How Contexts Drive Substitution: A Case Study on Alternative Innovation of Key Core Technologies in Private Enterprises

Clarifying the mechanism of context-driven alternative innovation for private enterprises' key core technologies is of great significance for breaking through the "chokepoint" dilemma of key core technologies and realizing self-reliance and self-improvement in science and technology. This study takes Lianchuang Electronic Technology Co., Ltd. as the research object to systematically explore how private enterprises connect technology and market driven by context to achieve domestic substitution. The research findings are as follows: Under the user context drive, private enterprises focus on users' high-pain-point needs, rely on external resources to complete leapfrog alternative innovation, and form an "external-drive-led adaptive coupling"; under the industrial context drive, private enterprises conduct forward-looking layout based on technological advantages, realize coherent alternative innovation through cross-context technology reuse and the construction of an independent innovation chain, and form an "internal-drive-led symbiotic coupling"; under the regional context drive, private enterprises anchor strategic intentions, rely on the regional ecological resource network and real-time feedback of market information, realize circular alternative innovation featured with dynamic mutual feeding between technological iteration and market expansion, and deepen the "internal-drive-led symbiotic coupling mechanism". This study reveals the dynamic matching framework of "context type—alternative innovation type—driving method", and the evolution law of the technology-market coupling mechanism. It fills the gap in the existing research that insufficient attention is paid to the context connection mechanism in the whole process of alternative innovation, and provides a new perspective for the theoretical research and management practice of domestic substitution of key core technologies.
