Abstract

This study targets the urban park corresponding to the core areas (Hubs) of Green Infrastructure and estimates their value utilizing the Contingent Valuation Method (CVM) and determines the planning factors which affect them. The research aims to provide basic data for supporting the value improvement in the planning stage for urban parks representing green infrastructure. The primary purpose of this research is to derive variables that affect economic value and planning factors to improve the use-value of urban parks, one of the Hubs of the green infrastructure. In this study, Sejong Lake Park, located in Sejong City, is the target site. This study collected the responses of 105 people by conducting a survey on the intention to pay for the use-value and the planning factors that affect it, targeting visitors to Sejong Lake Park. The study conducts Contingent Valuation Method (CVM) on this survey responses. The results are as follows: first, as a result of analyzing the variables which affect willingness to pay for use-value, residence and age influence the willingness to pay significantly among socioeconomic characteristics. Next, the survey responses of Double-bounded dichotomous choices (DB-DC) CVM are converted into variables through statistic techniques. Furthermore, the variables are used for a Logit model to draw coefficients. The average willingness to pay per person for the use-value of Sejong Lake Park using the derived coefficients was approximately found to be 8,597 won. Therefore, as of 2019, Sejong Lake Park, with a total of 430,000 visitors, is estimated to have an annual economic value of 3.7 billion won. Third, the average Likert scale of the planning factor affecting the decision to pay for the economic value of Sejong Lake Park was the highest along the waterfront landscape, and the convenience facilities and waterfront landscape showed the highest willingness to pay, 10,000 won. In the range between 2,500 won and 5,000 won, the waterfront area ranks highest. Therefore, it can be said that visitors to Sejong Lake Park take account of the economic value of using the waterfront landscape the most. This study is meaningful as a thesis on use-value and the planning factors that affected value evaluation results of urban parks, and the analysis of the correlation between the planning factors of urban parks as hubs located in urban areas.

본 연구는 그린인프라의 핵심지역(Hubs)에 해당되는 도시공원을 대상으로 조건부가치측정법(CVM)을 활용한 가치추정 및 이에 영향을 미치는 계획 요소 도출을 통하여 도시공원에 대한 가치 향상 및 계획 단계에서 활용될 수 있는 기초자료를 제공하기 위하여 연구를 진행하였다. 주요 목적은 첫째, 경제적 가치에 영향을 미치는 변수를 도출하고, 둘째, 그린인프라의 핵심지역인 도시공원의 이용에 대한 경제적 가치를 추정하며, 셋째, 이러한 가치의 향상을 위한 계획요소를 도출하는 것이다. 본 연구에서는 그린인프라의 핵심지역 중 세종시의 도시공원을 대표할 수 있는 세종호수공원을 대상지로 선정하여 방문객들을 대상으로 세종호수공원의 이용적 가치에 대한 지불의사금액과 이에 영향을 미치는 계획요소에 관한 설문조사를 통해 수집된 105개의 응답결과를 바탕으로 조건부가치측정법(CVM)을 이용해 연구를 진행하였으며 그 결과는 다음과 같다. 첫째, 세종호수공원의 이용적 가치에 대한 지불의사에 영향을 주는 변수를 분석한 결과, 세종호수공원 방문객의 사회경제적 특성에서는 거주지, 연령이 이용적 가치에 대한 지불의사에 유의한 영향을 나타냈다. 둘째, 이중양분선택형 질문의 응답 결과를 통계적 기법으로 변수화하여 로짓모형으로부터 도출된 계수를 활용한 세종호수공원의 이용적 가치에 대한 1인당 평균 지불의사금액을 추정한 결과 8,597원으로 나타났다. 2019년 기준 세종호수공원의 총 방문객 약 43만명 고려시 세종호수공원에서 연간 발생하는 이용적 가치는 약 37억 원으로 추정된다. 셋째, 세종호수공원의 이용적 가치에 대한 지불의사 결정에 미치는 계획 요소의 리커트 척도 평균값은 수변공간이 가장 높게 나타났으며, 지불의사금액 10,000원에서는 편의시설이 가장 높게 나타났고, 지불의사액 5,000원 및 2,500원에서는 수변공간이 가장 높게 나타나, 방문객들이 수변공간을 이용하는 것에 대한 경제적 가치를 가장 크게 고려하는 것으로 볼 수 있다. 본 연구는 그린인프라 중 도시지역에 위치한 핵심지역에 해당되는 공원에 대하여 이용적 가치와 도시공원의 가치평가 결과에 영향을 준 계획요소, 그리고 계획요소간의 상관성 분석에 대한 논문으로서 의의를 가진다.
