Abstract

This study was conducted with the purpose of focusing on local water supply services, identifying equity and influencing factors, and analyzing the results. Using the Coulter model for 152 local governments across the country, equity was measured for six variables, including average unit price, rates of recovering costs from water price, revenue water ratio, water supply rate, number of employees, and customer satisfaction. Among them, the level of inequality in the average unit price was the highest. As a result of trend analysis, the degree of equity of most variables decreased. In addition, through Tobit analysis, factors influencing equity such as financial independence, local tax burden, and administrative district level were confirmed. In order to provide equitable water supply services, institutional changes such as rate increases are needed. And the government and local governments must pursue various water supply plans.

본 연구는 지구 온난화와 기상이변으로 물의 중요성이 커지는 현실에서 지방상수도 서비스에 주목하고 형평성과 영향요인을 확인하여 결과를 분석하고자 하는 목적으로 수행되었다. 전국 152개 지자체를 대상으로 Coulter 모형을 사용하여 평균단가, 요금현실화율, 유수율, 상수도 보급률, 직원 수, 고객만족도 등 6개의 변수에 대해 형평성을 측정한 결과 평균단가의 형평성 수준이 가장 낮았으며 추이 분석 결과 대부분 변수의 형평성이 하락하였다. 또한 토빗회귀분석을 통해 형평성 영향요인을 비형평성 계수에 미치는 영향을 기준으로 확인한 결과, 재정자립도는 모든 변수에서 정(+)의 영향을, 1인당 지방세 부담액은 부(-)의 영향을, 시/군 여부는 고객만족도를 제외한 5가지 계수에 부(-)의 영향을 끼치는 것으로 나타났다. 한편 상수도 서비스의 형평적 제공을 위해서는 시설개선을 위한 요금 인상 등의 제도 변화가 필요하고, 기후 위기 상황에서 정부와 지자체는 지방상수도의 형평적 공급을 위하여 공급 다변화 방안을 추진해야 함을 정책적 함의로 제시하였다.
