摘要

我们提供了探索性的见解,探讨那些管理强劲和成功增长的农场如何通过土地的空间竞争影响其社区的农场。这项研究是基于对商业游戏《FarmAgriPoliS》中重复框架实验的探索性分析。Balmann,生态复杂性,40,2019)。特别地,我们分析了农场管理者不同行为集群的空间影响。我们的分析发现,那些增长强劲的农场在很大程度上影响了大约10公里空间范围内农场的发展。虽然对邻近地区的影响随着距离的增加而减小,但农场增长和出口的函数相关性既不是线性的,也不是指数的,而是最终呈波浪状的。在此基础上,进一步探讨了农场的空间相互依赖以及捕食现象与农场路径依赖和农业结构变化的相关重叠。我们的结论是,除了农民的策略和能力之外,他们邻居的特征和邻近农场之间的距离也决定了谁是“捕食者”,谁是“猎物”。

Predator or prey? Effects of farm growth on neighbouring farms

We provide explorative insights on how farms which manage strong and successful growth affect farms in their neighbourhoods through spatial competition for land. The study is based on an exploratory analysis of repeated framed experiments within the business game FarmAgriPoliS (Appel & Balmann, Ecological Complexity, 40, 2019). In particular, we analyse the spatial influences of different behavioural clusters of farm managers. Our analysis finds that farms which manage strong growth substantially affect the development of farms in a spatial neighbourhood of some 10 km. Although the influence on the neighbourhood decreases with distance, the functional correlations of farm growth as well as exits are neither linear nor exponential, but eventually rather wave-like. We further discuss the spatial interdependence of farms and the related overlaps of the predator–prey phenomenon with the phenomena of farms' path dependency and agricultural structural change. We conclude that along with farmers' strategies and their abilities, the characteristics of their neighbours and the distances between neighbouring farms also determine who is ‘predator’ and who is ‘prey’.

期刊介绍: Published on behalf of the Agricultural Economics Society, the Journal of Agricultural Economics is a leading international professional journal, providing a forum for research into agricultural economics and related disciplines such as statistics, marketing, business management, politics, history and sociology, and their application to issues in the agricultural, food, and related industries; rural communities, and the environment. Each issue of the JAE contains articles, notes and book reviews as well as information relating to the Agricultural Economics Society. Published 3 times a year, it is received by members and institutional subscribers in 69 countries. With contributions from leading international scholars, the JAE is a leading citation for agricultural economics and policy. Published articles either deal with new developments in research and methods of analysis, or apply existing methods and techniques to new problems and situations which are of general interest to the Journal’s international readership.
