چکیده

شکر از جمله محصولات اساسی و استراتژیک می‌باشد که همواره مورد توجه و حمایت دولت‌ها بوده است. این کالا یکی از کالاهای بین‌المللی و راهبردی است که جایگاه خاصی در سیاست‌های بازرگانی، اجتماعی و اقتصادی بسیاری از کشورها دارد. با توجه به اینکه بخشی از نیاز کشور از طریق واردات تأمین می‌شود، بنابراین یکی از موضوعات مهم در بازار شکر در کشور، متأثر بودن قیمت داخلی شکر از نوسانات تغییر نرخ ارز است که به‌تبع آن بر میزان تولید چغندرقند و شکر اثرگذار است. در این مطالعه تلاش شده است با استفاده از اطلاعات سری زمانی ماهانه 99-1397 به بررسی تغییر سیاست­های ارزی بر روی قیمت شکر اقدام گردد و همچنین با توجه به ارتباط واردات با تولید چغندرقند و شکر، نهایتاً تأثیر غیرمستقیم این سیاست بر تولید تحلیل شود. داده‌های ماهانه به‌منظور بررسی تغییر سیاست­های ارزی بر روی قیمت شکر از الگوی خود رگرسیون برداری VAR پردازش شده‌اند. نتایج حاصل از این بررسی نشان می­دهد، تغییر سیاست ارزی (تغییر نرخ ارز از 42000 ریال به ارز نیمایی) با وقفه دو ماهه بر روی قیمت شکر تأثیر مستقیم داشته است. با توجه بر رابطه علی بین متغیرها، هم‎چنین ملاحظه گردید که تغییر سیاست ارزی بر تولید چغندرقند نیز تأثیرگذار بوده است. با عنایت به نتایج حاصله از این تحقیق، به‌منظور پایداری اثر این سیاست در سال؜های آینده، لازم است در طراحی سیاست‌های مرتبط با این مسئله به نحو اثرگذاری به این متغیرها توجه ویژه شود. به‌طوری که از ابتدا همگام با اجرای سیاست، به عوامل مؤثر دیگر در این خصوص از جمله افزایش بهره‌وری عوامل تولید و حمایت از تکنولوژی به‌ویژه تولید بذر مناسب و اقتصادی برای تولیدکنندگان، بیش از پیش توجه شود تا روند فزاینده تولید در کشور، در مقابل واردات کاملاً حمایت شده شکر خارجی، پایدار بماند.

چکیده [English]

Sugar is one of the basic and strategic products that has always been considered and supported by governments. Sugar is an international and strategic commodity that has a special place in the trade, social and economic policies of many countries. Given that part of the country's needs is met through imports, therefore, one of the important issues in the sugar market in the country is the effect of domestic sugar prices on exchange rate fluctuations, which in turn affects the production of sugar beet and sugar. The aim of this study was to evaluate the effect of variation in foreign exchange policies on sugar price using the monthly time series data of 2018-20 and also due to the relationship between imports and sugar beet and sugar production, the indirect effect of this policy on production be analyzed. Monthly data were analyzed to using VAR model. Results showed that change in foreign exchange policy (exchange rate change from 42,000 Rials to the Nima currency) with a two-month break had a direct effect on sugar price. Due to the causal relationship between the variables, it was also observed that variation in foreign exchange policy has also affected the sugar beet production. Considering the results of this study, in order to sustain the effect of this policy in the coming years, it is necessary to pay special attention to the effect of these variables in designing related policies so that from the beginning with the implementation of the policy to other effective factors in this regard, including increase in the productivity of production factors and supporting technology, especially the production of suitable and economical seeds for producers, more attention should be given to the growing trend of production in the country against the import of sugar.
