Against the backdrop of profound restructuring of the global sci−tech industrial landscape, this study addresses the lack of systematic review of China's sci−tech industrial innovation development and the insufficient holistic analytical framework for its key breakthroughs and leading advantages. Taking the development course of China's sci−tech industry since the reform and opening−up as the main line, combined with Lu Yongxiang's theoretical discussions on scientific and technological innovation and the development of new quality productive forces, this paper systematically sorts out major innovation achievements in fields such as energy and power, quantum information, artificial intelligence, aerospace engineering, transportation infrastructure, advanced manufacturing, and national defense technology over the past two decades. It analyzes key driving factors including policy support, talent development, and industrial transformation, and reveals China's innovation development path and evolution law from following imitation to running neck and neck with global leaders and taking the lead. The study shows that China has achieved technological breakthroughs and taken the lead in industries such as renewable energy, high−speed rail networks, aerospace engineering, quantum computing, and the digital economy, forming a full−chain innovation model covering basic research, technological innovation, and large−scale industrialization. The large−scale development of green energy, high−end equipment, and new materials industries has become a core driving force for the development of new quality productive forces. The review and analysis in this study can provide reference and support for the formulation of China's sci−tech industrial development strategies, optimization of the innovation ecosystem, and layout of future cutting−edge technologies.
