Abstract: With the rapid growth of shale oil industry in the U.S., crude oil trade pattern of the U.S.has changedThe proportion of heavy crude in the U.S.total crude oil imports has significantly increased and the concentration of its oil import sources has also been amplifiedThis paper investigates the underlying causes of the strategic change in the U.S.oil imports and proposes a complementary relationship between the domestic shale oil use and the imports of Canadian oil and a substitution relationship between the domestic shale oil use and the imports of oil from OPECThe results of cointegration test and Granger causality test have confirmed above hypotheses and provide some evidence for the interaction between the U.S.shale oil demand and crude oil imports from different importing partnersFinally, this study has important policy implications for China's shale oil strategy and the SinoU.S.crude oil trade relationship
