Abstract:

  For the increasing pressure on the library budgets, libraries need to prove their existing value through evaluating the monetary value. Cost-benefit analysis and economic impact analysis are the major methods for estimating the economic value, libraries usually adopt cost-benefit analysis due to the limitations of economic impact analysis. This study expounded the principles of three methods for implementing costbenefit analysis, and comparatively analysed the validity of the three methods based on several empirical applications from foreign libraries. Findings: (1)The quantitative relations among the valuation results of contingent valuation method, consumer surplus method and time value method; (2) The validity rank of contingent valuation method, consumer surplus method and time value method; (3) Which methods should be adopted by each kind of domestic libraries for implementing cost-benefit analysis.
