近年来,我国对公共图书馆事业的投入不断增大,政府和社会大众越来越关注图书馆的价值,而这关键就是要测算图书馆产生的效益。然而,很多人并不认同图书馆能够产生效益这一观点,本文通过系列研究证明图书馆的效益是存在的且是可以测算的。这一结论无论从政府公共支出角度还是从公共图书馆发展的内在需求来考虑,都是十分有意义的。 In recent years, China’s investment in the public library has been steadily increasing. The government and the general public are paying more and more attention to the value of the library, and the key is to measure the benefits generated by the library. However, many people do not agree with the library can produce benefits from this view through a series of studies to prove that the effectiveness of the library is there and can be measured. This conclusion is of great significance both in terms of the public expenditure of the government and from the inherent needs of the development of public libraries.
