以关键核心技术突破牵引现代化产业体系构建是现代化强国建设的必然选择。本文基于网络嵌入性和耦合理论，以航天科技集团及其历史沿革机构为例，探究企业关键核心技术突破牵引现代化产业体系构建的具体过程和内在机制。研究发现:（1）关键核心技术突破通过触发企业内外部网络嵌入、实施资源行动、调整网络耦合关系来推动现代化产业体系构建，阶段性地表现为系统集成突破、系统架构蝶变和体系融合创新；（2）随着关键核心技术从系统层面到体系层面的突破升级，企业依次采取“构建-适配-共振”的双重网络策略，在“连通型-中介型-架构型”网络嵌入下，阶段性实施资源集聚、巧用和共生行动，进而促进内外部网络耦合关系实现从“主导-响应”型、“探索-适配”型向“策源-共振”型的转变；（3）现代化产业体系呈现出“根基型-迭代型-生态型”的演化规律，其中未来、新兴、传统产业发生阶梯式转化，完整性、安全性和先进性三种核心特征相互依存、协同跃升。研究揭示了以关键核心技术突破牵引现代化产业体系构建的理论黑箱，为加快现代化产业体系建设提供实践启示。

Taking breakthroughs in key core technologies to drive the construction of a modern industrial system is an inevitable choice for building a great modern socialist country. Based on network embeddedness theory and coupling theory，this study took China Aerospace Science and Technology Corporation （CASC） and its historically evolved institutions as research objects，and explored the specific process and internal mechanism of how enterprises' breakthroughs in core key technologies drive the construction of a modern industrial system. The findings are as follows:（1） Breakthroughs in key core technologies promote the construction of a modern industrial system by triggering internal and external network embedding，implementing resource actions，and adjusting network coupling relationships，which are phasedly manifested as system integration breakthroughs，system architecture transformation，and system integration and innovation. （2） With the upgrading of key core technology breakthroughs，enterprises sequentially adopt the action strategies of "construction-adaptation-resonance" for internal and external networks. Under the network embedding actions of "connected-intermediary-architectural" types，it implements resource aggregation，leveraging，and symbiosis actions in stages，thereby promoting the transformation of the internal and external network coupling relationship from the "dominant-response" type and the "exploration-adaptation" type to the "origination-resonance" type. （3） The modern industrial system presents an evolutionary law of "foundation-iteration-ecology"，in which future industries，emerging industries，and traditional industries undergo stepped transformation，while the three core characteristics of integrity，security，and advancement are interdependent and achieve coordinated upgrading. This study reveals the theoretical black box of constructing a modern industrial system driven by key core technologies，and will provide certain theoretical basis for accelerating the construction of a modern industrial system.
