设计科学已有几十年的研究历史，但近年其含义发生一定变化，其研究趋势也从各个层面、各个领域的设计研究发展为设计科学系统理论。本文基于Design Science杂志2015年创刊号上发表的主编文章"Design Science：Why，What and How"，分析、归纳设计科学的内涵、研究对象、研究内容、研究方向、研究方法。

The design science is not a new discipline but its contents undergo a change in the recent decade. Its focus changes from a coverage of almost all aspects relevant to the design process and the product design, to related scientific theories and methods. The frontier of the design science is to develop systematic theories and methods of design as a science. The Design Society launched a new journal named "Design Science" with an editorial article "Design Science:Why, What and How", and a discussion of 29 authors on the design science, which are reviewed in this paper.
