ملخص المقالة :
از عوامل بسیار مهم در تعیین قیمت فرآورده های نفتی می توان به قیمت نفت خام و نرخ ارز اشاره کرد. نفت خام نهاده اصلی پالایشگاهها در تولید فرآورده های نفتی است و تغییرات نرخ ارز هم قیمت مورد انتظار تولیدکنندگان و تقاضا کننده ها و در نهایت فرآورده های نفتی را تحت تاثیر قرار می دهد، در این مقاله با بهره گیری از عوامل تاثیر گذار، با استفاده از روش همگرایی(FMOLS, CCR, DOLS) و برای دوره زمانی۱۳۹۲-۱۳۷۶ مدل قیمت فرآورده های نفتی مورد ارزیابی قرار می گیرد. نتایج برآورد نشان داد که در سه مدل( غیر از مدلی که نفت کوره به عنوان متغیر وابسته قرار می گرفت) قیمت نفت خام اثرات مثبت و معنی داری بر قیمت فرآورده های نفتی در بلند مدت دارد و در هر چهار مدل نرخ ارز اثرات مثبت معنی داری بر قیمت فرآورده های نفتی در ایران دارد. نتایج کوتاه مدت نیز نشان می دهد که روند حرکت متغیرها به سمت تعادل بلند مدت رضایت بخش می باشد. از نکات دیگر مورد بررسی در مقاله مقایسه اثر نسبی این دو متغیر بر قیمت فرآورده های نفتی می باشد که نتایج نشان می دهد ضریب نرخ ارز در مدلها بزرگتر از ضریب قیمت نفت خام است یعنی هر افزایشی در قیمت نفت خام، قیمت فرآورده ها را نسبت به نرخ ارز، بیشتر افزایش می دهد. بنابراین برای اقتصاد ایران تثبیت نرخ ارز و کاهش نوسانات آن، روند با ثبات تری در قیمت فرآورده های نفتی ایجاد خواهد کرد.
