**Introduction** China’s industrial policy has driven leadership in key industries by aligning long-term planning, large-scale investment, state-directed finance, and ecosystem coordination. This approach translated into measurable outcomes: dominant global market shares, rapid cost declines, and accelerated upgrading into higher-value manufacturing sectors. Together, these effects reshaped global competition across clean energy, manufacturing, and technology-intensive industries. **China’s industrial policy model** China’s industrial policy intensified after the 2008 global financial crisis, as policymakers sought to move beyond export- and investment-led growth toward technological upgrading and supply-chain control. Industrial policy instruments include national development plans, preferential finance, infrastructure investment, and regulatory coordination across central and local governments. In recent years, these tools have increasingly been embedded within a techno-nationalist framework that treats industrial capacity as a strategic asset linked to economic security and geopolitical resilience[1][2]. **Drivers of China’s industrial leadership** **1.** **Targeted scale-building created dominant positions in specific value chains** Sustained prioritization of selected industries has resulted in exceptional global scale. By the early 2020s, China accounted for over 30% of global manufacturing value added, exceeding the combined output of several advanced industrial economies[3]. China achieved at least 80% global market share across polysilicon, wafers, cells, and modules in the solar photovoltaic (PV) supply chain[4]. In electric vehicle (EV) value chains, China accounted for over 80% of global EV battery production capacity in 2023, equivalent to roughly 1,783 GWh, far exceeding other regions[5]. **2.** **High investment intensity and state-linked finance accelerated capacity and learning** China’s industrial expansion has been supported by exceptionally high investment intensity. Annual investment has consistently exceeded 40% of gross domestic product, far above levels observed in most advanced economies[6]. This enabled rapid build-out of manufacturing capacity and infrastructure, allowing firms to move quickly down cost curves in industries where scale and learning-by-doing are decisive. **3.** **Ecosystem coordination and upgrading increased the technology content of output** Industrial policy emphasized dense production ecosystems rather than isolated firm support, integrating suppliers, manufacturers, logistics, and research capacity. This coordination shortened innovation cycles and strengthened manufacturing depth[7]. A structural shift accompanied this process: the share of medium- and high-technology manufacturing in China’s total manufacturing output surpassed 40% by the early 2020s[6]. In clean energy, global prices adjusted accordingly, with solar PV module prices declining by more than 80% between 2010 and 2023, consistent with scale-driven learning and manufacturing integration[7]. **Conclusion** China’s leadership in key industries reflects the interaction of strategic targeting, exceptionally high investment, and ecosystem-style coordination that enables rapid scaling and upgrading. These mechanisms produced measurable dominance in selected value chains, sustained global cost declines, and a rising technology content of manufacturing output. Together, they illustrate how industrial policy can reshape global industrial structures and intensify competitive and policy responses elsewhere.
