Abstract

Eco-industrial park(EIP), serves as a key strategy to reduce carbon emission in China. In this study, we employed input-output analysis(IOA) and ecological network analysis(ENA) to provide insights on how to mitigate carbon emission embodied in products or services for EIP from a system perspective. IOA is mainly used to construct carbon flow network among sectors and trace the source of embodied carbon emission to sectors. ENA is used to identify control/dependence relationship of sectors based on embodied carbon flow. The results show that "Manufacturing" is the main sector of embodied carbon emission, followed by "Electricity, steam, and hot water production" and "Mining". In terms of control/dependence relationship between sectors, "Construction" to "Manufacturing" is in a position of overwhelming dominance of pairwise control relationship with the control ratio of 0.91 while the control relationship between "Manufacturing" and "Transportation, storage, and postal services" with the control ratio of 0.03 is weak. Therefore, the amount of embodied carbon emission of each sector can serve as sectoral carbon reduction indicators and the control ratio provides useful information for systematic configuration of carbon. This work may contribute to low-carbon management for EIP.
