これまでのところ、中国経済は米景気減速の目だった影響を受けておらず、中国経済は米国経済から最も"decouple"(分離)されていると考えられている。中国経済の最近の発展には米国を中心とした世界経済の好景気が大きな影響を与え、世界の工場として中国の経済発展に寄与してきた、と言うのが元々の理解であったと思うが、米国経済の減速の中で、中国経済が堅調さを保つ中、世界経済についての強気派の最近の最も強い論拠がこの"decouple"論である(米国が駄目でも、中国を始めとした新興国経済が世界成長を支える)。
ただ、この"decouple"論にも懸念が生じている。ニューヨーク大学Roubini教授は、これまで米国の経済不況が住宅に集中していたために中国経済に大きな影響を与えなかったが、一度個人消費に不況が及んだら、米国不況の影響を受ける最大の餌食は中国だろう("recouple")と言う。そして、中国の減速により、影響を受けるのは東アジアの国(日本、韓国等)であるとの見方を示している。
現にPorts of LA and Long Beachの対前年比のグラプを以下につけているが、中国製品の米国への輸出は明らかな減速を示しており、2001年以来の0水準に落ちることが懸念される。

Nouriel Roubini writes: Recoupling rather than Decoupling: the Forthcoming Contagion to China, East Asia and Emerging Markets
Paradoxically China is the one country that has, so far, decouple the most – both in real and financial terms from the U.S. but it will also be the first and most serious victim of a U.S. led recession. The decoupling of China is clear as its growth rate has not decelerated, in spite of the U.S. slowdown, and its financial markets have – so far – blissfully avoided (thanks in part to its financial system partially isolated via capital controls from the global one) the turmoil and volatility that hit the US and Europe since the summer. But the reason for the Chinese growth decoupling is that, until recently the US slowdown was still modest (short of the coming hard landing) and it was not concentrated in private consumption but rather housing: China is mostly exporting low-priced consumer goods to the U.S. and the recoupling of China will occur soon once the US consumer recession is in full swing. Thus, the biggest victim of a US consumer led recession will be the country – China - that, so far, has decoupled the most from the US.
...
No wonder that Chinese officials have started to express serious concerns about the current sharp slowdown in Chinese exports to the US, from an annualized growth rate of over 20% in Q1 to a rate of 12.4% in Q3 of this year ("If demand in the US drops further, Chinese exporters will be devastated by a rapid and continuous fall in orders," a Chinese official report said).
...
And once there is a sharp growth slowdown in China the next victims of this recoupling will be East Asia and commodity exporters.

The (second) graph shows the Year-over-year change in Chinese exports to the U.S. Note: this graph uses a 3 month centered average to calculate the YoY change.

Since the last data point (trade data) is for September, and I'm using a 3 month centered average, the last plotted point is for August (9.5% YoY change).
Looking at data from the
Ports of LA and
Long Beach, the YoY change might be close to zero soon - something that hasn't happened since the 2001 recession.
