Why can't the neutral derby match the double-ring drive?

1, debt ratio. Zhongda Lide and Green have lower harmonic debt ratios, while the double-ring drive has higher debt ratios. It is because the double-loop drive needs a lot of money to invest in research and development and expand the production scale, while the harmonics of Zhong Da Lida and Green are relatively stable.

2. The gross profit margin of green harmonic is lower, followed by medium power harmonic, and the double-loop drive is the highest. It is because the product positioning of double-ring transmission is higher and more professional, while Li Zhongda is oriented to the mass market and the product positioning is relatively low.
