卡脖子技术：概念、特征与影响因素

Purpose/Significance This study aims to investigate the concept, features, and influencing factors of the bottleneck techniques in response to the research and development demands. It employs research papers and news interviews to construct an influencing factors model that facilitates the path planning for advancements in this technique. Methods/Process The "genus-differentia" method is employed to define the bottleneck techniques and provide a comprehensive summary of its distinctive features. By considering the formation of influencing factors for the bottleneck techniques as the research question, the encoding method of grounded theory is applied to analyze textual corpus related to this technique, resulting in the development of an influencing factors model. Results/Conclusion The bottleneck technique is an industrially strategic technology at the current stage, deliberately chosen by innovative entities, characterized by originality, strategic importance, and substantial investment. The findings of grounded theory encoding categorize the influencing factors for the formation of the chokehold technique into five levels: industrial differentiation, competitive game, innovation system, production factors, and production transformation. External influencing factors include industrial differentiation as the foundational basis for competitive game. Internal influencing factors encompass the innovation system, production factors, and production transformation, with interactive relationships observed among them. The comprehensive understanding of the bottleneck technique’s concept, features, and influencing factors enables a more informed approach towards planning breakthroughs in this field. The identified influencing factors at different levels shed light on the industrial dynamics, competitive dynamics, and internal factors that contribute to the formation of the chokehold technique.
