This study aims to propose a new measuring system of commercial gentrification to detect and gauge prevalence of commercial gentrification in neighborhoods across South Korea. First, we define the concept of commercial gentrification. Based on domestic and international literature review, we develop indicators of commercial gentrification. Demonstration of our measuring system is presented for unsan-si and Gongju-si. For public use, a measuring system is proposed to provide the public and other gentrification researchers with agent, data source, applicable spatial area, indicator update timeline, and relevant statistical database of individual indicators. We conclude by emphasizing use of our indicators and measuring system and suggesting policy and program improvements.
