Feeling hungry? let's order through mobile! examining the fast food mobile commerce in China

This study proposes a unique framework that aids to enrich online shopping experience (psychological and monetary gains) and accelerates fast food mobile commerce (m-commerce). The extended technology acceptance model (TAM) is applied while the stimulus–organism–response (S–O–R) paradigm served as the predominant framework combined with the acquisition-transaction utility theory. This study investigates the mobile website quality, website brand equity (stimulus) influence on (PEOU) and (PU) (organism) to predict Chinese consumer intention to use fast food mobile commerce (response). A total of 936 respondents were participated while data were collected using a convenience sampling technique in China. Results reveal that all dimensions of mobile WQ (i.e., service quality, system quality, and information quality) and Website BE (i.e., brand image, perceived quality, brand association, and brand loyalty) (stimulus) significantly substantially influence PEOU and PU (organism) toward the acceptance of online fast food shopping (response). Digital Coupon Proneness (an accelerator) substantially moderates the relationship between PEOU, PU, and intention to use fast food m-commerce. Based on the assumptions of acquisition-transaction utility theory, category-specific (fast food) digital coupon proneness increase m-commerce for online fast food buying– a novel contribution of the study. Furthermore, research provides unique managerial insights for the industry to utilize the maximum potential of m-commerce in the fast-food industry.

云南省农业科技创新资源配置效率及影响因素研究

[目的]为及时了解云南省农业科技创新的最新动态,充分合理地开发云南省农业科技资源,文章对2002—2016年云南省的农业科技创新资源配置进行研究。[方法]首先分析各个单项指标15年内的变化趋势,分析其对资源配置的影响和作用。再运用DEA模型分析法,将2002—2016年的每个年份作为一个决策单元进行处理,对云南省农业科技创新资源配置效率进行分析。[结果] 2002—2016年云南省农业科技创新资源配置的综合效率为0. 984,并且呈现出不稳定的波动,在2004和2009—2012年出现了配置效率降低的情况。总体来看,资源配置的综合效率大体上是接近于1的水平。处于DEA有效的年份为2002—2003年,2005—2008及2013—2016,属于规模报酬不变的阶段; 2004年属于弱DEA有效阶段,规模报酬则处于上升阶段;处于非DEA有效的有2004年、2009—2012年。[结论]云南省农业科技创新资源的配置效率整体水平处于较高的状态,综合效率值总体上接近于1。有个别年份出现了较小范围的波动,可能与总播种面积的变化有关。综合来看,云南省农业科技创新资源在技术投入、人力资源和农业资金投入逐年的增加,使资源配置效率能够保持在较高的水平,并在出现下降后迅速恢复。

Brand and quality effects on introduction of store brand products

This paper considers a supply chain with a single manufacturer selling a national brand product via a single retailer. The retailer has the option to introduce a product under his own brand into the market with the same functionality as the national brand product. We simultaneously consider the consumer bases of the national brand and store brand along with consumers' willingness to pay for quality and the supply chain control (centralized vs. decentralized). By analyzing the game-theoretic models, we offer managerial insights about the influences of brands' consumer bases on the quality and pricing decisions of the retailer, and on the manufacturer's willingness-to-collaborate when the retailer introduces the store brand product. We find that, although it is usually easier for the retailer to introduce a product under a store brand with a large consumer base, doing so with manufacturers of well established national brands can be difficult, when the retailer often has to greatly mark down his store brand product's quality and price. We also find that a store brand product with a small consumer base shall be launched only when the supply chain is switched to a centralized control and when the manufacturer's national brand has a large consumer base. These important findings offer guidance to both national brand manufacturers and retail store managers regarding the launch of store brand products.     

Economic impacts of smallholder farmers’ adoption of drought-tolerant maize varieties

Drought and high temperatures are major threats to sustainable food production and consequently the livelihoods of the majority of Africans who depend on fragile agricultural systems. As a response to these threats, climate-smart agricultural technologies, such as drought-tolerant maize (DTM) varieties, have been developed and promoted on the continent. It is well-known that the adoption of improved technologies generally impacts positively on the wellbeing of adopters. Nevertheless, the magnitude of the impact of any technology or intervention is always an empirical question. Therefore, this study sought to determine the factors that influence the adoption of DTM and subsequently estimate how yield, commercialization intensity, and farm income are affected by adoption. To establish causation, we relied on observations from 200 farm households in the Northern Region of Ghana and estimated an instrumental variable regression. Consistent with findings reported in the literature, we found that DTM adoption is primarily driven by access to seed, extension service, labor availability, and location of farm households. In addition, we found that DTM adoption positively impacts on yield and commercialization intensity. The magnitude of impact is not trivial. For example, the yield of farm households increased by more than 150% (936 kg/ha) following DTM adoption. These results imply that policy-makers and development practitioners must support research and promotion of climate-smart agriculture to improve adoption and welfare indicators, such as yield and commercialization.     

新零售视角下贵州农资物流配送模式研究

农业是国民经济的基础,而农业生产资料的支持是农业发展的基础。在“三农”问题愈发重要的今天,农业生产资料的配送问题也随之显得十分重要。贵州省农村物流发展缓慢,传统的农资配送过程中存在着配送环节过多、配送成本过高、企业获得利润过少的问题,同时也造成了农民生产成本过高、收入低的现象。文章在分析了贵州省农资物流供应链发展现状、存在问题以及问题产生的原因基础之上,提出了“新零售”视角下建立贵州农资配送新模式。     

黑龙江省农业旅游资源分布及其价值分析

[目的]对黑龙江省农业旅游资源分布及其价值进行分析和评价,以期为黑龙江省农业旅游的可持续发展提供参考和借鉴。[方法]文章对黑龙江省农业旅游资源进行分类型论述,采用层次分析法(AHP)建立黑龙江省农业旅游资源价值评价体系,根据农业旅游经营者和管理者对指标的打分值与指标权重值加权计算各类型农业资源价值指数并分析资源价值。[结果](1)根据农业资源分布、地理环境、气候天象、人文特色,将黑龙江省农业旅游资源划分为地文农业旅游区、水文农业旅游区、气候天象农业旅游区、生物生态农业旅游区、人文农业旅游区5个区域,各区域各有特色,差异性明显。(2)根据各区域资源价值指数分析看出,气候天象农业旅游区的资源价值最大,其次是地文农业旅游区,然后是水文农业旅游区和生物生态农业旅游区,人文农业旅游区的资源价值最小。[结论]黑龙江省农业旅游资源非常丰富,能够形成一个相对完整的农业旅游资源体系,具有较强的可持续发展潜力。在黑龙江省农业旅游的五大发展区域中,气候天象农业旅游区和地文农业旅游区的旅游资源价值较大。黑龙江省可以持续开发建设这一类农业旅游项目,并根据季节性与地理环境特征着力打造冰雪农业旅游。     

农机补贴的收入分配效应：效率、公平，抑或兼而有之*

农机补贴是具有门槛效应的效率增益政策，通常效率与公平如鱼和熊掌不可兼得。本文通过理论模型分析了农机补贴对农业生产及农村劳动力转移的影响；并通过工具变量法和中介变量法研究了农机补贴的收入分配效应及其作用机制。研究发现，农机补贴显著降低了农户收入的基尼系数，提高了收入分配公平性；其作用机制是农机补贴提升了农业生产效率，促进了农村劳动力转移，提高了打工收入，尤其是相对贫困农户，溢出效应对冲了门槛效应，使得农机补贴的收入分配效应兼具了效率和公平。     

Land pressures,the evolution of farming systems,and development strategies in Africa: A synthesis

Evidence assembled in this special issue of Food Policy shows that rising rural population densities in parts of Africa are profoundly affecting farming systems and the region’s economies in ways that are underappreciated in current discourse on African development issues. This study synthesizes how people, markets and governments are responding to rising land pressures in Africa, drawing on key findings from the various contributions in this special issue. The papers herein revisit the issue of Boserupian agricultural intensification as an important response to land constraints, but they also go further than Boserup and her followers to explore broader responses to land constraints, including non-farm diversification, migration, and reduced fertility rates. Agricultural and rural development strategies in the region will need to more fully anticipate the implications of Africa’s rapidly changing land and demographic situation, and the immense challenges that mounting land pressures pose in the context of current evidence of unsustainable agricultural intensification, a rapidly rising labor force associated with the region’s current demographic conditions, and limited nonfarm job creation. These challenges are manageable but will require explicit policy actions to address the unique development challenges in densely populated rural areas.
