الملخص EN

The research aimed at estimating of the demand meat and fish in the kingdom of Saudi Arabia on the basis of yearly data between the period of 1980-1998.

the demand of meat and fish in the kingdom was estimated depending on the linear approximate almost ideal demand system (la/aids) using three-stage least squares method to estimate the aids model.

the estimated coefficients were used to estimate the compensated and uncompensated price elasticities and expenditure elasticity.

fish was aggregated in three groups; pelagic fish, demersal fish and fresh water fish.

similarly, meat was aggregate in four groups; mutton, camel, imported beef meat, and poultry.

the study achieves some results; as follows : 1) the price variable has significant effect on consuming the four kinds of meat.

while, the expenditure variable has significant effect on all commodities except sheep meat.

2) the consuming of pelagic fish and demersal fish is sensitive to changes in the prices of mutton and imported beef meat.

whereas, the consuming of mutton is sensitive to changes in the own price and the prices of imported beef meat and poultry while the consumption of camel meat is affected by the price of camel meat and price of imported beef meat.

therewithal, the consumption of imported beef meat is sensitive to changes in its price and the price of poultry.

3) the uncompensated own price elasticities have negative sign for all commodities included in the study and they are significant at level of 0.5 and greater than one (as absolute value), for all kinds of fish, which means that the consumption of fish is sensitive for changes in fish price.

on the other hand, the own price elasticities of meat and poultry are less than one.

this means the consumption of meat and poultry is not sensitive to changes in own prices.

remarkably, regarding the own price changes, camel meat is the most inelastic commodity4) the expenditure elasticities of all commodities included in the study are positive and significant at 0.05% significant level, except demersal fish and fresh water fish.

in addition, expenditure elasticities of fish are greater than one meaning they are luxury commodities, while the expenditure elasticities of meat and poultry are inelastic (they are less than one) which means that they are necessity in the kingdom.

5) consumption of mutton, camel, and poultry is more sensitive to changes in consumer's income than changes in prices.

while the consumption of imported beef meat is affected by the price changes more than changes in consumer's income.

6) there is a substitute relation among fish products but they are inelastic and not significant.

meaning, consuming one group of fish is not effected by price changes occur in other groups.

generally, the consumption of meat in the kingdom is not elastic to changes in fish prices.

additionally, it shows that the fish consumption is effected by meat prices.

the results showed that there is a substitute relation among mutton and the rest of commodities within the study, and the same saying goes for poultry.

7) price of imported beef meat has no impact on the per capita consumption of mutton, camel, and poultry.

on the other side, the prices of mutton, camel, and poultry has impact on per capita consumption of imported beef consumption.

this can be explained by the consumer's preference.

the consumer prefers the mutton, camel, and poultry meat than the imported beef meat.
