Abstract
In order to realize the synergistic optimization management of energy efficiency in the key energy-intensive industries of the Beijing-Tianjin-Hebei (Jing-Jin-Ji) region, this paper calculates the total factor energy efficiency (TFEE) of 27 industries in the Jing-Jin-Ji region. We discover that the manufacturing of raw chemical materials and chemical products, the smelting and processing of ferrous metals, and the production and supply of electric power and heat power are key industries, considering their economic output ratio, energy consumption ratio, and energy efficiency. Then, the Malmquist index is used to decompose the TFEE of key energy-intensive industries. The results show that the TFEE changes in the three major industries in the Jing-Jin-Ji region are caused by technological progress. Hebei has the highest total factor average energy efficiency in the production and supply of electric power and heat power industry, the main reason for this being the spillover effect from Beijing enterprises that have led to significant technological changes in Hebei. Due to similar technological advancements, Tianjin has the highest total factor average energy efficiency in the manufacturing of raw chemical materials and chemical products and the smelting and processing of ferrous metals. Therefore, the Jing-Jin-Ji region should work to increase its technological innovation and enhance its core competitiveness. We should optimize the allocation of resources in specific industries to improve the scale efficiency.
Highlights
The Jing-Jin-Ji region is part of China’s capital region and, as such, holds an important strategic position
We find that the production and supply of electric power and heat power, raw chemical materials and chemical products, smelting, and the processing of ferrous metals fall in the positive direction of the first principal component and the second principal component
This paper first uses the Data envelopment analysis (DEA) model to compare the average efficiency of the 27 industrial industries in Beijing, Tianjin, and Hebei from 2005 to 2015, and highlights three industries with considerable differences in their efficiency and energy consumption
Summary
The Jing-Jin-Ji region is part of China’s capital region and, as such, holds an important strategic position. At the end of 2015, the total population of the region exceeded 100 million, accounting for 8.11% of the total Chinese population. Total energy consumption reached 452.58 million tons of standard coal, accounting for 10.95% of the national total energy consumption, and the regional gross domestic product (GDP) reached 6935.889 billion Renminbi (RMB), accounting for 9.60% of China’s GDP. During the 12th Five Year Plan (FYP) period, the economy of the Jing-Jin-Ji region was strong, with an average GDP growth rate of 7.4%, while total energy consumption growth slowed down to an average growth rate of 0.68%. While the environment is deteriorating, the energy shortage in the Jing-Jin-Ji region is still unresolved. In 2015, primary energy production accounted for only 17.79% of total consumption. Faced with the dual challenges of energy shortage and environmental pollution, energy efficiency management
