Abstract：This paper focuses on energy cost and environmental loss of keeping rapid economic growth and developing heavy and chemical industries in China. It designs and calculates elasticity ratio of SO2 emission, and then investigates that ratio and elasticity ratios of energy and electricity consuption from 1999 to 2003 by official statistical data. It also investigates energy consumption and pollutant emissions in per GDP unit, and in per value-added unit of industrial sectors concerned in 2003. The results show that energy especially electricity growth rate and some pollutant emission growth rate, in most years, were higher than GDP growth rate during the period, and also some heavy and chemical industries consumed much more energy and discharged much more pollutants. It also compares China's energy and environmental data with that in some other countries, tries to recognize the improving space of energy use and environment for China's future development,and asks some questions on economic developing pattern in China.
