First of all, from the perspective of supply and demand, the US delegation is hungry, but the unit price is low, but many riders are willing to run, mainly because the market demand is large and the supply is relatively insufficient. With the rapid development of Internet and take-away industry, consumers' demand for sales services is increasing, while the number of riders is growing relatively slowly, resulting in insufficient market supply. In this case, the rider faces more delivery orders. Although the unit price is low, riders can still get higher total income by accepting more orders.

Secondly, from the rider's personal point of view, the reason why they choose the US delegation to be hungry is also related to factors such as income, job stability and technical support. For riders, income is one of the most important considerations when choosing a distribution platform. Although the unit price of Meituan is low, riders can increase their income by accepting more orders because of their large market share and many orders. In addition, if you are hungry, Meituan provides a more powerful distribution management system and technical support, so that riders can complete distribution tasks more quickly and efficiently, thus improving work stability and income level.

Finally, market competition is also one of the factors that affect the unit price of the US delegation and the choice of riders. In the fiercely competitive take-away market, the distribution platform may adopt some preferential policies in order to attract more riders and users. For example, increase the commission ratio and tips to reduce the unit price of the platform and attract more riders to join the platform. These preferential policies can improve the income and job stability of riders to a certain extent, thus attracting more riders to choose the US group to be hungry.

To sum up, Meituan is hungry, but many riders are willing to run at a low unit price, mainly because of the large market demand and insufficient supply, as well as the rider's personal income, job stability and technical support. At the same time, market competition is also one of the factors that affect the choice of riders. These factors interact, which makes Meituan hungry and gain a high market share and competitiveness in the take-away market.
