the study of main factors in productivity growth of paddy producer provinces in iran

since the difference in productivity growth rates in different provinces is a result of regional inequality, efficiency criteria in the development of regional-scale agricultural activities is beneficial. therefore it is important that long-term movements in the provinces to identify differences in productivity levels to take effective measures such as investment more in infrastructure, research and development. be done. in this study, total factor productivity of paddy production and its related factors in major rice-producing provinces using nonparametric malmquist review and analysis was. the data used in this study type of panel data and related system costs production paddy in three provinces (mazandaran, gilan and golestan). the results showed, the average annual growth of total factor productivity in paddy production in total agricultural 86-1369 volume positive but low (1/5 percent per year) was. this figure is different provinces, so that gilan the highest rate of 6/7% in the year and province golestan and mazandaran are next in rank. study share factors productivity growth (changes in scale efficiency, pure technical efficiency and technology) that the scale efficiency of paddy production in golestan province of only two in any other role in increasing efficiency. the mazandaran and gilan, effect of technology more than two have any other increase productivity. with note to the results in this study, the formation bank needs research interest productivity in map institutions related to agricultural sector, in priority insert province that of comment growth advantage productivity in status good the are not policy development countries, interest making technology find new with with education and services consultancy complementary and more attention to training and advice farmers on proper use of resources, is recommended.
