The analysis of the profitability of the product operations above shows that Suning Tesco's fees and costs have increased year-on-year, affecting profits. To quickly increase market share, Suning Tesco will increase its investment and save some of the costs, although some costs are essential. Logistics costs are a big part of it, and if you can control it well, it's very important for businesses. Suning Tesco has warehouses in almost all current-level cities. Because sales conditions are different, the lack of proper connectivity with vendor information can lead to backlog or surplus products, which increases costs and inventory management is also very important. In 2017, labor costs exceeded 7.7 billion, and if we can improve the level of workforce efficiency, we can reduce this cost.
