Abstract: The main objective of this study is to investigate the effect of Types the renewable energy production on Iran’s economic growth during the period of 2008-2017. For this analysis, Vector Autoregressive Model, Johansson-Juselius method and Vector Error Correction Model are used. In accordance with the obtained results, the effect of the variables’ coefficients is coincident based on the theoretical foundations and statistically significant. The results indicate that in the long run, the variables of renewable energy investment by the private sector, the power generation from the renewable energy, and the consumption of renewable energies, which are considered as indicators for renewable energies, have a positive and significant effect on the economic growth. The coefficient of the error correction method indicates that about 0.62 of the short-term imbalance is adjusted in each period to achieve the long-term equilibrium. Further, in the long run, a one percentage increase in the labor force variables, renewable energy investment by the private sector, electricity generation from renewable energy, and the Production of Types renewable energies) Wind, Solar, Hydro and geothermal) leads to 0.87, 1.17, 6.44, 4.29, 2.09, 1.78 and 1.56 percentage increase in the economic growth, respectivel and it became clear that It was found that among renewable energy sources, the effect of wind energy on growth is higher than other energies and we have to prioritize investment in wind energy. Therefore, according to the results of the research, the political recommendation is that, considering the process of the types of renewable energy sources in Iran, since wind energy has the greatest effect on economic growth compared to other energy sources. By investing in this unit, the share of renewable energy use in Iran could be increased Key words: Renewable energy, Economic Growth, Vector Error Correction Model and Johansson-Juselius method JEL: O13, C13, G21, C22

Unemployment had been one of the important challenges of recently decade in Iran,s economy. Food and drinking industry discharge the most important role in employment of industrial products of the country. In spite of large number of workforce in the agricultural sector, job creation potential is low in Mazandaran province so, development of non-agricultural sector should be prioritized in the region. In this province the high level of investment and employee are on these industries. This research wants to study the effect of employment in food and drinking industries, from the number of these industries and in Mazandaran province. Time series statistical data of employment (EM), number of firms (NF), the real investment (RIC), and payment to other inputs (ROIC) are used for 1991-2010. The methodology of research based on Fomby, for selection of suitable model, cause to estimate vector error correction model. The results acquired from Johansen and Juselius test show existence of long term equilibrium relation within these variables. Also results of vector error correction model show that in long term, if RIC and NF change one percent, employment increase by %0.139 and %2.329, but ROIC will decrease employment by %0.258.

In Lucas growth endogenous, we focus on human education that causes the weakness of decline return. Therefore the lack of autogenous technology cannot omit long term per capita growth. Human capital against autogenous growth model can be saved by investment i.e. people can choose how long they invest on education. So it is supposed that human capital is an accumulated input with fix return. Finally from the model concluded that in shortage of autogenous technical progress the long term growth rate can be explained by accumulation of human capital. In this paper it is tried to search the effect of human education on growth rate in Iran by Lucas growth endogenous. The model that has been used in this paper is estimated by time series of 1959-2007 and five steps co-integration approach of Johansson and Vector Error Correction Model. Finally, based on two obtained co-integrated vectors, it is concluded that in long term there is a positive relationship between index of knowledge oriented employment and increase of physical capital's accumulation on Iran's economic growth. In addition, both of these vectors show that knowledge oriented employment has been very influential in the economic growth of the country in the long term.
