Résumé: This study aims to examine the influence of short-form video advertisements on digital consumer behavior, with a specific focus on restaurant and food-related advertising in the Algerian context.

Résumé: The agricultural sector is considered one of the most important economic sectors that requires careful consideration for its development, given its significant importance in combating poverty, increasing income, achieving economic growth and development, as well as achieving self-sufficiency and food security. Agricultural economics is the applied field where theoretical agricultural strategies are implemented to improve production and achieve economic development.
