1 單元七 非參數法衡量生產力變化之 電腦實習 An Output-orientated VRS Malmquist DEA Example：資料檔(Eg1.dta) Y X X2 …………………………………. ….共三期, 每期22筆資 料, 因此共66筆資料

2 程式檔(Eg1.ins) Eg1.dta DATA FILE NAME Eg1.out OUTPUT FILE NAME
NUMBER OF FIRMS NUMBER OF TIME PERIODS NUMBER OF OUTPUTS NUMBER OF INPUTS =INPUT AND 1=OUTPUT ORIENTATED =CRS AND 1=VRS =DEA(MULTI-STAGE), 1=COST-DEA, 2=MALMQUIST-DEA, 3=DEA(1-STAGE), 4=DEA(2-STAGE)

3 結果檔(Eg1.out) Results from DEAP Version 2.1 Instruction file = Eg1.ins
Data file = Eg1.dta Output orientated Malmquist DEA DISTANCES SUMMARY year = 1 firm crs te rel to tech in yr vrs no ***************** te t t t+1 ……………………………………. mean

4 year = 2 firm crs te rel to tech in yr vrs no ************************ te t t t+1 ……………………………………. mean year = 3

5 ……………………………………. mean [Note that t-1 in year 1 and t+1 in the final year are not defined] MALMQUIST INDEX SUMMARY year = 2 firm effch techch pech sech tfpch ………………………………………. mean

6 year = 3 firm effch techch pech sech tfpch ………………………………………. mean MALMQUIST INDEX SUMMARY OF ANNUAL MEANS year effch techch pech sech tfpch mean

7 MALMQUIST INDEX SUMMARY OF FIRM MEANS
firm effch techch pech sech tfpch ………………………………………. mean [Note that all Malmquist index averages are geometric means]

8 作 業 求算民國75~80年、80～85年間Malmquist生 產力變動指數、技術水準變動、純粹管理技 術效率(PTE)變動、規模效率(SE)變動,並說明 各期間每一縣市生產力變動之主要原因。
