英文摘要：

In the age of information, sustainable competitive advantage for an enterprise can be maintained through infonnatization, yet informatization must be completed step by step because of such problems as its complexity, extensibility, and its inherent interconnectivity. Specific challenges that enterprises face in informatization include： （ 1 ） how to work out the priorities and the timetable; and （2） how to better understand the rdationship between informatization and maintenance of sustainable competitive advantage. This paper argues that an analytical framework for enterprise informatization strategy on the basis of dependency on information is a useful tool and model for informatization planning and is likely to contribute to better strategic planning for informatization.
