Abstract

In this study, the Input- Output Structural Decomposition Analysis (I-O SDA) is used to investigate the effects of technological structure changes on changes of total output in Sistan and Baluchestan Province during 2006-2011. The technological structure change is decomposed into two factors: intermediate input structure changes (input substitution) and change in direct backward linkage. The results show that the effect of changes in direct backward linkage is negative in all sectors, but the effect of input substitution in twelve sectors is positive and in other nine sectors is negative. Input substitutions in "Agriculture" and "Transport" sectors have the main positive effect on total output of the region and in ''Food industries'' and ''Restaurants & Hotels'' have the main negative effect on total output. This factor caused 20.89 billion Rials decrease in total output of region. Changes in direct backward linkage caused 8270.89 billion Rials decrease in total output of the region.

Abstract [Persian]

در این مطالعه از تحلیل تجزیه ساختاری در الگوی داده- ستانده برای بررسی اثر تغییر ساختار فناوری بر تولید کل در استان سیستان و بلوچستان در دوره 1385-1390 استفاده شده است. تغییرات ساختار فناورانه به دو عامل  تغییر در ساختار نهاده‌های واسطه‌ای (جانشینی نهاده‌ها) و تغییر در پیوند مستقیم پیشین تجزیه شده است. نتایج نشان می‌دهد که اثر تغییر پیوند مستقیم پیشین در همه بخش‌ها منفی بوده است؛ ولی اثر جانشینی نهاده‌ها در دوازده بخش دارای اثر مثبت و در نه بخش دیگر دارای اثر منفی بوده است. جانشینی نهاده‌ها در بخش‌های "کشاورزی" و "حمل و نقل" بیشترین اثر مثبت بر تولید کل منطقه را داشته است و بخش‌های "صنایع غذایی" و "هتل و رستوران" بیشترین اثر منفی را داشته است. این عامل موجب کاهش 89/20 میلیارد ریال در تولید کل منطقه شده است. تغییر در پیوند مستقیم پیشین موجب کاهش تولید منطقه به مبلغ 89/8270 میلیارد ریال شده است.
