Exports registered $208.5 billion, increasing by 9.4 percent year on year, while by contrast, imports amounted to $158.6 billion, decreasing by 2.4 percent year on year. As a result. China＇s trade surplus has been continually expanding. The trade surplus in August reached $49.8 billion, expanding by 77.8 percent and trade surplus of the first eight months was $200.5 billion, increasing by 30.3 percent. The vastly expanded trade surplus in August reflects that China＇s trade imbalance is worsening.展开更多

Still topping the list are large state-owned enterprises （SOEs）, with Sinopec, PetroChina and China State Construction Engineering continuing to occupy the first three positions. Inspiringly, a total of 36 rapidly grow- ing companies like online retailer JD.com nudged into the list for the first time, mirror- ing a mushrooming Chinese economy. Aside from that, the list has reflected some po- tential systemic problems regarding China＇s economic growth.展开更多

Such an incident is not without precedence. However, its repeated occurrence gives one pause for thought and presents some thorny questions. As banks have taken away the bulk of the profits generated by enterprises, how can the real economy sustain itself？. In turn, if the real economy continues its downward slide, how will the financial industry be able to maintain its juicy earnings？展开更多
