"Research on the Impact of Large Model Technology Diffusion on the Innovation Ecology of the Industrial Chain" - Dataset

The selection during the sample period is based on the following considerations: in 2020, the 100 billion parameter level model represented by GPT-3 was launched, ushering in a new stage of general artificial intelligence, and Chinese enterprises began to systematically explore the industrialization path of large-scale model technology; Using 2024 as the endpoint of the sample not only ensures the timeliness and completeness of the data, but also fully captures the complete evolution process of large-scale model technology from initial exploration to large-scale application. Data collection involves multiple dimensions and sources.

The financial information and corporate governance data of listed companies mainly come from the CSMAR database, China Research Data Service Platform (CNRDS), and Wind financial terminal. The relevant data of the application of big model technology is manually collected through multiple channels, including systematically sorting out the relevant disclosure information in the annual reports of listed companies, tracking the technical white papers released by enterprises, and monitoring the participation records of mainstream open source communities.
