概要 （英文）

THIS PAPER DISCUSSES INTERFUEL SUBSTITUTION IN JAPANESE MANUFACTURING INDUSTIVES USING SECTOR DATA FOR ENERGY PURCHASE PRICES. SINCE ENERGY END-USE TECHNOLOGY AND SECTOR PURCHASE PRICES MAY BE HETEROGENEOUS ACROSS SECTORS AND THERE ARE COMPOSITIONAL CHANGES,SECTOR ANALYSIS WAS USED TO EXAMINE INTERFUEL SUBSTITUTION POSSIBILITIES. THE DATA FOR SECTOR PURCHASE PRICES FOR ENERGY,WHICH HAVE BEEN DEVELOPED FOR THE FIRST TIME IN JAPAN,SHOW SUBSTANTIAL DIFFERENCES ACROSS SECTORS. THE EMPIRICAL RESULTS OF THE TRANSLOG FACTOR SHARE MODEL FOR TOTAL ENERGY PURCHASES INDICATE THAT PURCHASED ELECTRICITY IS A SUBSTITUTE FOR GAS IN MACHINE INDUSTRIES,AND FOR COAL IN HEAVY INDUSTRIES. THE SUBSTITUTION POSSIBILITIES OF PURCHASED ELECTRICITY FOR GAS AND COAL IN THESE SECTORS REFLECT THE RECENT INCREASE IN COMPETITIVE FORCES SUCH ASTHE RAPID INCREASE IN SELF-GENERATED POWER. CONSIDERING INTRA-SECTOR HETEROGENEITY IN END-USE TECHNOLOGY,INTERFUEL SUBSTITUTION IN PROCESS HEAT IS ALSO EXAMINED. THE EMPIRICAL RESULTS SUGGEST THAT HEAVY OIL IS A SUBSTITUTE FOR ALL OTHER TYPES OF ENERGY IN PROCESS HEAT IN ALL SECTORS.
