摘要

This paper employs data envelopment analysis (DEA) of US EPA Community WaterrnSystem Survey data (EPA, 2002) to compare the relative efficiencies of facility ownership type andrnnature of water source for potable water utilities. Three ownership types (private for-profit, privaternnot-for-profit, and public) and two types of supply sources (ground and surface water sources) arerncompared. Statistically significant results indicating the efficiency advantage of certain utility typesrndepending on measurement variable selection were found, and clear trends towards certain utilityrntypes were identified, notwithstanding the variable selections used for measurement. The findingsrnindicate that public utilities are most efficient overall, followed by private not-for-profit utilities,rnwith private for profit utilities being least efficient. Except for a few cases of very large supplyrndemands, utilities employing ground water sources were generally more efficient than those usingrnsurface water sources.rnA brief investigation into the marginal return on information obtained from using additionalrnmeasurement variables to measure utility performance is also presented. It is demonstrated thatrnadditional ranking information can be obtained by using more discrete measurement variables, butrnthat there are diminishing marginal returns. This efficiency evaluation of public water utilitiesrnshould prove useful as a tool for guiding ownership policy and water source development.
