The report of 18th National Congress of the Communist Party of China (CPC) raised a new goal to double people's income by 2020 from 2010. This requires the Party to not only stimulate domestic demand but also balance supply and demand, said Huang Hao, associate professor of Chinese Academy of Social Sciences.

"The online purchase platform shows great consuming capacity, which offers a channel to balance supply and demand as some commodities were transferred from traditional sellers," Huang said.

Some companies transferred their storage from downtown department stores to e-commerce depots right before Single's Day, which created a new way to decrease the storage of traditional retailers, he said.

"The large social collaboration triggered by e-commerce marketing pushes the limits of each one in the chain. More peaks will come to be both tests and chances," said Zhang Yong, president of Tmall.com.

Ma Yun, board chairman of Alibaba Group, which runs Taobao.com, said that e-commerce is complementary to advanced traditional retailer in the US.

"However, China's infrastructures and traditional retail industry is not perfect enough, which gives e-commerce a chance to become mainstream to stimulate domestic demand, while logistics and other supporting facilities can improve and match up," Ma said.
