摘要
　　近幾年來,隨著經濟突飛猛進，及社會結構的快速變遷.新產品開發被許多企業採取用來延伸版圖及跨入新的事業領域所不可或缺的因素.在過去的研究中，社會資本及鬥士行為對於公司新產品開發績效而言，是近幾年文獻中較少探討的課題。故本研究以此為研究動機，試圖從過去學者所提出的理論整理出一些社會資本及鬥士行為影響新產品開發績效相關程度之因素及影響，配合實證的方式來驗證這些假設.並再以鬥士行為為調和作用，研究其對新產品開發績效的影響程度。

　　本研究的母體是以中華徵信所所公佈的5000大企業為主要調查對象。涵蓋了一般製造業,高科技業,及服務業,採取分層隨機抽樣，分為五層以亂數表選之，共計發放500份問卷，問卷訪問對象為各公司之新產品開發或研發部門，並以公司為單位，一家廠商寄出一份樣本.回收之有效問卷為93份，問卷之回收率為18.6%。

　　根據研究階層回歸結果發現，社會資本與鬥士行為對於新產品開發績效有正向的影響。也就是說研發團隊與組織間的互動、互信及共同遠景對新產品的開發，有相當的助益。此外，專案團隊中的英雄或鬥士，於適當的時機鼓舞團隊人員，或在遇到艱難時，仍能不畏艱難，堅持其團隊的理念，帶領著團員一直努力下去，終究可以引領其團隊走向成功之路。

Key Words: Social Capital, Champion Behavior, New Product Development.

　Recently, with the rapidly changing of economic and social structure, and the impact of internationalization and liberalization, new product development becomes the important device for enterprise to extend their business field.

Enterprise has extended it’s execution in new product development strategy, however, they should examine their direct and indirect environment, so that the enterprise can achieve the best performance.

　Although the new product development is worth discussing, little has been done in the literature in examining the relationships between among the social capital, the champion behavior, and the performance of new product development. Therefore, this study attempts to fill the gap in the literature by providing an integrative research framework through extensive literature review to identify the key determinants and to examine the relationships among these determinants and the performance of new product development.

　The population in the study originated from the Business Groups in Taiwan listed in the China Credit Information Service Incorporation. There are 93 sample firms included in the study, and multiple regression analyzes were used to analyze the data.

　The major findings of this study are that according to the results of the regression analyses, the results show supportive evidence for the direct effects of social capital, champion behavior and the moderate effects of champion behavior on the related new product development. Moreover, the results indicate that the social capital, the champion behavior and interaction effects with the related performances of new product development.
