China’s overcapacity debate and how to avoid a collision course

Chinese companies are rapidly gaining market share in strategic industries amid increasing accusations of subsidy-induced overcapacity. But what does ‘overcapacity’ actually mean, how concerned should we be, and what might happen next?

The debate on overcapacity is heating up

Discussions about China’s overcapacity issue have been ongoing for many years. Most recently, various industries, such as those dealing with solar panels, wind turbines, steel, and cement, have started to debate the issue.

The discourse was reignited following US Treasury Secretary Janet Yellen’s visit to China in April, where she brought up concerns about industrial overcapacity, noting that China’s economy was too large to “export its way to rapid growth,” and called for shifting away from state-driven investment and returning to market-oriented reforms.

In our view, the overcapacity debate is not really about overcapacity in its most precise term, but rather what we call “problematic overcapacity”, when a country’s excess capacity begins to crowd out international competitors and affect industry development in other countries.

While overcapacity has affected various sectors at different periods of history, we will focus on the recent concerns which are primarily focused on the question of overcapacity in the green economy, in particular the new energy vehicles (NEV) sector where Chinese firms have quickly become among the world’s most competitive.

The crux of the issue on the overcapacity debate boils down to friction over two of China’s economic transitions, with the first moving up the value-added ladder, and the second the green transition. There is a fear that China’s state-led investment and support will increasingly be directed into strategic industries and cause market distortions and competitive imbalances. China’s attempt to move into the upper end of the value chain naturally rings alarm bells for those currently occupying this domain.

We expect it will be difficult to avoid friction given the rise of protectionism, heightened geopolitical friction, and the sheer scale of China’s economic transition. However, drawing upon Japan’s experience in the 1970s-80s, there is still room for some win-win solutions, such as increasing Chinese investment abroad.

In this report, we aim to explore key talking points of the most recent debate, the current state of China’s industrial capacity, and the potential ways forward.

‘Problematic overcapacity’ explained

It’s always useful to clarify what is being debated; when people are talking about overcapacity, what exactly are they talking about?

The textbook definition of overcapacity is usually along the lines of when production capacity is higher than expected sales. Discussions of overcapacity on a macro level are less clear-cut, which likely explains why some deny there is an overcapacity issue at all while others think it is a crisis.

The most straightforward definition is a sum of the parts calculation of the current utilisation rate, where when the rate drops significantly below average it could be deemed to be in overcapacity. However, we’ve also seen some use a definition of overcapacity as when domestic supply outweighs domestic demand, while others include future projections in the overcapacity definition.

In our view, it may be helpful to distil the debate down to a question of “problematic overcapacity”, which can be described as when exports of excess production start crowding out or significantly damage industry competitors globallyThere is certainly a grey area on where this begins, but typically when a country’s production capacity is enough to cover a dominant share of (or in egregious cases, the entirety of) aggregate global demand, or when the producers engage in dumping, it could be deemed to be problematic overcapacity.    

Anxiety over Chinese overcapacity likely stems from recent experiences within the solar industry, where industrial policy contributed to Chinese solar panel producers’ global leadership and solar panels becoming one of the “new three” exports, but also resulted in a price war which saw many firm failures and industry turmoil.

  • China has achieved and retained dominance in the industry, accounting for 80% of global solar module production capacity in 2023, and now holds the most important role in global supply chains.  
  • From a global and industry level, solar panel prices have fallen drastically, helping many locations reach grid parity. As a result, solar power generation globally surged a massive 30-fold between 2010 and 2021 to more than one million gigawatt hours. Various downstream jobs have been created.   
  • The solar industry underwent rounds of consolidation amid heavy competition, and many companies (including Chinese and global competitors) faced bankruptcy or acquisition.

With the dust settling, was the solar industry case seen as a success or a failure? From China’s perspective, the answer would appear to be the former. Despite volatility along the way, after cutthroat competition leading to survival of the fittest, many of the global solar champions are Chinese. Competition has also helped bring the industry from a niche sector needing subsidies to a viable form of energy generation in many locations.

In the most recent debate, the overcapacity discussion is largely centred on another of the “new three” exports, namely the NEV sector. The rise of Chinese NEVs has rapidly turned China from a net importer of autos as recently as 2019 to the world’s largest auto exporter in 2023.

The rise of Chinese NEV manufacturers has been facilitated by a more advantageous backdrop compared to many global competitors. There is a significant amount of contention around the topic of subsidies and their impact, but overall the industry has benefited from a supportive policy environment and public infrastructure investment which facilitated NEV adoption, including building charging stations and scaling the market and supply chains. Many entrepreneurs have piled into the sector after signals of government support and after the success of some NEV sector early movers.

With China’s domestic auto sales and exports starting to slow, production continuing to grow rapidly, and prices starting to drop, some observers have watched with concern that the NEV sector could go down the same path as the solar panel industry.

The key arguments

Since Yellen’s comments in April, we’ve seen a plethora of voices chime in with their opinions. Here are some of the key talking points from both sides:

“Chinese overcapacity is a problem”

  • “Rising Chinese dominance of select industries will harm industry development and workers in other countries.”
    • Given the scale of China’s manufacturing industry, excess capacity is not just a domestic but a global issue.
    • Countries will want to protect their investments in strategic sectors and secure a share of the market.
    • The industries currently in the spotlight (particularly the auto sector) are crucial to many economies, particularly in Europe.
    • Overreliance on any country for strategic sectors carries an element of risk, with concerns about supply chain security and geopolitical factors.
    • Oligopolistic risks rise if no intervention is taken, as survival of the fittest will crowd out smaller players.
  • “China’s overcapacity is exporting deflation to the rest of the world.” This argument is that China’s excess capacity ends up being exported at lower prices than similar goods in other markets, which in theory causes a deflationary impact.
  • “Industrial policy usage goes beyond historical norms.”
    • There is an implicit tolerance of “normal” industrial policy use. For example, infant industry protection is often seen as a viable form of industrial policy; without intervention, many industries would have no chance of surviving.
    • At an indeterminate point, behaviour turns from acceptable to anti-competitive. While it is a grey area, many accusations are that China has passed this threshold.
    • Zombie firms contribute to overcapacity globally. Firms that should have failed under normal market competition are artificially kept alive via supportive policies and prevent correction of excess production.
  • “Overcapacity is a symptom of poor resource allocation.” This argument is more domestic rather than trade-focused. Overcapacity pulls resources away from other areas where they may be more productive to a sector that does not need the extra investment. This is why China has discussed the overcapacity problem for the past two decades.

“Chinese overcapacity is not a problem”

  • “The overcapacity critiques are inherently flawed.” Given the overarching nature of this response, we split some common arguments into several categories.
    • Free market ideology indicates that countries with competitive advantages in specific areas should invest in them, and there is nothing wrong with producing and exporting more than domestic demand. As long as supply does not eclipse global NEV demand, overcapacity beyond domestic demand is not a problem.
    • Industrial policy may lead to excess capacity, but subsidies are a net positive as they translate into lower prices for the end consumer. This mentality is more emblematic of the peak globalisation era where trade was a win-win prospect rather than a mercantilist competition.
    • “Unfair competition criticisms are unmerited.” A common argument from China’s side is that its advantages in the NEV market are not due to subsidies, but due to economies of scale, innovation, as well as complete supply chain integration. Currently, other than a purchase tax waiver for NEVs (which has been adopted by other countries as well), there does not appear to be official NEV sector subsidies in place. Proponents of this argument often view tariffs as discriminatory measures with no merit.
  • “Overcapacity exists, but global sustainability goals should outweigh the fight for market share and profits.”
    • Less effort should be expended on fighting over who will profit from the green transition, and more effort made toward moving the world toward a more sustainable path.
    • Adding tariffs on price-competitive green products undermines global sustainability efforts.
    • Achieving climate goals provides a positive externality well beyond the benefits of securing a larger green economy market share.
  • “Overcapacity is temporary and will self-correct.”
    • Industrial policy may create overcapacity, but the problem will self-correct as market forces cause survival of the fittest.
    • Excess capacity will eventually grow, especially amid ambitious carbon goals in China and globally.
  • What the data tells us about overcapacity
  • An 80% capacity utilisation rate is sometimes described as an ideal level, with higher levels unsustainable and lower levels a waste of capacity. However, by this definition, the majority of economies are facing an overcapacity issue. In practice, this is more of an arbitrary and aspirational level rather than a firm level to target, but it is helpful in providing a point of reference.
  • China’s overall industrial capacity utilisation rate fell to 73.6% in the first quarter of 2024. Aside from the major shock from Covid lockdowns, capacity utilisation has mostly fluctuated between 73-78% over the past decade.
  • How does China’s capacity utilisation stack up internationally? Looking at the data, China’s capacity utilisation on a national level is somewhat toward the lower side, but still well above the lowest levels. The United States, for example, had a utilisation rate of 77.4% in the first quarter of 2024, Germany’s was a healthy 81.3%, while South Korea’s and Thailand’s came in lower at 71.3% and 60.5% respectively. On a country level, China does not appear to be facing a significant overcapacity problem. 
  • While this data should be taken with a grain of salt, as country-level capacity utilisation data is already somewhat shaky, and it is uncertain if methodology across countries is consistent, it provides a rough international comparison.
