Efficiency Analysis of Public Library Services Based on Establishing Entity and Outsourcing

This study investigates the difference in service efficiency based on establishing entity and outsourcing in 847 public libraries in Korea. The public libraries were categorized into three types based on establishing entity and outsourcing, where Type 1 libraries are those established and directly managed by the Office of Education under the central government, Type 2 libraries are established and directly managed by local governments, and Type 3 libraries are established by local governments and their operations are outsourced. Each library type was analyzed and compared using data envelopment analysis (DEA), and results found that public libraries established by local governments are more efficient than those established by the central government, while outsourcing operations improved the efficiency of public libraries. Further analysis of the projection point and excess quantity of input showed that the main cause of inefficiency for Type 1 libraries is the library area, and for Types 2 and 3, the number of periodicals. This study provides guidelines for the sustainable performance of public library services based on the factors of foundation and operational patterns.
