The study focus on testing the determinants of competitive advantage of dates marketing from Saudi Arabia
through multi- regression model based on Porter's diamond, which is determined the factor that affecting on
competitiveness of nations in international marketing, such as factor conditions, demand conditions, related and
supporting industries, and company strategy; structure; and rivalry. Our study selected the most competitive
countries for Saudi Arabia in marketing dates in its markets (like Egypt, Iraq, and Tunisia). The results of study
showed that the four determinants are significant and R square is high more than 95% in all equations this is
agree with our assumptions, but the signs parameters of these determinants are different from our expectations
specially with the quantity of production in Saudi Arabia which appear negative with the value of export of dates
from KSA, that is because the consumption of dates in domestic market is high and it absorbs the high quality
kind of dates, which is needed for external market. We tested also the same determinants for the competitive
countries (Egypt, Iraq, and Tunisia); we found the same results, except Egypt, which have huge domestic
demand that is effect on demand conditions in this country. Our study suggested more studies are needed for
related and supporting industries of dates with this crop, to save data base in this field, and give more attention
for quality of dates, packaging and prices for Saudi exporting of dates.
