Research on the short-term effects of Russia-Ukraine geopolitical conflict on the Europe energy security pattern
The change in geopolitical patterns triggered by the Russia-Ukraine conflict has posed a huge challenge to Europe.From the perspective of energy security,this study uses data from the monthly energy trade and GDELT(Global Database of Events)to investigate the short-term response to the geopolitical conflict between Russia and Ukraine.The results show that,from March to July 2022,the European energy reliance rate on Russia has reduced from 31.3％to 22.1％,implying that Russia declined in importance due to cuts in Russian oil and natural gas imports.In addition,this war produced different influences on different European countries,with an obvious"core-peripheral"spatial pattern,indicating that Eastern Europe faces greater energy security risks than Western Europe.During the war,the overall Herfindahl index of Eu-rope is still as high as 0.39,showing an over-concentration of energy supply,indicating that a potential risk to Europe's energy accessibility remains.Meanwhile,despite a rise of only 9％in energy imports,there was a 124％year-on-year rise in energy expenditure,which caused consid-erable concern about energy affordability.Findings in this study can be used to construct emer-gency management mechanisms for sudden changes in the short-term energy geopolitical pat-tern,and also provide policymakers with suggestions for long-term energy security and renew-able energy transition.
