面向美国出口管制的关键核心技术识别与特征测度OA

[Purpose]The prerequisite for achieving the breakthrough of key core technologies in China is the identification of key core technologies.From the perspective of U.S.export control on China,this paper researches on the key core technologies of our country's constrained enterprises,to provide reference for our country to win the battle of key core technologies.[Method]The paper uses Word2vec model to calculate the similarity between the description text of the list and the patent text of China's controlled enterprises,based on the list of key emerging technologies,the business control list and the entity list of the United States,so as to identify the key core technologies of China's AI.The paper uses XGBoost algorithm and SHAP interpretation method to analyze the important characteristics of the key core technologies of AI in China.[Result/Conclusion]The paper identifies6882 AI key core technologies from 50445 patents applied by 228 Chinese controlled enterprises between 2018 to 2024.Technology influence,protection,scientific basis,market prospect and technology integration are the high differentiation characteristics of the key core technologies of AI in China.
