摘要：
This paper adopts two mathematical approaches, data envelopment analysis (DEA) and grey relation analysis (GRA) to measure DEA efficiency using the sample of 69 listed US internet companies. A total of 40 indicators were initially selected for the efficiency evaluation, with 21 related to DEA-input indicators and 19 to DEA-output indicators. Eight representative indicators selected using GRA are subsequently used as the input and output indicators in the DEA analysis. The empirical result also shows that 10 out of 69 dot com firms are CCR-efficient in DEA Efficiency.
