Secondly, the construction-elimination-reconstruction-re-elimination during
China's economy development results in not only the low accumulation of wealth,
but also poor quality of economy development. Periodic energy waste is extremely
serious. Generally speaking, industrial facilities in developed countries including
European countries and USA can be used for more than 40 years while buildings
above 100 years. Looking back the thirty years economic development in China,
numerous industrial equipments and buildings with the same age are given blasting
demolition with merely 10-year industrial equipments and 30-year buildings.
Those infrastructure which should be reserved for the next generations as
precious wealth now turns to be a heavy burden on environment. Large quantity
of periodic energy waste, therefore, is generated as a result of shortening of
construction cycle and severe environment pollution emerges as well.
4.2.5 Energy Transportation Pressure Continues to Increase
and Bottleneck Is Obvious
Center of China's energy consumption is in east coastal area and south region while
coal resource mainly distributes at north China, oil and gas resource in east, middle
and west part, water in southwest, which forms a pattern of North to South and West
to East Coal Transportation, North to South Oil Transportation, West to East Power
Transmission, and West to East Gas Pipeline. This results in long distant transpor-
tation for large amount energy, which places heavy pressure on road and railway
transportation in China.
