从消费者偏好的视角,探究加工农产品的附加值来源,能够为中国农产品加工业发展提供关键信息。以果汁产品为例,本文采用选择实验法实证分析了消费者对产品类型、品牌地、加工地、原料产地和转基因等产品属性的偏好与支付意愿。研究结果表明,产品类型和非转基因是果汁产品附加值提升的关键,品牌和原料的原产国也有助于实现加工农产品的附加值;消费偏好具有显著的异质性特征,针对不同消费群体的产品质量设计有助于实现加工农产品的附加值。因此,政府产业政策部门和农产品加工企业可以通过调整产品类型和加贴非转基因标签,来提升中国加工农产品的附加值。同时,通过政府或行业协会实施品牌和原料的原产国公共推广政策、维护和塑造原产地正面形象,也能够有效提升附加值。 相似文献

This article investigates 4 key areas of supply chain management to identify opportunities to create value for Australian farmed barramundi. These key areas are product attributes, material flow, information flow, and relationships. This exploratory study forms the first stage of a value chain mapping study. Based on data gathered from 13 in-depth interviews, 7 with farmers and 6 with wholesalers/retailers, a preliminary map of the value chain for Australian farmed barramundi was developed. From a producer perspective, 3 key issues emerged: lack of collaboration, inconsistency of product quality, and lack of knowledge of what consumers value. Although wholesalers/retailers identify product consistency as a key issue, they further identify product dumping and the growth of imports as areas of major concern. These findings laid the foundation for strategy development at both the individual and industry level. The insights from this case highlight the value of chain analyses as a diagnostic tool for strategy development. 相似文献

Climate induced events exacerbate food production and distribution risks, posing a threat to global food security. Though many studies focus on farmer adaptation to climate change, there are few studies of actors in the middle of agricultural value chains such as traders, logistics providers, and processors. The activities of these actors, referred to as the ‘hidden middle’, are key determinants of the prices received by farmers and the price and quality of food products for consumers. We explore how climate events and risk perceptions affect the adoption of value‐adding and damage control strategies among maize traders in Nigeria, Africa’s largest economy and most populous country. We find consistent evidence that climate events and climate risk perception discourage the adoption of value‐adding practices including storage. This potentially affects the availability and price of maize for consumers (household and industry) in the lean season. However, once traders store maize, climate risk does not affect the adoption of damage control, but training and social networks do. These findings suggest that actors in the midstream of food value chains are responding to climate change and more attention needs to be paid to these actors to maintain the availability of affordable and safe maize products throughout the year. There is also a need for strategies to reduce the risks of trading activities due to climate change. 相似文献

The Interaction of Global Value Chains and Rural Livelihoods: The Case of Smallholder Raspberry Growers in Chile 总被引:1,自引:0,他引:1
This paper integrates aspects of global value chain and sustainable rural livelihoods analyses in an exploration of the local impacts of agri‐food globalization in Chile. In particular, it examines the evolution of the raspberry export sector in the context of Chile's non‐traditional agricultural export boom, and considers its importance to smallholder growers and rural households in central Chile. The paper first outlines the geography and structural configuration of the global value chain for Chilean raspberries, and considers modes of governance and forms of coordination between key actors within the chain. Second, the terms and implications of smallholder grower participation in the value chain are explored in a discussion of access to key livelihoods assets. The paper concludes that institutional support to smallholders, even in the case of a crop that is widely seen to have a small‐scale ‘size bias’, remains integral to their capacity to comply with required safety and quality standards and gain and retain market access via the value chain. 相似文献
