چکیده مقاله :

در این مطالعه، برای بررسی اثر تغییرات قیمتی و درآمدی بر الگوی مصرف کنندگان شهر شیراز، از سیستم تقاضای تقریباً ایده آل درجه دو استفاده شده است. داده های تحقیق با استفاده از پرسشنامه و مصاحبه با گروه های درآمدی مختلف بدست آمده است. یافته های این تحقیق نشان داد که میان انواع برنج‌های داخلی رابطه جانشینی، میان برنج‌های وارداتی نیز رابطه جانشینی وجود دارد و رابطه میان برنج های داخلی و وارداتی مکملی است. بنابراین انواع برنج‌های داخلی و وارداتی هر کدام جداگانه به صورت جایگزین جهت توزیع بین مصرف‌کنندگان خود وارد بازار می‌شوند. مصرف‌کنندگان نیز با توجه به سلیقه ها و قدرت خرید، برنج مورد نظر خود را تقاضا می‌کنند. در مواردی نیز که اقشار مختلف جامعه با قیمت بالای برنج های داخلی مواجه هستند و قادر به مصرف یکدست برنجهای داخلی نمی باشند، برنج‌های هندی و پاکستانی که خوش‌پخت و دانه بلند هستند را خریداری ‌کرده و هنگام پخت، برای ایجاد طعم و عطر مناسب، مقداری برنج ایرانی به آن اضافه می‌کنند.  

چکیده انگلیسی:

This study aims to determine the effects of income and price changes on consumption pattern of rice in Shiraz city. To achieve this objective, quadratic almost ideal demand system was used. Different varieties of rice, including Pakistani, Indian, Thai, and domestic rice (Tarom local, Daylamani Tarom, Amol 3, Fajr, Aurora, Kadvs, Caspian) were considered. Findings of the study showed that various varieties of domestic rice were substitutable, and also imported varieties of rice were substitutable, while relationship between domestic and imported rice was complementary. Consumers demand is related to their tastes and purchasing power. Analysis of demand indicated that people with the high income prefer to buy domestic rice, while low income consumers prefer to buy imported rice mainly due to its low price.
