Agricultural land demand tends to be in weak condition vis-à-vis settlement development, transport infrastructure and industry expansion. At the same time, the awareness and demand of consumers for regional food is constantly rising, in particular in urban regions. The resulting challenge is that high demand for regional food is concentrated at places where land for food production tends to be particularly under pressure. Against this background, our article reflects on the extent to which regional food supply chains support the status of agricultural demand in the competition for land. The main aim of our paper is to understand the role of proximity between the different stages of value creation, including cultivation, production (manual or industrial) and trade (retail, direct marketing). Our empirical study on the example of three products in Bavaria (Germany) shows that short distances within food value chains support the agricultural condition in land use dynamics (beer, sweet cherry, asparagus). The analyses are based on official and internal statistics as well as expert interviewing. This mixed-methods approach results in value-creation mappings and provides spatial differentiation of the economic process. Proximity between at least two stages of value creation plays an important role to explain the economic trends and land use dynamic. These findings are rooted in arguments of efficiency, tacit knowledge, networks, as well as product reputation. However, the role of proximity does not automatically play a role but has to be stabilized by strategic measures such as product innovation and marketing measures.

食品生产中的短价值链：空间邻近性对经济和土地利用动态的作用

相对于定居点开发、交通基础设施和工业扩张，农业用地需求往往处于疲软状态。与此同时，消费者对区域食品的意识和需求也在不断提高，尤其是在城市地区。由此产生的挑战是，对区域粮食的高需求集中在粮食生产用地往往压力特别大的地方。在此背景下，我们的文章反映了区域食品供应链在多大程度上支持农业需求在土地竞争中的地位。我们论文的主要目的是了解价值创造的不同阶段之间的邻近性，包括种植、生产（手工或工业）和贸易（零售、直销）。我们对巴伐利亚（德国）三种产品的实证研究表明，食物价值链内的短距离支持土地利用动态（啤酒、甜樱桃、芦笋）的农业条件。分析基于官方和内部统计数据以及专家访谈。这种混合方法导致价值创造映射，并提供经济过程的空间差异。价值创造的至少两个阶段之间的接近度在解释经济趋势和土地利用动态方面起着重要作用。这些发现植根于效率、隐性知识、网络以及产品声誉的争论。然而，邻近的作用不会自动发挥作用，而是必须通过产品创新和营销措施等战略措施来稳定。
