The "Double 11" promotion season is in progress. The sales data of multiple platforms show that the sales of high-end household appliances, digital products, "China-Chic" brand and other categories have increased significantly, among which the growth of upgraded categories is obvious. Industry analysis shows that high-quality products and services have become an important factor to stimulate the vitality of the consumer market.

The reporter noted that in the near future, several departments have jointly deployed to increase the supply of high-quality products and services from the supply side, so as to better release the potential of the consumer market. On November 1, Suning E-shop released a report showing that during the first round of "Double 11", the sales of green energy-saving household appliances in Suning E-shop offline stores increased by 126% month on month, the sales of high-end household appliances above 10000 yuan increased by 137% month on month, and the sales of Chinese household appliance brands accounted for more than 60%.

It can be seen from the "Double 11" data that with the continuous improvement of the quality and level of production and supply of consumer goods, upgrading products have become an important growth point in the consumer market. Taking smart home appliances as an example, according to the data released by the Ministry of Industry and Information Technology recently, the market size of smart home appliances in China has reached 500 billion yuan, new categories of home appliances such as dishwashers and floor sweepers have developed rapidly, and new durable consumer goods have accelerated their entry into ordinary people's homes.

Among them, a large number of household appliances that have been used for more than 10 years or even longer are still in service, and there is huge room for market upgrading. In the opinion of Wang Qing, the deputy director and researcher of the Market Economy Research Institute of the Development Research Center of the State Council, with the steady growth of residents' income and the continuous improvement of market supply, residents' consumption has entered a new round of upgrading and reform period, and the demand for diversified, personalized and high-quality consumption has continued to increase.
