This study is about the relations between ¡§technology innovation kinds¡¨ and ¡§knowledge management kinds¡¨, and takes ¡§the performance of new product development¡¨ for measuring it. The concept of technology innovation kinds is by Henderson and Clark(1990), which depends on the ¡§Component knowledge¡¨ and ¡§Architectural knowledge¡¨ enhanced or destroyed, gets 4 kinds: incremental¡BArchitectural¡BModular¡Band Radical. On the other hand, concept of knowledge management kinds is developed by this study, which depends on ¡§the environment for sharing knowledge¡¨ formal or informal; ¡§the source of knowledge¡¨ from inside the company or outside, gets 4 kinds: database¡Bspace for communicate¡Bnetwork¡Band real time communicate. Besides 4 cases for explaining the relations, this study uses statistic for studying manufacturing industry, and finds: 1. Every of the technology innovation kinds prefers its own knowledge management kinds. Like: ¡¨ incremental¡¨ prefers ¡§ database¡¨¡B¡¨ Architectural¡¨ prefers ¡§space for communicate¡¨¡B¡¨Modular¡¨ prefers ¡§network¡¨¡Band ¡§Radical¡¨ prefers ¡§real time communicate¡¨. 2. The technology innovation kinds correspond to its own knowledge management kinds, and the performance of new product development will be higher. 3. The high-tech industry¡¦s new product development performance is higher than the traditional industry¡¦s as their innovation kinds correspond to its own knowledge management kinds. 4. The smaller company¡¦s new product development performance is higher than the larger one as their technology innovation kinds correspond to its own knowledge management kinds.
