Idea Sets
提出'创意集合'作为分析创业机会识别的新单元，定义其维度并开发问卷工具，帮助克服样本选择偏差。
Idea sets—the complete stock of entrepreneurial ideas an individual has accessible within his or her memory at any given time—are proposed as a new unit of analysis through which the antecedents, processes, and outcomes of entrepreneurial opportunity recognition may be more fully understood. A number of dimensions are identified along which one person’s idea set may be compared with that of another person. These comprise the novelty, volume, content, stage of development, strategic value logic, and composite knowledge configuration of ideas within the idea set. The idea set construct and the methods advocated for its empirical operationalization provide a differentiated, comprehensive approach to investigating entrepreneurial opportunities. They also help to overcome sample selection and survival biases characterizing empirical research in this domain. A questionnaire-based idea set instrument, designed and tested in the corporate context, demonstrates good evidence of content, convergent and divergent validities.
