摘要｜Abstract
本文考虑了具有规模效应的冲突网络模型。我们刻画了其中唯一的均衡，并且分析了参与者的均衡行为。我们发现，当两个联盟的规模差别较大时，规模效应与（个人和全部）均衡努力之间存在倒U型关系。这一发现表明，从降低冲突强度的角度上，规模效应的增加可能是有益的。
This paper considers a conflict network model with returns to scale technology. We characterize the unique equilibrium and analyze the equilibrium behaviors of agents. In particular, we show that there exists an inverted U relationship between the returns to scale technology and (individual and total) equilibrium efforts, when two coalitions are sufficiently different in size. This finding suggests that an increase in returns to scale technology can be beneficial in the sense that it reduces conflict intensity.
