全球環境問題長期都伴隨著人類社會經濟活動之活耀，而呈現不同程度和類型的影響，我國經濟自從發展至工業型態開始，隨著經濟成長同時環境也逐漸污染，舉凡空氣、水、廢棄物等污染議題已不間斷在國際間發酵，因此我國也跟隨國際腳步逐漸重視國內環保議題。同時我國民眾知識與環保意識的抬升，對於民生用水的要求也越來越高，為解決民眾需求，政府單位也開始重視經濟發展帶來的環境污染議題。
本研究以國立成功大學環境工程學系為例，其為我國第一所為給水、供水而設立之學術單位，以培養優秀環工人士而成立，並協助解決高雄地區自來水質不佳之社會議題且成功建立起我國第一座高級淨水處理廠，故選為本研究對象。本研究透過質性研究之單一個案研究法，結合價值共創、價值主張、服務主導邏輯與服務生態系統之理論來深入探討國立成功大學環境工程學系如何與利害關係人互動，利害關係人又是如何受到價值主張的吸引並進行資源之整合與交換，進而形成穩定之服務生態系統。
以服務主導邏輯對國立成功大學環境工程學系的分析結果發現，首先欲獲得競爭優勢必須先發展並強化自身的優勢，其中成大環工最大的策略利益為其操作性資源，並瞭解如何善用操作性資源與被操作性資源之整合與交換。此外，欲形成服務生態系統必須先有明確的價值主張，同時不同行動者皆須認同此價值主張才得以被吸引加入並進行資源整合與服務的交換，並且將無形之知識轉變為有形之設備與流程，各行動者間從溝通協調中透過共同語言此工具來進行制度調適，其中因各行動者間凝聚出信賴感與共識，更能形成共享的制度邏輯，進而形成穩定之服務生態系統，最終價值共創並無法靠單一行動者來完成，而是需要不同行動者的加入進行更多元之服務交換，從而提升服務生態系統的總價值。

In this study that focus the Department of Environmental Engineering, National Cheng Kung University. It has collaborated to establish the first advance wastewater treatment plant in Kaohsiung with Taiwan Water Corporation and solved the poor water in Taiwan. The purpose of this research is to explore value co-creation in the Department of Environmental Engineering, NCKU based on Service-dominant (S-D) logic and revealing the value proposition how to attract stakeholders, resource exchanging to further shape a service ecosystem by applying the single case study method of qualitative research.

By analyzing the research results, it was found the biggest strategic interest is its operational resources, and understand how to integration and exchange of operational resources and operand resources. In addition, in order to shape a service ecosystem, there must be a clear value proposition, and different actors must agree it. In the shaping of process, the actors adjusted the system through communication and coordination with the common language. Besides, because of the trust and consensus among the actors, they can form a shared institutional logic and shaped a stable service ecosystem.
