What Is Excess Capacity?
Let me explain excess capacity directly: it's when the demand for a product doesn't match what a business could potentially supply. If a firm is operating below its designed output level, that's excess capacity in action.
You'll often hear this term in manufacturing contexts. Picture idle workers at a plant—that's a clear sign of excess capacity. But it applies to services too. Think about a restaurant with empty tables and unproductive staff; it means the place could handle more customers, but demand just isn't there.
Key Takeaways
Here's what you need to grasp: excess capacity exists when market demand is less than what a company could supply. It's mostly tied to manufacturing, but it shows up in services as well. It can signal healthy growth, but too much of it can damage an economy.
What Causes Excess Capacity?
Several factors lead to excess capacity, and I'll outline them plainly. Overinvestment, repressed demand, technological improvements, and external shocks like financial crises are common culprits. It can also come from misjudging the market or poor resource allocation. To keep things balanced, company leaders must stay in tune with supply and demand realities.
Why Does Excess Capacity Matter?
Excess capacity matters because while it might indicate growth, an overload can hurt the economy. If a company can't sell products at or above cost, it risks losses from underpriced sales or wasted inventory.
Consider this important point: too much capacity might force plant closures, leading to job losses and wasted resources. A business with heavy excess capacity could bleed money from high fixed production costs. On the flip side, it can benefit consumers through discounted prices using that spare capacity.
Companies might even keep excess capacity on purpose as a strategy to block new competitors from entering the market.
Example of Excess Capacity: China
Take China as a real-world example. Since 2009, its economy has faced its third wave of excess capacity, following earlier periods from 1998-2001 and 2003-2006. Despite becoming the world's second-largest economy in 2010, China deals with ongoing internal and external challenges. Excess capacity hits manufacturing hard, especially in steel, cement, aluminum, flat glass, and automobiles.
Rampant Excess Capacity Persists in China
The Chinese government has tried various measures, but the problem lingers. In most industrial economies, excess capacity corrects itself short-term. But in China, its severity and duration point to deeper economic issues, with big implications for global trade given China's market influence.
Excess Capacity in China's Automobile Market
Auto plants carry high fixed costs, and many new ones in China rely on local government incentives, creating pressure to stay open and keep jobs—even if output can't be sold. This leads to excess cars sparking price wars, lower profits domestically, and floods of exports to places like the U.S. For firms like General Motors, who count on China for major sales, this spells trouble.
How Long Could It Last?
There's little motivation to cut excess capacity in China. Closing a new factory risks upsetting local governments, and after nearly two decades, it doesn't seem likely to end soon.
Then Came COVID-19
The COVID-19 pandemic hit the auto industry hard. In February 2020, China saw auto sales drop over 80%. With over 80% of the global auto supply chain linked to China, disruptions there affected makers worldwide. Most companies expected revenue hits in 2020 from the pandemic. Since it started in China, recovery might begin there first, but it's too early to gauge long-term effects on the economy or China's ongoing excess capacity issues.
