Technical, allocative, cost, profit and scale efficiencies in kedah, malaysia rice production: a data envelopment analysis

摘要

This study estimates profit and scale efficiency using profit DEA model and technical, allocative, and cost efficiency using cost DEA model under both constant returns to scale (CRS) and variable returns to scale (VRS) respectively and subsequently the determinants factors were investigated based on the estimated efficiency using survey data of 70 rice farmers, Kedah, Malaysia. In case of profit efficiency, majority of the rice farmers were operating with increasing returns to scale 54.29%, 34.29% decreasing returns to scale and only 11.43% with constant returns to scale. In case of cost efficiency only 4.29% of the farmers were 100% technically efficient under CRS while it is increased into 16.90% under VRS. The average technical, allocative and cost efficiencies were estimated at 0.28, 0.878 and0.255 respectively under CRS while they were increased into 0.61, 0.883 and 0.533 respectively under VRS. In case of profit efficiency the performance measured in CRS and VRS are showing same while they are performing below average in both CRS and VRS in case of cost efficiency. The efficiency scores are regressed against the wage, disease control, production, income, farming system, cost, used in farming operations and discussed.
