摘要

我们提出了一种基于生态效率的新方法来评估技术采用对农场层面的影响，同时考虑到二次效应。次生效应被定义为对可能影响环境、社会或经济结果的技术的结构和行为适应。我们将该程序应用于挪威的自动挤奶系统(AMS)，发现AMS会产生二次效应，最强烈的是减少每头奶牛的劳动和增加畜群规模。为了估计AMS的效果，我们采用了一种新的因果机器学习方法。AMS对生态效率产生异质性影响，与畜群规模和每头牛的劳动量负相关。

Evaluating environmental effects of adopting automatic milking systems on Norwegian dairy farms

We present a novel procedure based on eco-efficiency for assessing farm-level effects of technology adoption while considering secondary effects. Secondary effects are defined as structural and behavioural adaptations to technology that may impact environmental, social or economic outcomes. We apply the procedure to automatic milking systems (AMS) in Norway and find that AMS induces secondary effects, most strongly by decreasing labour per cow and increasing herd sizes. For estimating effects of AMS we employ a novel causal machine learning approach. AMS induce heterogenous effects on eco-efficiency, negatively associated with herd expansion and labour per cow.

期刊介绍： The European Review of Agricultural Economics serves as a forum for innovative theoretical and applied agricultural economics research. The ERAE strives for balanced coverage of economic issues within the broad subject matter of agricultural and food production, consumption and trade, rural development, and resource use and conservation. Topics of specific interest include multiple roles of agriculture; trade and development; industrial organisation of the food sector; institutional dynamics; consumer behaviour; sustainable resource use; bioenergy; agricultural, agri-environmental and rural policy; specific European issues. Methodological articles are welcome. All published papers are at least double peer reviewed and must show originality and innovation. The ERAE also publishes book reviews.
