“…The constructed model for exploring the drivers behind sustainability of HFC based on the OLS regression model was as follows: where the dependent variable represents the standardized score of sustainability for household i ( i = 1, 2, 3, …, 799); the independent variables x 1 – x 21 correspond to factors that influence sustainability of HFC, which are described as below: - Seasonal and regional variables of the season, area (rural or urban), and geographical region are set as x 1 , x 2 and x 3 , respectively. The seasonal variable, reflecting temporal variations in food consumption behaviors during different survey periods, plays a pivotal role influenced by dietary preferences, produce availability, and cultural eating habits nationwide (Li et al, 2022; Stelmach‐Mardas et al, 2016). Despite China's climatic diversity, seasonal influences on food consumption reveal consistent patterns across regions.
