摘要翻译：
本文对Kikuchi等人提出的生产链模型进行了扩展和改进。（2018年）。利用单调凹算子理论，证明了均衡价格的存在唯一性和全局稳定性，从而改进了具有多个上游伙伴的生产网络的结果。我们提出了一种计算均衡价格函数的算法，它比连续计算算子的速度快十倍以上。然后，该模型被推广到一个随机环境，为生产网络中的企业分布提供了更丰富的含义。

英文摘要：
  In this paper, we extend and improve the production chain model introduced by Kikuchi et al. (2018). Utilizing the theory of monotone concave operators, we prove the existence, uniqueness, and global stability of equilibrium price, hence improving their results on production networks with multiple upstream partners. We propose an algorithm for computing the equilibrium price function that is more than ten times faster than successive evaluations of the operator. The model is then generalized to a stochastic setting that offers richer implications for the distribution of firms in a production network.
