Competitive Comparison Analysis in Appraisal Firms Relative to Different Levels of Efficient Frontiers

Context-Dependent DEA is a methodology for recognizing the efficient frontier of DUMs (Decision Making Units). Context-dependent DEA refers to a DEA approach where a set of DMUs are evaluated against a particular evaluation context. Each evaluation context represents an efficient frontier orgainzed by DMUs in a particular performance level. The context-dependent DEA measures the attractiveness when DMUs place on exhibition of poorer performance and the progress when DMUs place on of exhibition better performance as the evaluation group. This research applied the context dependent model to make the competitiveness of 12 appraisal firms on the continuous line of the existing Shin Yeon-Soo (2018) research. During each year it is important to know how the 12 appraisal firms will be classified according to the efficiency frontier and where each should belong. Efficient frontier categories are divided into five in 2010, four in 2011, five in 2012, five in 2013, three in 2014, seven in 2015 and four in 2016. Korea (DMU 12) received the highest score, Daehwa (DMU 8) and Hana (DMU 11) were more than 600. Next, Pacific (DMU 10), Joongang (DMU 4) and Samchang (DMU 7) were more than 450, Thefirst (DMU 2), Nara (DMU 1) and Miraesaehan (DMU 6) were more than 400. Finally Kyungil (DMU 5) and Daeil (DMU 3) were more than 300 while Gaon (DMU 9) has the lowest score.
