科技帶來生活上的便捷與好處，使得組織跨領域發展創新。進行新產品創新專案的同時，團隊之市場行銷人員和研發人員需要尋求外部知識，以達成產品創新績效和專案效率，由於外部知識困難且取得不易，使得組織缺乏該新產品創新知識，若在知識不足的情況下進行創新，產品創新則毫無新意，因此藉由團隊多樣性填補缺口，並加強組織成員之間的信任、關係和認知，改善產品創新績效和專案效率。
過去研究大多將知識距離以知識多樣性的角度去衡量，且將團隊多樣性和社會資本大多被視為討論對象或中介變數，作為研究架構。因此，本文根據Ozer andZhang (2018)，將知識距離分為市場距離和技術距離，以探討對新產品開發的影響，以及被團隊多樣性和社會資本調節後的影響。

Technology brings convenience and benefits to life, enabling organizations to develop innovation across fields. Conducting the new product innovation project, the team's marketing and R&D need to seek external knowledge to achieve product innovation performance and project efficiency. However, it is difficult for team members to obtaining external knowledge and the situations would make the organization lack of the knowledge for new product innovation, which has resulted in the poor innovation performance.
Based on this gap, past studies showed the results that could be solved by team diversity, and strengthening the willingness by trust, relationships and cognitive views
among members of the organization to achieve the goals. Both of them can positively improve the performance of product innovation and project efficiency.
Past research models mostly discussed the knowledge distance from the perspective of knowledge diversity, also regarded team diversity and social capital as
discussion objects or mediation variables.
According to Ozer and Zhang (2018), the knowledge distance was divided into market distance and technical distance. Therefore, this study used both of them as the
research role to explore the effect of new product development performance, and discussed the effect of which was adjusted by team diversity and social capital.
