“一带一路”背景下数字通信领域跨国专利合作特征及网络演化研究

论文以“一带一路”背景下数字通信领域跨国专利合作网络为研究对象,运用社会网络分析法,研究2000年至2019年期间中国和“一带一路”沿线地区在数字通信领域的专利合作状况,分析数字通信领域的专利合作网络在网络地位、结构洞、小世界效应和“专利权人-热点技术”二模网络联系等方面的演化特征。结果表明：中国与“一带一路”各板块专利合作地域分布不均衡性上升。网络集权程度下降,原核心国家新加坡的中心地位下降,中国、印度、俄罗斯等国中心地位逐渐上升。专利合作网络具有小世界效应,但近年来小世界效应正在减弱,影响网络稳定性。中国和新加坡在网络中的中心度和结构洞指数下降,说明中国和新加坡对网络合作资源和合作关系的影响力在减弱。中国在热点技术领域能进行专利合作广泛布局的强势企业偏少,并且专利合作在热点技术领域的宽度和深度布局有待加强。研究成果为中国未来与“一带一路”沿线地区数字通信跨国专利合作策略提供理论依据。

Research on the Characteristics of Transnational Patent Cooperation and Network Evolution in the Field of Digital Communication under the Background of

The transnational patent cooperation network in the field of digital communication under the background of the "Belt and Road" is taken as the research object, and social network analysis is used to study the status of patent cooperation of China and the areas along the "Belt and Road" in the field of digital communications from 2000 to 2019, and the evolutionary characteristics of patent cooperation networks in the field of digital communications in terms of the network status, structural holes, small world effects, the connection of the two-mode network of "patent holder-hot technology" ,etc are analyzed. The results show that the uneven geographical distribution of patent cooperation between China and the "Belt and Road" sectors has increased. The centralization degree of network is declining, and the centralization status of Singapore, the former core country, is declining, while that of China, India and Russia is gradually rising. Patent cooperation network has small world effect, but in recent years, the small world effect is weakening, affecting the stability of the network. The decrease of centrality and structure hole index of China and Singapore in the network indicates that the influence of China and Singapore on network cooperation resources and cooperative relationships is weakening. There are fewer strong enterprises in China that can carry out extensive patent cooperation in hot technology fields, and the width and depth of patent cooperation in hot technology fields need to be strengthened. A theoretical basis for China''s future strategy of digital communications transnational patent cooperation with regions along the "Belt and Road" is provided by the results.
