چکیده

اثرگذاری متغیرهای اقلیمی بر تولیدات بخش کشاورزی در مناطق مختلف یکی از تمایزهای وابسته به اقلیم محسوب می‌شود که فرایند رشد و توسعه درونی بخش کشاورزی را تحت تأثیر قرار می‌دهد. در این مطالعه، با تجزیه و تحلیل آمار و اطلاعات استانی دوره زمانی 1390-1370، نقش تفاوت‌های اقلیمی در فرایند رشد بخش کشاورزی ایران با استفاده از رهیافت میانگین گروهی تلفیقی (PMG) بررسی شد. نتایج نشان داد که وجود تمایزهای اقلیمی در مناطق مختلف کشور باعث ایجاد تفاوت در نحوه بهره‌برداری از نهاده‌های انرژی، نیروی کار و زمین در مناطق مختلف کشور می‌شود و در نهایت تأثیر مهمی در فرایند رشد بخش کشاورزی در کشور از خود نشان می‌دهد. از این رو، در مطالعه حاضر پیشنهاد شد که سیاست‌گذاری‌های مرتبط با عوامل تولید بخش کشاورزی همچون قیمت‌گذاری عامل انرژی و تعیین دستمزد نیروی کار در این بخش با توجه به تمایزهای اقلیمی در مناطق مختلف کشور و با عنایت به آثار پدیده‌های مرتبط با اقلیم مورد نظر قرار گیرد.

چکیده [English]

The impact of climate variables on agricultural production in different regions is one of the climatic differences that affects the process of internal growth and development in the agricultural sector. In this study, with the analysis of provincial statistics during the period of 1991-2011, the role of climatic differences in the growth process of Iran agricultural sector was investigated using the integrated group average approach (PMG). The results indicated that climatic distinctions in different areas of Iran cause different levels of energy, labor and land usage and have a significant impact on agricultural growth process. Therefore, this study suggested to consider policies related to agricultural production factors such as energy pricing and labor wage determination according to the both climatic differences in all various regions of the country and the effects of the climate-related phenomena.
