Abstract

This Paper assesses the relative efficiency of public library services by examining the relationship between library inputs and library outputs in library systems. Using Data Envelopment Analysis, this study derives efficiency scores in the provision of library services for 21 public libraries in Seoul. The data are survey observations for 2002. We employ total holdings, total serials, and total acquisitions as inputs, and total circulations and reader visits as outputs. The result shows that the subject libraries operate at just $71\%$ efficiency, i.e., inputs could be reduced by one-three without sacrificing output if all libraries were as efficient as the benchmark 4 identified by DEA. Too many total collections are the main source of inefficiency.

본 연구는 서울 지역에 소재하고 있는 21개 공공도서관을 대상으로 DEA방법론을 사용하여 정보서비스 활동의 효율적 운영에 초점을 맞춰 상대적 효율성을 평가하였다. 정보서비스 활동의 평가를 위해 필요한 데이터는 2002년 관측치를 사용하였으며, 투입요소로는 장서수, 연속간행물수 그리고 연간증가책수가 사용되었으며, 산출물로는 총 이용책수와 이용자수가 사용되었다. 그 결과 공공도서관의 평균효율성은 $71\%$에서 결정되었으며, 이는 모든 도서관이 효율적인 도서관이 되기 위해서는 현재 수준의 산출물 생산을 기준으로 현재 투입물의 $29\%$를 감축해야 한다는 것을 의미한다. 그리고 비효율적인 도서관은 산출물의 과소생산보다는 투입물의 과다사용에 비효율의 원인이 있는 것으로 나타났으며, 특히 장서수의 운영이 가장 비효율적인 요소로 평가되었다. DEA방법론에 의한 평가 결과는 투입요소와 산출물의 수 또는 정의가 달라지면 다른 결과를 보여줄 수 있으므로 절대적인 것은 아니다.
