چکیده

هدف مطالعه حاضر ارزیابی اثراقتصاد دانش محور بر ارزش افزوده بخش کشاورزی ایران طی سال­های 1393-1368 بود. به منظور بررسی روابط بلندمدت بین ارزش افزوده بخش کشاورزی و متغیرهای شاخص ICT، شاخص R&D، شاخص ترویج و آموزش، سرمایه و نیروی کار از روش هم­انباشتگی جوهانسن- جوسیلیوس و الگوی تصحیح خطای ‌برداری(VECM)  استفاده شد. نتایج حاصل از تخمین تابع بلندمدت مدل مبین تأثیر مثبت و معنی­دار شاخص ICT، شاخص R&D، متغیرهای سرمایه و نیروی کار بر ارزش افزوده بخش کشاورزی بود. تأثیر شاخص ترویج و آموزش کشاورزی بر ارزش افزوده بخش کشاورزی مثبت اما فاقد ارزش آماری بود . علاوه بر این، نتایج حاصل از مدل تصحیح خطا نشان داد که حدود 53 درصد از انحرافات کوتاه مدت ارزش افزوده بخش کشاورزی از مقدار تعادلی بلندمدت آن طی یک دوره تعدیل می­شود. از این رو، افزایش اعتبارات تحقیق و توسعه در بودجه بخش کشاورزی می­تواند در رشد ارزش افزوده این بخش مؤثر باشد.

چکیده [English]

The purpose of this study was to evaluate the effect of knowledge-based economy on value added of Iran’s agricultural sector from 1989 to 2014. To investigate the long-term relationship between the value added of the agricultural sector and ICT index, R&D index, extension and education index, capital and labor variables, Johansen-Juselius Co-integration method and error correction model (ECM) were used. The results of long-term function estimation of the model show a positive and significant impact of ICT index, research and development index, and capital and labor variables on value added of the agricultural sector. The effect of agricultural extension and education index on value added of the agricultural sector was positive but it was not statistically significant. In addition, the results of error correction model show that almost 53% of short-term deviations of the agricultural sector value added from its long-run equilibrium are modified in a period. Hence, the increase in research and development credits in the budget of agricultural sector can be effective in growth of value added of this sector.
