从信息资源建设规模控制角度对数字图书馆边界的波动、均衡、扩张、优化问题进行探讨,认为信息资源建设规模限定是导致数字图书馆边界存在的根本原因。同时,数字图书馆边界的波动源自其自身生存与发展的内在要求,多方博弈、有限竞争以及资源专用性和官僚性扭曲陷阱等因素影响着数字图书馆外部边界的扩大或缩小。基于信息资源建设效率考虑的数字图书馆可扩大或抑制信息资源建设规模,实现信息资源合理配置和提高信息资源利用效率。
From the view of scale control of information resources construction, this paper discusses the fluctuation, equilibrium, expansion and optimization of digital library boundaries. It is concluded that the limited size of information resources construction is the fundamental reason leading to the existence of digital library boundaries. At the same time, the fluctuation of digital library boundary comes from the internal requirements of its own survival and development. Factors such as multi-party game, limited competition, resource-specific and bureaucratic distortion trap affect the expansion or contraction of the digital library’s external boundaries. Digital libraries based on the efficiency of information resources construction can expand or restrain the scale of information resources construction, realize the rational allocation of information resources and improve the utilization efficiency of information resources.
