企業透過供應商參與新產品發展活動進而創造更佳的新產品和服務價值為近年來在管理文獻上的一個重要觀念。在和上游供應商合作過程中，了解不同類型供應商參與行為成為有效管理並提升廠商新產品開發效能之關鍵因素。然而，目前大多文獻將供 應商參與行為視為單一構面，甚少文獻將其進行更細緻的構面分類，並探討其背後不同的績效意涵，這造成了在供應商合作管理上的知識缺口。有鑑於此，本研究透過大量文獻回顧，發展一個觀念性架構說明供應商參與新產品發展的兩大構面(供應商資訊分享和供應商共同開發)之本質差異，並且進一步解釋兩者對於不同 新產品績效上的影響。更確切來說，本研究發現企業於新產品發展過程中運用「供應商資訊分享」及「供應商共同開發」可有效同時提升「產品創新」和「產品品質」之績效表現。另一方面，「供應商資訊分享」及「供應商共同開發」在對於企業之「產品發展速度」則無顯著影響效果。本研究也透過上述之發現對於供應商合作管理之理論和管理實務觀念上做出貢獻。
The benefits of supplier involvement in new product development (NPD) performance outcomes are well recognized. It is important for firms to understand the performance implications of different dimensions of supplier involvement in NPD. Yet, the current literature tends to conceptualize supplier involvement in NPD as an unidimensional construct, resulting in the knowledge gap in terms of supplier collaborative management.
Therefore, by using comprehensive literature review, this study developed conceptual architecture includes two major aspects, supplier involvement in information sharing and supplier involvement in co-development, associated with characteristic difference. Furthermore in analysis of performance impact by the two aspects. Importantly,this study articulates, the NPD of enterprises, using supplier involvement in information sharing and supplier involvement in co-development, can improve both product innovation and product quality. In the other hand, supplier involvement in information sharing and supplier involvement in co-development do not have a significant impact on product time to market. The notions of this research offer managerial implications to supplier management and collaborating for performance of NPD.
