本研究希望了解團隊創造力對新產品開發績效（在新產品突破性與新產品目標達成度兩方面）之影響，並進一步希望了解團隊凝聚力是否也會影響新產品開發績效；此外，研究中也將討論團隊凝聚力對團隊創造力與新產品開發績效之關係的調節效果。
本研究是以臺灣高科技產業、傳統製造業的新產品開發團隊主管及其團隊成員作為主要研究對象，並以中華徵信所評比的「2008年台灣地區大型企業排名TOP5000」中前一千大為主要問卷發放對象。本研究問卷共分為A、B兩式問卷，總計發放出A卷135份與B卷675份，最後回收成套的有效問卷為26份，整體的有效回收率為19.3％，本研究主要以層級迴歸分析來進行研究假說之驗證。經由實證分析，本研究分析結果如下：
（一）新產品開發團隊創造力與新產品目標達成度呈現正向關係。亦即，當新產品開發團隊之創造力較高時，此團隊可預期能開發出較符合市場績效目標的產品。
（二）新產品開發團隊凝聚力與新產品目標達成度呈現正向關係。
本研究主要貢獻分述如下。首先，本研究為首先以團隊層級來探討成員創造力力與新產品開發績效關係之實證研究，並為少數探討在團隊情境下，成員互動良窳如何影響新產品開發績效之實證文章，研究顯示團隊創造力與團隊凝聚力皆僅對新產品市場目標達成度有所影響，並且團隊成員凝聚力高低，不會影響到成員創造力與新產品績效之關係。總結以上，本研究結果提供學術及實務界對於新產品開發團隊有更深入的瞭解，此外，並聯結了創意（creativity）與創新（innovation）兩種領域的研究，裨於後續學術之研究。

Our research want discuss the effect of team-level creativity on new product performance. Besides, we also want to find out whether group cohesiveness has effect on new product development performance. Finally, we will discuss whether NPD team cohesiveness positively moderates the positive relationship between NPD team-level creativity and NP performance.
Our research results as follow,
1. NPD team-level creativity is positively related to NP radicalness.
2. NPD team cohesiveness positively moderates the positive relationship between NPD team-level creativity and NP performance.
The contribution of our research as follow, first, our research is the first research to discuss the relationship between team-level creativity and new product development performance. Moreover, in previous studies there is few research discuss how team member interaction influence the team performance. Finally, we connect creativity and innovation two different studies to increase our understanding of these two fields.
