In this article, it has been tried to investigate and analyze enterprise input_output model, the relationship between the main products of Khuzestan Steel Company with the internal departments of this company and also with the national economy on both the supply and demand sides and in the form of Backward and Forward linkage for the year 1400 by using the enterprise data model. Therefore, by compiling the enterprise input_output table of Khuzestan Steel Company, the production multiplier and the backward and forward linkages of the four products of slabs, billets and blooms, Pelletizing and sponge iron were calculated in the company and the national economy.The results of this research show that backward and forward linkage of Khuzestan Steel Company with the national economy is 3.21 and 1.41 units, respectively. Among the company's production activities, the highest link was related to the pelletizing product with 1.0 units and , the lowest link was related to the slab product with 0.55 units. pelletizing and sponge iron have the highest and lowest previous linkages (0.02 and 0.78 units) with the national economy, respectively. At the national level, rebar receives a large share of its demand from the products of the Khuzestan Steel Company, and ironstone is considered the most important consumable of these 4 products of the company.

Over the past decade, Iranchr('39')s economy has undergone a major and rapid experience of currency changes. One of the most important questions during the currency changes of the last decade is to answer the important question of how much the devaluation of the Rial has led to an increase in domestic prices and the extent to which these effects affect various dimensions of the domestic economy. Measuring the range of price changes in response to currency changes can be found in the phenomenon of currency transitions. The aim of this study is to analyze the inflationary effects of foreign exchange passage on the levels of imported and producer prices at different stages of production and separately in the productive sectors of the economy and also to determine the effective factors in foreign exchange passage by resorting to supply side variables in Iranchr('39')s economy. The present study presents a new approach for measuring exchange rate crossings on production chains by combining econometric tools and Input-Output table in embedding and separating the estimation of exchange rate pass coefficients in two stages on import and producer prices. Industry by using the tools of Input-Output table segmentation and considering variables based on information specific to each economic sector, such as; The import sector, the export sector, the production of each sector, provide sector linkages in estimating the exchange rate passage in the Iranian economy. These measures are based on three types of time series analysis, Input-Output analysis and Panel data analysis from 1986 to 2017. Findings of the research in stage 1 indicate the high dependence of many industrial and economic sectors of Iran on imports and low elasticity of imports to the exchange rate and no substitution by domestic products. In the second stage, the coefficients of exchange rate passage on the producer are positive and significant in almost all economic sectors, and this fact confirms the effectiveness of the producer price index in the Iranian economy from changes in the exchange rate (through imports). also; The passage of the exchange rate on producer prices varies between different years in different sectors, and in some economic sectors these changes have increased over time, which indicates the increasing dependence and increasing impact of import prices on producer prices over time. It is in the policies adopted. Also, the results in stage 3 indicate a negative and significant effect of export share coefficients and the natural logarithm of domestic production and have a positive and significant effect of share coefficients of intermediate import inputs and inter-sectoral linkages, but the share of intermediate imports among other variables. It has the highest impact on the exchange rate of economic sectors

This paper examines Iran’s maritime shipping industry’s stance globally, as well as its potential role in transforming the Iranian economy into a ‘resistive economy’. The maritime industry has the potential to realise some of the provisions of a resistive economy, specifically by playing a crucial role in increasing competitiveness globally, diversifying commercial partners _ especially by securing new import bases, forming new markets, developing strategic partnerships, reducing the vulnerability of the revenues from oil and gas exports by finding new strategic customers, increasing the export of gas, increasing the export of petrochemicals and increasing the export of oil products. A review of the maritime industry in Iran indicates that it has one of the biggest fleets in the Persian Gulf; yet, in terms of maritime connections indexes, despite the increase in recent years, it occupies a place below Saudi Arabia, Oman and the UAE (occupying the 40th place globally among countries with coastal borders). Input-outputs data from the Central Bank in 1378, 1383 and 1389 indicate that prior and subsequent linkages, the diversity of subsequent linkages and the potential for employment in the industry have developed. Hence, indicating that the sector could play a progressive role in the process of uneven growth. The share of domestically produced maritime equipment (including various types of ships), from all maritime equipment used has increased twofold, indicating increasing self-reliance of production in the industry, thus, taking a step toward realising economic resilience in the sector.

In this paper, financial services in the Iranian as a sector with a leontief production function, This sector buys inputs from other sectors for its productions and provides services to expedite the cash fellows and risk transformation to other sectors, The first relations are called backward linkage and the later relations are called forward linkage, for quantification of the linkage, employment and output elasticity of input-output table, The forward index of value added and backward linkage of final demand are used, Furthermore, direct and indirect effects of a hypothetical extraction of this sector on output and employment are countable, The results of research indicated that, by selection leontief method, if the backward and forward linkage effects of financial services sector are eliminate, decrease of employment will be 215,814 person, whereas, by selection Gosh method, decrease of employment will be estimated 687,037 person.
