Analysis of the dual network relationship and its evolutionarycharacteristics of global textile new material technology cooperationR&D in the 21st century

Vigorously developing new materials technology is of great significance to improving the high-tech level of the textile industry, enhancing the transformation and upgrading of the textile industry, promoting the sustainable development of the industry and enhancing the comprehensive national strength. In this paper, the data of 6982 invention patents created by global textile new material technology cooperation are chosen as the research object, and the patent technology network analysis method is used to examine the dual network relationship and its evolution features. The results suggest that the core subjects represented by multinational corporations, well-known universities and scientific research institutes integrate resources to conduct technology cooperation research, and the cooperation network’s innovation activities in this field tend to be stable, but there is no relatively stable collaborative relationship between innovation organizations. Furthermore, technology nodes, technology subgroups, spillover effects between technologies, diffusion and fusion, and technology correlation strength have greatly improved. At the same time, reasonable division of labor and coordination of the collaborative activities among nodes in the core, middle, and edge layers of the network are crucial, and the division of labor and cooperation within the network are of great significance for improving collaborative innovation efficiency. This study is useful to determine the innovation subjects, network structure and technological evolution of global textile new material technology cooperation research and development, but there is no analysis of the relationship between organizational cooperation network and technological network and its evolution characteristics in this field. As a result, this article tries to supplement existing research in terms of both research object and research content, to fill the gaps in the existing research.
