Abstract:

Greenhouse-gas（GHG） emissions in China have aroused much interest,and not least in recent evidence of their reduction.Our intent is to place that regional pattern of CO₂ emissions and its change in context.A lengthy time perspective is combined with a cross-provincial approach and addressed through two general models,namely the industrial-energy interconnection model and the energy-CO₂ emissions interconnection model.The findings are salutary.First,they suggest that a diversified economic structure is the determined factor in not only the regional economic development but also the changing pattern of regional CO₂ emissions.For instance,the numbers of over-heavy CO₂ emissions at provincial level increased from none to two during the period between 1980 and 2000 as the local economic development dominated by industrial processes in the coastal zones gone rapidly. Secondly,they imply that the more diversified economic structure a region is,the slower increasing in energy use it has.The total energy consumption of East China between 1990 and 2000,for example,had 4% increase,when its ESD values rose from 10.5 to 23,or achieving 36% increase.Finally,together,the findings argued that the stiff structural change of energy use in China makes it very difficult for any region to reduce its CO₂ emissions.It implies that China could have a long way to go in the reduction of its CO₂ emissions if the country still resists in the traditional energy consumption pattern.
