Secondly, choose representative domestic and abroad petroleum price data and use cointegration test, Granger test, Error correction model and Grey relative coefficient methold to the domestic and abroad crude oil and fuel oil price and get the relations including cointegration, Granger cause, Dynamic equilibrium and time relations. Because domestic gasoline, diesel oil prices show rigidty phenomenon. Therefore, the analysis of domestic and abroad gasoline, diesel relations is not convenience by the analysis methods which are used to process the data of crude oil and fuel oil prices.
