近年來不論在學術界或實務界，都開始研究新產品開發階段的相關議題以及企業組織如何在市場與他們的顧客進行互動，然而卻很少將焦點放在新產品開發績效與市場知識導向能力對新產品研發成功的影響，因此企業應該要開始將新產品開發績效與市場知識導向能力納入整個新產品開發的控制過程中，以便降低開發的風險，同時產品也更能貼切地符合顧客需要。 為了在新產品開發階段可以將產品以更快速、低成本與高品質的方式，滿足消費者的需求，企業應該及早在新產品研發過程中兼顧新產品開發績效與市場知識導向能力，透過與客戶的互動、瞭解競爭者資訊，同時在企業內與各部門分享協調，把新產品開發的失敗率降到最低。 因此，本研究的研究焦點放在（1）新產品開發績效對新產品研發成功的影響 ; （2）市場知識導向能力對新產品研發成功的影響。本研究的研究對象為台灣數位內容產業的廠商，共寄出問卷 600份，回收 141份，經由結構方程模式來分析本研究所提出的假設支持程度，所使用的統計分析方法為 SAS應用軟體。 本研究的主要發現有： 1. 新產品開發績效對新產品研發成功是具有正向的影響。因此，企業在產品開發過程中，應該要重視開發速度、開發成本及產品品質，以提高新產品研發的成功率。 2. 市場知識導向能力對新產品研發成功是具有正向的影響。企業一旦懂得應用市場所收集到的資訊，包括顧客的資訊、競爭者的資訊，將整合的資訊傳達到企業各個部門，新產品研發的成功率則會提高。 / In recent years, many organizations in academic or practical fields start to research the related topics in development stage of new products and how the enterprises interact with their customers in the market. However, there are few focuses on the development performances of new products and the guided competences of market knowledge for successful research and development of new products. Thus, it should be necessary for enterprises to reduce the development risks of new products and simultaneously fulfill the customer requirements by involving the development performances of new products and guided competences of market knowledge into the controlled process of research and development of new products. In order to fulfill the customer requirements by faster speed, lower cost and higher quality in development stage of new products, the enterprises should pay earlier attentions on the development performances of new products and the guided competences of market knowledge in the research and development process of new products to decline the failure rate by interacting with the customer, understanding the competitor information, and simultaneously sharing the information to related departments in the enterprises. Therefore, the study will focus on (1) the effect of the development performances of new products for successful research and development of new products; (2) the effect of guided competences of market knowledge for successful research and development of new products. The research objects of the dissertation are the venders of digital content industry in Taiwan. There are 600 questionnaires mailed out and 141 questionnaires replied, and through SEM to analyze the paper hypotheses by using SAS-the statistical analysis method. The main research findings include: 1. The effect of the development performances of new products for successful research and development of new products is positive. Thus, the enterprises in the process of research and development of new products should pay more attention to the development speed, the development cost and the product quality in order to enhance the successful ratio of research and development of the new products. 2. The effect of guided competences of market knowledge for successful research and development of new products is positive. Once the enterprises understand to utilize collecting information which contains the customer information, competitor information and to transmit the integrated information to related departments, the successful ratio of research and development of the new products will be improved.
