Abstract: 情境相依之總要素投入效率分析法,結合了情境相依DEA分析(Context-dependent DEA)與總要素投入效率指標(Total-factor input efficiency)。它同時包含了兩者的優點,因此我們可以在分析不同的總要素投入效率的同時,將決策單位(DMUs)分類到不同的效率層級,來進行效率評估。為了展示如何應用此方法,我們採用了25家分別來自臺灣、南韓、日本及中國的顯示器製造商於2010年至2014年的資料,我們分別使用3種效率指標來做情境相依之DEA分層分析,其包含:整體技術效率、總資產的總要素投入效率及總研發支出的總要素投入效率。結果顯示,在採用不同的效率指標下,各個決策單位所位於的層級也有所不同。
The context-dependent total-factor input efficiency is an approach combing context-dependent DEA and the concept of total-factor input efficiency. It incorporates the advantages of both context-dependent DEA and total-factor input efficiency such that we can evaluate the DMUs by dividing them into specific levels and realize the disaggregate input efficiency. To illustrate this approach, we use the data of 25 manufacturers of display industry from Taiwan, Korea, Japan, and China, for the period from 2010 to 2014. The results show that the level rankings are different under the three measurements: overall technical efficiency (OTE), total-factor input efficiency (TFIE) of total assets, and total-factor input efficiency (TFIE) of R&D expenses.
