The cost of making in China has been rising in recent years, and the cost of making in China is close to that of the United States, according to data from the Boston Consulting Group of the United States. Based on the United States (100), the manufacturing index in China is 96, that is, the same product costs $1 to be made in the United States and $0.96 to be made in China. Although labor costs in China have risen, the income of Chinese workers is significantly lower than that of workers in the same industry in the United States.
The statement 'The profit margin of China's manufacturing industry is generally low' can best explain the above seemingly contradictory phenomena.
