that export oil, such as Iran. This paper analyzes the general characteristics, regional features, and strength of the oil trade using network theory for 178 countries in 2018. The results show that the oil export network has a free-scale distribution, which means that the commercial position of countries displays significant heterogeneity. Additionally, the global oil trade network has a "robust yet fragile" characteristic. The global oil trade network can be divided into three commercial blocks, including the central and eastern commercial block, the middle commercial block, and the western commercial block. Among these three commercial blocs, the central and eastern bloc can supply the highest amount of demand from the countries present in this bloc. Consequently, these countries receive the lowest oil supply impulses. | ||
