1.Introduction
“Crops” account for the bulk of foreign trade in agriculture and a major share of the household basket. Therefore, issues related to maintaining the production capacity and economic potential of this sub-sector can affect the country's economy. Cultivation area is one of the important dimensions of the agricultural process that the beneficiary can make the best use of this cultivation area by using science, knowledge and technology, and get a satisfactory product. In this article, we try to examine the effects of economic variables on the crops area in six provinces of Iran, which are geographically adjacent to each other. Based on the information obtained from the study of the subject records, the present study is the first study in terms of subject and method that has been done with the method of spatial econometrics in the country.
2.Methodology
In this study, spatial data model has been used to investigate the economic factors affecting the crop area in six provinces of Iran that had a dry climate in the period 2013-2018. The scope of this research is Isfahan, Sistan and Baluchestan, Fars, Kerman, Hormozgan and Yazd provinces. The main issue of the research was examined in the form of spatial analysis. According to the theoretical foundations and model of spatial econometrics, the model of this research is Spatial Durbin Model. Also in this study, the direct effects and indirect effects of explanatory variables were estimated.
3. Results and Discussion
The results of spatial durbin model analysis showed that income distribution in rural areas, income distribution in urban areas, inflation rate, unemployment rate, urbanization rate, youth population ratio, economic participation rate and gross domestic product are factors affecting the crop area in the provinces under review. The results also indicate the significance of direct effects and overflow effects based on indirect effects.
4.Conclusion
In government support services, attention should be paid to the characteristics of farmers' land, such as the area under cultivation, tools and equipment of farms. Given that the youth ratio has a positive and significant effect on the level of cultivation, it is recommended to managers and planners of the agricultural sector. For more youth to participate in the agricultural sector, support, arrangements and incentives should be provided to provide more production.
Based on the results of this study on the level of cultivation and the significant effect of this factor on agricultural production, people and officials are advised to try to maintain and exploit reasonable land suitable for agriculture, because the revitalization and enrichment of land that has been repeatedly cultivated and cultivated. Made from minerals and salts, it is very expensive.
