The cyclical nature of hop market pricing has been recorded since the 16th century, but the effect had never previously been documented or quantified. Using Bayesian inference in an analysis of data regarding the US hop industry collected and published by the United States Department of Agriculture (USDA) it was possible to measure the change of inventory and acreage responsiveness to price during periods of free and markets regulated through the enforcement of intellectual property rights (IPR). The data demonstrated a delayed, reduced, or total lack of responsiveness in the change of direction of acreage and inventory in response to directional changes in season average price (SAP) during free market periods. This reaction was referred to as the delayed surplus response (DSR). The data also demonstrated the absence of the DSR during periods in which proprietary varieties reached greater than 50% of US acreage and production. Patented plant varieties offer a legal monopoly over that intellectual property (IP). The absence of the DSR during periods in which a majority of US acreage and production were proprietary indicated a strong degree of control over supply. By extension, the owners of proprietary varieties demonstrated the ability to influence price at desired levels.
自16世纪以来,啤酒花市场价格的周期性已经被记录下来,但这种影响以前从未被记录或量化。在对美国农业部(USDA)收集和发布的有关美国啤酒花行业的数据进行分析时,使用贝叶斯推理可以衡量在自由市场和通过执行知识产权(IPR)进行监管的市场期间库存和面积对价格的响应性的变化。数据显示,在自由市场时期,随着季节平均价格(SAP)的方向性变化,种植面积和库存变化的响应延迟、减少或完全缺乏响应。这种反应被称为延迟剩余反应(DSR)。数据还表明,在专利品种达到美国种植面积和产量的50%以上的时期,没有DSR。获得专利的植物品种提供了对知识产权(IP)的合法垄断。在美国大部分种植面积和产量为私有的时期,没有DSR表明对供应的控制程度很强。由此推及,专利品种的所有者表现出将价格影响到理想水平的能力。

Environmental strategies and their effects on firm performance are receiving increased attention in the literature, but the results are inconclusive. To fill this gap, we propose to evaluate the effect of environmental strategies on firm performance, thereby making two significant contributions. The first is the use of Bayesian techniques to estimate a stochastic frontier model with random coefficients to evaluate the relationship between environmental strategies and performance at the individual firm level, thus adequately incorporating heterogeneity; the second is the adoption of profit efficiency as a measure of firm performance. To test this idea, we studied the effect of a set of pollutants on profit efficiency in a sample of livestock firms in Spain. The results reveal that i) the success of environmental strategies depends on the properties and internal characteristics of each firm and the environment in which it operates and ii) the mean efficiency is 55.80%, which implies that these firms are losing on average 44.20% of their maximum potential profit. These results have significant strategic implications for firms' ability to achieve a competitive advantage.
环境战略及其对企业绩效的影响在文献中受到越来越多的关注,但结果是不确定的。为了填补这一空白,我们建议评估环境战略对企业绩效的影响,从而做出两个重要贡献。第一个是使用贝叶斯技术估计随机前沿模型与随机系数,以评估环境战略和绩效之间的关系在个别企业层面,从而充分纳入异质性;二是采用利润效率作为企业绩效的衡量标准。为了验证这一观点,我们研究了一组污染物对西班牙畜牧公司利润效率的影响。结果表明:1)环境战略的成功取决于每个企业及其经营环境的性质和内部特征;2)平均效率为55.80%,这意味着这些企业平均损失了最大潜在利润的44.20%。这些结果对企业获得竞争优势的能力具有重要的战略意义。

The role of small farms in agricultural production is particularly important for less developed economies, with a high share of agriculture in GDP and a lower level of national income. These economies have a high share of small-scale farms in the total number of registered farms, measured by the size of an agricultural holding. The paper thoroughly analyses the distribution channels of the agricultural products of Moldova (MDA), Romania (ROM), and Serbia (SRB). The data sources for this analysis are taken from the survey conducted on 1 608 small-scale farms in the above-mentioned countries in 2019. The aim of the paper is to develop a model that could enable the structured analysis of distribution channels. Analytical Hierarchy Process (AHP) method was used for efficient assessment and as a criterion for choosing the most appropriate distribution channel. The results of the analysis show that small-scale farms mostly place their products in green markets and processing plants and that the quality and the price of agricultural products are the dominant criteria for the selection of a channel. The results of the applied model indicate that the model is stable and that small-scale farms can choose the optimal distribution channel by using this study.
小农场在农业生产中的作用对欠发达经济体尤其重要,因为农业在国内生产总值中所占的份额很高,而国民收入水平较低。以农业控股规模衡量,这些经济体的小规模农场在注册农场总数中所占比例很高。本文对摩尔多瓦(MDA)、罗马尼亚(ROM)和塞尔维亚(SRB)的农产品流通渠道进行了深入分析。本分析的数据来源来自2019年对上述国家1608个小规模农场进行的调查。本文的目的是开发一种能够对分销渠道进行结构化分析的模型。采用层次分析法(AHP)进行有效评价,并作为选择最合适分销渠道的标准。分析结果表明,小规模农场大多将产品放在绿色市场和加工厂,农产品的质量和价格是选择渠道的主要标准。应用模型的结果表明,该模型是稳定的,可以帮助小规模养殖场选择最优的配送渠道。

Foreign trade and virtual land resources: A case study of China's grain 对外贸易与虚拟土地资源:以中国粮食为例
Pub Date : 2022-07-22 DOI: 10.17221/85/2022-agricecon

This paper selects four grain crops of rice, wheat, soybean, and corn, analyzes their foreign trade from 2002 to 2020, and estimates the virtual land resource. The research results show that China's grain has always been in the state of net import. China mainly exports rice and imports soybeans, and the market structure has an obvious trend of simplification. The net import of virtual land resources in China's grain has grown significantly and has outstanding contribution ability. The average annual net import is 62.25 million ha, which is almost equivalent to the arable land area of China's one-cropping area. The net import contribution of soybean virtual land resources is about 101 times of its sown area, while corn, rice, and wheat account for about 10.42, 11.69, and 74.66% of its sown area. The net importers of virtual land resources are relatively concentrated, mainly in Brazil, the US, Argentina, Ukraine, and Canada.
本文选取水稻、小麦、大豆、玉米4种粮食作物,对其2002 - 2020年的对外贸易进行了分析,并对虚拟土地资源进行了估算。研究结果表明,中国粮食一直处于净进口状态。中国以大米出口为主,大豆进口为主,市场结构有明显的简单化趋势。中国粮食虚拟土地资源净进口增长明显,贡献能力突出。年均净进口量为6225万公顷,几乎相当于中国一种作物的可耕地面积。大豆虚拟土地资源净进口贡献约为其播种面积的101倍,玉米、水稻和小麦分别占其播种面积的10.42%、11.69%和74.66%。虚拟土地资源净进口国相对集中,主要集中在巴西、美国、阿根廷、乌克兰和加拿大。

Increasing the work engagement of agrarian enterprise employees through the support of the direct manager, organisational trust and job autonomy 通过直接管理者的支持、组织信任和工作自主性提高农业企业员工的工作投入度
Pub Date : 2022-07-22 DOI: 10.17221/92/2022-agricecon

The aim of the paper is to research the interrelationships between variables – the support of the direct manager (SDM), work engagement (WE), organisational trust (OT), and job autonomy (JA) in enterprises operating in agriculture. Both direct and indirect effects affecting the increase in work engagement of agrarian employees are analysed. For the data collection, a questionnaire survey among the employees of agrarian enterprises in Slovakia was used (680 respondents). For testing, we applied the theoretical research model and purposed hypotheses with the partial least squares structural equation modeling (PLS-SEM) method through the SmartPLS 3.0 software. The findings point out the existence of a statistically significant relationship between SDM and WE, which is, though, weaker than the overall effect by involving the mediation variables. Both mediation variables (OT and JA) separately increase the overall effect, but their common mediation influence mainly has a substantial significance. The intensity of the researched relationship increases with the length of employment. In the case of the employee's age and the size of the agrarian enterprise, there was a negative moderating effect on the relationship of the main proven variables.
本文旨在研究农业企业直接管理者支持度(SDM)、工作投入度(WE)、组织信任度(OT)和工作自主性(JA)等变量之间的相互关系。分析了影响农业雇员工作投入增加的直接和间接影响。为了收集数据,对斯洛伐克农业企业的雇员进行了问卷调查(680名受访者)。为了验证,我们通过SmartPLS 3.0软件应用理论研究模型和偏最小二乘结构方程建模(PLS-SEM)方法进行假设。研究结果指出,SDM和WE之间存在统计学上显著的关系,尽管由于涉及中介变量,这种关系比总体效应弱。两个中介变量(OT和JA)分别增加了整体效果,但它们共同的中介影响主要具有实质性的显著性。研究关系的强度随着工作时间的延长而增加。在员工年龄和农业企业规模的情况下,主要被证明变量的关系存在负向调节效应。

The aim of the paper was to define the effect of the pandemic on employee motivation. Following the questionnaires, the level of motivation in agricultural and forestry organizations before the COVID-19 pandemic in the years 2018–2019 and after the crisis in the years 2020–2021 was defined. The hypotheses were tested using the variance analysis with interactions. The analysed field (financial, social, work, and career-related) was presented by the dependent variable. The categorical independent variables were used to describe the age, gender, and the time before or after the COVID-19 pandemic. A reduction in the level of the requirements in all areas of motivation in terms of age and gender is the result of the study. The needs and requirements of the employees of agricultural and forestry organizations are reduced. The order of importance of the groups stays almost the same. The finding that the impact of the COVID-19 pandemic has, besides others, effect on human resource management, especially on employee motivation, is considered the main contribution of the study. The results of the study result in enhancing the knowledge about economic development through human resource management at the time of the health crisis caused by the COVID-19 pandemic.
本文的目的是确定疫情对员工积极性的影响。根据问卷调查,确定了2018-2019年COVID-19大流行之前和2020-2021年危机之后农业和林业组织的动机水平。使用相互作用的方差分析对假设进行检验。分析的领域(金融、社会、工作和职业相关)由因变量表示。分类自变量用于描述年龄、性别和COVID-19大流行前后的时间。这项研究的结果是,在年龄和性别方面减少了所有动机领域的要求水平。减少了农林组织员工的需求和要求。各组的重要性顺序几乎保持不变。COVID-19大流行的影响,除其他外,对人力资源管理的影响,特别是对员工激励的影响,被认为是该研究的主要贡献。研究结果表明,在COVID-19大流行造成的健康危机时期,通过人力资源管理提高了对经济发展的认识。

The present study aims to investigate the roles of agricultural firms' green dynamic capabilities (DCs) and 'motivation to achieve legitimacy' in the relationship between green intellectual capital (IC) and green innovation. We posit the 'resource-capability-outcome' model according to which green IC is an important strategic resource which helps firms to build and increase green DCs in order to achieve green innovation outcomes. The data were collected from 146 firms operating in both primary and secondary sectors. Partial least squares structural equation modelling (PLS-SEM) was used with WarpPLS 8.0 to process and analyse the data. The results indicated that green DCs serve as an important underlying mechanism and mediate the relationship between green IC and green innovation. Moreover, results also supported the moderating role of the firms' motivation to achieve legitimacy, implying that high motivation strengthens the relationship between green DCs and green innovation. However, the results did not support moderation for the relationship between green IC and green DCs.
本研究旨在探讨农业企业绿色动态能力(dc)和“合法性动机”在绿色智力资本(IC)与绿色创新关系中的作用。我们建立了“资源-能力-结果”模型,该模型认为绿色集成电路是一种重要的战略资源,可以帮助企业建立和增加绿色集成电路以实现绿色创新成果。这些数据是从146家从事第一和第二产业的公司中收集的。采用偏最小二乘结构方程模型(PLS-SEM)对数据进行处理和分析。研究结果表明,绿色创新是绿色集成电路与绿色创新之间的重要中介机制。此外,研究结果还支持了企业实现合法性的动机的调节作用,这意味着高动机加强了绿色发展决策与绿色创新之间的关系。然而,结果不支持绿色IC和绿色dc之间的关系的调节。

Making a Markowitz portfolio with agricultural commodity futures 用农产品期货做马科维茨投资组合
Pub Date : 2022-06-14 DOI: 10.17221/78/2022-agricecon

This paper constructs a minimum-variance portfolio of six agricultural futures. We make a full sample analysis as well as a pre-COVID and COVID examination. Using Markowitz portfolio optimisation, we find that soybean futures have the highest share (31%) in the full sample portfolio because it has the lowest variance. Both soybean oil and rice futures have the second highest weight in the full sample portfolio, in an amount of 24%, because soybean oil has the second lowest variance, whereas rice has, by far, the lowest average correlation with other agricultural futures. Soybean oil has the highest share of 35% in the pre-COVID period, whereas rice follows with 27%. On the other hand, in the COVID period, soybean has a very high share in an amount of 47% due to the lowest risk, while rice takes second place with 19%. Based on the results, investors should invest the most in soybean oil and rice in tranquil periods, while the choice should be soybean and rice in crisis periods. Rice is the choice in both sub-periods because rice has a very low correlation with other agricultural commodities, which happens due to the price stabilisation of rice that is often conducted by Asian countries.
本文构建了6种农产品期货的最小方差组合。我们进行完整的样本分析以及预COVID和COVID检查。使用马科维茨投资组合优化,我们发现大豆期货在整个样本投资组合中的份额最高(31%),因为它具有最低的方差。大豆油和大米期货在整个样本组合中的权重都是第二高的,为24%,因为大豆油的方差是第二低的,而大米与其他农产品期货的平均相关性是最低的。大豆油在疫情前的份额最高,为35%,其次是大米,为27%。另一方面,在新冠疫情期间,大豆因风险最低,所占份额非常高,为47%,其次是大米,占19%。结果表明,在经济平稳时期,投资者应优先投资大豆油和大米,而在经济危机时期,投资者应选择大豆油和大米。大米是这两个子时期的选择,因为大米与其他农产品的相关性非常低,这是由于亚洲国家经常进行大米价格稳定。

Implementation of quality improvements and innovations in agricultural enterprises 实施农业企业质量改进和创新
Pub Date : 2022-06-09 DOI: 10.17221/410/2021-agricecon

This article deals with the implementation of innovations and quality improvements into operations of mainly small and medium-sized enterprises and family farms in the Czech Republic. The aim is to improve the competitiveness of production in internal, European, and global markets, as well as in the context of optimising the settings and recommendations for new subsidies within the Common Agricultural Policy for the forthcoming programming period. The dependence of the use of various forms of innovation in relation to financial crises was investigated, as well as the general (proactive vs. reactive) attitude to innovation, and also mutual operation with Local Action Groups (LAGs) as another source of support. Due to the structure of the obtained data, a general linear model (GLM) was used for the evaluation. Using the methods of advanced statistical testing, the two most important aspects of the implementation of innovations in agriculture enterprises were identified from the obtained data. These two key aspects are: cooperation with the LAG and the use of consultants for processing project applications. Thus, other factors, the size of the farm, the existence of financial problems and the length of farming are not statistically significant. This contribution is intended to help public administration bodies that have a power to set the support conditions for the Rural Development Programme.
本文讨论了在捷克共和国主要是中小型企业和家庭农场的经营中实施创新和质量改进的情况。其目的是提高生产在国内、欧洲和全球市场上的竞争力,以及在即将到来的方案拟订期间优化共同农业政策范围内新的补贴的环境和建议。研究还调查了与金融危机相关的各种创新形式的依赖性,以及对创新的一般(主动vs被动)态度,以及与地方行动小组(lag)作为另一种支持来源的相互合作。由于所得数据的结构,采用一般线性模型(GLM)进行评价。利用先进的统计检验方法,从获得的数据中确定了农业企业实施创新的两个最重要的方面。这两个关键方面是:与援助和援助小组合作和使用顾问处理项目申请。因此,其他因素,农场的规模,是否存在财务问题和农场的长度在统计上不显著。这笔捐款的目的是帮助有权为农村发展方案制定支助条件的公共行政机构。

The role of strategic innovation activities in creating Spanish agriculture companies' innovativeness 战略创新活动在创造西班牙农业公司创新能力中的作用
Pub Date : 2022-06-03 DOI: 10.17221/66/2022-agricecon

The aim of this study is to identify strategic innovation activities that influence the product and process innovativeness of Spanish agriculture companies. From a theoretical perspective, according to the Oslo Manual, strategic innovation activities can be divided into five key groups. Based on a dataset including 874 firms covered by the 2014 edition of the Community Innovation Survey (CIS), we examine the role of different forms of strategic innovation activities used for the introduction of product and process innovations. Using the logit regression model and marginal effects, we found evidence of a relationship between the strategic activities and the product and process innovations in Spanish agriculture companies. The results indicate that only one type of strategic innovation activity, i.e. in-house research and development (R&D) is a common statistically significant factor explaining the product and process innovation. In the case of the other strategic innovation activities, some differences can be found. Thus, external R&D and other activities are significant for product innovation, but not for process innovation. In turn, the acquisition of machinery, equipment, software and buildings and training for innovative activities are significant for process innovation, but not for product innovation.
本研究的目的是确定影响西班牙农业公司产品和工艺创新的战略创新活动。从理论的角度来看,根据《奥斯陆手册》,战略创新活动可以分为五个关键类别。基于2014年社区创新调查(CIS)涵盖的874家公司的数据集,我们研究了不同形式的战略创新活动在引入产品和工艺创新中的作用。利用logit回归模型和边际效应,我们发现了西班牙农业公司战略活动与产品和工艺创新之间存在关系的证据。结果表明,只有一种战略创新活动,即内部研发(R&D)是解释产品和工艺创新的共同统计显著因素。在其他战略创新活动的情况下,可以发现一些差异。因此,外部研发和其他活动对产品创新有重要意义,但对工艺创新没有意义。反过来,机械、设备、软件和建筑物的获取以及创新活动的培训对于过程创新是重要的,但对于产品创新则不是。
