Using the Tapio-Z decoupling model to evaluate the decoupling status of China's CO2 emissions at provincial level and its dynamic trend

This paper deduces the connection between Per capita GDP (g) and the Tapio decoupling index (D) as a formula. Then, a two-dimensional decoupling model (Tapio-Z decoupling model) and decoupling analysis framework is constructed based on a Cartesian coordinate system with Per capita GDP (g) as horizontal axis and Tapio decoupling index (D) as vertical axis. Finally, the decoupling status of China's CO2 emissions at provincial level and its dynamic...
