Ｔｒａｎｓｌｏｇ型生産関数理論の電気事業への適用

タイトル（英文）

AN APPLICATION OF THE THEORY OF THE TRANSLOGPRODUCTION FUNCTION TO THE JAPANESE ELECTRIC POWER INDUSTRY

概要 （図表や脚注は「報告書全文」に掲載しております）

この研究の目的は，Ｔｒａｎｓｌｏｇ型生産関数の理論を昭和３４年～５３年の期間の電気事業に適用し，この期間の電気事業における，生産要素間の代替・補充関係，生産要素需要の価格弾力性，技術進歩のタイプなどを定量的に分析することである。主な結果は次のとおりである。１生産要素（資本，労働，エネルギ－）間の代替弾力性は，多くのサンプルについて，すべて正となり，この期間において，これらの生産要素は，相互に代替的であった。２分析にＴｒａｎｓｌｏｇ型関数を用いることの妥協性が統計的に証明された。

概要 （英文）

THE PURPOSE OF THIS STUDY IS TO ESTIMATE THETRANSCENDENTAL LOGARITHMIC(TRANSLOG)COST FUNCTION OF THE ELECTRIC POWER INDUSTRY IN JAPAN.WE ESTIMATED THE TRANSLOG COST FUNCTIONS FOR THE NINE ELECTRIC POWER COMPANIES. FROM THE PARAMETER ESTIMATES,THE ALLEN PARTIAL ELASTICITIES(SIJ)ARE CALCULATED. SELS(ELASTICITIES OF SUBSTITUTIONBETWEEN ENERGY AND LABOR)RANGE FROM 0.12 TO 0.47 FOR THE ELECTRIC POWER COMPANIES,AND FROM 0.23 TO 0.52 FOR THEIR THERMAL PRODUCTION SECTORS.SLKS(BETWEEN LABOR AND CAPITAL)RANGE FROM 0.04 TO 0.52 FOR THE COMPANIES,AND FROM 0.35 TO 2.09 FOR THE THERMAL PRODUCTION SECTORS .AND SEKS(BETWEEN ENERGY AND CAPITAL)RANGE FROM 0.08 TO 0.90 FOR THE COMPANIES,AND FOR THE THERMAL PRODUCTION SECTORS. IN THE EARLIER STUDIES WHICH ESTIMATED ELASTICITIES OF SUBSTITUTION AMONG INPUTS IN INDUSTRIES OR COUNTRIES BY THE TRANSLOG FUNCTION METHODOLGY,SEL AND SLK WERE ESTIMATED TO BE POSITIVE(SUBSTITUTABLE).BUT SEK WAS POSITIVE IN SOME STUDIES AND NEGATIVE IN THE OTHERS.A CONTROVERSY WAS AROUSED ON THE SUBSTITUTABILITIES BETWEEN CAPITAL AND ENERGY,CONNECTED WITH THE PRACTICAL PROBLEM CONCERNING THE EFFICACY OF ENERGY SAVING INVESTMENT. OUR ESTIMATES OF SEL AND SLK ARE OF SAME SIGN AND OF SAME LEVEL OR A LITTLE LOWER LEVEL,COMPARING WITH THE ESTIMATES OF EARLIER STUDIES.AND SEKS ARE POSITIVE(SUBSTITUTABLE)IN OUR STUDY,AND THIS IS SAME AS THE ESTIMATES FOR ELECTRIC POWER COMPANIES IN THE UNITED STATES BY CHRISTENSEN AND CREENE.
