Abstract

Understanding inter-industrial carbon emission transfers and their economic effect informs approaches to achieve emission reduction objectives and promote industrial economic development. This paper applies input-output theory to explore ways to optimize carbon emission transfers between industrial sectors. First, China's inter-industrial carbon emission imports and exports were measured for years 2002, 2005, 2007, and 2010. Next, the economic effects of inter-industrial carbon emission transfers were assessed. Finally, strategies to optimize the carbon emission transfer structure were proposed, with the goal of achieving a win-win between industrial carbon emission reduction and economic development. Key study conclusions are as follows. (1) Inter-industrial carbon emission imports and exports in China are significant, and are increasing each year. Traditional energy industries have high carbon emission imports; processing and manufacturing industries have high carbon emission exports; and most light industries have relatively low levels of both carbon emission imports and exports. (2) Carbon emission transfer imports or exports can promote industrial development; combining both imports and exports leads to variable economic effects within specific industries. (3) To achieve the dual goals of carbon emission reduction and economic development, four strategies are proposed to optimize carbon emission transfer structures in different industries.

4. Conclusions and Policy Implications

Concurrently promoting industrial economic development and realizing carbon emission reduction goals are vital for building a sustainable economy for China. Both factors serve as a solid foundation for industrial carbon emission transfer structures. Based on this, this study analyzed the total amount and dynamic change of China's industrial carbon emission transfers, explored the economic effect of industrial carbon emission transfers, and proposed strategies for optimizing carbon emission transfer structures. Three main conclusions and policy implications emerge from this work. (1) Carbon emission imports and exports already occur between different Chinese industries, with positive average annual growth rates and typical industrial characteristics. Specifically, traditional energy industries mainly have high CEI, while processing and manufacturing industries mainly have high CEE. Most light industries have relatively low levels of both carbon emission imports and exports. Therefore, government should not isolate industries when setting carbon emission reduction targets, and should consider carbon emission transfers (import and export) and their effects. Different characteristics of interindustrial carbon emission transfers also need to be considered, with the government implementing targeted and specific policies and measures.
