چکیده

گسترش صادرات غیرنفتی یکی از اجزای مهم صادرات در اقتصاد ایران به شمار می‌رود. در این راستا، کاهش ارزش پول داخلی به عنوان یکی از راه­های دست­یابی به این هدف مطرح است. هدف پژوهش حاضر ارائه‌ی بینشی جدید در رابطه با نحوه‌ی اثرگذاری نرخ ارز بر تورم کالاهای صادراتی غیرنفتی است. برای این منظور، از الگوی خورگرسیون برداری استانه‌ای استفاده شد تا موضوع عبور نرخ ارز طی سال‌های 1395:4 – 1376:2 به صورت غیرخطی بررسی شود. طبق نتایج پژوهش، تکانه­ی نرخ ارز با پاسخ مثبت شاخص تورم کالاهای صادراتی غیرنفتی همراه است. در عین حال، اثرگذاری تکانه­ی مذکور قبل و بعد از تورم فصلی 8/0 % متفاوت است. به گونه­ای که اگر تورم کالاهای صادراتی بیش­تر از آستانه باشد، واکنش مثبت و شدیدتری نسبت به تکانه­ی نرخ ارز خواهد داشت. این نتیجه را می‌توان به وابسته بودن فرآیند تولید به کالاهای واسطه‌ای وارداتی نسبت داد. بر این اساس، نمی‌توان انتظار داشت با کاهش ارزش پول ملی رقابت‌پذیری بین‌المللی برای صادرات غیرنفتی ایجاد شود.

چکیده [English]

Non-oil exports are one of the important components of the Iran’s export. In this regard, currency depreciation is one of the ways to achieve the higher level of non-oil exports. The purpose of the present study is to provide a new insight into the way the exchange rate influences the inflation of non-oil exports prices. For this purpose, a threshold vector autoregression model was used to study the non-linear issue of exchange rate fluctuation in 1376:2-1395:4. According to the results of the research, the exchange rate shocks is associated with a positive response to the inflation rate of non-oil exports goods. Nevertheless, the impact of the shock before and after the 0.8% seasonal inflation is different. So if inflation of exported goods exceeds the threshold, it will have a more positive reaction to the exchange rate shock. This result can be attributed to the dependence of the production of Exported goods on imported intermediate goods. Accordingly, creating international competitiveness of non-oil exports with currency depreciation cannot be expected.
