Two. Content of infrastructure construction

Infrastructure refers to the physical engineering facilities that provide public services for social production and residents' life, and it is a public service system used to ensure the normal social and economic activities of a country or region. It is a general material condition for social survival and development. Infrastructure includes not only public facilities such as roads, railways, airports, communications, water, electricity and gas, which is commonly known as material infrastructure, but also social undertakings such as education, science and technology, medical and health care, sports and culture, which is social infrastructure.

Infrastructure includes transportation, post and telecommunications, water supply and power supply, commercial services, scientific research and technical services, landscaping, environmental protection, cultural education, health services and other municipal public works facilities and public life service facilities. They are the foundation of national economic development. In modern society, the more the economy develops, the higher the requirements for infrastructure; Perfect infrastructure plays a great role in accelerating social and economic activities and promoting the evolution of their spatial distribution. It often takes a long time and huge investment to build a perfect infrastructure. For new and expanded projects, especially major projects and base construction far away from cities, priority should be given to the development of infrastructure, so that benefits can be brought into play as soon as possible after the project is completed.

Third, the significance of infrastructure construction

Infrastructure construction has the so-called multiplier effect, that is, it can bring several times the total social demand and national income of investment. Whether the infrastructure of a country or region is perfect or not is an important basis for its long-term sustained and stable economic development.

In 1930s, in response to the unprecedented Great Depression,

American President Roosevelt carried out the famous Roosevelt New Deal, one of which was the large-scale infrastructure construction led by * * *. These infrastructure projects not only increased employment and people's income, but also laid a solid foundation for the great development of the American economy in the later period.

Four characteristics of infrastructure construction

Precedents and foundations

Public services provided by infrastructure are essential for the production of all goods and services. Without these public services, other goods and services (mainly direct production and business activities) will be difficult to produce or provide.

Most infrastructure services are difficult to import through trade. A country can finance and introduce technology and equipment from abroad, but it is unthinkable to directly introduce airports, highways and water plants from abroad as a whole.

Integral inseparability

Usually, only when the infrastructure reaches a certain scale can it provide services or provide services effectively. Small-scale investment can not play a role in roads, airports, ports, telecommunications and water plants. For example, the power station dam should not be built only in the middle of the river, the airport runway should not be unfinished, and the light rail connecting the two cities should not be built only in half.

Quasi-public goods

Some infrastructure services are relatively non-competitive and non-exclusive, similar to public goods. Non-competitiveness means that the production cost of goods will not increase with the increase of consumption places, that is, the marginal cost is zero. For example, public goods such as national defense, the annual defense expenditure is fixed, and will not increase because of the addition of a baby this year.

Question 2: What is used to reinforce the equipment foundation? Score 5: If the original concrete foundation can only use cement, or add some steel bars, it is better to use grouting materials instead of cement for foundation grouting.

Question 3: What does infrastructure mean? Infrastructure refers to the physical engineering facilities that provide public services for social production and residents' life, and it is a public service system used to ensure the normal social and economic activities of a country or region. It is a general material condition for social survival and development.

Question 4: What is large-scale infrastructure? Large-scale infrastructure is an important support for regional social and economic development, and its benefit output is mainly based on basic functions such as transportation, safety and production.

Question 5: What does infrastructure mean? Hello, classmate, I'm glad to answer your question!

Infrastructure Infrastructure is the basic system of a country.

The qualification examination for futures practitioners is an entry examination for futures practitioners and a national qualification examination.

The qualification examination for futures practitioners is to enable relevant domestic personnel to better grasp the basic concepts, principles and knowledge of the futures market, be familiar with the general laws of the development of the futures market, the principles of the futures market and its operation process, and understand the basic business of the futures market, the basic methods and procedures of participating in futures trading, and the strategies and skills of futures trading; Through the study of futures law and supervision system, they can better understand and master the basic legal knowledge, main legal system and supervision system of futures market, enhance their legal concept, law-abiding awareness and self-discipline awareness, and thus improve their professional level. According to the Measures for the Administration of Futures Practitioners, China Futures Association is responsible for organizing the qualification examination.

I hope my answer can help you solve the problem. If you are satisfied, please adopt it as the best answer.

Thank you again for your question. More accounting questions are welcome to be submitted to enterprises in Gao Dun.

Gao Dun wishes you a happy life!

Question 6: What are the tourism infrastructure and supporting facilities? What is the difference? Help ~ 1. Infrastructure: infrastructure in a narrow sense only refers to water, electricity and roads. Infrastructure in a broad sense mainly includes transportation, communication, water conservancy and hydropower, urban water supply, drainage and gas supply, power supply facilities and fixed assets needed to provide intangible products or services for science, education, culture and health departments.

2. Tourism supporting facilities are related facilities serving the tourism industry. In addition to infrastructure, it mainly refers to tourist reception facilities (including parking lots, hotels, restaurants, etc. ), tourist shopping facilities, entertainment facilities and medical rescue facilities.

Difference: the design of infrastructure should not only meet the living needs of local residents in tourist areas, but also meet the needs of tourists for infrastructure; Tourism supporting facilities mainly meet the tourism demand of the tourism industry, and the design is oriented to the needs of tourists.

Question 7: What are the basic service facilities? Facilities that can directly serve people's food, clothing, housing and transportation are infrastructure; Such as: front road, environmental greening, sewage treatment, ground drainage, etc.

Question 8: What is the concrete method of building the roof? Please explain in detail the unified standard GB 50300 for construction quality acceptance of building engineering.

Appendix C Division of Construction Engineering Division (Sub-division) and Sub-project

Question 9: What is infrastructure construction, the infrastructure of the main building? Infrastructure is the temporary facilities on the construction site, such as office area, hardened pavement, residential area, warehouse, etc. Of course, there are also permanent and hardened roads that may be used permanently, as well as drainage and so on. Buildings are generally divided into main body, foundation and foundation. Foundations include raft foundation, strip foundation and independent foundation. , to bear the main load and transfer it to the foundation. I'm a novice, too. I hope the experts can give me some advice.
