1 Introduction

China’s rapid economic transformation to become the world’s second-largest economy is inextricably linked to its investment-led growth model. This investment has been financed by high levels of domestic savings resulting from a number of government policies.^[1] These savings have been channelled into a financial system that has provided highly-subsidised lending for infrastructure, manufacturing and real estate investment. As a result, China has achieved high rates of economic growth by ramping up its level of investment faster than most other countries at a similar level of development (Chart 1, panel a).^[2]

Nevertheless, this investment-led growth model is coming under increasing pressure. First, diminishing rates of return imply that it is becoming more difficult to generate growth from one additional unit of investment, and some observers believe that China has long passed the point at which it can productively absorb these high rates of investment. Second, a policy-driven severe downturn in China’s property sector, which accounted for about 30% of GDP before the real estate downturn in 2021, is set to sustainably diminish this major pillar of domestic demand. Third, external demand is also shrinking, as trade tensions are increasing and a rising number of trading partners are unwilling to further accommodate higher trade deficits with China. More generally, structural challenges, including an ageing population and low productivity growth, are adding to the headwinds faced by China’s economy.

In response to these challenges, China’s government is redoubling its efforts to spur growth through investment-centric policies. This additional push to boost investment appears to be driven almost exclusively by the state-owned sector, whereas fixed asset investment by the private sector has stalled since the onset of the housing crisis in 2021 (Chart 1, panel b). Government policies to expand output in the face of slowing demand have potential implications for China’s trading partners. A supply-driven expansion of production could materially affect trade prices and hence inflation in their economies. The shift towards manufacturing previously-imported advanced goods is designed to enhance China’s self-reliance, thereby reducing the import intensity of its growth while shifting competitiveness and trade balances in relation to its trading partners.

Against this background, this article will briefly summarise China’s investment-led growth model and assess supply-demand imbalances in its manufacturing sector. It will then evaluate the potential spillover effects for China’s trading partners and review the policy implications for key advanced economies.

2 The evolution of China’s economic growth drivers

Investment remains a major growth driver in China. In the 30 years leading up to 2010, the share of investment in China’s GDP gradually rose from 35% to 47% (Chart 2). By comparison, the typical investment-to-GDP ratio for developed economies is about 20%, whereas post-Soviet countries averaged about 30% in the first ten years after their transition to a market economy. Over the same 30-year period, the share of final consumption fell steadily from about 65% to below 50% in 2010. By comparison, the contribution of net trade to annual growth ranks significantly below that of investment and consumption. The net trade contribution to annual real GDP averaged 0.9 percentage points in the 1990s and since 2000 has averaged 0 percentage points. While integration into global value chains was instrumental in its technological development, China continued to have a high rate of imports, partly due to imports of intermediate goods processed for manufacturing exports but also imports of investment goods, such as machinery, to upgrade its productive capacities. For many decades, high investment rates provided the necessary upgrades to infrastructure and modernised China’s production technology, helping the country to become a global manufacturing powerhouse.

However, over time, high rates of investment face diminishing rates of return. Despite already high rates of investment, China’s government proceeded with two further investment waves after the global financial crisis. The first was a response to the Great Recession, which saw the Chinese government implement a large-scale stimulus programme focusing on infrastructure and real estate, bringing annual state-financed fixed asset investment growth rates in 2008 and 2009 to 36% and 60% respectively. Once the stimulus policies came to an end, however, significant overcapacity had built up in a number of sectors. By 2015 the government reacted with supply-side reforms, which among other things aimed to reduce excess industrial capacity in specific industries, resolve unprofitable firms and reduce the stock of unsold housing.^[3] The second investment wave started in 2020 as a response to the coronavirus (COVID-19) pandemic, when the Chinese government targeted its support programmes at firms with the aim of increasing growth across all manufacturing sectors, including those previously subjected to capacity reduction efforts in 2015. As a result, productive capacity built up again owing to supply-driven factors, outpacing demand, which was more subdued as a result of the zero-COVID policy.

Structural and cyclical factors are increasingly weighing on demand

Since the global financial crisis, GDP growth has been on a secular decline in China, partly due to structural headwinds. Total factor productivity (TFP) began to decline as additional infrastructure spending enhanced productivity less over time. While aggregate annual TFP growth was 2.8% in the ten years leading up to the Great Recession, it slowed to 0.7% over the period 2009-18. In addition, China’s working age population started to decline in 2011. According to UN estimates, by 2050 it will have declined by nearly a quarter. These headwinds are already depressing China’s potential growth rate and this downward trend is likely to persist (see Box 1 for a model-based analysis).

In addition, cyclical demand factors became negative during the pandemic. Consumer demand fell sharply during the pandemic, as uncertainty amid pandemic restrictions led to a rise in precautionary savings (Chart 3). This was sustained by the housing crisis, which started in 2021 and further depressed consumer demand, given that the dominant share of household wealth in China is linked to the property sector.

The current housing crisis is likely to make future investment less inward facing

The housing crisis severely impaired one of the three main pillars of investment growth. Total fixed asset investment in China consisted predominantly of three categories in roughly equal parts: infrastructure, real estate and manufacturing. The rapidly growing housing sector increasingly coincided with rising levels of leverage among developers, while the stock of housing began to outstrip demand in a growing number of regions. The Chinese authorities took steps in 2020 to rebalance and derisk the sector. With new restrictions on leverage, the derisking policies are also designed to achieve a long-term reduction in the overall size of the sector in terms of share of GDP. The resizing of the sector, amid a liquidity crisis among developers, led real estate investment growth to turn negative in late-2021 (Chart 4). In the absence of the real estate investment pillar, the investment-led growth model now relies more heavily on infrastructure and manufacturing investment to support economic growth.

(year-to-date year-on-year growth)

Infrastructure and manufacturing investment are more likely than housing investment to be export oriented. China’s push to become self-reliant and further develop its high technology sector implies that its infrastructure spending is changing. There will be less emphasis on building roads and bridges and more on building new infrastructure aimed at developing sectors, such as telecommunications networks, high-speed rail networks, and research and development facilities, which support advanced manufacturing. The most recent announcements made by China’s government to build “new productive forces” to shore up growth targeted these sectors. Specifically, the government aims to support new technology sectors such as electric vehicles (EVs), microchip technology and new materials. Given the subdued outlook for domestic demand as a result of the ongoing housing sector weakness, this additional capacity will materialise over the next few years to a significant extent in the export sector, which will have potentially important implications for China’s trading partners.

3 China’s development of manufacturing capacity

The build-up of manufacturing capacity in China is historically unparalleled. China’s share of gross global manufacturing production rose from 5% to 35% over the course of 1995-2023, and it currently has a higher manufacturing output than that of the next nine largest manufacturing countries combined (Chart 5). This unprecedented rise in productive capacity did not just serve China’s large and growing domestic market but coincided with a rapidly rising share of world manufacturing exports, which grew from 3% in 1995 to 20% by 2020. If China is now aiming to invest further in productive capacities, this raises the question of whether the additional capacity will be absorbed domestically or externally.

Chart 5

Shares in global manufacturing value added by country or area

(percentage share)

There are signs that the recent rise in manufacturing output is creating distortions in the Chinese market. The supply of Chinese industrial firms outpaced demand, resulting in a build-up of inventories and a decline in prices, ultimately reducing firms’ profitability. The number of loss-making firms has doubled to 28% since 2018 in tandem with a considerable increase in the inventory-to-sales ratio (Chart 6).

(percentage share and ratio, 12-month moving average)

China’s trading partners have been increasingly vocal about their level-playing-field concerns, as production surpluses are often linked to extensive government support. China’s industrial policy measures account for a much larger share of GDP relative to other economies (Chart 7). While direct subsidies account for only a small share of all measures, indirect subsidies, such as preferential access to lending, lower financing costs and land allocation are much more common.^[9] These policies are predominantly accessible to public firms and government-linked private firms, while private and foreign firms do not have the same preferential access.^[10]

Tracing excess capacity in China’s manufacturing sectors

Signs of rising overcapacity can materialise in different forms across sectors. The building of excess capacity can be defined as a level of production that cannot be absorbed by demand at current prices. An increase in output would thereby increase inventories, be sold at lower prices, or a combination of both. We provide three types of evidence for the existence of overcapacities in China, namely an overview of Chinese inventories and profits by sector, the latest business survey data of European companies in China, and a structural Bayesian VAR analysis of Chinese exports. First, we find that in a wide range of sectors, which together represent the majority of China’s manufacturing sector, the inventory-to-sales ratio has increased, highlighting that Chinese domestic output is currently expanding faster than sales (Chart 8). This is particularly evident for sectors linked to real estate, which faced a sudden and severe decline in domestic demand (especially in the cement, steel and metal products industries). Second, recent survey evidence confirms the existence of overcapacities and their disinflationary effects. In a recent survey by the European Union Chamber of Commerce in China, over one-third of respondents among European companies in China observed overcapacity in their industry in the past year and cited overinvestment as the main reason.^[11] Moreover, in the sectors where overcapacities were observed, prices tended to decline. Overall, it emerges that where domestic demand cannot absorb the additional output, producers will aim to direct this excess capacity to export markets, often by lowering prices.

The rise in Chinese output is predominantly supply driven. As a third piece of evidence for the existence of overcapacities, a structural Bayesian VAR analysis is carried out to disentangle demand and supply factors in Chinese export growth.^[12] It shows that in real estate-related industries, such as steel and other metals, exports over the past year have been almost entirely driven by supply factors, while foreign demand remained broadly neutral or negative (Chart 9, panel a). The same dynamics can be observed for motor vehicle exports (Chart 9, panel b). More generally, when comparing the share of supply factors in exports by sector, we find that over the past year, supply factors have become a growing driver of exports across a range of sectors compared with the 2017-19 period (Chart 9, panel c). The results show that the share of foreign demand in the exports of sectors related to the real estate and advanced manufacturing sectors in particular appear to be falling.

4 Global implications of China’s investment policies

China’s efforts to further invest in the productive capacities of highly subsidised industries has global implications for its trading partners. To the extent that additional output cannot be entirely absorbed domestically and external demand remains broadly constant, a rise in China’s exports necessitates a further increase in its global share of manufacturing exports. Given recent tariff action against China, a further expansion of its export market share may not go unchallenged in global markets. Moreover, by lowering prices or increasing exports of heavily-subsidised products, a rise in exports could lead to international spillovers of disinflationary pressures. These could be further exacerbated if trading partners’ domestic firms in turn lower their prices to remain competitive with Chinese exports. Finally, with China’s development of its advanced manufacturing capacities, particularly in green technology sectors, the relatively larger size of state subsidies in China could also affect the competitiveness of trade partners in these relatively new and growing advanced manufacturing sectors.

Impact on euro area prices by sector

A static exercise modelling a further decline in Chinese export prices in sectors with overcapacity would have a downward impact on euro area consumer prices, which could be amplified through a subsequent decline in euro area producer prices. To quantify the potential impact, we perform a sectoral bottom-up analysis based on the elasticities of international production networks captured in input-output tables.^[13] We first assume a 30% drop in Chinese export prices in sectors identified as having overcapacities in our BVAR analysis.^[14] The decrease in price is calibrated by considering past price movements in the solar panel industry, as this industry can serve as a case study for potential developments in other green technology industries.^[15] The simulation results find that the decline in Chinese export prices would lead to a 0.3 percentage point fall in euro area consumer price inflation. This result consists of a smaller direct impact through consumption of Chinese final products, and a larger indirect impact through intermediate input linkages, reflecting the rich interdependencies of euro area and Chinese production networks. Second, we look at how this change is amplified if euro area producers lower their prices in response to cheaper Chinese products. We consider a 7% decrease in the prices of euro area producers. This is calibrated by considering the differential in government subsidies between China and Germany, as German subsidies account for about one-quarter of those of Chinese producers.^[16] The price reduction by euro area producers in affected sectors results in an additional 0.6 percentage point drop in euro area consumer price inflation (Chart 10). While the imposition of tariffs could mitigate this impact, it could vary across different products and producers and potentially lead to retaliatory measures.

Impact on China’s competitiveness

China’s share of global exports has been consistently increasing, particularly in the advanced manufacturing and green technology sectors. These gains in market share can be observed across the board, including in industries where we find traces of overcapacity (Chart 11).^[17] Rapid expansion is particularly evident in the new green technology industries, where China’s growing share of the solar panel industry serves as a cautionary tale for other emerging green industries (Chart 12). To assess the potential scenario where the electric vehicle industry follows a similar trajectory to the solar panel industry, Box 2 attempts to quantify the potential impact a 50% decrease in EV prices would have on prices and market shares in the euro area and other countries.

China has increased its competitiveness in sectors traditionally dominated by advanced economies. Along with rising market share, China’s value added in global value chains has also been growing.^[18] This increase in value added is enhancing China’s competitiveness and exposing advanced economies to competition in a greater number of sectors, as China gradually develops a comparative advantage in sectors in which the latter specialise. In the last 20 years in particular, China has become increasingly competitive in sectors previously dominated by other advanced economies (Chart 13). Of these advanced economies, Italy appears to be most exposed because China has become competitive in 60 sectors where Italy holds a comparative advantage. On the other hand, Germany has seen the largest surge in exposure to Chinese competitiveness, which has increased from 20 sectors in 2000 to 50 in 2022.

China’s aim of boosting its self-reliance will impact its demand for imports and its competitiveness in third-country markets. It has been aiming to reduce its reliance on global trading partners by importing less and by vertically integrating its value chains.^[19] As it gradually replaces imported goods with domestically-produced ones, China’s demand for imported industrial goods will decline. A surge in the domestic production of industrial goods will also increase competition from China in third-country export markets. Both phenomena will put downward pressure on the trade balance of industrial goods exporters, such as the euro area. At the same time, the change in the trade balance is likely to affect the renminbi exchange rate, which will offset part of the gain in China’s price competitiveness.

Impact on competitors’ prices

China’s competition will also give rise to further disinflationary pressures through second-round effects emerging as a result of competitors being forced to lower the prices of their products. While Chinese production surpluses in some sectors may not affect the market shares of firms in advanced economies directly, they could lead to the reallocation of production from third markets to China, leading to overall lower prices for these products. At the same time, competitive Chinese prices could force producers in advanced economies to also reduce their prices. Both cases could potentially trigger second-round effects on consumer prices in advanced economies.

Box 2
A model-based assessment of the spillovers of Chinese subsidies to electric vehicles

Prepared by Maria-Grazia Attinasi, Lukas Boeckelmann, Bernardo de Castro Martins and Baptiste Meunier

China increasingly subsidises electric vehicle producers, mirroring what happened in the solar panel industry where it has become a global leader thanks to massive state aid. Overall, industrial subsidies in China are estimated to be three to nine times higher than those in advanced economies, with conservative estimates showing subsidies amounting to €221 billion (2% of China’s GDP). There has recently been a huge increase in subsidies to Chinese green tech companies, notably to producers of electric vehicles.^[20] This approach mirrors how China has become a world leader in the solar panel industry, increasing its global market share from 5% in 2000 to 50% in 2024 through massive government subsidies.^[21]

Global spillovers are quantified using a state-of-the-art, multi-country, multi-sector model run on a newly-developed granular input-output table. We use the Baqaee and Farhi (2024) model, which accounts for amplification effects of shocks through global production networks and substitution effects via international trade.^[22] The model makes it possible to simulate the propagation of shocks both downstream to consumers and upstream to suppliers, and to derive the non-linear effects of shocks across countries and sectors. By enhancing the granularity of available input-output tables in the calibration of the model to isolate green sectors, such as EVs, our methodology enables us to simulate shocks targeted only at green sectors and to recover the sectoral impact on the industries of interest. ^[23] We simulate a hypothetical and stylised scenario where the relative price of Chinese EVs and electric batteries drops by 50% following government subsidies, in line with estimates of the price differential between Chinese and EU producers.^[24]

Massive Chinese subsidies would lower the price of EVs for consumers across the globe but would also severely downsize their domestic production in the rest of the world. Heavily-subsidised Chinese EVs are estimated to lower the price consumers pay for EVs by 30% globally and 15% in the EU (Chart A, panel a). This leads to a 6% increase in the global production of EVs, as consumers substitute thermal vehicles for cheaper EVs, but EU domestic production would decline by 70% (Chart A, panel a) as consumers switch to cheaper Chinese products. As a result, China substantially increases its global market share in EVs by 60 percentage points, notably at the expense of EU producers, whose share shrinks by 30 percentage points (Chart A, panel b), of which 18 percentage points relate to German producers. This scenario closely resembles what happened in the solar panel industry, where Chinese subsidies made products cheaper and enabled China to gain a dominant market share while producers in the rest of the world were forced to scale back production. Finally, even though the sectoral impact on the EV industry is sizeable, the global impact is limited: total consumer prices decline by only 0.2% and overall EU production falls by a mere 0.1% owing to the small size of the EV industry.

The estimates presented in this box should be considered an upper bound for losses in market shares for the euro area as the model abstracts from potential mitigating effects. First, EU producers may react endogenously to Chinese subsidies by lowering their prices or by bridging the price competitiveness gap through more innovation and digitalisation.^[25] The EU could also impose countervailing duties, such as the new tariffs announced in June 2024 and not accounted for in the box.^[26] The scenario considered in the box instead illustrates, other things being equal, the risks related to sizeable Chinese subsidies. Second, consumer preferences for EVs might be less price sensitive than assumed in our scenario. While we account for this in the Baqaee-Farhi model by setting a product-specific elasticity of substitution, estimates in the literature relate to all vehicles and not specifically to EVs.^[27] Should price sensitivities for EVs be lower than for other vehicles, this could lead to an over-estimation of the substitution effects towards Chinese EVs.

5 Conclusion

China’s recent policy approach to address economic weakness by doubling down on its investment-driven growth model and identifying new productive sources is widely expected to increase already existing overcapacities. Given diminishing marginal returns to investment, the continued emphasis on the supply side of the economy is leading to rising inventories, lower profitability and growing supply-demand imbalances in a number of sectors and industries. Against a background of subdued domestic demand, efforts to direct additional productive capacities to export markets is fuelling tensions in global trade relations.

Trade policies vis-à-vis China are changing rapidly. The United States recently introduced a sharp increase in tariffs on Chinese imports, notably raising tariffs on Chinese EVs from 25% to 100%. Moreover, other countries are also increasing tariff and non-tariff barriers to Chinese imports (Chart 14). In the EU, several trade policy instruments were introduced that address level playing field considerations in public procurements and also review dumping practices. The changing trade policy dynamics are also increasingly visible in trade flows. Since 2017-18, China’s share of imports has been on a declining path in the United States and Japan, albeit briefly interrupted by the pandemic, when demand initially focused temporarily on medical products and then on manufacturing goods made in China. By contrast, China’s share continued to rise in the EU, currently standing above pre-pandemic levels (Chart 15).

Given these shifting trade policy dynamics, the role of the EU as an export market for China could potentially become more central. In the event that non-EU countries further close their markets to Chinese products, China could redouble its efforts to export to the EU, thereby exacerbating the impact on Europe in terms of rising disinflationary pressures, a loss of competitiveness in advanced manufacturing sectors and a declining share in both manufacturing output and exports. Given the potentially significant effects on output, inflation and labour markets, the European policy response needs to be carefully calibrated to ensure level playing field conditions.^[28]
