Measuring the sources of economic growth in Tehran province during the sanctions period; With a productivity approach (in Persian)

The growth and development of regions are influenced by the relationships among local, intra-regional, and inter-regional economic sectors, as well as by capacities and economies that differ somewhat at the national level. In the 2010s, despite international economic sanctions, Tehran experienced higher economic growth compared to the country. The average economic growth of this province was 3.1 percent, with 64.1 percent of that growth attributed to improvements in total factor productivity, while at the national level, productivity did not play a role in economic growth. From another perspective, 29.5 percent of Tehran's economic growth came from increased labor utilization, 6.4 percent from greater capital use, 12.1 percent from labor productivity growth, and 52 percent from enhanced capital productivity. These factors highlight the key role of productivity in the province's economic growth. Financial, economic, demographic capacities, specialized human resources, and access to markets have enabled Tehran's economy to remain strong even under sanctions and to utilize its capacities more effectively. The findings of this study provide insights that are significant for national, regional, and even local policymaking. The innovation of this study lies in improving the estimation of capital stock and identifying sources of economic growth, with an emphasis on agglomeration economies that distinguish Tehran from other regions.
