在视觉营销中，空间常被转化为人们可探索的空间视觉线索，进而影响消费者的感知、态度及行为。基于LDA主题模型及文献回顾，本研究首先将空间分为空间距离、空间密度、空白空间以及空间位置四个维度，随后分别阐述四种空间维度对消费者行为的影响。同时，基于情绪与认知两个层面，探讨空间效应背后的四种机制。最后，本研究提出相关未来研究方向。

Space is widely used in visual marketing practice, and they are generally converted to spatial visual cues that people can explore, thus influencing consumer perception and behavior. Adopting methodologies of both Latent Dirichlet Allocation (LDA) topic modeling and manual coding based on existing literature, this paper systematically discusses four core contents of space: spatial distance, spatial density, white space, and spatial location. It then discusses how each of these dimensions impacts consumer behavior. Additionally, the mechanisms of the impact of space on consumer behavior are explored based on the emotional and cognitive decision-making process. Finally, the paper proposes future research directions for space.
