【明報專訊】AFTER six years China's gross domestic product (GDP) has grown at an annual rate beginning with 6 again. In the third quarter of this year, it fell to 6.9% instead of remaining 7%. And it keeps falling. Judging from internal and external factors, the downturn has yet to bottom out. However, that has caused no wild fluctuations in investment markets. This shows people are no longer surprised that the second largest economy now grows at a medium-high rate rather than a high rate. They accept the new normalcy of China's economic restructuring. That said, an economic downturn has to do not only with perception. It is actually mirrored in all economic aspects. For example, once an industry shrinks rapidly, unemployment will rise, and social stability may be jeopardised. Therefore, to the authorities, it is a grim challenge to find ways to maintain a proper balance of restructuring.
