Analysis of energy consumption in China's manufacturing industry

Due to the gradual increase in the energy consumption, energy shortage has become apparent in China. In this study, an index model for energy consumption is developed by collecting data from the manufacturing industry of China from 1994 to 2015, and using the method of maximum deviation. A short-term change point analysis of the energy consumption index trend is conducted based on grey relational analysis; and the change points occur in 2000 and 2008. The results indicate a decreasing trend of the energy consumption index in the manufacturing secto, and the downward trend is relatively notable from 2001 to 2008. However, the total energy consumption between 1994 and 2015 remains high as the production soared. So the Chinese government should strengthen the functions of government supervision and management, and China's manufacturing industry must focus on independent innovation to solve the existing problems.
