چکیده

قدرت بازار را می‌توان به عنوان توانایی یک بازیگر جهت کسب سودهای اقتصادی بالاتر از نرمال دانست که ناشی از عواملی چون موانع ورود به بازار، مسائل کارائی بازار ، مزیت های حق ثبت و اختراع و غیره می‌باشد. در سال 1395سهم محصولات کشاورزی از صادرات غیرنفتی ۵/ ۱۳ درصد است که از این رقم سهم صادرات خرما ۴ درصد می‌باشد. با توجه به اهمیت این صنعت، این مقاله بر آن است تا به سنجش قدرت بازاری در این صنعت با توجه به نااطمینانی قیمت محصول بپردازد. داده های مورد نیاز این پژوهش در بازده زمانی1380 تا 1395و از طریق سازمان جهاد کشاورزی و مرکز آمار ایران جمع آوری گردید. به منظور بررسی قدرت بازار و حاشیه بازاریابی خرما در استان خوزستان از چارچوب نظری اودنل استفاده شده است. روابط بلندمدت و کوتاه‌مدت نیز با استفاده از مدل خودتوضیح با وقفه های گسترده (ARDL) و مدل ضریب تصحیح خطا (ECM) بدست آمده است. یافته‌های تحقیق نشان می‌دهد که رفتار تعیین قیمت در بازار سطوح مزرعه و خرده‌فروشی خرمای استان رقابت ناقص است.

In 1395, share of agricultural products in non-oil exports was 13.5 percent, of which the share of dates export was 4 percent. Considering the importance of this industry in country and the issues that have been addressed in the marketing and marketing of dates in Khuzestan, which is the main hub for the export of palm products, this paper seeks to measure market power in this industry due to price uncertainty. required data were collected during the period 1380 to 1395 through the Agricultural Jihad Organization and Statistics Center of Iran. In order to study dates market power and marketing margin in Khuzestan province, the theoretical framework of O'Donnell is used. Long-term and short-term relationships are also achieved using the ARDL and Error Correction Models. The results show that price determination behavior in farm and retail markets in this province is imperfect competition.
