ABSTRACT: Because we still lived in a world called “Era of energy” and fossil fuel remained leading role in energy consumption, energy become core issues of economic development relationship. So the situations of world energy have attracted much attention. This paper establish Three-variable model contained energy intensity, import market concentration and the dependence to study the effect relationship between import market intensity, the dependency and energy intensify. The co-integration test shows co-integration among variables based on the data between 1980 and 2013. Furthermore, Granger causality test shows that the long-term and short-term remain positive from the affection of energy import market concentration to energy intensify. And the short term are positive but long-term not from the affection of energy intensify to energy import market concentration, the same relationship with energy intensify to import market concentration and energy import dependence to import market concentration. All those results could show direction for Korea energy strategy, meanwhile, offer some experience reference and advices for China’s energy strategy which own familiar energy status with Korea.
Keywords : Energy intensify; Import market concentration; Import dependency; Granger causal relation test.
