an investigation of the effect of the development plans on iran’s mechanization evolution

the main goal followed in the present study is to investigate the effect of developed plans on mechanization evolution and employment in the agricultural sector. time series approach was applied. according to the results of the vec model, substitution relationship between machine and labor accepted. in general, one unit of mechanization coefficient is substituted for one million employments in agriculture sector. also, results showed that accomplishment of mechanization development programs had been affected by the improvement of its standing, but the existing gap between programs’ goals and their performance revealed inefficiency in acquiring iran’s vision programs. hence, exact implementation of development programs and an acquiring of the goals were considered as some of ways for reaching the optimum level of mechanization.
