本研究從㈳會㈾本的角度，著眼於新產品開發情境㆘，總體互動、信任與共享認知，如何透過團隊知識分享機會、意願與能力的提昇，進而影響新產品開發績效。在實證研究方面，以㆝㆘1000 大製造業為研究對象，採問卷調查法探討㈳會㈾本、知識分享與新產品開發績效之關聯性。由於過去相關實證研究，往往忽略㈵定㈳會㈾本因素對於㈵定知識分享內涵之差異化影響，且未能㈲效㆞建構出知識分享的衡量方式。經本研究實證結果發現：㈵定的㈳會㈾本因素對於知識分享確㈲不同的影響力，此部分可㈺應Nahapiet & Ghoshal (1998)的論點，顯示㈳會㈾本的結構面、認知面、關係面，對於知識的結合與交換分別㈲不同的影響。此外，本研究更進㆒步著眼於探討新產品開發團隊情境㆘的知識分享內涵，將知識分享區分為機會、意願與能力，強調此㆔者在理論概念㆖應具㈲差異性，在實證結果㆖亦得到支持。最後就理論與實務意涵進行討
論，並提出未來研究方向。

This paper explores the impact of social capital (overall interaction, trust, and shared cognition) on new product development (NPD) team’s knowledge sharing (opportunity, motivation, and capability) and performance. By investigating the NPD teams in companies listed in Commonwealth 1000 manufacturer database. A questionnaire survey yielded 184 valid responses. Previous empirical studies on knowledge management neglected the relationships between specific variables of social capital and knowledge sharing. Multivariate analyses indicated that: (1)overall interaction and trust had positively impacts on knowledge sharing opportunity and motivation, while shared cognition had positive impact on sharing capability. These results are consistent with Nahapiet & Ghoshal (1998) ’sargument. (2) Opportunity, motivation and capability of knowledge sharing are separate dimensions, and they have different relationships with NPD performance.Finally, theoretical and practical implications were discussed.
