ملخص المقالة :
مقدمه و هدف: اثربخشي سياست‌هاي مختلف اقتصادي همواره بستگی به شناخت کامل از ساختار تقاضا و الگوي مصرف خانوار داشته است. لذا تخمین تقاضا و برآورد کششهای مختلف، تاثیر بسزایی بر امنيت غذایی، سلامت و رفاه مصرف‌کنندگان دارد.
مواد و روشها: در این پژوهش به منظور تخمین سیستم تقاضا از سیستم تقاضای تقریبا ایدهآل درجه دوم با لحاظ متغیرهای دموگرافیک، استفاده شد. بدین منظور، دادههای خام طرح هزینه و درآمد خانوار مربوط به سال 1399 مورد استفاده قرار گرفت.
یافته ها: نتایج نشان میدهد که تمامی کششهای جبرانی و غیرجبرانی خودی تقاضای خانوارهای روستایی و شهری در سال 1399 منفی و قدر مطلق آنها کمتر از واحد هستند؛ در نتیجه همگی از کالاهای ضروری به شمار میروند. همچنین نتیجه ی کشش مخارج گوشت قرمز، قند و شکر و شیر برای همه خانوارها و روغن و حبوبات برای خانوارهای روستایی بالاتر از یک و کشش مخارج سایر گروهها مثبت و کمتر از واحد بوده است.
بحث و نتیجه گیری: با توجه به اهمیت گروه «گوشت»، توجه به الگوي قيمت‌گذاري اين كالا در سبد مصرفي خوراكي خانوارها از اهمیت ویژهای برخوردار است. همچنین با توجه به اثر درآمدی بالای این گروه، پيشنهاد ميشود با افزایش قیمت این کالاها، براي دستيابي به سطح رضايت اوليه بيشترين كمك حمايتي از اين گروه خوراكي اعمال شود.
