On China´s Endosomatic and Exosomatic Metabolism: An Application of Analysis of Societal Metabolism

The "metabolism of human society" is a concept used to characterize the processes of energy and material transformation in a society which are necessary for its continued existence. In order to improve the traditional input-output analysis method and the black-box analysis model, the societal metabolic ecosystem of china was divided into different components to establish societal metabolic ecosystem model to analyze metabolic processes and account the eco-flows between components, and determine the hierarchy relationship between the various components. Two indexes (the contribution index and the development pressure index) were put forward to analyze the metabolism of china. This paper could be the scientific basis for the sustainable development.
