Policy modeling consistency analysis during energy crises: Evidence from China's coal power policy

The coal power crisis threatens global energy security and hinders the achievement of the sustainable development goals. Regarding energy security, quantitative analysis of the coal power policy is required for the sustainable development of the coal power industry. Therefore, by using the methods of text mining and content analysis and taking three large-scale coal power crisis series of policies in China as examples, this paper constructs a PMC index model of coal power policy and analyzes the evolution of coal power policy system from the perspective of crisis management. The results show that: (1) China's coal power policy is characterized by diversification of policy areas and policy instruments, but there are problems such as poor coordination between sectors and insufficient supply-demand early warning. (2) According to the different periods of the coal power crisis, the gestation period mainly involves the instruments of target planning and regulatory constraint, which can play a guiding role but may also have the reverse effect due to the shortage of power supply. During the explosive period, price and multisubject governance mechanisms are used to intervene in the crisis. During the processing period, the government mainly strengthens the supply-oriented policy to meet the structural adjustment of energy industry demand. (3) Throughout the three coal power crises, the supply policy instruments and multisubject governance mechanisms have gradually become the primary means to address the coal power crisis. Finally, suggestions are put forward for the implementation of the coal power policy from multiple perspectives.
