Abstract: Based on the world scientific center transfer theory, this study quantitatively explores the transfer characteristics of the world technological activities center countries in a long time series from the perspective of nation. The patent big data of 50 major countries/regions from 1970 to 2020 is selected as the analysis object, and on the basis of sorting out and deconstructing six analytical dimensions that reveal different aspects of the pattern evolution of world technological activities, characteristic parameters are introduced and a decision matrix is constructed to achieve the quantitative definition of the world technological activities center countries. From six analytical dimensions, the transfer characteristics of the world technological activities center countries are quantified and summarized. The results of the study show that the world technological activities center countries exhibit the following transfer characteristics during 1970-2020: (1) There exists a phenomenon of center countries transfer in the world technological activities. Since 1970, the phenomenon of center countries transfer is prevalent, no matter the traditional technology output activities, or various kinds of transnational technology exchange activities under the background of globalization, no matter the main center countries or the sub-center countries. (2) The transfer speed of the world technological activities center countries is gradually accelerating. Compared with the ultra-long technology prosperity period of over a century in ancient and the period from the mid-19th century to the early 20th century, the transfer speed of modern technology activities center countries has been significantly accelerated, and the technology prosperity period has been reduced to a time scale of several decades, and it may be further accelerated in the future. (3) The central strength of the world technological activities center countries is generally low and shows a trend of further decline. This indicates that the dominant position maintained by the current center countries in the technological activities is gradually diminishing, the concentration degree in the technological activities is gradually decreasing, which is a specific manifestation of multipolarity in the world order in the technological activities field. (4) For the present and the foreseeable future, the competition for the world technological activities center countries may mainly be fiercely contested among the United States, Japan and China. The United States is still the country that occupies the largest number and longest time of various technological activities centers, but its dominant position is diminishing. Japan is the country that occupies the second longest duration of various technological activities centers, maintaining a dominant position for a long time in a certain analytical perspective. China has recently succeeded in joining the ranks of the center countries with a significant increase in the number of technology outputs, and has enormous potential for future development.

摘要： 借鉴世界科学中心转移理论，从国别视角出发，量化探究长时间序列下世界技术活动中心国家的转移特征。研究选取1970-2020年间50个主要国家/地区的专利大数据作为分析对象，在梳理、解构出揭示世界技术活动格局演化不同侧面的六个分析维度的基础上，引入特征参数并构建判定矩阵以实现对世界技术活动中心国家的量化界定，从六个分析维度上分别量化分析世界技术活动中心国家的转移特征并进行归纳总结。研究结果显示，1970-2020年：①世界技术活动存在中心国家转移现象。②世界技术活动中心国家的转移速度正在逐步加快。③世界技术活动中心国家的中心强度普遍较低，且有进一步降低趋势。④当今及未来一段时期内，世界技术活动中心国家的角逐或主要在美国、日本和中国间激烈展开。
