- چکیده انگلیسی: Among Medical products, jujube (Ziziphus jujuba Mill.) is very important due to its very high nutritional value. Jujube as one of the most valuable medicinal plants can play an important role in Iran's non-oil exports. In spite of this fact, unfortunately, the production, distribution and marketing of this product are confronted with a number of obstacles. Therefore, this study can help for identifying the market layers challenges of this product in accordance with the production. Since, the retail price has a significant effect on the marketing margin, if the margin control and preventing its increase is desired, it is necessary to adopt appropriate strategies as applying continuous monitoring, and avoid volatility and rising of prices. It seems the pattern of changes in retail jujube prices is similar to the pattern of changes in producer prices. The retail-margin function is influenced by retail price, retailer cost and the wholesale margin. The results of estimating of the marketing margin function indicate that the marketing margin have a direct relationship with the retail price.

- چکیده انگلیسی: Abstract
Nowadays, fishery and aquaculture products form an important fraction of the protein requirement and food of many people on the earth. The hike in prices of these essential products seems necessary owing to the increase in demand and consumption of these products in the country. The price transmission from the international market to the domestic market of tunas was investigated in the present research. For this purpose, the elasticity of substitution between tunas imports with goods produced in Iran (Armington Elasticity) was calculated. Armington elasticity reflects a degree of substitution between commodities produced domestically and those produced abroad. A greater elasticity indicates that buyers did not discriminate between domestic and foreign produced commodities and the buyers considered them same. Therefore, any policy to influence the price of imported commodities will be effective in regulating the prices of commodities produced domestically. In the present study, in order to calculate the Armington elasticity, the annual data for the year’s between1974 - 2014 was used along with the technique of maximum entropy (ME). In addition to Armington elasticity, the least square estimated and vector error correction model (ECM) were estimated using entropy maximization. The results showed that Armington tension in the long-term was greater than that in the short-term. Even though this means the product has been imported, it however serves as an alternative for domestically produced commodities; therefore, buyers do not see any difference between them. Additionally, the prices of these products have been affected by global prices and the swings in global prices can be transported more easily in the long-term than in the short-term to the internal market for these products.- انتشار مقاله: 09-01-1395

- 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.

- چکیده انگلیسی: Background and aims: The main objective of this study was to investigate the factors affecting the achievement of the competitive advantage in the international markets for medicinal plants and related products in Zagros forests.
Methods: This is an applied descriptive/correlational research, because in addition to describing the current situation, its tests hypotheses are based on multiple regression method and determines the impact of variables using the inferential statistics method. In addition, it is an applied research since its expected results can be used to improve the international market of medicinal plants and related products in the Zagros forests. The study population included all customers of medicinal plants and related products in Zagros forests. Considering the fact that the population size is unlimited and undefined, the sample size formula was used. The method used in this research is the cluster sampling and available non-probability sampling. Initially, the Zone was divided into four parts: north, south, east and west. Then, the questionnaires were distributed. The sample size was calculated as 384 people utilizing sample size formula for unlimited population. In this research, the variables of interest were measured using researcher made questionnaires which were distributed among selected subjects whose views will be assessed on the variables. Finally, the collected data was analyzed using SPSS software.
Results: The results showed that medicinal plants, diversity of medicinal plants, and industrialization of medicinal plants and production of the most essential drugs even certain drugs would lead to the achievement of competitive advantage in the international market of medicinal plants and related products in the Zagros forests.
Conclusion: Paving the way for investment in the country will make great contribution to the export of medicinal plants products.- انتشار مقاله: 02-06-1395
