In the study attempts to analyze soybean production and possibility obtaining biogas from soybean biomass, in order to obtain energy inputs into the profit function and realized a circular economy. This paper presents the results of fiveyear studies of soybean production analysis in the world and in Serbia, and was also examined soybeans morphoproductive characteristics and on the biogas yield, of the Favorit variety, produced in Pancevo, Serbia. Serbia has excellent conditions for soybeans production. The maximum soybean biomass yield of soybean variety Favorit was 5 t ha-1. The average biogas yield, for tested five years, was 368 m3ha-1. The biogas yield was in positive statistically significant correlations on the plant height (r=0.65*) and in positive correlations with biomass yield. Soybean cultivar with their characteristics justify the sowing and can be used as a raw material in bio-fuels production.
本研究试图分析大豆的生产和从大豆生物质中获取沼气的可能性,从而获得能量输入到利润函数中,实现循环经济。本文介绍了世界和塞尔维亚大豆生产分析的五年研究结果,并对塞尔维亚潘切沃生产的Favorit品种的大豆形态生产特征和沼气产量进行了研究。塞尔维亚的大豆生产条件很好。大豆品种有利号的最大大豆生物量产量为5 t ha-1。经过5年的测试,平均沼气产量为368立方米/公顷。沼气产量与株高呈显著正相关(r=0.65*),与生物量产量呈显著正相关(p < 0.05)。大豆品种以其特有的性状适合种植,可作为生物燃料生产的原料。

The purpose of this paper is to prove possibility of the application of the sociometric method in human resources management with the aim of appointing managers in one organization. Based on the some results, published in the scientific papers, authors established general and particular hypothesis about applying sociometry as a research method in human resources management. The concrete research of the applications of sociometry for appointing managers was conducted in one company in Serbia. Sociometric research shows real relations in a social group, as well as the projection of the position of individuals, mutual attraction and rejection within the group. Presented research is one of the “pioneering” attempts of broader application of the sociometric method in human resources management with the aim of appointing managers in one organization, especially in Serbia.
本文的目的是证明社会计量方法在人力资源管理中应用的可能性,目的是在一个组织中任命经理。基于发表在科学论文中的一些结果,作者建立了将社会计量学作为人力资源管理研究方法的一般性和特殊性假设。在塞尔维亚的一家公司对社会计量学在任命经理方面的应用进行了具体研究。社会计量研究显示了社会群体中的真实关系,以及个体地位的投射、群体内的相互吸引和排斥。所提出的研究是在人力资源管理中更广泛地应用社会计量方法的“开创性”尝试之一,目的是在一个组织中任命管理人员,特别是在塞尔维亚。

The article aims to identify the territorial distribution of the projects contracted within the operational programsthat form an integral part of the Cohesion Policy 2014 - 2020. The analysis is performed in the context in which the territoriality of the investments financed by the Cohesion Policy represents an important variable for ensuring its success. In this article, we proceeded to identify the investment profile used by each county, profile exposed based on a methodology of calculation based on the themes financed by each operational program respectively of the projects contracted at the level of each operational program. Two variables were used in the analysis, namely the number and value of the projects contracted until 30.09.2019. The article highlights the existence of a significant territorial concentration of the projects contracted at the level of a small number of counties. Also, the infrastructure and regional development are the needs considered to be the most present at the level of the projects contracted at the level of Cohesion Policy.
本文旨在确定运营计划中签约项目的地域分布,这些项目是2014-2012年凝聚力政策的组成部分。分析是在凝聚力政策资助的投资的地域性是确保其成功的重要变量的背景下进行的。在这篇文章中,我们着手确定每个县使用的投资概况,根据每个运营计划资助的主题和在每个运营计划层面承包的项目的计算方法,暴露出的概况。分析中使用了两个变量,即截至2019年9月30日签订合同的项目数量和价值。这篇文章强调,承包的项目在领土上明显集中在少数几个县。此外,在凝聚力政策层面承包的项目中,基础设施和区域发展被认为是最重要的需求。

Evaluating effectiveness of payments for forest ecosystem services by propensity scores analysis 通过倾向得分分析评估森林生态系统服务支付的有效性
IF 0.6 Q4 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2020-03-25 DOI: 10.5937/ekopolj2001087n

The Vietnamese Government have been implementing the Payment for Forest Ecosystem Service (PFES) since2008 with the aim of both improving natural forest status and enhancing income for mountainous community. Yet, effectiveness of the PFES scheme is now debated because of the shortage of experimental studies. So, the overall purpose of this study is to measure the effectiveness of the PFES program by propensity scores analysis. To do so, the study randomly surveyed 469 households located in four districts across Quang Nam province and then estimated the Average Treatment Effect on Treated (ATET). It is found that: (1) the households within PFES had got a insignificantly higher income than those without PES in the short-run; (2) yet, PFES was effective in long-run due to the improvement on income for participants; (3) PFES had an important role in increasing income inequality. Although this study demonstrated reasonable results, some limitations still exist due to the objective reasons, thus more studies with alternative methods should be conducted to confirm the results of this study for better policies.
自2008年以来,越南政府一直在实施森林生态系统服务付费,目的是改善天然林状况,增加山区社区的收入。然而,由于缺乏实验研究,PFES计划的有效性现在备受争议。因此,本研究的总体目的是通过倾向得分分析来衡量PFES计划的有效性。为此,该研究随机调查了广南省四个区的469户家庭,然后估计了平均治疗效果(ATET)。研究发现:(1)在短期内,PFES内的家庭收入略高于没有PES的家庭;(2) 然而,PFES从长期来看是有效的,因为参与者的收入有所提高;(3) PFES在加剧收入不平等方面发挥了重要作用。尽管这项研究证明了合理的结果,但由于客观原因,仍存在一些局限性,因此应采用更多替代方法进行研究,以确认这项研究的结果,从而制定更好的政策。

In Eastern Serbia in the Timok Region, the cult of household hospitality is still fostered. The Timok region belongs to the underdeveloped parts of Serbia and starting from the fact that the growth of local economy capacity also leads to overall regional development, the development of rural tourism could contribute to the well-being of the region. The paper examines sustainable development directions of rural tourism, taking into account the economic, environmental and social components, which are elements of sustainability. The authors apply Multi-CriteriaDecision-Making methods, ELECTRE as main, and AHP as an auxiliary method in the selection of an adequate and optimal solution. The aim of the paper is choosing the optimal projects for the development of rural tourism in the Timok region, based on well-defined criteria, among the several proposed projects.
在塞尔维亚东部的帖木克地区,对家庭好客的崇拜仍在滋长。蒂莫克地区属于塞尔维亚的欠发达地区,从当地经济能力的增长也会带来整个地区的发展这一事实出发,乡村旅游业的发展可能有助于该地区的福祉。本文考察了乡村旅游的可持续发展方向,同时考虑到了经济、环境和社会因素,这些因素是可持续性的要素。作者将以ELECTRE为主,AHP为辅的多准则决策方法应用于充分最优解的选择。本文的目的是在几个拟议项目中,根据明确的标准,选择提莫地区乡村旅游发展的最佳项目。

The aim and purpose of this paper is to point out to the quality of financial performance and efficiency of food retailers in Serbia, as well as measures for improvement in the future, based on theoretical knowledge and empirical analysis using AHP-TOPSIS methods. The problem of analyzing the financial performance of all companies, which includes trading companies, is very topical, significant and complex. Consequently, mathematical methods and models have lately been increasingly used. With this insight in mind, this paper investigates the financial performance and efficiency of food retailers in Serbia using AHP and TOPSIS methods. Of all the observed optimization criteria (cost of goods sold, operating costs, gross margin and net profit), the most significant was the cost of goods sold. The most efficient food retailer in Serbia is Aman. The Mercator-S Company is inefficient. In order to improve the efficiency of food retailers in Serbia, it is necessary to apply the Western business models (private brand, multichannel sales, organic food sales and others), the concepts of strategic management accounting and to strengthen the digitalization of business.
本文的目的和目的是在理论知识和AHP-TOPSIS方法实证分析的基础上,指出塞尔维亚食品零售商的财务绩效质量和效率,以及未来的改进措施。分析包括贸易公司在内的所有公司的财务业绩是一个非常热门、重要和复杂的问题。因此,最近越来越多地使用数学方法和模型。考虑到这一点,本文使用AHP和TOPSIS方法对塞尔维亚食品零售商的财务绩效和效率进行了调查。在所有观察到的优化标准(商品销售成本、运营成本、毛利率和净利润)中,最显著的是商品销售成本。在塞尔维亚效率最高的食品零售商是阿曼。墨卡托-S公司效率低下。为了提高塞尔维亚食品零售商的效率,有必要应用西方的商业模式(自有品牌、多渠道销售、有机食品销售等)、战略管理会计的概念,并加强业务的数字化。

The unique and at the same time very complex nature of the wine requires a more thorough selection process compared to other consumer products. Wine consumers are faced with a number of brands, grape varieties, and regions of origin, diverse tastes and prices. Using discrete choice experiment this study explores the importance that consumers in Serbia attach to five attributes of the local wine brands. Respondents were asked to evaluate 10 choice tasks, each with three different wines, and to choose the one that they would like to have with friends or family. The sample results indicate the high importance of the wine brand, while the price proved to be the least important. However, preference-based segmentation identified three clusters that differ primarily in the type of wine they favor, but also whether they like or not sweet and sparkling wines. It turns out that the price is a moderately important attribute in all clusters.
与其他消费品相比,葡萄酒的独特性和复杂性需要更彻底的选择过程。葡萄酒消费者面临着众多的品牌、葡萄品种、原产地、不同的口味和价格。使用离散选择实验,本研究探讨了重要性,在塞尔维亚的消费者附加到五个属性的当地葡萄酒品牌。受访者被要求评估10项选择任务,每个任务都有三种不同的葡萄酒,并选择一种他们想与朋友或家人一起喝的葡萄酒。样本结果表明,葡萄酒品牌的重要性很高,而价格被证明是最不重要的。然而,基于偏好的细分确定了三种不同类型的葡萄酒,主要是他们喜欢的葡萄酒类型,以及他们是否喜欢甜葡萄酒和起泡酒。结果表明,价格在所有集群中都是一个中等重要的属性。

Tsigai is an indigenous sheep breed present in entire Central and South-East Europe. Due to its low meat and milk production number of Tsigai sheep is in a sharp decline. But, there is a strong need to preserve valuable genetic resources of this breed. Therefore, the goal of this research is to evaluate economic performance of Tsigai breeding and to define strategies for its future use. In the paper profitability of Tsigai breeding is determined as well as economic efficiency of investments in Tsigai farms (using Net Present Value and Internal Rate of Return). To perform the analysis in risky circumstances authors applied sensitivity and decision tree approach. The results indicated that breeding of Tsigai sheep requires state subsidies to be profitable and economically efficient. Decision tree approach resulted in calclation of expected NPV. Investments in Tsigai farms proved to be economically efficient, but associated with high level of risk.
Tsigai是一种存在于整个中欧和东南欧的本土绵羊品种。由于其肉和奶产量低,赤改羊的数量急剧下降。但是,迫切需要保护这一品种宝贵的遗传资源。因此,本研究的目的是评价紫菜育种的经济效益,并为其未来的利用制定策略。本文确定了紫菜养殖的盈利能力以及紫菜养殖场投资的经济效益(使用净现值和内部收益率)。为了在危险环境下进行分析,作者应用了敏感性和决策树方法。结果表明,培育紫改羊需要国家补贴,才能实现盈利和经济效益。采用决策树法计算期望净现值。事实证明,在紫菜农场的投资具有经济效益,但风险很高。

The crucial aspect of mobilizing financial sources and savings to SMEs in the agribusiness sector and its supply chains towards sustainability and productive investment is of the most importance, what has motivated the research of this paper. Key findings of exploring the impact of two external sources of finance, trade credit and equity capital on the sustainability of the enterprises, are based on the literature review and the empirical research provided in Serbia in 2019. The positive influence of the researched sources of the financing as well as the conditions of this financing on the sustainability of these enterprises is confirmed. The contribution of the research results can be seen in the further improvement of the financial market framework for development of the external sources of finance, trade credit and equity capital in the context of entrepreneurial finance.
