The cost that does not change with the change in production is called

Costs that do not change with changes in production are called fixed costs.

The phase in which the average cost increases with the increase in production in the long run is called the average variable cost phase.

Because in the long term all the factors of production.

It can be adjusted at any time, and there is a long period of constant return to scale from increasing to decreasing return to scale, while in the short term, the period of constant return to scale is very short or even none.

There is also a difference between the long-term average cost curve and the short-term average cost curve, which is that the long-term average cost curve is relatively flat when it declines or rises, which indicates that the average cost changes more slowly in the long run, whether it decreases or increases.

Average cost and industry average cost

The cost of the enterprise is the individual cost. The cost of each specific product in an enterprise is an individual cost relative to the average cost of the enterprise. Therefore, the concept of individual cost is relatively speaking, with the comparison of the overall difference has a great change, but the level of individual level is always the basis of the average cost level, and constantly reduce the cost of individual products and individual enterprises, for reducing the average level of individual enterprises and the whole society, and improve the overall economic efficiency.

are of great significance.

Because in the long run, all factors of production can be adjusted at any time, and there is a long period of constant returns to scale from increasing to decreasing returns to scale, while in the short term, the period of constant returns to scale is very short, or even none.

There is also a difference between the long-term average cost curve and the short-term average cost curve, which is that the long-term average cost curve is relatively flat when it declines and rises, which means that the average cost changes more slowly in the long run, whether it decreases or increases.

The total coarse fixed cost is a chain of closed stools as production changes.

a.That's right. b.Mistake.

Correct answer: B

With the increase of production, the change law of the average cost during the period of Lu Chang's letter is ()aFirst decrease, then increase, only Tanqing.

b.Increase first and then decrease.

c.has been tending to increase.

d.has been tending to reduce.

Correct answer A

The variable cost per unit of Senliang product is changed with the change of spring crack volume of production width () (

a.That's right. b.Mistake.

Correct answer: B

The total fixed cost fluctuates with the change of production, and when the output is zero, the total fixed cost is zero. （）

a.That's right. b.Mistake.

Correct answer: B

The total fixed cost varies with the change in production, and when the production volume is macro and zero, the total fixed cost is zero. （）

a.That's right. b.Mistake.

The answer is true: b
