This dataset is sourced from the Compustat Header Historical Files (COMPHIST), covering firm-industry assignment records from 2012 to 2016. These records adopt the North American Industry Classification System (NAICS) to determine the industries that firms belong to. Each record includes GVKEY, HNAICS, and the time period of the firm's industry assignment. The dataset particularly emphasizes the temporal specificity of these assignments, with over 5,000 firm-industry assignment records per year. The core task of this dataset is firm industry assignment.
