Abstract
Since the resources from environment are in short supply, it is necessary to alleviate the conflict between high-speed economic construction and limited resources in the Chinese society. This paper aims to analysis the variation of natural resources input into China during 2000-2007 based on extended exergy as an eco-centric metric. With the materials, labor, capital and environmental renovation quantified by exergy numeraire grounding on the second-law metric in view of ecological accounting, the composition and proportion of extended exergy clearly revealed the whole condition of available energy input into society in China. Moreover, two indexes, i.e., extended exergy consumption intensity and extended exergy productivity of natural resources, are proposed to depict the contribution of four different production factors from economic, social and environmental aspects, respectively. Moreover, the extended exergy based analysis of the Chinese society may be helpful in uncovering the long-term resource depletion and promoting efficiency of the resource transformation in the social-economic-environmental system, thus providing holistic method and systematic view for the decision makers with respect to environmental management.
Extended exergy-based ecological accounting of China during 2000-2007
Since the resources from environment are in short supply, it is necessary to alleviate the conflict between high-speed economic construction and limited resources in the Chinese society. This paper aims to analysis the variation of natural resources input into China during 2000-2007 based on extended exergy as an eco-centric metric. With the materials, labor, capital and environmental renovation quantified by exergy numeraire grounding on the second-law metric in view of ecological accounting, the composition and proportion of extended exergy clearly revealed the whole condition of available energy input into society in China. Moreover, two indexes, i.e., extended exergy consumption intensity and extended exergy productivity of natural resources, are proposed to depict the contribution of four different production factors from economic, social and environmental aspects, respectively. Moreover, the extended exergy based analysis of the Chinese society may be helpful in uncovering the long-term resource depletion and promoting efficiency of the resource transformation in the social-economic-environmental system, thus providing holistic method and systematic view for the decision makers with respect to environmental management.
