- چکیده: 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.
- چکیده انگلیسی: 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:
- چکیده انگلیسی: Bioenergy is one of renewable energy types. The expansion of production this type of energy can create employment and sustainable income for society in addition to reducing pollution caused by fossil fuels and protecting the environment. Therefore, the purpose of this research was to investigate the preferences of sugar beet farmers in the north of Khuzestan province to the presumptive contracts of sugar beet planting to use in production of bioenergy. The statistical population of the research included 1890 sugar beet farmers of Khuzestan province in 2017-18 which 320 people were selected through the stratified sampling method. The required data were collected in person by referring to farmers and completing the questionnaire. Factors influencing the preferences of farmers were identified using the experimental approach of the attribute-oriented declared choice method to determine the important attributes of different sugar beet planting contracts and to estimate the conditional Logit regression model. The estimation results of the Logit model showed that coefficients related to the contract period, the area covered by the contract, the contract price, the cost-sharing in the contract, the product insurance in the contract and experience of sugar beet planting are positive and significant. The coefficient of the interaction of the variables of attitude to energy production, area under sugar beet planting, Experience of planting sugar beet and the area under sugar beet planting with ASC is significant and positive and the coefficient of the interaction of Farmer's risk attitude with ASC is significant and negative.
