Answer: 1. The economy in technical economics mainly refers to the rational use of resources.

2. The research field of technical economics.

Technological economics is the study of economic problems and economic laws in the field of technology, and the study of technological progress and economic growth.

The science of the interrelationship between them is to study the optimal allocation of resources in the field of technology, and to find the best combination of technology and economy for sustainable development.

of science. 3. The analysis of technical economics.

The economics of technology is mainly concerned with the following aspects of economic activity.

Analysis of technical feasibility and economic effects:

1. Rational development of various resources and combined utilization of potatoes.

2. Selection of excellent agricultural varieties.

3. Selection of various industrial raw materials and materials.

4. The first generation of energy and the first product.

5. Adoption of new technologies, new processes and new equipment.

6. Formulation of various standards and series.

7. The shape and structure of the product.

8. Specialization, collaboration and union of production.

9. Enterprise scale.

Layout and structure.

10. Determination of construction methods and construction cycles.

11. Selection and cooperation of various transportation, post and telecommunications, and communication methods.

12. Environmental pollution prevention and control methods.

13. Reasonable selection of process conditions and process parameters.

14. Reasonable choice of imported technology.

Fourth, the research object of technical economics.

1. Relational theory, which believes that technical economics is a discipline that studies the interrelationship between technology and economy to achieve the best configuration of both.

2. Factor theory, which believes that technical economics is a discipline that studies the optimal combination of technological factors and economic factors.

3. Problem theory is considered to be a discipline that studies technical and economic problems in the field of production and construction.

4. The theory of motivation is a discipline that studies how to make rational, scientific and effective use of technological resources and make them a driving force for economic growth.

5. Effect theory, which holds that technical economics studies the economic effects of technological activities.

6. Synthesis theory (system theory) is a discipline that studies the structure, function and laws of a large system composed of technology, economy, society, ecology and value.

Engineering economics believes that the economy is the purpose and driving force of technological progress. Technology is the means and method of economic development, and capital, as a factor of production, can generate time value in any situation.

In general, economic value should be calculated using the intermittent compounding method; The time value of funds is often calculated by the method of continuous compound interest; The time value of the capital is a kind of value-added of the capital generated by the passage of time, so it is created by time.

Engineering Economics Fill-in-the-Blank Questions Economy is the foundation and driving force of technological progress, and technology is the means and necessary condition for economic development

Technical economics is a science that studies economic problems and economic laws in the field of technology, it is a science that studies the interrelationship between technology and economy, seeks the best combination of technology and economy, and is a marginal science where technical science and economic science intersect 46

Technology and economy are inextricably linked. As a powerful means for human beings to develop productive forces, technology has a very obvious economic purpose. The purpose of developing technology is to apply it, to transform it into real productive forces, and to promote economic development.

The transformation of scientific and technological achievements into productive forces and the implementation of engineering projects are the most basic economic construction activities, and they are inseparable from technical means. As a result, technology and economics are both mutually reinforcing and mutually restrictive.

The economics of technology is the study of how to make the most effective use of technological resources for economic development. One of its main tasks is to analyze and evaluate specific development projects, engineering projects, and technical solutions from an economic point of view, so as to provide a scientific basis for correct decision-making.

The study of the economics of technology is broad and covers a wide range of industries or fields of technology. Due to the different production characteristics of various industries or technical fields, the technical and economic problems faced by them are also different, and some problems are common and can be solved by adopting a unified research method. However, some problems are specific to the industry or technical field, and must be studied using special index evaluation systems and methods.

The parameters that reflect the technical performance of the technical solution are called technical indicators; Data that reflect the economic aspects of technical solutions are called economic indicators; The indicators that comprehensively reflect the comparative relationship between technology and economy are called technical and economic indicators. One of the basic tasks of the study of technological economics is to establish the methods and index system of technological and economic evaluation, and to establish the relationship between technical and economic indicators, technical indicators, and economic indicators 32 34

For geological drilling construction, it is necessary to adopt a technical and economic evaluation system and index system in line with the actual production according to the technical characteristics of the industry, compare the economic effects of different technical schemes, and select the best scheme.

Technical economics is a science that studies the economic problems and economic laws in the field of technology, studies the interrelationship between technological progress and economic growth, studies the optimal allocation of resources in the field of technology, and seeks the best combination of technology and economy for sustainable development. It mainly analyzes the technical feasibility and economic effects of the following aspects of economic activities: the rational development and comprehensive utilization of various resources; selection of excellent agricultural varieties; selection of various industrial raw materials and materials; energy production and**; the adoption of new technologies, processes and equipment; the development of various standards and series; the shape and structure of the product; specialization, collaboration and federation of production; the size, layout and structure of the enterprise; Determination of construction methods and construction cycles; the selection and cooperation of various modes of transportation, post and telecommunications, and communication; environmental pollution prevention and control methods; Reasonable selection of process conditions and process parameters; Reasonable selection of imported technology, etc.

A total of 15,000 * 4 = 60,000 yuan is required.

Let's say the amount of money deposited per year is x. Then the deposit at the end of the 19th year is x*((1+8%) 10+(1+8%) 9+.1+8%)) Here it can be simplified with the formula of summation of proportional sequences. The resulting data is x*(

The interest is calculated after spending 15,000 in the 20th year, which is (x*(Same for 21 and 22 years.) In this way, after spending 15,000 yuan in the 23rd year, it is exactly 0, and the equation is:

((x*(Then I had to peel it off layer by layer.) Get the end of the 19th year as x* (

Find x Question 2:

Gain 1.25 million yuan in 5 years, and if you can earn another 500,000 yuan. Earned a total of 1.75 million yuan. The total amount of money after the event was 3.75 million yuan.

I think the value of the return should be profitable, so:

If the annual rate of return is 20%, it is 2 million * (1 + 20%) 5 = 10,000 yuan.

This investor is greedy for a bah ah .........Housing prices are ......... that are speculated by this kind of person

Method 1: 250 (p f, 20%, 5) + 25 (p a, 20%, 5) = <200 so it is not cost-effective.

Method 2: 200 (f p, 20%, 5) = > 250 + 25 (f a, 20%, 5) = 436 so it is not cost-effective, and there are questions to add qq
