[Purpose/Significance] Identifying the key research directions of a technical field and mastering their layout situations of the key research directions are of great significance to fully understand the field and carry out strategic technology layout for managers and technical researchers.[Method/Process] This study proposed a content-based framework for the field's key research directions identification and layout analysis from the perspective of patent technology-effect. Firstly, through field technology decomposition and fine-grained efficacy labeling of patent data, the technology-effect matrix based on patented technology content was constructed to reveal the technical research objects and their improvement directions. Then, it proposed an identification method of the field's key research directions and constructed a layout analysis framework of the field's key research directions combined with time and space dimensions. This paper analyzed the evolution trend and maintenance of key research directions from the time dimension, and analyzed the layout of key research directions of major countries and major applicants from the spatial dimension. Finally, an empirical study was carried out in the field of the third-generation power semiconductor.[Result/Conclusion] Study on the field's key research directions and the layout from the perspective of patent technology-effect deeply reveals the field key research objects, improvement directions and technology layout strategies based on the technical content of patent documents. The empirical research shows that this analysis framework is feasible for comprehensively mastering the field's key research directions and layout situations.
