The role of knowledge-based economic in the agriculture growth of selected countries with an emphasis on Iran

Introduction The paradigm transmission from traditional economic to knowledge-based economic is based on the production, distribution, and use of knowledge as a principal factor in all aspects of society. Improving and increasing agricultural productivity is the result of transferring from resource-based production systems to knowledge-based production systems. In the new patterns of agricultural development, science and technology play an important role in sustainable agricultural growth and development, and these patterns are referred to as scientific agriculture, knowledge-based agriculture and technology and knowledge agriculture. in this study, it tried to study the role of knowledge-based economic in agricultural growth of some selected countries with emphasis on Iran.     Materials and Methods In this study, we tried to study the role of knowledge-based economic in agricultural growth of some selected countries with emphasis on Iran, using fixed effects method and knowledge assessment methodology of the World Bank during the period of 2008-2017.To calculate the knowledge-based index was used the methodology of knowledge economy assessment by the World Bank Institute. Since the main purpose of the present study is to investigate the role of knowledge-based economy in the agricultural sector of selected countries with emphasis on Iran, besides considering the factors of capital and labor force which are also used in Solo growth model, Endogenous Growths in Explaining the Residual Component of Growth, The Role of Components of knowledge-based economy was been investigated. fixed effects method was used to investigate the role of knowledge-based economic in the agriculture growth of selected countries with an emphasis on Iran. Results and discussion The results showed that during 2008-2009, the average of knowledge-based economy index increased from 4.07 to 5, indicating a relatively "poor performance" of Iran in knowledge-based economy index. also, the results showed that the variables of capital stock, employment, and knowledge-based economic index have a significant and positive effect on the agricultural growth of selected countries. Out of the elasticities of capital stock (0.26), employment (0.075) and the of knowledge-based economics index (0.90), the most significant is related to the knowledge-based economy index, and it shows the importance of knowledge-based agriculture is important. Suggestion According to the result, science knowledge-based economic is one of the components of the resistance economy, Coordination between agricultural education and research activities is essential in order to move from resource-based agriculture to knowledge-based.  JEL Classification: O1, O4, O41.
