RT-Mart

RT-Mart is a Chinese hypermarket chain and, as of the late 2010s, the country's largest foreign-invested supermarket by sales. It entered mainland China in 1998 and, after 11 years of competing with Carrefour and Walmart, surpassed both in 2009 with 40.4 billion yuan in sales . Its parent company is Sun Art Retail Group (高鑫零售), which also operates the Auchan (欧尚) brand .

The chain is distinguished by its enormous store footprint—roughly 27,000 square meters per location, with over 20,000 SKUs—and an unusual "sub-landlord" model where rental income from leasing space within its stores effectively covers its own occupancy costs, in some cases generating surplus . In 2017, Alibaba made its largest single investment to date in Sun Art Retail, and the partnership accelerated RT-Mart's online transformation through Taoxianda (淘鲜达), Tmall Supermarket, and Ele.me integration, plus a B2B service called "e路发" targeting small retailers within a 20-kilometer radius . Founder Huang Mingduan (黄明端), who stepped down in early 2018, returned as CEO in March 2019 to lead what he described as an 18-month transition period with expected losses . By mid-2019, the chain reported its B2C operations were running over 700 orders per store daily with 99.7% on-time fulfillment, while maintaining overall profitability .
