This paper describes the market architecture of five regional carbon markets in China and carries out an empirical analysis of carbon spot price co-integration from 2014 to 2019. The evidence of co-integration at rank one reveals that these regional ETS pilots are not mutually exclusive of each other. The empirical results in this study show, for the long run, each percentage-point increase in Shanghai and Hubei pilot will cause a decrease of 0.37% and 0.78%, respectively, in the Guangdong price while Beijing and Shenzhen ETS do not enter the long-run relation significantly. In the short term, results suggest that any deviation from the equilibrium co-integrating relationships is mainly caused by changes within the Guangdong ETS. Given the critical stage of development of the national ETS, greater attention should be paid to exploring the relevance of carbon prices across pilots and eventually connecting the regional pilots to the national ETS.
