Since China has the extremely wide land area, study of equilibriating the interregional energy demand/supply is a more practical subject than that of national total energy. demand/supply. However, the natural energy resources are located mainly in the undeveloped northwestern inland area, therefore, the energy demand/supply in the southeastern coastal area strongly depends on the long distance transportation. In the present study, an interregional general equilibrium model has been constructed for China's energy issues, and then the growth of energy demand/supply has been calibrated by region and by sector. Moreover restriction on the capacity of long distance transportation is examined calibrating the its effects on the interregional and intersectoral linkages.
