Agglomeration Effects in Ontario's Dairy Farming
研究了奶牛场密度对生产效率的正向影响，使用随机投入距离函数和异方差无效率模型，发现安大略省奶牛场集聚显著提升了生产效率，对理解农业企业选址和农民保护农业活动有启示。
Abstract This paper examines the agglomeration hypothesis, which states that a firm's productive efficiency is increased by closer proximity to other firms. Using a stochastic input distant function with heteroskedastic inefficiency effects, we find that the density of Ontario dairy farms has a significant positive economic effect on production efficiency. The finding has implications for understanding agricultural firm location and farmer‐led efforts to preserve agricultural farming activities in specific locations.
