تعیین بخش‌های کلیدی استان یزد برمبنای تحلیل داده – ستانده دو منطقه‌ای

کمبود منابع در کشورهای مختلف بخصوص کشورهای در حال توسعه، نشان از اهمیت شناسایی بخش‌های کلیدی برای اقتصاد این کشورها و از موضوعات مهم برای برنامه‌ریزان و سیاست‌گذاران اقتصادی است. بدین منظور، هدف از پژوهش حاضر، شناسایی بخش‌های کلیدی اقتصاد استان یزد و سایر اقتصاد ملی بر مبنای مدل داده   - ستانده دو منطقه‌ای بوده و جدول داده   - ستانده دو منطقه‌ای استان یزد و سایر اقتصاد ملی بر اساس روش سهم مکانی sflq ‌ از جدول داده   - ستانده ملی سال 1395 بانک مرکزی استخراج، و سپس با استفاده از روش‌های سنتی‌، از طریق کشش تقاضای نهایی ستانده و تحلیل پوششی داده‌ها، به شناسایی بخش‌های کلیدی پرداخته شده و نهایتاً، با بهره‌گیری از شاخص چندرتبه‌ای (mri)، یک تعریف همزمان از نتایج ارائه شده است. در یک جمع‌بندی کلی از نتایج، بخش‌های کلیدی استان یزد، صنعت محور هستند. همچنین نتایج حاصل، اشاره به تفاوت در بخش‌های کلیدی با توجه به رویکرد برنامه‌ریزی منطقه‌ای هر منطقه دارد که به شناخت درست پتانسیل‌ها و توانایی‌های هر منطقه منجر خواهد شد.

determining the key sectors of yazd province based on multi regional input-output table

introduction: in order to evaluate the socioeconomic development, various criteria are used to evaluate the livelihood, welfare, and social changes of human life. the economic progress is one of the important dimensions of development. the social dimension of development, which leads to the creation of justice for different members of a society, is another important aspect of development, and the realization of this goal requires planning. land planning, which seeks to pay attention to regional potentials and differences, is a step in this direction. ignoring these capabilities will lead to resources waste, intensifying regional dualities and negative consequences. for this purpose, the aim of the current research is to identify the key sectors of the economy of yazd province based on the multi-regional input-output table. the innovation of the current research is to investigate all the economic activities of yazd province and national economy and to identify the key parts of the two regions. methodology: in the current research, we seek to identify and evaluate the key economic sectors of yazd province and national economy using traditional methods, elasticity of final demand, data envelopment analysis (dea) and finally a multi-ranked index using multi regional input-output table. in this article, the central bank’s 2016 input-output table was used, which was the most up-to-date official statistical data table approved and available at the time of the research. also, the regional input-output table of 2015 yazd province and national economy has been extracted from the updated input output table of central bank and regional accounts of the same year by using specific flegg location quotient (sflq) method. the input-output table of the central bank, according to the production and economic structure of the two regions, and using the isic classification method, has been aggregated into 20 sectors.results and discussion: the results of the present research show that in the traditional method, in total, the section manufacturing metal factory products except machinery and equipment and three sections manufacturing paper and paper products and printing, manufacturing products from rubber and plastic and manufacturing metals basic are respectively known as the key sectors of yazd province and other national economies. in the final demand elasticity method of yazd province, the sections manufacture of motor vehicles and other transportation equipment, manufacture of clothing, processing and dyeing of fur, tanning and polishing of leather and other leather products and manufacture of unclassified machinery and equipment in other and for the rest of the national economy, the sectors manufacturing textiles, manufacturing basic metals and manufacturing non-metallic mineral products are ranked first to third. in the third method, known as data envelopment analysis method, in yazd province, the manufacturing of motor vehicles and other transportation equipment sector and in other national economies, the manufacturing of paper, paper products and printing sector are known as key sectors.in a general summary using a multi ranking index (mri), in yazd province, textile manufacturing, clothing manufacturing, fur processing and dyeing, tanning and polishing of leather and other leather products, wood manufacturing and wooden products, coke manufacturing, products from the refining of petroleum and nuclear fuels and the manufacture of chemical materials and products, manufacture of basic metals, manufacture of machinery and equipment not elsewhere classified, manufacture of motor vehicles and other transport equipment, manufacture of furniture and articles not elsewhere classified, water, electricity and gas, construction, transportation and at the level of other national economy sectors clothing manufacturing, processing and dyeing of fur, tanning and polishing of leather and other leather products , making wood and wooden products, making paper, paper products and printing, making rubber and plastic products, making basic metals, manufacturing, repairing and installing subsidized, electronic and optical products, manufacturing, repairing and installation of electrical equipment”, “manufacture of furniture and articles not elsewhere classified” are identified as key sectors.conclusion: the findings of the present research indicate that the use of different criteria can show a different picture of the economic performance of the sectors. using traditional methods, key sectors are industry-oriented. in the final demand elasticity method, the priority of the sectors is determined based on the importance of each sector, and in the data envelopment analysis method, the results are estimated based on the efficiency value of each sector. these results show the importance of paying attention to choose the right method in the evaluation of key sectors. although the key sectors determined using different methods are different, the common point of all three methods is that the key sectors of yazd province are industry-oriented. therefore, according to the criteria used in the three methods, it can be seen that the province is well industrialized and the role of industry in the economic structure of the province is dominant.
