The Share of Value added of Economic Sectors in the Growth of GDP in the Fifth Development Plan

Sustainable economic growth and development is one of the main economic goals of countries. Achieving this basic goal requires comprehensive planning, the use of appropriate tools and the adoption of coordinated and adaptive policies in various economic sectors. The main purpose of this study is to investigate the impact of value added of various economic sectors on the growth of GDP during the Fifth Development Plan (2011-2016). The research model has been estimated using the panel data technique and a descriptive and analytical method has been used for the share of provinces in GDP. The results of applying econometric models using panel data show that the growth of sectors in the period has a positive and significant effect on GDP growth. As can be seen, the service sector has the largest share in GDP growth. Since most job opportunities in the service sector are based more on human capital and labor force than physical capital, the productivity in this sector increases at a very low rate compared to the other two sectors, and this will cause the cost price of services to increase higher than agriculture and industry, and this increases the share of that sector compared to other sectors of GDP. Therefore, it is necessary to pay special attention to this sector to increase employment.
