Abstract: 

For considering and evaluating the economic impacts of sugar beet research on the shift of sugar supply, we need to estimate the parameter of supply shift. Having developed an appropriate methodology and using the results of breeding research collected from the main stations of sugar beet research across Iran for the period of 1982-2003, the supply shift parameter for sugar was estimated.  This parameter indicates the percentage horizontal shift of the sugar supply curve.  The percentage of sugar yield shift averaged over the period of 1983-2003 was compared to the base year (1982) for each station and the difference was considered as the performance of the station. The highest performance was seen at Mashhad station (17.21%) and the lowest at Shiraz station (-4.84%). In addition, Karaj, Hamedan and Dezful stations demonstrated positive performance whereas Miandoab and Kermanshah stations had a negative performance. The 22-year average of the parameter was 7.18% through the country. It means that Iranian sugar beet R&D policy increased the nation's welfare by more than 7%.
