There are some differences between JD.com and Amazon's models. First, JD.com is a self-operated e-commerce platform, and its main operating model is to purchase inventory directly and then sell it to customers. Amazon, on the other hand, is a diversified platform that sells both self-operated products and products from third-party sellers. In addition, Amazon focuses on providing a high-quality customer experience and is committed to improving delivery speed, service quality, and after-sales service, while JD.com pays more attention to product quality and safety. Overall, the two companies have different business models and development paths, but both have achieved high commercial success.
