4.2.4 Economic Rapid Growth Results in Severely Low Efficiency
and Serious Waste
China's economy experienced more than 30 years high-speed development and
created a miracle in economic development history. However, during this
process, many problems, such as low-efficient energy utilization and construction-
elimination-reconstruction-re-elimination phenomenon, can be found everywhere,
which cause severe low efficiency and serious waste.
Here we use energy utilization efficiency as an example. Although utilization level
is improved continuously, it is still 10 % lower than that of developed countries [ 8 ].
Although energy consumption per unit product of major high energy-consuming
sectors declines year by year, it is still 10-40 % higher than international advanced
level (see Table 4.5 ). It is calculated that, the energy-saving potential of China today,
technologically feasible and economically reasonably, is about 600 million ton coal
equivalent.
