新零售是指个人、企业以互联网为依托，通过运用大数据、人工智能等先进技术手段并运用心理学知识，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”模式打破了线上和线下之前的各自封闭状态，线上线下得以相互融合、取长补短且相互依赖，More functions of transaction and payment are performed online, while offline platforms are usually used as screening and experience platforms,高效物流则将线上线下相连接并与其共同作用形成商业闭环。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.
