Cotton, as a strategic product in agriculture and industry, plays a vital role in the global and national economy and is particularly important in poverty reduction and improving access to food in rural areas. Optimal management of the cotton value chain, by increasing added value, helps improve the livelihoods of rural people. Considering the diverse applications of cotton and its role in creating sustainable employment and preventing migration, it is essential to investigate the promotional and economic factors effective on the development of its value chain. This study aimed to evaluate the impact of these factors on improving the cotton value chain in North Khorasan Province. The statistical population of this research included 3017 rural cotton farmers in North Khorasan Province. Based on Cochran's formula, a sample size of 200 people was randomly selected. The sampling method was carried out in a multi-stage manner, and data were collected through a researcher-made questionnaire after confirming face and content validity by experts in the field. To measure the reliability of the instrument and ensure the validity of the results, a pre-test was conducted, and the Cronbach's alpha coefficient for the research variables was calculated to be higher than 0.70, indicating the appropriate reliability of the measurement instrument used. The results of this research show that promotional factors have a significant relationship with the buyer selection method in the cotton value chain
