The work aims to explore innovative methods for Sichuan Opera cultural and creative design based on the cultural hierarchy theory, and expand the ideas and innovative methods of Sichuan Opera cultural and creative design. Based on the theory of cultural hierarchy, by summarizing and sorting out the cultural resources of Sichuan Opera, the cultural resources of Sichuan Opera were divided into three categories:material resources, behavioral resources, and spiritual resources. The cultural genes contained in the three types of resources were clarified, and a Sichuan Opera cultural and creative design model framework was constructed through design transformation. Based on the characteristics and application methods of different cultural resources, innovative design methods for three types of resources were explored, and relevant cultural and creative product cases were listed. Based on the different characteristics of three types of Sichuan opera cultural resources, innovative methods could be derived, including in-depth, intuitive, and derivative innovation methods for explicit elements under material resource characteristics, technological, practical, and environmental innovation methods for usage under behavioral resource characteristics, and innovative methods for aesthetic, symbolic, and educational functions of emotional experience under spiritual resource characteristics. The application of these innovative methods can enable Sichuan Opera cultural and creative product design to have diverse forms of innovation, diverse usage methods, and deep emotional experiences.
