Abstract:For the evaluation of major scientific and technological achievements, in order to avoid the problems caused by traditional evaluation methods such as valuing quantity over quality, valuing form over content, and valuing short-term over long-term, and to break through the original path dependence, this study adopts an exploratory case analysis method. Based on grounded theory, typical cases are selected through three categories of major scientific and technological achievements research and development processes: basic research, applied research, technology development and industrialization achievements. Open coding, spindle encoding and selective encoding are used to select typical cases, exploring the construction of a theoretical model for the traceability path of the R D process of major scientific and technological achievements, and reasonably evaluating the contribution of the R D process of major scientific and technological achievements. This study reveals that the retrospective and phased evaluation of the R D process is an inevitable requirement for the transformation of major scientific and technological achievements. It clarifies the direction and mechanism characteristics of the retrospective path for the transformation of major scientific and technological achievements, promotes institutional design and policy innovation, and stimulates the vitality of scientific and technological innovation.
