The brand promotion of McDonald's is very successful, with more than 3 1000 stores in 18 countries and regions around the world, achieving double growth in sales revenue and profits. Wechat brings more data-driven to the whole enterprise. Before, we didn't know which customers came and what they bought. Now, through a complete membership system, we can fully understand where customers are, who they are, what they like and why they come. This also gives us a more accurate insight and planning on new product research and development, marketing, restaurant operation and even supply chain management.

For example, on the member's day every month, McDonald's can know exactly which member received the coupon, which restaurant he used to spend it in, and also infer how likely he is to come to the restaurant to participate in the activity from the previous big data. Every restaurant can accurately estimate the passenger flow and make preparations in advance.

Usage rate is the best feedback from customers. McDonald's uses big data to analyze and optimize the use and stay of different modules. The applet also adds customer service and feedback functions to collect more direct feedback from customers. Mobile payment is the general trend in China. The mobile payment ratio of McDonald's China is 80%, which is very high in the global McDonald's system. In the future, the coverage of McDonald's China restaurant will be one of the highest in the world.

The distribution service scale of McDonald's in China is not available abroad. Delivery requires the restaurant to have high operational efficiency. China has become the fastest growing and most important foreign fast food market. In the economic recession, China's economy is more stable than other countries and regions, which will attract foreign fast food to do business in China.
