PRODUCTION‐ORIENTED INFORMATION SYSTEMS FOR AGRICULTURAL SUBSECTORS: PRINCIPLES AND TECHNIQUES
探讨了农业子部门中信息系统的设计原理与技术，指出投入产出方法可作为灵活组件满足组织的信息需求，对农业经济学者和信息系统设计者有参考价值。
The existence of problems which are peculiar to agricultural subsectors explains the presence of organisations associated with individual commodities or commodity groups. Modern developments in information systems can contribute to meeting organisations' information requirements, but it is necessary to design systems consistent with both the principles and techniques of economic analysis and the general methodology. Following the definition of a subsector, a review of the principles for information systems and the relevant economic concepts shows the formal equivalence of many basic ideas. Despite reservations which have been expressed about the current potential for quantitative techniques, an input/output approach could have an important role as a flexible component of subsector information systems.
