Artificial intelligence (AI) technology is a new focus for international competition, with countries around the world accelerating major outlay to enhance their innovation competitiveness. Identifying the global situation of AI technology is a strategic issue for enterprises and countries. Considering current deficiencies in research directed towards this, the content for analysing technological competition situations should be determined from the two most relevant levels of: 1) technology's dimension; 2) research and development (R&D) actors' dimension, with time (T), market (M), technology (T) and subject (S) as its four elements. This paper, therefore, proposes an analytical framework of technological competition situation, based on the four dimensions of TMTS. AI technology is taken as an example to verify the feasibility and effectiveness of the analytical framework. This paper will contribute to our understanding of the global competitive situation of AI technology, and will be of interest to AI technology's R&D experts.

确定人工智能技术的技术竞争状况-专利态势分析

人工智能（AI）技术是国际竞争的新焦点，世界各地的国家都在加大投入以提高其创新竞争力。确定AI技术的全球形势对于企业和国家来说都是一个战略问题。考虑到当前针对此问题的研究不足，应从两个最相关的层面确定分析技术竞争状况的内容：1）技术的规模；2）研究与开发（R＆D）参与者的维度，以时间（T），市场（M），技术（T）和主题（S）为四个要素。因此，本文基于TMTS的四个维度，提出了技术竞争状况的分析框架。以人工智能技术为例，验证了该分析框架的可行性和有效性。本文将有助于我们了解AI技术的全球竞争状况，并使AI技术的研发专家感兴趣。
