Abstract: Accurately identifying product innovation opportunities is essential for manufacturers to avoid blind innovation risks and continuously gain competitive advantage.Aiming at many problems in the existing research on product innovation opportunity identification,such as the difficulty of maximizing the efficiency of manufacturers′ value creation due to the single perspective,and the unclear focus of the identified innovation opportunities,a product innovation opportunity identification path based on the dual perspective of user preference and manufacturer preference was constructed.The structural topic model was used to extract the product attribute topics of user preference and manufacturer preference respectively from user online reviews and product description texts;the topic classification was performed based on the similarity between the two types of product attribute topics to obtain the innovation demand of concrete products;the innovation elements were extracted from the existing relevant patents and the product innovation opportunities were identified by relying on the multi-dimensional technology innovation map.Finally,the feasibility of the proposed path was verified by taking the elderly smart bracelet as an example to identify product innovation opportunities.The application results showed that the identification path of product innovation opportunities under the dual thresholds of user preference-manufacturer preference constructed could provide decision-making theoretical support for manufacturers to efficiently carry out product innovation activities.

Key words: product innovation opportunity identification, dual thresholds of user preference and manufacturer preference, multi-dimensional technology innovation map, structural topic model

摘要： 精准识别产品创新机会对制造商规避盲目创新风险,持续获取竞争优势至关重要。针对现有产品创新机会识别研究中因视角单一致使制造商价值创造的效率难以最大化,以及识别的创新机会聚焦度不清晰等诸多问题,基于用户偏好制造商偏好双重视阈构建了产品创新机会识别路径。首先,运用结构主题模型从用户在线评论和产品描述文本中分别提取用户偏好及制造商偏好的产品属性主题;其次,基于两类主题之间的相似度进行主题分类以获取具象产品的创新需求;再次,从现有相关专利中提取创新要素并依托多维技术创新地图识别产品创新机会;最后,以老年智能手环靶向开展产品创新机会识别为例,验证了所提路径的可行性。应用结果表明,构建的用户偏好制造商偏好双重视阈下的产品创新机会识别路径能够为制造商高效开展产品创新活动提供可资借鉴的决策理论支持。
