چکیده مقاله :
The demand for organic products has increased in the past decade due to concerns about the environmental and health issues of food products. This study provides marketing data on consumer preferences and willingness to pay (WTP) for organic rice in Babol County, Northern Iran. The main objective of this study was to estimate urban consumers' WTP for organic rice and to determine the main factors that consumers look for when purchasing rice. The contingent valuation method (CVM) and double bounded dichotomous (DBD) questionnaire were used to achieve the study goals. The results of the logit model showed that level of education, cancer history, and insurance history had statistically significant effects on WTP. The expected WTP for 1 kg of organic rice was 152467.33 IRR. Based on the average exchange rate of six months of 2018 (33500 IRR) per family in the study tends to the monthly equivalent of US$ 4.55 of their income to buy organic rice allocated. As a result, the total economic value of organic rice was US$ 2254893.072. These results provide important information about market opportunities and policy implementation regarding the production of organic crops.
در یک دهه گذشته به دلیل نگرانی در مورد مسائل زیستمحیطی و بهداشتی مربوط به محصولات غذایی، تقاضا برای محصولات ارگانیک افزایش یافته است. این مطالعه دادههای بازاریابی در مورد ترجیحات مصرفکننده و تمایل به پرداخت (WTP) برای محصول برنج ارگانیک در شهر بابل در شمال ایران را ارائه میدهد. هدف اصلی این مطالعه برآورد تمایل مصرفکننده شهری برای پرداخت برنج ارگانیک و تعیین ویژگیهای اصلی مصرفکنندگان در هنگام خرید برنج ارگانیک است. روش مورد استفاده برای رسیدن به هدف، روش ارزشگذاری مشروط (CVM) با استفاده از یک تابع احتمال لجستیک و پرسشنامه دوگانه دوبعدی (DBD) است. نتایج مدل لاجیت برای برنج ارگانیک نشان داد که متغیرهای سطح تحصیلات، سابقه سرطان در خانواده، سابقه بیمه، درآمد، قیمت پیشنهادی و مصرف محصولات ارگانیک از نظر آماری معنیدار و اثرگذار بر تمایل به پرداخت مصرفکنندگان هستند. نتایج مطالعه ما نشان داد که میانگین تمایل به پرداخت برای یک کیلوگرم برنج ارگانیک 33/152467 ریال برآورد شده است. براساس میانگین نرخ ارز شش ماهه سال 2018 (33500 ریال) برای هر خانواده مورد مطالعه، ماهیانه معادل 55/4 دلار از درآمد آنها برای خرید برنج ارگانیک اختصاص مییابد. در نتیجه، کل ارزش اقتصادی برنج ارگانیک 2254893.072 دلار است. این نتایج اطلاعات مهمی در مورد فرصت‌های بازار و همچنین اجرای سیاست‌های مربوط به تولید محصولات کشاورزی ارگانیک ارائه میدهد.
