해양보호생물인 거머리말의 보전에 대한 대중의 지불의사액 - 조건부 가치측정법의 적용 = Public Willingness to Pay for the Preservation of Marine Protected Species Zostera marina: A Contingent Valuation Study

다국어 초록 (Multilingual Abstract)

Zostera marina (ZM), a type of seagrass registered as a marine protected species in South Korea, provides valuable ecosystem services to humans, such as improving marine water quality, providing food, spawning grounds and habitats for marine life, and absorbing carbon dioxide. Therefore, the government is seeking to preserve ZM by designating ZM-protected areas. This study examined the public willingness to pay (WTP) for the preservation of ZM using contingent valuation. The one-and-one-half-bounded model was adopted for WTP elicitation, and the single-bounded model was also applied for comparison. The spike model was employed to deal with many zero WTP responses. The household average WTP was estimated as KRW 4,087 per year, securing statistical significance. The national value was KRW 84.1 billion per year. The preservation value of ZM estimated in this study can be used as important data for economic analysis of various projects or policy implementation for its preservation.

우리나라 해양보호생물로 등록된 거머리말은 해양수질 개선, 해양생물의 먹이와 산란장, 서식지 제공, 이산화탄소 흡수 등 인간에게 중요한 생태계서비스를 제공한다. 정부는 거머리말 보호구역 지정을 통해 훼손된 서식지를 복원하여 거머리말을 보호하고자 노력하고 있다. 본 연구는 조건부 가치측정법을 적용하여 거머리말의 보전에 대한 대중의 지불의사액을 추정한다. 구체적으로 전국 1000가구를 대상으로 한 설문조사를 수행하여 자료를 수집했으며 이때 지불의사 유도방법으로는 1.5경계 모형을 채택하였다. 수집된 자료의 분석에는 영의 WTP를 다루기 위해 스파이크 모형을 적용하였고, 단일경계 모형도 추정하여 1.5경계 모형과 비교한 결과, 두 모형 사이에 큰 차이가 없는 것으로 나타났다. 거머리말의 보전에 대한 평균 지불의사액은 연간 가구당 4,087원으로 추정되었고 통계적으로 유의했다. 이 값을 전국 가구로 확대하면 국가적인 가치는 연간 841억 원에 달한다. 이 값은 거머리말의 보전에 대한 경제적 가치 또는 편익으로 해석할 수 있으며 거머리말 보전과 관련된 정책 수행에 대한 경제성 분석 시 중요한 기초자료로 활용할 수 있다.
