Primary energy consumption structure and the influencing factors in China: an income decomposition and post-economic crisis era perspective.

China's coal-based energy structure makes its carbon peak and neutrality goals very challenging. As a result, optimizing the energy structure has become an important means, and researching its influencing factors and trends has become the foundation and prerequisite for policy formulation related to energy structure optimization. Especially after the severe economic crisis, the economic structure has undergone profound changes, and the impact of related factors on the energy structure has also changed. This study adopts regression methods considering heteroskedasticity and cross-section correlation to study the panel data of 30 provinces in China and obtains the changes in the relationship between fossil and non-fossil fuel consumption in different regions and their influencing factors after two global financial crises. Research results show that China's energy consumption tends to decouple from GDP. Income structure changes, especially trade changes, are important factors in influencing energy consumption and energy structure. The deviation between energy resource distribution and consumption distribution tends to increase. Regional heteroskedasticity is evident in the impact of urbanization development models, energy prices, and efficiency.
