The China Bubble’s Coming — But Not the One You Think | Foreign Policy: “Is the Chinese economy operating in a different economic reality? Will it continue to grow, no matter what the global economy is doing?
The answer to both questions is no. China’s fortunes over the past decade are reminiscent of Lucent Technologies in the 1990s. Lucent sold computer equipment to dot-coms. At first, its growth was natural, the result of selling goods to traditional, cash-generating companies. After opportunities with cash-generating customers dried out, it moved to start-ups — and its growth became slightly artificial. These dot-coms were able to buy Lucent’s equipment only by raising money through private equity and equity markets, since their business models didn’t factor in the necessity of cash-flow generation.
Funds to buy Lucent’s equipment quickly dried up, and its growth should have decelerated or declined. Instead, Lucent offered its own financing to dot-coms by borrowing and lending money on the cheap to finance the purchase of its own equipment. This worked well enough, until it came time to pay back the loans.”
