"But what are the weaknesses of “The Chinese Model”? According to most experts at least 10 could be identified:
• China’s economic growth is input driven. This means that massive amounts of labour, capital and raw material are used in volumes that might not be sustainable for ever."
Of course, every economy is in that category.
I think the author's point is that, if China doesn't dramatically improve the efficiency with which it uses labor, capital and raw materials, prices/shortages might dramatically limit future growth.
no, he means that China aims not to get more efficiency or productivity, not even after they've captured the market.
