摘要:

高端装备制造极易遭受技术封锁、贸易制裁、地缘冲突等风险多源叠加和多重传递的影响,导致企业运营失稳失效。识别多源风险传递的关键节点和关键路径,是高端装备制造企业高效防控风险的前提。为此,本文探讨高端装备制造多源风险传递网络构建、多源风险传递关键节点及关键路径挖掘方法。首先,结合短语抽取、BERTopic、语义分析、情感分析等技术,识别多源风险因子及其关联关系,量化风险因子自身风险强度和风险因子间传递风险强度,构建多源风险传递网络;其次,利用加权接近中心性量化风险因子在网络中传递风险强度,结合风险因子自身风险强度,挖掘多源风险传递关键节点;最后,基于Choquet Fuzzy积分非线性叠加多源风险,采用蚁群算法挖掘多源风险传递关键路径。本文方法突破传统单源风险分析方法的局限,智能构建多源风险非线性叠加下高端装备制造风险传递网络,量化风险因子在网络中的重要度,测度风险多源叠加多重传递下路径风险水平,挖掘多源风险传递关键节点和关键路径,为企业精准防控多源风险提供科学依据。

Abstract:

High-end equipment is characterized by high technological complexity and significant reliance on critical external components, making enterprises in this sector particularly vulnerable to multi-source risks such as technological blockades, trade sanctions, and geopolitical conflicts in unstable and uncertain environments. These risks often overlap, propagate, and amplify, leading to cascading disruptions, operational instability, and substantial losses. Constructing multi-source risk transmission networks and identifying critical nodes and paths within these networks is essential for effectively preventing and mitigating risks in high-end equipment manufacturing.In this study, a systematic methodology is developed to construct multi-source risk transmission networks and identify critical nodes and paths. Potential risk factors are identified using phrase extraction techniques combined with the BERTopic model. Semantic association rules between risk factors are defined, and their associations are determined using a sliding window similarity method, which facilitated the construction of a multi-source risk factor association network. The intrinsic risk strength of each risk factor, as well as the transmission strength between factors, is quantified to transform the association network into a multi-source risk transmission network. Weighted closeness centrality is employed to measure the transmission strength of risk factors in the network, and critical nodes are identified by integrating their intrinsic risk strength with transmission potential. Finally, the Choquet fuzzy integral is applied to non-linearly aggregate multi-source risks, and an ant colony algorithm is exploited to determine critical transmission paths within the network.Risk texts are collected through a mixed-method approach: online texts are crawled from prospectuses and annual reports of listed high-end equipment manufacturers, while offline texts are gathered through on-site interviews with managers and employees at a CRRC subsidiary to supplement operational risk-related narratives.Key findings include 1) Identification of 91 risk factors and their associations, forming a multi-source risk factor association network; 2) Derivation of 28 two-source concurrent risk scenarios from eight primary risk sources, leading to the construction of 28 two-source risk transmission networks; 3) Frequent identification of critical risk factors such as insufficient production capacity, rising production costs, and declining market demand in two-source risk transmission networks, alongside other critical factors like damaged production equipment, reduced industrial investment, and reliance on imported raw materials; 4) Observation that two-source risks tend to converge and amplify at critical factors such as insufficient production capacity, rising production costs, and declining market demand; 5) The most detrimental critical paths emerged from the concurrent occurrence of public health emergencies and macroeconomic downturns, causing peak-level risks and severe operational damage to enterprises.

Key words: high-end equipment manufacturing, multi-source risk transmission networks, critical nodes, critical paths
