Evaluating the interplays among economic growth and energy consumption and CO 2 emission of China during 1990–2007

Abstract

The interplays among economy and energy and environment have been widely concerned. This paper put forward several indicators to quantify the relationships among economic growth and energy consumption and CO 2 emission. As an example, these indicators were applied to evaluate the comprehensive performances of China during 1990–2007. The results show that Chinese people has been living a better life with Chinese rapid economic growth but not synchronously in urban and rural areas. Non-carbon energy resources share has increased; however, fossil energy resources have still acted as the main driver for Chinese economic growth during this period. Technical progress has improved the fossil energy efficiency of Chinese economic activity, which leads to CO 2 emission per unit GDP and CO 2 emission per capita unit GDP dropping simultaneously; however, the two indicators’ annual decline rates become smaller and smaller, which reflects that technical progress’ role is dropping and economic scale's effect is climbing. People's survival has a rising contribution to CO 2 emission. CO 2 emission per capita has increased, which shows that economic scale has greater impact on CO 2 emission than technical progress does. Relatively speaking, Chinese development patterns have become more and more sustainable during this period. Finally, based on the related issues being discussed, some corresponding suggestions are put forward for Chinese government to further coordinate the relationship among economic development and energy consumption and CO 2 emission. The proposed indicators can form a set of useful tool for policy-makers to promote the harmonious development of economy and energy and environment in different regions and countries.
