2. Infrastructure construction content
Infrastructure refers to material engineering facilities that provide public services for social production and residents’ lives, and are used to ensure national or regional social and economic activities. The public service system is operating normally. It is the general material condition on which society depends for its survival and development. Infrastructure includes not only public facilities such as roads, railways, airports, communications, water, electricity, and gas, commonly known as physical infrastructure, but also social undertakings such as education, science and technology, medical care, sports, and culture, which are social foundations. Facilities (social infrastructure).
Infrastructure includes transportation, post and telecommunications, water supply and power supply, commercial services, scientific research and technical services, landscaping, environmental protection, culture and education, health services and other municipal public engineering facilities and public living service facilities, etc. . They are the basis for the development of various undertakings in the national economy. In modern society, the more the economy develops, the higher the requirements for infrastructure; perfect infrastructure plays a huge role in accelerating social and economic activities and promoting the evolution of their spatial distribution patterns. Establishing a sound infrastructure often requires a long time and huge investment. For new construction and expansion projects, especially major projects and base construction far away from cities, it is even more necessary to prioritize the development of infrastructure so that the benefits can be exerted as soon as possible after the project is completed.
3. The significance of infrastructure construction
Infrastructure construction has the so-called multiplier effect, that is, it can bring total social demand and national income several times the amount of investment. Whether a country or region's infrastructure is perfect or not is an important basis for whether its economy can develop sustainably and stably in the long term.
In the 1930s, in response to the unprecedented economic depression,
U.S. President Roosevelt implemented the famous Roosevelt New Deal, one of the most important policies was*** Leading large-scale infrastructure construction, these infrastructure projects not only increased employment and people's income, but also laid a solid foundation for the later development of the American economy.
Four characteristics of infrastructure construction
Priority and basicity
The public services provided by infrastructure are the production base for all goods and services. Indispensable, without these public services, other goods and services (mainly referring to direct production and business activities) will be difficult to produce or provide.
Non-Tradability Most infrastructure provides services that are almost impossible to import through trade. A country can finance and introduce technology and equipment from abroad, but it is unimaginable to directly import airports, highways, and water plants from abroad as a whole.
Integral indivisibility
Under normal circumstances, infrastructure can only provide services or provide services effectively when it reaches a certain scale, such as roads, airports, ports, telecommunications, water plants, etc. In this industry, small-scale investment cannot play a role. For example, the power station dam cannot be built only to the middle of the river, the airport runway cannot be left half unfinished, the light rail connecting the two cities cannot be built only half, etc.
Quasi-public goods
The services provided by some infrastructure are relatively non-competitive and non-exclusive, similar to public goods. Non-competitiveness means that the production cost of an item will not increase as the place where the item is consumed increases, that is, the marginal cost is zero. For example, for public items such as national defense, the annual defense expenses are fixed and will not increase because of a new baby born this year.

2. Tourism supporting facilities are all related facilities that serve the tourism industry. In addition to the minimum infrastructure, they mainly refer to tourist reception facilities (including parking lots, hotels, restaurants, etc.), tourist shopping facilities, Entertainment facilities, medical rescue facilities, etc.
Difference: The design of infrastructure must not only meet the living needs of local residents in tourist destinations, but also meet the needs of tourists for infrastructure; tourist supporting facilities are mainly to meet the tourism needs of tourism and take tourists’ needs as the priority. Design Orientation
Question 7: What are the basic service facilities? Facilities that can directly serve people’s clothing, food, housing and transportation are infrastructure; such as: front roads, environmental greening, sewage treatment, ground drainage etc.

Question 9: What is the infrastructure construction and the main body of the building? Infrastructure is Temporary facilities at construction sites, such as office areas, hardened roads, residential areas, warehouses, etc. Of course, there are also permanent ones. Hardened pavement may be used permanently, as well as drainage and so on. Buildings are generally divided into main body, foundation and foundation. The foundations include raft foundations, strip foundations, independent foundations, etc., which carry the main load above and transmit it to the foundation. I am also a newbie, and I hope the experts can give me some advice.
