Since overall image and attractiveness can play a key role in developing a destination's tourism market, the current study attempts to identify the main factors influencing Iran's overall image and attractiveness from a supply-side perspective. To reduce the uncertainties in Iran's future tourism market development, we first used factor analysis to identify factors that affect Iran's tourism market. Second, we used multiple linear regressions to examine the relationships between the identified factors and Iran's overall image and attractiveness as a destination. According to the findings, political, product, and service factors significantly affect Iran's overall image and attractiveness. Third, we provided scenarios for improving Iran's overall image and attractiveness based on cross-impact balanced analysis.
