Due to the progress in manufacturing technology, rapid changing business environment and shorter product life cycle, hi-tech industries must place greater effort in increasing their innovation technologies to meet customer demands and achieve new product development performance. This research examines Taiwanese hi-tech companies by conducting a series of innovation management activities. The influences of these activities on new product achievement is determined and analyzed. Two intermediate variables for corporate status and innovation tendency are considered in discussing the relationship between innovation management and new product development. The former belongs to the influence factor for exterior strategy, while the latter is related to interior organization. Since Taiwan hi-tech industries has gradually entered the age in which core technologies and innovative competence are starting to determine a businesss competitive advantages, this study will focus on innovation management for hi-tech industries, which is very meaningful both academically and practically. Some of the research findings are: (1) New product development performance is significant when innovation management ability is stronger (2) New product development performance is significant when innovation tendency is higher (3) Enterprise scale is not a key factor for new product development (4) New product development performance is significant when technology status is superior.
