簡介目錄

預計 2025 年全球翻新和行動電話市場價值將達到 597.7 億美元,到 2032 年將達到 1,121.1 億美元,預測期內(2025-2032 年)的複合年成長率為 9.4%。

翻新/二手行動電話是透過維修、更換零件和品質檢查恢復正常功能的二手設備。這個市場受到對經濟實惠的智慧型手機替代品日益成長的需求、對電子廢棄物日益成長的擔憂以及循環經濟模式日益普及的推動。這些設備迎合了注重成本的消費者、希望大量購買的企業以及有環保意識的買家的需求。該市場涵蓋了蘋果、三星和小米等主要智慧型手機品牌的各種設備,透過線上平台、零售店和認證翻新項目銷售。

全球翻新和二手行動電話市場受到幾個關鍵因素的推動,其中包括新智慧型手機價格上漲,導致許多消費者尋找經濟實惠的替代品。電子商務和線上市場的興起增加了經過認證的翻新設備的可用性,進一步促進了銷售。此外,政府推動永續消費和減少電子廢棄物的措施也鼓勵了智慧型手機的轉售和回收。帶有保固的翻新設備的出現增強了消費者信心並促進了市場採用。此外,翻新過程中的技術進步,例如基於人工智慧的品質檢查和先進的維修技術,使二手行動電話更具吸引力。

儘管翻新和行動電話市場成長前景看好,但它也面臨著品質不穩定、保固範圍有限以及假冒和篡改風險等挑戰。與新智慧型手機相比,消費者對該設備的使用壽命和性能的擔憂是採用該設備的障礙。此外,一些智慧型手機製造商實施了限制性維修和零件供應政策,這使得第三方翻新商難以維持高品質標準。此外,二手設備沒有標準化的分級系統,這給買家帶來了困惑。

隨著新興經濟體中數位包容性措施的不斷加強,價格實惠的智慧型手機使得網路存取更加廣泛,翻新和行動電話市場提供了巨大的成長機會。製造商、通訊業者和維護提供者之間的策略夥伴關係可以提高供應鏈效率並擴大市場範圍。知名品牌和零售商推出的認證翻新計畫可望增強消費者信任和市場信心。此外,人工智慧診斷和區塊鏈追蹤解決方案的整合提高了透明度,確保買家收到具有經過驗證歷史的高品質翻新產品。

本報告研究了全球翻新和行動電話市場,提供了按類型、價格分佈範圍、銷售管道和地區分類的趨勢見解,以及參與市場的公司概況。
