Car firms buy in raw materials (steel),intermediate goods (windscreens,tyres) and labour to make cars.Windscreen and tyre companies hire workers and also buy raw materials from other industries.What is the value added of the car industry?(见图）
答案是1000-120=880。
the value added of the car industry = value added of car firms + value added of windscreen companies + value added of tyre companies
= (sales price of car - material cost of car) + (sales price of windscreen - material cost of windscreen) + (sales price of tyre - material cost of tyre)
= (1000 - 250 - 100) + (150 - 10) + (100 - 10)
= 650 + 140 + 90
= 880
= (sales price of car - material cost of car) + (sales price of windscreen - material cost of windscreen) + (sales price of tyre - material cost of tyre)
= (1000 - 250 - 100) + (150 - 10) + (100 - 10)
= 650 + 140 + 90
= 880
