Abstract
The comprehensive and accurate monitoring of coal power overcapacity is the key link and an important foundation for the prevention and control of overcapacity. The previous research fails to fully consider the impact of the industry correlation effect; making it difficult to reflect the state of overcapacity accurately. In this paper; we comprehensively consider the fundamentals; supply; demand; economic and environmental performance of the coal power industry and its upstream; downstream; competitive; and complementary industries to construct an index system for assessing coal power overcapacity risk. Besides; a new evaluation model based on a correlation-based feature selection-association rules-data envelopment analysis (CFS-ARs-DEA) integrated algorithm is proposed by using a data-driven model. The results show that from 2008 to 2017; the risk of coal power overcapacity in China presented a cyclical feature of “decline-rise-decline”, and the risk level has remained high in recent years. In addition to the impact of supply and demand; the environmental benefits and fundamentals of related industries also have a significant impact on coal power overcapacity. Therefore; it is necessary to monitor and govern coal power overcapacity from the overall perspective of the industrial network, and coordinate the advancement of environmental protection and overcapacity control.
Highlights
Electric power is the cornerstone of modern economic development
This study considered upstream and downstream industries, complementary industries, and alternative industries of the coal power industry in the scope of evaluation while constructing the initial index system of overcapacity risk assessment
We set the minimum support to 0.55 and the minimum confidence to 0.8 so as to retain the indicators that are strongly related to coal power overcapacity and judge the influencing direction of each indicator
Summary
Electric power is the cornerstone of modern economic development. Due to the limitation of energy resource endowment, the coal power industry has played a dominant role in China’s power system. China reached 1.01 billion kW, accounting for 53% of the total installed power capacity. As an important national basic energy industry, the industrial linkage of the coal power industry is very complex It has a direct impact on the upstream coal industry and the downstream capital-intensive industries such as steel and building materials, but it relates to the development of a national strategic new energy industry such as wind power and photovoltaic power generation. It has a significant, strategic position in the national economy. Coal power overcapacity has caused a series of problems such as tremendous waste of resources, serious environmental pollution, vicious market competition and may further increase the risk of economic fluctuation and affect the development of the national economy [3]
