Research on the Design and Application of Tourism Cultural and Creative Products from the Perspective of Semiotics: Taking Caishiji as an Example

This paper explores the design methods of tourism cultural and creative products in the context of cultural and tourism economy. Guided by the theory of the semiotic trinity model, using FAHP and CRITIC models, combined with game theory, to screen and balance cultural symbols, and explore their application in the design of tourism cultural and creative products. Taking Caishiji as an example, this paper analyzes cultural symbols from four dimensions: form, pattern, color, and material, and applies them to the design practice of tourism cultural and creative products. The evaluation results indicate that this cultural symbol based design method can effectively improve design efficiency and scientificity, and the resulting tea set design scheme can also meet user needs.
