So at least industry is onto its own hard-edged problem. In another sign that things are bad enough to stir up a rethink, China's central government is looking at new recipes. It has banned new turbines as wind power loses gale force (if it ever had any) and moved to control steel input, among other largely ineffective measures.
Also on the eve of the annual political convention this week, President Xi Jinping sounded an alarm through the official Xinhua news agency. The alarm didn't mention debt or overcapacity, but let's not read too little into it:
"The world's second-largest economy now stands at a crossroad after 30 years of fast development, in want of a more qualified growth and a fairer system,"
says. "China's growth, for one thing, is still plagued, to some extent, by an inefficient growth model of high investment and low return."
Central officials, however, tend to run hot on policy ideas but cold on any idea how much of a grip local authorities already have over day-to-day reality. Overcapacity is likely to linger for a while, touching investment in various forms.
Sino-foreign joint ventures that once looked attractive -- possibly because the Chinese partner got a cheap loan for the project -- will cool quickly if capacity spills too far over.
, for example, signed a deal last year with
China Power Investment Corp.
to work together on a range of aluminum and energy projects, worth a total of $7.5 billion. They set up a company in Shanghai to make aluminum products for aerospace, consumer electronics and commercial transportation in China.
Even if China Power Investment Corp. runs at ideal capacity, Alcoa may get caught in a downturn in the aluminum industry as a whole as Chinese official media have hinted at a coming slump of up to five years.
Suppliers to China's target industries, such as factory equipment maker
Hitachi Plant Technologies
, will also see orders ease if Chinese manufacturers cut back.
On the brighter side for overseas firms, China's trade relations will change if overcapacity worsens. Indebted, unprofitable companies would, in theory, push (dump?) less stuff on nations such as the United States to relieve capacity, meaning less-crowded home markets. Weaker pressure from Chinese metal imports should boost business, and share prices, for non-Chinese resource giants such as
But if overcapacity suddenly flattens Chinese GDP growth, global markets won't like that at all because they look to China for global economic direction. Markets from Hong Kong to New York would slide until an equivalently heavy piece of good news comes along.
