Achieving economic growth and development is one of the most important concerns of any economic system. A developed financial system is considered one of the most important requirements for achieving sustainable economic growth and development; therefore, considering limited resources, financing investments, allocating and directing resources towards productive sectors and activities, and on the other hand, the necessity of increasing productivity and optimal use of production factors in order to achieve maximum economic growth efficiency and increase competitiveness in order to improve economic performance, is very important. Accordingly, the purpose of this study is to examine the effect of credit and productivity on the growth of value added of Iran's economic sectors by using seasonal time series data and using the generalized factor vector autovariance (FAVAR) approach in the time period q41402-q11391. According to the results of the study, the response of value added growth of economic sectors to credit and productivity shocks is not uniformly distributed in terms of timing and magnitude; In a way, the industrial sector has been more sensitive to credit and machinery capital formation, the agricultural sector to productivity, and the services sector to the exchange rate in a sectoral comparison.

Producers, who have lower efficiency in wheat production, can use the experiences of other producers and increase their efficiency over time. based on existing theories, probably producers with low initial levels of efficiency will have grown their efficiency faster than producers that have high levels of efficiency and a convergence over time will be between them. To investigate the convergence of cost efficiency, information on input prices, yield per hectare and production cost per hectare for irrigated wheat, were collected for 28 provinces in a 10-years period. By studying different methods of stochastic frontier cost function with panel data, "true random effects Model" of stochastic frontier method was selected. The model was estimated by using Simulation Halton method. Then Cost efficiency was calculated for each province. Beta and Sigma convergence test was conducted on cost efficiency. Results show that, changes of land rent (price) has the greatest impact and changes in the price of fertilizer per hectare has the lowest impact on production cost per hectare. Also, we find that There is Beta convergence (convergence of efficiency increase over initial levels) and Sigma convergence (convergence dispersion efficiency over time), between different provinces to improve cost efficiency in wheat production.
