Abstract

This study analyzed profitability in pros and cons of owners about Garibong Urban Redevelopment District. Logistic Regression Model was performed as step 1 to analyze determinants that affect pros and cons, and a data-mining technique called decision tree analysis (CRT) was done as step 2 to investigate the decision tree structure. As a result of analysis, factors that affect pros and cons of owners were found to be residential location as personal characteristic, rent income, property and share of expense as economic characteristics, and building use as physical characteristic. On the contrary, age and physical characteristics such as land area, frontage condition and aged building did not show effects. Among determinants analyzed, change of residential location had greatest influence on change of decision, and owners placed priority on payment of additional share of expense when deciding pros and cons. Summarizing the results, whereas criteria for designation of urban redevelopment districts are physical factors such as deterioration and frontage condition, owners made project decision based on residential and economic characteristics. Many redevelopment districts were designated without consideration on characteristics preferred by owners.
