The question is, in fact, not that complicated. There are a lot of people who say the cost is high. That answer is essentially right, but it doesn't answer the questioner's question. Because who can answer, why is the cost high? First of all, with all devices, research and development costs are high. However, if the cost can be amortized with huge quantities, then the R&D cost plus can be ignored. Let's say if a cell phone can sell a million units. Then the R&D cost of a million units is only amortized to 10 dollars. However the number of medical devices is too small. China's more than three hundred cities, even if an average of three units per city, the whole country is only a thousand units (in fact, taking into account the existence of different models, a single medical device ownership is generally less than this number). This number cannot amortize the R&D costs. Even production costs are difficult to amortize. The above phenomenon has resulted in the medical equipment itself being sold at an extremely expensive price. So many small and medium-sized hospitals use the equipment in the form of leasing. They also have to pay expensive annual fees. Another cost is repair. The repair of these equipments is not supposed to be too costly. However, the same is a matter of quantity, these devices are very small, know these devices are also very few people, in the medical equipment repair industry so many people in the business, there is no need for people to give up their profits. At the same time, medical equipment maintenance are also public affairs, are urgent matters, so the price is never negotiable, which also caused the industry's considerable profits (compared to some other industries, of course, can not be considered profiteering, but a medical equipment maintenance personnel to earn more than two million a year is a very normal thing, individuals even higher). In general, the total retention of medical equipment is small, high barriers to entry, doomed to this market is a relatively lucrative market, and hospitals have to pay a considerable price for this (anyway, the money from the patient out of pocket). This is all the reason why the examination fee is expensive.
