ABSTRACT This paper compared the technical efficiency of the secondary energy industries of 16 countries and studied the factors that affect technical efficiency. The estimation results indicated that the average technical efficiency of all 16 countries has been stable in a high level since 1995. An analysis of the 1st half (1991-1997) and the 2nd half (1997-2005) of the analysis period showed that average technical efficiency was almost the same. Also, the 16 countries were classified into three groups - European countries, Asian countries and the Anglo-American countries - and analyzed. As a result, the high technical efficiency in Asian countries was noticeable and European and Anglo-American countries showed relatively stable trend. In addition, the factors determining technical efficiency were analyzed with labor (education level), capital (capital intensity) and technology (national R&D investment) as variables. The results showed that technical efficiency improved as capital intensity was higher, the portion of low-education population was lower and a national R&D amount was higher.
