Abstract
The balance between economic development and environmental sustainability is the most important determinant of sustainable development. Determining the optimal structure of the industry is one of the important factors affecting economic growth and the green economy. Therefore, the present study uses statistical evidence from Iranian provinces during the period 1400-1390 and the application of the spatial Tobit approach to examine the effect of industry structure on the efficiency of the green economy. The results of data envelopment analysis show that Kohgilouleh, Boyer Ahmad, and Isfahan provinces have the highest and lowest green economy efficiency indices with green efficiency values of 1 and 0.6, respectively. In addition, the size of the Ellison-Gleser index shows that Qom and Qazvin provinces have the highest industrial diversity and Bushehr province has the highest industrial concentration. Finally, the model estimation using the spatial Tobit method shows that industrialization and industrial concentration have reduced the efficiency of the green economy, but industrialization through the industrial concentration channel has reduced the efficiency of the green economy, and industrial concentration through the industrialization channel has increased the efficiency of the green economy. Therefore, increasing the share of industry in the economy and paying attention to industrial concentration based on the advantages of each province is the most important policy for improving the efficiency of the green economy.
