Abstract

Technological change is one of the most important sources of the output growth not only on the supply side but also on the demand side of the economy. Because technological change in each economic sector causes input substitution among production inputs and this can influence growth of output in other sectors through the backward linkages. In the present study, the impact of technological changes of economic sectors on the production growth of four agricultural subsectors, from demand perspective, has been analyzed over 1986-2001 periods. To this end, structural decomposition analysis methodology has been utilized using input-output tables of the years 1986, 1991, and 2001. Following this approach and as a first step, output growth has been decomposed into three main components including, changes in final demand, import substitution, and technological change. Technological change effect has further been decomposed into individual coefficients and technological change effects in each economic sector on the growth of output in agricultural subsectors were calculated. Results indicate that growth of agricultural products is highly influenced by technological change in food industries which has been relatively livestock and poultry using and the other agricultural products saving. This result emphasizes the necessity of developing food industries for processing cropping, horticulture and fisheries products together with the development of livestock and poultry processing industry.
