Collaborative Innovation Strategy of Supply Chain in the Context of MCU Domestic Substitution : A Differential Game Analysis

Abstract

The domestic substitution of the IC (the Integrated Circuit) industry improves economic efficiency and is significant in ensuring national security, which has gradually become an essential strategy for countries worldwide. Based on the background of domestic substitution of integrated circuits, we select a typical component Micro Controller Unit) as the research object, construct a three-level supply chain game model under different scenarios in a dynamic architecture, and analyze the game problem of collaborative innovation of the MCU supply chain. We fully consider the impact of factors such as time, cost and the innovation and collaborative innovation efforts of various supply chain members on the level of domestic substitution. Moreover, we put forward a two-part pricing + cost-sharing contract to achieve supply chain coordination. We found that: (1) Collaborative innovation of the supply chain in the centralized decision-making scenario achieves the highest level, followed by the cost-sharing scenario; (2) The two-part pricing + cost-sharing contract can help achieve supply chain coordination; (3) The trend of the MCU domestic substitution level with manufacturing cost is U-shaped, which means the increase of manufacturing cost may have a positive impact on the process of domestic substitution.

Digital technology adoption strategies for a contract farming supply chain under CVaR criterion

“…In this case, the farmer adopts digital technology to plant agricultural products and the cost of digital investment is shared by the farmer and the platform, that is, the cost‐sharing contract is reached between the platform and the farmer. Cost‐sharing contracts are very common in practice (Shan et al, 2021; Wang et al, 2023). The cost‐sharing ratio of the platform is , and the remaining is borne by the farmer.…”

Resilience evaluation of low-carbon supply chain based on improved matter-element extension model

“…A learning organization is one in which an enterprise or organization can learn from experience, strengthen communication between organizations, share knowledge and culture between organizations, and make up for shortcomings after experiencing supply chain disruptions [ 51 ]. Collaborative innovation means that enterprises in the supply chain can find partners, integrate their resources and technologies, and realize collaborative technology innovation and management innovation [ 52 ]. Product development refers to the time and cost required by a company to develop a new product after it has an insight into a business opportunity [ 53 ].…”
