你用deap2.1来处理，结果如下
Results from DEAP Version 2.1

Instruction file = eg1-ins.txt
Data file = EG1.txt

Input orientated DEA

Scale assumption: VRS

Slacks calculated using multi-stage method

EFFICIENCY SUMMARY:

firm crste vrste scale

1 1.000 1.000 1.000 -
2 1.000 1.000 1.000 -
3 1.000 1.000 1.000 -

mean 1.000 1.000 1.000

Note: crste = technical efficiency from CRS DEA
vrste = technical efficiency from VRS DEA
scale = scale efficiency = crste/vrste

Note also that all subsequent tables refer to VRS results

SUMMARY OF OUTPUT SLACKS:

firm output: 1 2 3
1 0.000 0.000 0.000
2 0.000 0.000 0.000
3 0.000 0.000 0.000

mean 0.000 0.000 0.000

SUMMARY OF INPUT SLACKS:

firm input: 1 2 3
1 0.000 0.000 0.000
2 0.000 0.000 0.000
3 0.000 0.000 0.000

mean 0.000 0.000 0.000

SUMMARY OF PEERS:

firm peers:
1 1
2 2
3 3

SUMMARY OF PEER WEIGHTS:
(in same order as above)

firm peer weights:
1 1.000
2 1.000
3 1.000

PEER COUNT SUMMARY:
(i.e., no. times each firm is a peer for another)

firm peer count:
1 0
2 0
3 0

SUMMARY OF OUTPUT TARGETS:

firm output: 1 2 3
1 200.000 15.000 35.000
2 220.000 18.000 45.000
3 210.000 17.000 20.000

SUMMARY OF INPUT TARGETS:

firm input: 1 2 3
1 15.000 20.000 50.000
2 14.000 23.000 51.000
3 16.000 19.000 51.000

FIRM BY FIRM RESULTS:

Results for firm: 1
Technical efficiency = 1.000
Scale efficiency = 1.000 (crs)
PROJECTION SUMMARY:
variable original radial slack projected
value movement movement value
output 1 200.000 0.000 0.000 200.000
output 2 15.000 0.000 0.000 15.000
output 3 35.000 0.000 0.000 35.000
input 1 15.000 0.000 0.000 15.000
input 2 20.000 0.000 0.000 20.000
input 3 50.000 0.000 0.000 50.000
LISTING OF PEERS:
peer lambda weight
1 1.000

Results for firm: 2
Technical efficiency = 1.000
Scale efficiency = 1.000 (crs)
PROJECTION SUMMARY:
variable original radial slack projected
value movement movement value
output 1 220.000 0.000 0.000 220.000
output 2 18.000 0.000 0.000 18.000
output 3 45.000 0.000 0.000 45.000
input 1 14.000 0.000 0.000 14.000
input 2 23.000 0.000 0.000 23.000
input 3 51.000 0.000 0.000 51.000
LISTING OF PEERS:
peer lambda weight
2 1.000

Results for firm: 3
Technical efficiency = 1.000
Scale efficiency = 1.000 (crs)
PROJECTION SUMMARY:
variable original radial slack projected
value movement movement value
output 1 210.000 0.000 0.000 210.000
output 2 17.000 0.000 0.000 17.000
output 3 20.000 0.000 0.000 20.000
input 1 16.000 0.000 0.000 16.000
input 2 19.000 0.000 0.000 19.000
input 3 51.000 0.000 0.000 51.000
LISTING OF PEERS:
peer lambda weight
3 1.000

另外我想说的是：按照通用约定你的决策单元个数太少，不适合用DEA处理
希望对你有帮助希望你采纳！
