BIM Technology provides an important solution for the informatization of the CI (construction industry). BIM is to establish an information integrated system through certain data standards at a certain stage or in the whole process of decisionmaking, implementation, and operation of construction projects. So as to realize information sharing and information conversion and high-quality and efficient engineering construction. Engineering projects are often completed jointly by multiple project participants. Different project participants will inevitably have certain connections when applying BIM Technology in the project, thus forming a technological innovation network. Using the statistical analysis method, analyze the central data of the network, and the relationship between cross-industry cooperation and innovation performance. Based on the findings from social network analysis and statistical analysis, recommendations are proposed to optimize the network structure and boost technological innovation performance. The analysis reveals that the current network structure is relatively fragmented. To address this, new approaches for information management within the CI are suggested, focusing on modernizing and enhancing the traditional methods of information sharing and transmission.
