| Summary: | 碩士 === 國立交通大學 === 經營管理研究所 === 104 === Utilizing a new data envelopment analysis method based on the concept of non-oriented DDF model, this article analyzes G7 and BRICS group’s efficiency scores of all variables and total factor productivity from both static and dynamic perspectives based on the panel data from 12 developing and developed countries from G7 and BRICS for the period of 2000 to 2010. In this paper, we then further decompose the total factor productivity index into two components (technical efficiency change and technology change) that provide a full analysis. The main findings are as follows: (i) the developing and developed countries are not very different in the efficiency of real capital and labors, showing that the traditional factors of production are not major factors any more in the country’s economic growth now. (ii) G7 countries have highest efficiency scores than BRICS countries with respect to energy use, real GDP and CO2 emissions, showing that there exists technology gap between them. (iii) G7 countries performed better than BRICS countries in TFP change. This difference between them is due to technology change instead of technical efficiency change.
