This study takes A-share listed companies in China from 2014 to 2024 as the initial research sample and processes the original data as follows: (1) excluding samples that were classified as ST, *ST, or PT during the year; (2) excluding samples from the financial industry; (3) excluding samples with insolvency or missing key variables; (4) winsorizing all continuous variables at the 1% level at both tails, resulting in a final sample of 14,904 observations.

Strategic alliance data were manually collected from the texts of listed company announcements in the Wind database; green patent data were obtained from the CNRDS database; and the remaining financial data were sourced from the CSMAR database.
