隨著資源和環境問題日益嚴峻，循環經濟的趨勢備受全球重視，被認為是實現永續發展的有效途徑。同時，企業在經營上也面臨著永續發展的挑戰，但傳統線性經營模式的企業往往難以犧牲短期利潤來追求長期環境效益，要邁向循環經濟商業模式的轉型是一大挑戰，因此需要創新的商業模式創造實質經濟效益，而循環設計能作為達成循環經濟的關鍵推手，因產品材料的循環利用程度有 80% 取決於設計階段，在產品和服務設計階段就融入資源循環利用理念，能減少原料採購和廢棄物產生，最大限度地保留和利用資源價值，為企業降低成本增加獲利來源。

本研究發現對企業而言，若實踐循環經濟能夠同時實現經濟效益，才會更有動力付諸實施，而循環設計可以通過延長產品使用壽命、提高資源利用率、產品服務化收入等多種路徑，直接或間接為企業創造新的獲利點，從而驅動循環商業模式的建立。本研究旨在探討如何利用循環設計，協助企業發展循環商業模式，並同時實現經濟與環境效益的雙贏，研究結果將提出循環設計在推動企業實踐循環商業模式的理論與實務意涵。

As resource and environmental issues become increasingly severe, the trend of the circular economy has gained global attention as an effective pathway to achieving sustainable development. Meanwhile, businesses also face challenges in pursuing sustainability in their operations. However, traditional linear business models often struggle to sacrifice short-term profits to pursue long-term environmental benefits. The transition to circular economy business models poses a major challenge, Therefore, innovative business models are needed to create substantial economic benefits. Circular design can serve as a key driver in constructing the circular economy, as 80% of the degree of material circulation depends on the design stage. Integrating the concept of resource circulation into product and service design can reduce raw material procurement and waste generation, maximizing the retention and utilization of resource value, thus reducing costs and increasing profit sources for businesses.

Circular design can create new profit points for businesses through various pathways such as extending product lifespan, increasing resource utilization, and generating revenue from product services, thereby driving the establishment of circular business models. This study aims to explore how to use circular design to develop circular business model strategies for enterprises while simultaneously achieving win-win economic and environmental benefits. The research findings will propose theoretical and practical implications of circular design in promoting the implementation of circular business models by enterprises.
