1. Variety: The main variety of Chinese fast food is Chinese food, which solves the problem of convenient dining for consumers. The main varieties of western-style fast food are mainly western-style fast food. Although some oriental dishes are also provided, they are often used as supplements and are relatively expensive.

2. Cost performance: Chinese fast food is reasonable in price, healthy and nutritious, and suitable for people's long-term dining consumption. Western fast food has a good dining environment and is convenient for leisure, but the cost is two or three times that of Chinese fast food, which is very high.

3. Standardization: Due to the variety and technical limitations, Chinese fast food is far from mass standardized production. However, with the help of modern technology, many Chinese fast food chain brands are trying to break through the technical bottleneck of standardization and gradually solve the problem of slow production.

Generally speaking, the differences between Chinese fast food and western fast food in consumption behavior are mainly reflected in three aspects: variety selection, cost performance and standardization.
