Generating effective employment opportunities is one of the principal challenges faced by development planners in Iran. If investment projects are undertaken on the basis of sectoral priorities in production and employment, the economic and social problems emanating from unemployment will be reduced, helping the Country''''s process of development. In this paper, an attempt is made to identify key sectors in terms of generating output and employment in the economy of Iran as a results of increased investment. The novelty of our approach is to demonstrate how inter-industry relations (input-output table), investment coefficients, and incremental labor-output and capital-output ratios can be integrated to accomplish the above objective. The empirical application of this approach has revealed the pronounced effect of investment on economic and employment growth potential of the service sector and some of manufacturing subdivisions like clothing and leather, other basic metal industries, food and textile manufacturing and wood paper and printing industries.خلاصه ماشینی:
"Since that time, numerous modifications of the basic procedures for establishing the key sectors and their use on data on different economies can be found in the literature (Strassert, 1968; Hazari,1970; Laumas,1975; Bharadway, 1976; Jones, 1976; Schultz, 1970 &1977, Rao and Harmston, 1979, Hewings, 1989, Dietzenbacher, 1992) It has also been proposed that sectors with strong FBL in their inter-industry relations have been to be stimulant to economic growth and development (Laomass, 1976; Meller et. In order to measure direct and indirect employment change in sector (j), the total demand directly and indirectly from sector (i) for the delivery of one unit of sector (j) output to its final demand (coefficients in column vector j in the standard Leontief inverse matrix) is multiplied in the slope (πj coefficient) of employment-production function of sector (i) and the results are aggregated over all sectors. Rather, the objective has been simply showing the relative importance (ranking) of economic sectors in their tendencies to generate employment opportunities in the overall economy by investing and the output expansion, through a quantitative employment forecasts, It should not be ignored that due to the absence of relevant detailed time series data on price indices, investment and employment as well as aggregation problem, assumptions and other model constraints, like fixing technology coefficients in the I-O table, the resulting empirical outcome (employment figures) can be different from what can actually be realized in the economy."
