هدفَ البحث إلى اختيار نموذج قياسي مناسب للإنفاق الاستهلاكي على لحـم الغـنم المحلـي عنـد المستويين (الأسرة و الفرد) في محافظتي دمشق و ريف دمشق بالاعتماد على بيانات قطاع عرضي للعـام 2009 .بينت النتائج أن أفضل نموذج قياسي للتعبير عن علاقة الإنفاق الكلي و الإنفاق على لحم الغنم عند مستوى الأسرة و الفرد هو الصيغة اللوغارثمية المعكوسة. إذْ بلغت قيمة معامـل التحديـد ( R2 ) 0.203 و 37.0 عند كلا المستويين الأسري و الفردي على التوالي. و بلغت المرونة الإنفاقية الاستهلاكية للأسـرة عند المستوى المتوسط للإنفاق نحو 867.0 – و تبين أن لحوم الأغنام المحلية تعد سلعة كمالية في حالة انخفاض إنفاق الأسرة الكلي عن 18001 ل.س/شهر، إذ تزيد المرونة الإنفاقية على الواحـد الـصحيح لتقدر بنحو -074.1 عند فئة الإنفاق الأسري التي تراوح بين 16001- 18000 ل.س شهرياً.
This study aimed to choose a suitable standard model of consumer expenditures on local sheep meat at two levels, family and capita by using cross-section data for the year 2009. Results showed that the Log-Inverse (LI) functional was the best model to express the relationship between total expenditure and spending on sheep meat expenditure at family and capita levels and the values of coefficient of determination (R2) were 0.203 and 0.37 at family and capita levels respectively with expenditure elasticity was 0.867 at family average expenditure level. This might reflect the fact that the sheep meat is considered a luxury commodity in case of decreasing family average expenditure below 18001 SP per month.

The cherry fruit is classified to be after the apple fruit according to its
economic importance and the cherry tree is firstly considered economically
important due to its continuous and plentiful bearing if it’s provided with all
requirements and
techniques for the suitable agriculture and its needs from
irritation and fertilizer are medium. The aim of the research was to study the
costs of production cherry with a comparison between some economic
indicators for each of the cherry rainfed and irrigated cherry. Results showed
that the cost of one hectare from irrigated cherry was higher by about 3 times
than the cost of one hectare of rainfed due to the raise in the cost of irrigation.
The study also showed that the profits of the irrigated profits exceeded that of
the rainfed cherry by about 2 times since the productivity of the irrigated
hectare is two folds more than the productivity of the rainfed hectare. It was
also shown that the effect of variable time on the space was positive, changes in
the spaces resulting from the effect of time was 95%, while the effect of time on
both the production and the yield was negative. The relationship between time
and all of the production and yields was weak (8%).
