近年來供應商涉入新產品開發的議題，廣受實務界與學術界的重視。而且有愈來愈多的研究認為讓供應商早期涉入顧客新產品開發專案中有助於新產品開發專案績效的提升，但是只要讓供應商涉入新產品開發中便可達成提升新產品開發績效與加速產品開發速度的目的嗎? 由日本汽車業供應商管理的實務來看，日本式的新產品開發過程與會依照供應商不同的角色來區分其涉入新產品開發專案的程度，而並非如西方經理人所理解的只要讓所有的供應商全部涉入到新產品開發過程中即可提升新產品開發專案的績效，應該要區分供應商涉入角色才能達成提升新產品開發發案績效的目的。
但到底是什麼因素會使得供應商會在新產品開發專案中扮演不同的角色呢? 這些影響因素是如何影響供應商涉入角色? 供應商涉入角色與新產品開發專案績效有無顯著關係? 此乃是本研究的主要的研究問題。於是本研究針對影響供應商涉入角色與新產品開發專案績效的因素進行文獻探討，確認出會影響供應商涉入角色與新產品開發專案績效的因素，包括下列變數：供應商技術能力、供應商承諾、及顧客本身技術創新。於是，本研究針對影響供應商涉入角色因素、供應商涉入角色與新產品開發專案績效進行實證研究。
本研究針對國內高科技製造商作為研究對象，共發出問卷300份，回收66份，整體回卷率為22%。將回收之廠商資料進行路徑分析、集群分析、與差異性檢定。得到以下之研究結果：
(1)顧客權力優勢愈高，會使供應商承諾愈低。
(2)供應商承諾愈高時，會使供應商涉入角色愈偏向合夥者。
(3)供應商的技術能力愈高時，會使得供應商涉入角色愈向合夥者。
(4)供應商涉入角色愈偏向合夥者時，將會提高新產品開發專案的績效。
(5)顧客本身技術創新程度愈高時，將會提高新產品開發專案的績效。
本研究將針對研究結果提出對實務界與學術界的貢獻，並提出對未來有興趣從事相關領域研究之學者一些研究上的建議。
