Effective Factors on Environmental Efficiency Rapeseed Cultivation in Provinces of Iran (Approch Spatial econometric)

To date, researches have presented numerous models for measuring environmental efficiency; however, reports suggested that they have not been able to consider the increasing spatial impact of certain factors affecting the environmental efficiency of agricultural products and for the most part the results are not logical.

In this study, first the environmental efficiency of rapeseed in designated provinces of Iran during the years 2011 to 2016 was measured and to evaluate the environmental efficiency of the specific measurement model was used. Then, in this study, using a Spatial Durbin Model, the factors affecting the environmental efficiency of rapeseed farmers (due to the utilization of water resources and other climatic aspects) in certain provinces of Iran have been investigated.

The results of this study showed that the average environmental efficiency of the entire country is about 0.73 during the mentioned period, which has increased with the relative improvement of environmental efficiency each year and also has spatial spillover effects. Direct and indirect effects indicate that domestic water consumption, degree of openness, technological progress in agriculture and industrial structure have a significant impact on the environmental efficiency of Iranian rapeseed growers.

In this regard, the government and citizens should focus on solutions such as reducing pollution, saving domestic water consumption and transforming the industrial structure. In addition, managers should consider the spatial effects of these factors when designing government policies.
