Abstract

In this paper, we study a sample design for survey on goodwill in retail properties to provide a protecting policy for small traders and tenants, to use basic data for a dispute case related to goodwill. Since goodwill in retail properties is occurred by individual rent company, we use the census on establishments from the Statistics Korea as population. First of all, we consider preferentially seven metropolitan cities in which there are more than half of population. Total sample size is decided as 8,000. We allocate the sample size for markets as stratum in each city using proportional formula and the sample size for industrial classifications in each market using root proportional formula. Also we compute survey weights and calculate estimators, standard errors and interval of estimators for each characteristic such as type of establishments and market in seven metropolitan cities.

본 연구는 소상공인과 임차상인 보호정책을 지원하고, 권리금 분쟁소송 등에 참고자료로 활용할 뿐만 아니라 상가권리금 현황 파악을 위한 최초 조사를 실시하기 위한 표본설계 연구이다. 개별 임차 사업체 단위로 발생하는 권리금의 특성상 통계청의 전국사업체조사를 모집단으로 활용 하였으며, 우선적인 정보 제공이 필요한 7개 도시지역을 반영하였다. 전체 표본수는 8,000개로 하였으며, 7개 도시지역을 부차모집단으로 하고 지역별 상권별 표본수는 비례배분 하였으며, 상권내 업종은 제곱근비례배분 하였다. 목표오차를 활용하여 최종 표본수를 조정 하였으며, 표본설계가중치를 이용한 권리금 평균 추정량과 추정오차, 구간추정 공식을 유도하였으며, 이를 통해 도시별 상권별 및 업종별 통계 추정과 추정의 정도에 대한 평가를 가능하게 하였다.
