Abstract The measurement of technical efficiency
and productivity growth in the agricultural sector of developing and
developed countries has received renewed attention in recent decades.
The use of frontier approaches such as the data envelopment analysis
(DEA) and stochastic frontier analysis (SFA) have become more popular
in efficiency and productivity measurement. The main purpose of this
study is to measure agricultural technical efficiency and total factor
productivity using DEA and the DEA-based Malmquist total factor
productivity (TFP) index in the South Marmara region of Turkey in the
period 1993–2002. An output-oriented DEA model is used for
estimating technical efficiency and the Malmquist TFP index of
agricultural sector with aggregate panel data in the South Marmara
region of Turkey. Calculated average technical efficiency score and
Malmquist TFP index for region in period 1993–2002 are 88.3 and
3.1%, respectively.
Keywords data envelopment analysis; technical efficiency; total factor productivity
