交通系統扮演著連結我們的生活和經濟活動的關鍵角色，同時也帶動國家整體產業的繁榮。因此，許多先進國家積極投入研發新興智慧交通科技，如自駕車、車聯網和交通行動服務等，並透過實證和布局來推動創新服務的發展。隨著5G技術的進步，交通領域的應用也因此開始展現新的可能性。由於臺灣地狹人稠，交通壅塞問題頻繁，與經濟合作暨發展組織(OECD)的國家相比，因為交通事故而導致死亡的人數遠高於先進國家的8倍之多（公視新聞網，2023），因此改善臺灣交通系統並落實智慧交通科技帶動產業發展變成為公部門重要課題。
為應對這一課題，公部門必須尋找創新的方式來改善交通流動性，提升生活品質，並實現可持續的城市發展。然而，單仰賴公部門的力量難以獨自解決交通問題，因此與私部門的協作變得至關重要。而公私部門夥伴關係(PPPs)的協作模式因為涉及到不同組織之間的利益和目標的調和，故本研究透過個案華電聯網與交通部共同協作5G智慧交通計畫，從私部門與公部門協作的過程瞭解PPPs實務現況，作為公私夥伴關係之價值共創協作的歷程視角，並運用「公私夥伴關係」及「價值共創」的理論基礎觀點，深入瞭解因PPPs的公共性、異質性和集體行動等特性所衍生的社會困境，並進一步探討以價值共創平台為基礎的創造機制：換位思考的協商調整、建立溝通平台、資源整合、資訊透明且觸手可得，來有效解決因公私夥伴關係協作過程中所衍生的社會困境，創造PPPs共同協作的最大價值(1+1>2) 。
總體而言，本研究以私部門華電聯網與公部門交通部執行5G智慧交通計畫為研究田野，分析PPPs所衍生的三種社會困境（集體合作、資訊斷層、利益衝突），並透過價值共創的平台的運作來解決困境，並成功創造出個體價值、經濟價值與社會等價值。

The transportation system plays a critically important role in connecting lives and economies. Due to Taiwan's relatively small size, its traffic fatalities are more than eight times higher than those in OECD countries, highlighting urgent traffic challenges.

To address this issue, the public sector must seek innovative approaches to increase traffic flow, enhance quality of life, and achieve sustainable urban development. However, relying solely on the efforts of the public sector is insufficient to tackle traffic problems, making collaboration with the private sector essential.

The collaborative model of Public-Private Partnerships (PPPs) involves harmonizing the interests and goals of different organizations. This study examines the practical status of PPPs through the collaboration between HwaCom and MOTC in implementing the 5G intelligent transport technology project. It takes the perspective of cooperation between the private and public sectors, utilizing the theoretical foundation of "Public-Private Partnerships" and "Value Co-creation" to gain a comprehensive understanding of the social challenges arising from PPPs, including their public nature, heterogeneity, and collective creation.

By delving into these characteristics, the study thoroughly grasps the social dilemma brought about by PPP collaboration, and further explores value creation mechanisms based on a value co-creation platform, effectively resolving the social challenges that emerge during public-private cooperation. This successful approach generates individual value, economic value, and social value, creating the maximum value of PPP collaboration (1+1>2).
