A Study on Relative Efficiency Evaluation on Facilitated Tomato Farms Using Data Envelopment Analysis and Malmquist Productivity Index

The following research analyzed the factors which influence the productivity along with relative efficiency evaluation on facilitated tomato farms from 2008 to 2012 year, measuring DEA and Malmquist Productivity Index. The major analytical results are as follows. First, according to efficiency evaluation using DEA model, average total technical efficiency was 0.902 and pure technical efficiency was 0.953. Second, dynamic analysis results using MPI showed retrogression in technical advancement degree which can produce higher calculation factors when fixed quantity of input elements are implemented. Especially, facilitated tomatoes of 2008 to 2012 year showed rapid decrease in productivity. Therefore, to enhance the productivity of facilitated tomatoes, political investment and support must be acquired for technical innovation. Third, in this research, the reason for 0.6% reduction in technical efficiency showed scale efficiency of 0.6% increase. However, net technical efficiency was reduced 0.6%. Therefore, to enhance productivity of facilitated tomatoes, net technical efficiency enhancement must be accompanied.
