The technology level determines the profit level and the number of competitors. From the perspective of the entire motor industry, the average profit level is in the shape of a u-shaped distribution, and the number of competitors is in the shape of an inverted u-shaped distribution, according to the related research reports on household appliances. At present, the gear motor industry has a high degree of marketization and a large number of motor enterprises. The whole industry is in the process of integration and optimization. Small motor and large motor are at the highest end of the whole u-shaped curve due to high technical difficulty, large upfront investment and high technical threshold, which is a high average profit level and a few competitors. Small power motor and medium size motor are in the middle of the whole u-shaped curve, which is a low average profit level and many competitors.
