Many experts agree that more agricultural investment is needed in the global South to improve local food security and reduce poverty. However, there is a lack of consensus about the types of investment needed to achieve these goals. This paper contributes to the literature on large agricultural investments and corresponding business models by inventorying and analysing such investments in Kenya’s Nanyuki area. We identify four clusters of business models that differ primarily by type of production and other distinct determinants, namely: demand from markets; access to land; land tenure regime and colonial history; actors involved; biophysical context; labour availability; and governance of the value chain via private standards. The study results shed light on the factors that help or hinder implementation of large agricultural investments and shape their impacts in the context of African land use systems. The way land is accessed represents one of the most-decisive factors determining the risks and opportunities associated with such projects. We find that most investments in the Nanyuki area occur on land bought or leased from private owners.  相似文献

国内科研人员激励研究范围与热点分析   总被引:1,自引:0,他引:1  
随着我国科技体制改革的深入,科研人员激励问题成为社会和学术的焦点。通过对收集的文献分析,发现国内科研人员激励研究的范围与内容主要存在几个方面:一是收入分配与科研人员激励研究;二是科研人员评价研究;三是科研人员激励宏观政策研究;四是科研人员激励机制研究;五是不同类型组织中的科研人员激励研究景,这五个研究热点构成了国内科研人员激励的研究范围。这些热点不是孤立的,而是相互交叉,在研究中应侧重于系统视角。  相似文献

Researchers have noted the utility of the Investment Model in explaining the formation of loyalty. This study extends the Investment Model in a leisure service context by including two additional constructs of quality and value. Quality and value are proposed as antecedents of satisfaction, with their effects on loyalty mediated by satisfaction. Results from an online panel survey of American cruise passengers support these hypotheses. The study provides a model of loyalty building that may shed new insight on loyalty research.  相似文献

The COVID-19 pandemic has hit the tourism and hospitality sector hard. Hotel managers face uncertainty in this environment in order to survive. This study explores the impact of COVID-19 on the hospitality industry, particularly hotels in Indonesia, one of the largest developing countries. It examines the challenges faced by hotel managers and the strategies used to survive. Through the lens of complexity theory, we discuss whether the strategies being deployed are beneficial, redundant, or detrimental for hospitality businesses. Based on semi-structured interviews with 13 hotel managers in Jakarta, Bandung, and Bali, the findings shed light on the various challenges to hotels. We also highlight which challenges could turn into opportunities. The findings show that the strategies that managers are deploying could be detrimental in the future. Potential future research directions are also discussed.  相似文献

When price-cap rules determine the structure of prices for a long period, they suffer a credibility problem and introduce an element of risk especially if a firm’s profits are “too large”. Profit sharing may be seen as a device to pre-determine price adjustments and thus to decrease regulatory risk. We analyse the effects of profit sharing on the incentives to invest, using a real option approach. Absent credibility issues, a well designed profit sharing system may be neutral relative to a pure price cap. With regulatory risk, profit sharing is preferable to a pure price-cap one, if it intervenes for high enough profit levels.

Rental markets for cultivated land and agricultural investments in China   总被引:1,自引:0,他引:1  
The purpose of this paper is to empirically track the progress and consequences of the emergence of cultivated land markets in China since 2000. We draw on a set of nationwide, household‐level panel data (for 2000 and 2008) and find that the markets for cultivated land rental have emerged robustly. According to our data, 19 of China's cultivated land was rented in farm operators in 2008. We also find that the nature of China's cultivated land rental contracts has become more formal and lengthened the period of time that the tenant is able to cultivate the rented‐in plots. While there may be benefits for lessors and tenants, our data show that there are falling rates of investment in organic manure. The farmers in our sample have reduced organic manure use from 13 tons/ha in 2000 to 5 tons/ha in 2008. Part of this fall is due to the rise of cultivated land rental markets. The analysis, however, does not find that improved property rights in cultivated land rental affect investment largely because property rights have largely been established by 2000, the first year of our sample. Our results, however, also show that there are forces that appear to be mitigating the negative consequences of rising cultivated land rental. After holding constant initial rental rates and other factors, we find that the gap between investment in organic manure in own land and rented‐in land is narrowing. One interpretation of our findings is that if policymakers can find ways to even further strengthen the rights of lessors and tenants as well as lengthen contract periods, farmers—even those that rent—will invest more in their land, because they will be able to capture the returns to their investments.  相似文献

民营企业集群已成为浙江省区域经济快速发展的主流模式之一。与大型企业、跨国公司一起,已成为参与市场竞争的主角。因此,市场营销理论应用领域已从单个企业营销逐步延伸到民营企业集群式营销。民营企业集群式营销是民营企业集群成长的关键,浙江省民营企业集群的快速发展与其营销管理创新是分不开的。为了提高浙江省民营企业集群营销管理水平,本文着重探讨了浙江省民营企业集群营销战略、策略制定及组织实施问题。  相似文献

有效制度供给不足是造成生态环境问题,引发循环经济的诱因,因此,进行制度创新是发展循环经济的基础和保障;在循环经济的制度创新中,政府应该承担起创新的主体。而在我国,在循环经济的制度创新方式上,应该采用渐变性和激变性相结合的创新方式,在循环经济的制度创新内容应重点对循环经济的法律制度、激励制度、产权制度等进行创新。  相似文献

借鉴国内外有关行为财务理论及实证研究成果,笔者以安徽省近年来实力较强的500家民营企业的投融资行为作为研究样本,着重从民营企业管理者"过度自信"心理方面入手,用实证研究的方法探索民营企业在进行投融资决策时所受到的非理性因素干扰的情况。通过本课题的研究,希望在一定程度上解决民营企业投融资行为"实际是什么"的问题,从而使我国的民营企业能够从发展历程中汲取经验和教训,在投融资决策中克服盲目和冲动情绪,努力减少由于非理性因素的干扰而导致的盲目融资和过度投资的行为,尽量避免或减少投资失败和财务困境。  相似文献
