本文探讨了信息系统建设中的规模经济问题。经济理论被用来确定有助于规模经济的交易属性，然后信息系统的概念被分解成可分离的组成部分。针对规模经济的一个或多个来源的可用性对每个组成部分进行分析。分析发现，每个部件至少具有实现规模经济的潜力，随着系统使用规模或能力的扩大，一些部件可能实现非常大的单位成本节约。这些调查结果对包括外包在内的信息服务组织的影响被强调，并用来自信息系统密集型行业的一致的例子加以说明。未来的研究将涉及以下方面：信息系统规模经济的实际性质；多组分系统的范围经济的存在；作为收购选择决定因素的生产成本、交易成本和收益的相对重要性；以及信息系统收购方法对公司和行业组织的影响。
This paper explores the issue of scale economies in the construction of information systems. Economic theory is used to identify transaction attributes that contribute to scale economies and the concept of an information system is then decomposed into separable components. Each component is analyzed with respect to the availability of one or more of the sources of scale economy. The analysis finds that each component possesses at least some potential for realizing scale economies and that some components may realize very large per-unit cost savings as scale of system use or capability is expanded. The implications of these findings for the organization of information services, including outsourcing, are highlighted and illustrated with consistent examples from IS-intensive industries. Future research is proposed with respect to the actual nature of IS scale economies; the presence of scope economies with respect to multicomponent systems; the relative importance of production costs, transaction costs, and benefits as determinants of acquisition choice; and the impact of IS acquisition method on the organization of firms and industries.
