چکیده

در بخش‏های مختلف اقتصادی، تأثیر آزادسازی تجاری بر وضعیت آلودگی محیط زیست در ایران به یکی از چالش‏ های پیش روی سیاست‏گذاران تبدیل شده است. در مطالعه حاضر، با استفاده از سه شاخص «سطح تجارت بین‌الملل در بخش کشاورزی»، «ادغام تجارت بین‌الملل در بخش کشاورزی» و «درجه باز بودن تجارت در بخش کشاورزی» و در قالب الگوی هم ‏انباشتگی جوهانسن- جوسیلیوس تصحیح خطای برداری (VECM)، به بررسی تأثیر شاخص ‏های آزادسازی تجاری درون‏ بخشی کشاورزی بر تخریب محیط زیست در ایران پرداخته شد. نتایج نشان داد که هر سه شاخص آزادسازی تجاری درون‏ بخشی کشاورزی بر تخریب محیط زیست اثر منفی و معنی دار دارند؛ همچنین، شدت مصرف انرژی در بخش کشاورزی و ارزش افزوده در این بخش باعث افزایش تخریب محیط زیست می ‏شوند. پیشنهاد می شود که دولت با حمایت از تولید محصولات کشاورزی با مزیت نسبی بالا در راستای کاهش تخریب محیط زیست، به کشت فراملی توجه بیشتری داشته باشد.

چکیده [English]

Impact of trade liberalization in different economic sectors on environmental pollution in Iran has become one of the challenges faced by policymakers. This study aimed at investigating the effects of agricultural intra-sectoral trade liberalization indexes on environmental degradation in Iran using the indexes of level of international trade (LIT), integration of international trade (IIT) and agriopenness in agriculture sector within Johansen-Juselius cointegration model (VECM) for the period of 1981-2015. The study results showed that all of these three indexes had significantly negative effects on the environmental degradation; also, intensity of energy consumption in agriculture sector and value added in this sector caused an increased environmental degradation. Finally, it was suggested that the government should pay more attention to transnational and extraterritorial cultivation while supporting the agricultural products with high relative advantages and less degradation impact on the environment of the country as well.
