چکیده

شاخص قیمت مصرف کننده (CPI) و شاخص قیمت تولید کننده (PPI)، دارای مفاهیم مرتبطی هستند. روابط بین این دو ممکن است از نوع علی و یا غیر علی باشد. این پژوهش به بررسی رابطه علیت میان شاخص قیمت مصرف کننده(CPI) با شاخص قیمت تولیدکننده(PPI) طی دوره 1378:01 تا 1390:01 در ایران می پردازد. نتایج بدست آمده از روش علیت گرنجر نشان می دهد که PPI علیت گرنجری CPI بوده است. همچنین نتایج مدل تصحیح خطا نیز نتایج این آزمون را مورد تایید قرار می دهد.. نتایج مطالعه گویای این است که در اقتصاد ایران، عوامل سمت تقاضا نقش مهم تری نسبت به عوامل طرف عرضه دارا می باشند، گر چه دو طرف عرضه و تقاضا بر روند تورم داخلی که توسط CPI اندازه گیری موثر می باشند.
