Abstract: Understanding the dilemma of provincial CO₂ emissions and regional economy is critical for achieving low-carbon development of the power industry. This paper investigated the joint relationship and spatiotemporal distribution features of economy and CO₂ emissions in the power industry. First, the static temporal variation of regional GDP and provincial CO₂ emissions are explored in detail, based on the 2007-2017 data derived from the 'China Statistical Yearbook ' and 'China Electric Power Yearbook '. Second, the standard deviational ellipse method is adopted to investigate the dynamic spatiotemporal evolution characteristics of regional GDP and provincial CO₂ emissions. The results show that: 1) the joint characteristics of GDP and CO₂ emissions among 30 provinces exhibit four categories; 2) the spatiotemporal distribution of GDP maintains in northeast-southwest direction, while the distribution of CO₂ emissions shifts from northeast-southwest to east-west; 3) the mean centres of both are located in eastern China and move to the west. Based on the findings, the targeted emissions-control strategies for provincial power industry while maintaining stable regional economy are provided to achieve sustainability.

Keywords: CO₂ emissions; power industry; standard deviational ellipse; SDE; spatiotemporal analysis; temporal variation; China.
