بررسی جایگاه و شدت رقابت تجارت برق ایران در منطقه غرب آسیا با استفاده از رویکرد تئوری شبکه

هدف: هدف مطالعه تعیین جایگاه و شدت رقابت تجارت برق ایران در منطقه غرب آسیا به منظور کمک به سیاست‌گذاری تجاری برق است. روش: به منظور تعیین جایگاه کشورها در شبکه تجارت برق و مشخص کردن منطقه مورد مطالعه، ابتدا شبکه تجارت جهانی برق با استفاده از تئوری شبکه، با درنظر گرفتن کشورها به عنوان گره و صادرات برق به عنوان لینک‌ برای هر سال طی دوره زمانی 2018-2010 ساخته شده و اجتماعات مختلف تشخیص داده شده‌اند. برای بررسی نقش هر کشور یا به اصطلاح گره در شبکه، شاخص‌های تمرکز محاسبه و تحلیل ‌شده ‌است. در گام دوم تحلیل رقابت‌پذیری با محاسبه شدت رقابت میان صادرکنندگان برق و ایجاد شبکه رقابتی با تعریف شدت رقابت به عنوان لینک صورت گرفته است.  یافته‌ها: یافته‌های حاصل از تحلیل شبکه تجاری نشان می‌دهند ایران هاب تجاری منطقه است. کشورهای ایران و ترکیه پیشروترین گره‌ها محسوب می‌شوند. ایران با کشورهای ترکیه، آذربایجان و روسیه برای حفظ سهم بازار در منطقه رقابت دارد. نتیجه‌گیری: نتایج تحلیل شبکه رقابتی نشان می‌دهد ایران مرکزی‌ترین گره شبکه بوده است؛ یعنی بیشترین رقابت با کشورهای منطقه را دارد. در نهایت، طی زمان رقابت و انسجام شبکه در منطقه در حال افزایش بوده است.

the importance and competition intensity of cross-border electricity trade of iran in west asia community, using trade network theory

objective: this study aims to model electricity cross border trade policy based on the network theory and to investigate the position and importance of west asia community in the global electricity trade network. the cohesion in the electricity trade between countries will ensure the security of electricity supply and reduce costs. west asia community is a group of countries in the network that includes iran. method: for this purpose, the global network is constructed to examine the role of each node in the network for the time period of 20102018. different communities are identified to proceed with the network analysis. we detect the communities based on the louvain method as it has the large zscores for all years and it’s an efficient algorithm. an innovative analysis is introduced; that is competitiveness to capture the competition intensity among electricity exporters. to capture the competition intensity between two electricity exporters, we use glick and rose (1999) suggested indicator. results of this study clearly show the influence and necessity of iran for stabilizing of the network within its community. iran mostly has electricity trade with seven of its neighboring countries, which are turkey, pakistan, iraq, afghanistan, turkmenistan, azerbaijan and armenia. among them, iran exports electricity to three countries, afghanistan, pakistan and iraq, and conducts bilateral trade with four other partners.the results of the competition intensity suggest more interconnectedness among community members, and show iran compete with turkey, azerbaijan and russia on the regional market share. the competition intensity trend, extracted from the competition networks, escalated during the time period. also iran is a key node of its community in the competition networks. finally, it is showed that electricity trade can be increased between iran and other regional partners. also based on all different kind of the centrality measures, iran is the most important node in these networks. all in all, the competition intensity networks for the region, depict intense competition among the nodes, and especially iran is considered to be the most central node, showing the highest competition relation with its partners. turkey in the first years and azerbaijan in the last years of the period are in second place in terms of the competition intensity (these extracted competition networks can be scrutinized in details that give researchers crucial information about the condition of export competition). conclusion: community of iran usually consists of iraq, afghanistan, pakistan, tajikistan, and uzbekistan, turkey and armenia. the position of iran within its community has been scrutinized. for the first part, among all, community of iran is in the middle ranking (for example, 8 and 10 among 16 and 15 communities in 2011 and 2018, respectively) based on the total weight. the share of weight of this community to the total trade, varies between 0.2% in 2015 to 14.7% in 2014. by conducting a measure for finding trade hubs in different communities, it’s been found iran had the greatest score and considered to be the trade hub in west asia region. its score in some years puts it among top five trade hubs in whole network (for 4 years).
