This study applied the Data Envelopment Analysis (DEA) as a relatively efficient measurement for obtaining the results of the nations participating in the last five Asian Games. The focus was on the productivity changes of Chinese Taipei Olympic Committee since its return from Beijing 1990 to Doha 2006. We used the time series analysis to compare Chinese Taipei’s decreasing ranking which were the 9th in Beijing, the 11th in Hiroshima and Bangkok, the 17th in Busan, and the 16th in Doha. The cross section analysis found out not only Chinese Taipei's benchmarking in Korea, Qatar and Kazakhstan, but the decrease in scale in the five competitions. Thus the increasing efficiency and effectiveness were two major thoughts for the Chinese Taipei Olympic Committee. Since Chinese Taipei's return to the Asian Games in 1990, it has assumed unstable productivity changes: Hiroshima 0.999; Bangkok 1.444; Busan 0.528; and Doha 0.612. It performed up-and-up in Hiroshima, the best in Bangkok, but rapidly at low ebb in Busan and Doha. The Chinese Taipei government, sports manpower ought to pay attention to it. In the bargain, the empirical analyses figured out that the hosted nations such as Japan, Thailand, and Korea created an extraordinary total productivity factor. The "home team advantages" promoted the entire nation's competitive capabilities and provided an important consultational direction for the rising competitive nations.
