Excessive production capacity stands as one fallout of China’s trade strategy leaning heavily toward commercial gain. Such troubles stem from its unique policy framework, which sustains sluggish domestic consumption while steadily expanding industrial production scale. The incoming US administration needs to identify bilateral economic areas requiring limits out of national and economic security considerations. Meanwhile, Washington ought to rebuild an effective global trade order adaptable to an export powerhouse that adopts trade-protective stances and acts as a geopolitical rival.

Complete trade decoupling is impractical and unfavorable given China’s extensive commercial ties with America and other nations. A standardized risk assessment mechanism can help form a new balanced trade state, curbing major hidden dangers while keeping low-risk commodity exchanges intact. Progress in this regard will also lay solid groundwork for revamping global trade norms. Industrial surplus adds to multiple frictions in bilateral commerce, reflecting worries over China’s trade practices. This analysis looks into the roots of redundant production and divergent surplus conditions across the green tech field. Import risks differ amid varied industrial segments. It puts forward a risk-guided standard to formulate targeted policies against surplus-driven challenges. The US is also expected to take the lead in updating multilateral trade rules suitable for current global patterns.

Redundant industrial output shipped overseas undermines American manufacturing and employment. US finance chief Janet Yellen brought up this matter during her 2024 spring visit, mainly pointing out surplus electric vehicle output. Solar and steel production gluts have long remained persistent concerns for the US side. Despite widespread policy discussions surrounding industrial overcapacity, the concept lacks standardized definition in mainstream economic theory and official WTO regulatory frameworks. In simple terms, it refers to excess industrial output that far exceeds domestic consumption needs. When domestic markets cannot fully absorb national production, subsidized domestic goods flood global export markets. Weak internal demand is therefore an inherent feature of such surplus conditions. Industrial capacity utilization rates serve as another key judging benchmark, though these figures fluctuate across sectors and business cycles. An 80% utilization level is generally regarded as the industry standard for healthy operation. For instance, electric vehicle factories maintain high utilization rates, while traditional fuel vehicle production sits below 50%, representing severe underutilization.

China’s ballooning trade surplus reflects both widespread industrial surplus and the core traits of its economic model, which prioritizes export-oriented growth through curbing domestic consumption and offering industrial subsidies. IMF data shows China’s current trade surplus relative to global GDP has exceeded its historic peak recorded in 2008–2009. Even after Washington imposed punitive tariffs on Chinese goods, the bilateral trade gap continues to widen. This demonstrates that structural flaws in China’s economic system, rather than insufficient U.S. tariff measures, are the core driver of its persistent surplus. Meanwhile, expanding U.S. fiscal deficits have also contributed to the growing trade imbalance between the two nations.

This industrial surplus issue has become a prominent political concern in the United States. Many American stakeholders fear massive Chinese excess exports will trigger a repeat of the historic “China trade shock”, eroding domestic core manufacturing sectors and displacing local industries. State subsidies and targeted industrial policies are criticized for granting Chinese manufacturers unearned competitive edges. The Biden administration has also flagged multiple strategic industries, where overreliance on Chinese supplies poses tangible national security hazards. Bilateral economic frictions cover multiple dimensions: persistent trade deficits, disruptive impacts of subsidized Chinese exports on U.S. manufacturing and employment, and systemic economic and security risks. Both the Trump and Biden administrations have adopted dual policy tools: imposing tariffs on Chinese imports and funding domestic capacity expansion in strategic fields including semiconductors, batteries and clean energy. America’s shift toward active industrial intervention and bilateral economic risk reduction partly responds to China’s industrial oversupply and escalating geopolitical frictions. Additionally, growing U.S. domestic investment in these critical sectors has lowered its willingness to accept competing Chinese imports, especially those stemming from government-subsidized surplus industries.

China’s manufacturing surplus stems from deep-rooted, long-term structural factors, which domestic economists and government authorities acknowledge create internal economic distortions. Its industrial development cycles are marked by the sudden influx of large numbers of state-owned and private enterprises into emerging sectors, even without relevant industry experience. This massive and blind market entry triggers cutthroat competition, razor-thin profit margins and inconsistent product quality. Compounding the issue, inefficient enterprises rarely exit the market in a timely manner, as local governments often sustain struggling emerging industries to safeguard regional economic interests. While firms pursue market-driven profits, fiscal support and investment from central and local governments further fuel capacity expansion. The end result is excessive production capacity beyond actual market demand, generating systemic inefficiency and volatile industrial boom-and-bust cycles. Chinese regulators describe this phenomenon as wasteful market competition, though it also accelerates low-cost product innovation and industrial upgrading. Faced with saturated domestic markets, domestic manufacturers are strongly incentivized to divert excess output to overseas markets.

Industrial surplus is prevalent across numerous Chinese sectors, including traditional fuel vehicles, steel, cement, mobile devices, mature semiconductor products, solar equipment and electric vehicles. Government intervention mechanisms driving oversupply differ by industry, as do the economic and security risks posed by China’s surplus exports. The following analysis focuses on surplus conditions within three key sectors: solar equipment, lithium-ion batteries and electric vehicles.

Solar Photovoltaic (PV) Panels

Backed by long-term state cultivation and financial subsidies, China has built a dominant position in the global solar photovoltaic sector, controlling around 80% of the world’s full PV industrial supply chain. Its industrial oversupply has brought mixed outcomes for the U.S. solar industry. Early U.S. PV manufacturing was first outcompeted by Japanese and European rivals, before being largely displaced by low-cost Chinese solar imports starting in the 2000s. Conversely, affordable Chinese solar panels have fueled the rapid expansion of America’s solar energy adoption, generating far more local jobs in installation and after-sales services than were lost in domestic panel manufacturing. Driven by China’s policy support and technological upgrades, global solar panel prices plunged by 88% over the past decade, substantially cutting costs for the U.S. clean energy transition. Nevertheless, rising U.S.-China geopolitical frictions have stoked growing U.S. concerns over overreliance on Chinese solar supplies, which are viewed as economically and strategically critical. This creates a key policy dilemma for Washington: balancing the cost benefits of China’s mature PV manufacturing capacity with the strategic need to foster independent domestic solar production chains.

Electric Vehicles (EVs)

China’s science and technology authorities launched targeted support for new energy vehicles in 2007. This policy shift responded to longstanding flaws in the traditional fuel vehicle sector, including structural inefficiencies, joint venture market monopolization and limited access to hybrid vehicle core intellectual property. Beyond easing domestic public complaints over air pollution, the initiative aims to help China seize global leading status in the EV industry.

Classified as one of China’s three core emerging strategic industries alongside solar panels and lithium batteries, the EV sector has received layered policy support from central and local governments since 2009. These incentives cover consumer purchase subsidies, preferential vehicle usage policies and the construction of public charging infrastructure, with total state support exceeding $230 billion over 14 years. A flood of traditional automakers and new market entrants have rushed into the EV track. Leading domestic brands including BYD, Geely and SAIC operate at full production capacity, while the industry is poised for future reshuffling that will eliminate small, uncompetitive manufacturers. China’s current auto exports remain dominated by fuel vehicles, though EV shipments to emerging economies, Russia and Europe are rising rapidly. Chinese-brand vehicle exports to the U.S. stay negligible, with only around 13,000 units worth $388 million sold in 2023. Notably, China’s EV production base serves global brands as well; Tesla accounted for 39% of China’s EV exports in the first half of 2023. Even with global manufacturers operating local production lines, Chinese EV firms retain clear advantages in cost control and technological innovation.

The EV industry carries far greater economic and political weight for the U.S. than the solar sector. It underpins traditional automotive manufacturing, sustains numerous local jobs and communities, and influences electoral outcomes in key swing states. Preserving a robust domestic auto industry is therefore a core U.S. economic security priority. Massive U.S. government funding for domestic EV and battery development under the Inflation Reduction Act reflects this strategic focus, even if it means short-term higher consumer costs. Additionally, modern EVs’ powerful data collection capabilities have turned Chinese vehicle imports into a potential national security risk for the United States.

Lithium-ion Batteries

China has secured global leadership in lithium-ion battery production, supplying power for consumer electronics, electric vehicles and energy storage systems. Optimizing battery cost and performance has long been a central target of China’s EV industrial policies. Unlike the booming EV sector, China’s battery industry faces slowing sales and looming excess capacity ahead of expected market consolidation. The country holds roughly 75% of the world’s lithium-ion battery production capacity, with industry leader CATL capturing over 40% of the global market, closely followed by BYD. The United States lags far behind China in battery manufacturing, hindering the development of its domestic EV industrial ecosystem. China’s full vertical integration of critical mineral sourcing, processing and battery production has created global supply chain dependence on its industry. U.S. officials view this reliance as a major strategic risk, prompting accelerated efforts to diversify supply sources — a push made more urgent by China’s export curbs on key industrial minerals. From a national security perspective, supply chain disruptions in battery materials and production could undermine U.S. manufacturing of high-performance batteries for military applications.
