The elevator emergency production profit low enterprise difficult to control?

Why are the domestic elevators and the production industry being in a state of not much prosperity now? In fact, before there are many experts have given this advice, they pointed out that because the emergency equipment market demand is not very optimistic, more important is the equipment at the time of production cost is relatively high, but sadly the profit is too low, so the enterprise has no way can control.
Because the elevator emergency equipment has certain professionalism, enterprises need to invest more manpower and material resources in the production process. At the same time, we need to provide professional personnel, such as technicians and supervisors, to control the whole production process. After the completion of the equipment production, the later enterprises also need to promote the equipment through a certain channel and sell more performance. In this process, there is no doubt that the enterprise needs to bear a greater pressure, whether it is on the capital, or the spirit.
Therefore, faced with the current high production cost, many enterprises can only produce the emergency related edge equipment for elevator, but can not touch part of the core technology and equipment. As for whether the future situation will change, experts only give a prediction, and for practical development, enterprises need to pay more in practice input, so that we can change the embarrassing situation of today's production.
