China is the key player in the globalization era and is eliminating its intra-national trade barrier. This process will affect interprovincial CO 2 flows. This study recalculates interprovincial CO 2 flows in China by using the latest MRIO table and applies a gravity model to assess how market segmentation affects interprovincial CO 2 flows. Results show that the total volume of interprovincial embodied CO 2 flow did not increase excessively from 2007 to 2012, but the pattern of embodied CO 2 flow had changed a lot. Market segmentation significantly decreased the interprovincial embodied CO 2 flows in China and within its sub-regions. At interregional level, market segmentation’s negative effect was significant between Central and Western China. Other variables such as geographical distance showed a significant negative impact on interprovincial embodied CO 2 flow in China. On the basis of our results, we raise some relevant policies to deal with the environmental inequality caused by the decrease in market segmentation.
