چکیده مقاله :

his study aimed to investigate factors affecting the revenue share of Iranian tomato paste exporting companies. Flexible estimation method was used on a two-dimensional panel data set including 224 observations from 14 tomato paste manufacturing and exporting companies and 16 importing countries during 2005-12. Results showed that value added per employee in manufacturing or exporting companies, and dummy variables (common border, religion and number of documents needed to import) had positive effect on the revenue share of a given company. The import tariff rates of selected countries and distance had a negative effect on the export revenue share of all companies. Accordingly, programmers and policy makers should provide background information about the productivity of labor force in these companies via researching, developing, and promoting production technologies, which will increase the exporting revenue share of this product. Furthermore, by making bilateral and multilateral contracts and agreements, the tariff rates can be reduced to increase the revenue share of the tomato paste export.

چکیده انگلیسی:

مطالعه حاضر به بررسی عوامل مؤثر بر سهم درآمد شرکت­های ایرانی صادرکننده رب گوجه فرنگی پرداخته است. روش تخمین انعطاف­پذیر برای یک مجموعه داده­های تابلویی دوبعدی شامل 224 مشاهده متشکل از 14 شرکت تولیدکننده و صادرکننده و 16 کشور وارد کننده درطی سال­های 91-1384 استفاده گردید. نتایج حاکی از آن بوده است که ارزش افزوده هرکارگر در شرکت­های تولیدکننده و صادرکننده و متغیرهای مجازی(مرز مشترک،مذهب و تعداد اسناد جهت واردات) اثر مثبتی بر سهم درآمد شرکت مفروض دارند. نرخ تعرفه وارداتی کشورها و مسافت اثر منفی بر سهم درآمد صادراتی تمامی شرکت­ها دارد. براین اساس برنامه­ریزان و سیاست­گذاران بایدپیش­زمینه درخصوص بهره­وری نیروی کار در این شرکت­ها ازطریق تحقیق،توسعه و ارتقاء فن­آوری تولید که موجب افزایش سهم درآمد صادراتی این محصول می­گردد، مهیا کنند. علاوه بر این، با ایجاد قراردادها و موافقت نامه­های دوجانبه، نرخ­های تعرفه می­تواند درجهت افزایش سهم درآمدی صادرات رب گوجه فرنگی، کاهش یابد.
