During the ancient inn period (12nd century-18th century), with the development of commodity production and commodity exchange, the inn gradually developed. The earliest inns can be traced back to the end of primitive society and the beginning of slave society, which were produced to meet the needs of diplomatic exchanges, religious and business trips and cruises of emperors and nobles in ancient countries.

During the luxury hotel period (from the end of 18 to the middle of 19), with the emergence and development of capitalist economy and tourism, tourism began to become an economic activity, and luxury hotels serving the upper ruling class came into being. There are many accommodation facilities named "hotels" on the European continent.

The period of commercial hotels (from the end of 19 to the 1950s) is the most active period of hotels in the world. It is an important stage in the development of the hotel industry, which eventually makes the hotel industry a service industry for ordinary people and lays the foundation for the modern hotel industry in all aspects.

During the period of modern new hotels (after 1950s), after World War II, with the worldwide economic recovery and prosperity and rapid population growth, international mass tourism appeared worldwide. The increase of people's disposable income has rapidly expanded the number of people traveling abroad and enjoying hotel services, and accelerated the popularization of tourism activities and frequent political, economic and cultural exchanges between countries around the world. This change in social demand has prompted the hotel industry to enter the modern hotel period.

As a special commodity form, restaurants attract people to spend more money to enjoy things that they can't enjoy at home and elsewhere. By providing high-quality services such as trading places, conference places, accommodation, catering, leisure and entertainment, we can make profits, which will directly contribute to the development of the national economy.

Hotel is a foreign trade operation mode of non-export commodities, and its exchange rate is higher than that of commodity exports to a certain extent. Therefore, hotels are an important industry to earn foreign exchange, which can help the country balance its foreign exchange expenditure.

Hotel industry is a comprehensive service industry, and its vigorous development will inevitably lead to the development of other industries in society, such as construction, furniture, decoration, textile, chemical industry, food processing industry and so on. Greatly promoted the activity of the national economy.
