新零售是指個(gè)人、企業(yè)以互聯(lián)網(wǎng)為依托，通過運(yùn)用大數(shù)據(jù)、人工智能等先進(jìn)技術(shù)手段并運(yùn)用心理學(xué)知識，A new retail model that upgrades and transforms the production,circulation,and sales processes of goods,reshapes the business structure and ecosystem,and deeply integrates online services,offline experiences,and modern logistics

　　“新零售”模式打破了線上和線下之前的各自封閉狀態(tài)，線上線下得以相互融合、取長補(bǔ)短且相互依賴，More functions of transaction and payment are performed online, while offline platforms are usually used as screening and experience platforms,高效物流則將線上線下相連接并與其共同作用形成商業(yè)閉環(huán)。Under the"new retail"model,consumers can freely travel in an intelligent,efficient,fast,affordable,and enjoyable shopping environment,greatly improving their shopping experience,and thus satisfying the strong desire of young people to upgrade their consumption.
