EKC test study on the relationship between carbon dioxide emission and regional economic growth.

With the rapid development of regional economy, energy consumption and carbon dioxide emission increase sharply. This study examines the relationship between carbon dioxide emissions and regional economic growth. Based on the mean value decomposition method of double logarithm, the model was built to identify the key indexes affecting the decomposition, and the carbon emission formula was calculated to obtain the regional carbon dioxide emission. Based on the actual data, the kuznets curve model is established to represent the relationship between CO2 emission and regional economic growth in logarithm form. The unit root test, co-integration test and granger causality test are carried out for the correlation sequences in the kuznets curve model in order to realize the research on the relationship between CO2 emission and regional economic growth. This paper discusses the relationship between carbon dioxide emission and regional economic growth through an example. It shows that the relationship between carbon dioxide emission and regional economic growth is inversely u-shaped, and there is a kuznets curve between the two. According to the result of empirical analysis, the paper puts forward some suggestions to reduce energy consumption and improve energy efficiency, which is helpful to improve social and economic structure and promote social and economic development.
