Spatial-temporal evolution and influencing factors of artificial intelligence innovation collaboration network in China
Using social network analysis and valued exponential random graph models, this paper analyzes the spatial-temporal patterns of China’s artificial intelligence industry’s innovation collaboration network from 2010 to 2021 and quantitatively examines its formation and evolutionary factors from 3 perspectives: network structure, multidimensional proximities and urban characteristics. The key findings are as follows: the artificial intelligence innovation collaboration network of Chinese cities exhibits a hierarchical structure, with Beijing serving as the center hub. Additionally, an urban innovation collaboration network gradually forms a “diamond” pattern comprising Beijing-Tianjin-Hebei region, the Yangtze River Delta region, the Pearl River Delta region, and Chengdu-Chongqing urban agglomeration. The network demonstrates typical heterogeneity attributes along with small-world characteristics and a “core-edge” structure. The dependence of artificial intelligence on technology and industry leads to the comprehensive impact of network self-organization, multi-dimensional proximity and urban innovation cooperation environment. The preferential attachment and the intermediary effect significantly promote network development, while the characteristics of technological proximity of innovation cooperation change from complementary innovation to the coexistence of complementary and collaborative innovation. Geographical distance and inter-provincial barriers no longer impede innovation cooperation. The urban innovation environment foster the breadth and depth of innovation collaboration but the disparities in development levels between cities hinder cooperation establishment.
