What are the upstream and downstream industries of the travel agency industry?

With the increase of the experience of primary tourists and the number of middle and senior tourists, hotels, travel agencies and other tourism sub-industries need to transform into modern tourism service industry according to the changes of tourists' needs.

The upstream of tourism is the transportation infrastructure industry, which is the foundation and important premise of developing tourism. The improvement of the whole transportation system has a great promotion and guarantee for the development of tourism. The convenience of transportation in a region is not only related to the local economic development, but also affects the development of local tourism. In recent years, China's traffic facilities, especially those around tourist attractions, have been continuously improved: domestic and international flights have been increasing, intercity railways have been increasing, and expressways have spread all over the country. Comfortable and convenient transportation facilities provide a strong guarantee for the development of tourism.

The downstream of tourism directly faces the tourists who buy tourism goods (services), and the number of tourists and their purchasing power directly affect the development of tourism. Tourist groups can be roughly divided into three categories: primary tourists are inexperienced tourists, the main purpose of tourism is sightseeing, most tourist destinations are scenic spots, and tourism planning depends on travel agencies; Intermediate tourists are experienced mass market tourists, and their purpose is to explore areas outside the city where they live, so as to enrich their experience. The main tourist activities are sightseeing and entertainment, and most of them make their own travel plans through the Internet. Senior tourists are experienced and rich tourists, and their travel purpose is to relax and release pressure. Tourism activities mainly focus on sightseeing, entertainment and shopping, which requires higher living environment of tourist destinations. With the increase of the experience of primary tourists and the number of middle and senior tourists, hotels, travel agencies and other tourism sub-industries need to transform into modern tourism service industry according to the changes of tourists' needs.
