Construction and thinking of BRICS energy trade security network system after membership expansion
Since 2020,the global energy pattern has entered an unprecedented period of transformation under the influence of various factors.As the global energy game and energy trade risks continue to be aggravated,the en-ergy security issues of BRICS countries will face great challenges.Therefore,it is urgent for BRICS countries to find effective ways to enhance the security of energy trade.First,this paper selects the panel data of BRICS countries after membership expansion from 2005 to 2021,constructs an energy security evaluation system from five dimensions:production reserve security,trade security,network and transmission security,consumption se-curity,and sustainability,and calculates the relative closeness of energy security level of each country through two tool methods:combined entropy weight method and TOPSIS method,and then ranks them.Secondly,based on the current international situation,this paper further designs the BRICS energy trade security early warning mechanism,predicts the future energy trade trend of BRICS countries,and avoids external risks by increasing the proportion of energy trade among BRICS countries.Finally,this paper proposes that the energy trade security level of BRICS countries can be implemented by selecting regional energy center countries and building energy trade security early warning mechanism.
