数字赋能的阈值效应与价值循环机制——基于平台与中小制造企业的动态协同研究
The Threshold Effect and Value Cycle Mechanism of Digital Empowerment—A Dynamic Synergy Study Based on Platform and Small and Medium-Sized Manufacturer

近年来，平台企业纷纷开始凭借其在数智化领域的优势赋能传统中小制造企业，这极大地影响了供应链成员的运营决策和收益。本文考察了由平台型企业和一个中小制造企业构成的供应链系统，基于Stackelberg博弈理论设计了两个供应链决策模型，包括平台企业提供普通服务和平台企业提供数字赋能服务。通过分析比较不同情景下的均衡结果，了解了中小制造企业接受平台数字赋能的条件，探讨了市场需求对数字赋能的敏感系数对供应链成员决策及利润的影响机制。研究结果表明：(1) 只有当市场需求对平台数字赋能水平较高时，中小制造企业才会选择使用平台企业的数字赋能服务；(2) 平台企业对中小制造企业的数字赋能可以促进中小制造企业加大数字化投入，从而提高供应链的数字化水平。
In recent years, platform enterprises have begun to empower traditional small and medium-sized manufacturing enterprises with their advantages in the field of digital intelligence, which greatly affects the operational decisions and revenues of supply chain members. This paper examines a supply chain system consisting of a platform-based enterprise and a small and medium-sized manufacturer enterprise, and designs two supply chain decision models based on the Stackelberg game theory, including the platform-based enterprise providing ordinary services and the platform-based enterprise providing digital empowerment services. By analyzing and comparing the equilibrium results under different scenarios, the conditions for small and medium-sized manufacturers to accept the platform’s digital empowerment are understood, and the mechanism of the influence of the sensitivity coefficients of the market demand to the digital empowerment on the supply chain members’ decision-making and profits is explored. The results of the study show that: (1) SMEs will choose to use the platform’s digital empowerment services only when the market demand for the platform’s digital empowerment is high; (2) The platform’s digital empowerment of SMEs can promote SMEs to increase digitalization inputs, thus improving the digitalization level of the supply chain.
