On this dissertation it is also definitely pointed that the key to research on "fantasy or trueness" virtuosity-perspective of copy-writing planning system is to solve problem about mode of thought, and presented the integrated thinking way of copy-writing planning'research of this dissertation, that is, from the point of view of copywriting integrated planning mind admitting a systemic "tripartite" viewpoint of advertising copy-writing planning system process which is thought of being "disparted" into mastermind, idea-making and expressive-technique, resolving the "fantasy or trueness -conflict" to bring to a successful conclusion of "fantasy or trueness" relation in the copywriting expression, and establishing a "dialectic virtuosity angle" of view- a "fantasy or trueness" virtuosity-perspective on copy-writing planning systemic research.

文案策划系统过程由创意策划、创意生成及创意表现三阶段组成，前两阶段属于文案策划系统研究思维方式层面的研究范围，后一阶段则属于操作方式层面的研究范围，辩证法矛盾普遍性原理决定了虚实矛盾存在于上述的一切过程及所有阶段之中，同时也存在于这个过程的结果之中。辩证法矛盾普遍性原理决定了这种特定的虚实矛盾的非对抗性质，即：虚实相生，虚以实为基础，又为实提供发展空间；虚实互为消长，统一于一体，相互作用，为广告目标及受众需要谋求虚实间最完美的比例关系匹配；这个过程中体现出&去伪存真&对&真善美&艺术境界的追求；在这个过程的结果中，则体现出文稿在视觉传达、文字的信息内涵及语义的情感诉求三个层面所追求的文稿在虚实方面的整体艺术美感。
