Abstract
To address the issue of global warming, there is a trend towards low-carbon economies in world economic development. China’s rapid economic growth and high carbon energy structure contribute to its large carbon emissions. To achieve sustainable development, China must transform its industrial structure to conserve energy, reduce emissions, and adapt to climate change. This study measured the carbon entropy and carbon emission efficiency of 25 industries in the Beijing-Tianjin-Hebei region from 2000 to 2015 by building carbon entropy models and total factor industrial carbon emission efficiency evaluation models. The study showed that: (a) Priority development industries in the Beijing-Tianjin-Hebei region were expanding, the regional competitiveness of the moderate development industry was improving, and the proportion of restricted development industries had dropped significantly; (b) the spatial distribution of the three types of industries presented a pattern of concentric rings, with priority industries at the core, surrounded by moderate, then by restricted development industries; (c) the status of medium- and high-efficiency industries had improved, while the status of low-efficiency industries had decreased. Spatially, high- and low-efficiency industries were becoming concentrated, and medium-efficiency industries were becoming dispersed; (d) considering carbon entropy and carbon emission efficiency, the path of industrial structure transformation and upgrading and layout optimization in Beijing-Tianjin-Hebei region was proposed.
Highlights
Global climate change and the frequent occurrence of climate disasters are becoming major issues for humanity
We constructed an industrial carbon entropy and regional carbon entropy model based on electricity and carbon emission data by industry for the Beijing-TianjinHebei region from 2000 to 2015
We analyzed the evolutionary characteristics of the industrial structure of and the distribution of industries in the Beijing-Tianjin-Hebei region along the two dimensions of carbon entropy and carbon efficiency and discussed the path toward their optimization
Summary
Global climate change and the frequent occurrence of climate disasters are becoming major issues for humanity. Low-carbon economies have become a trend in world economic development to reduce greenhouse gas emissions. China’s rapid economic growth and the high degree of carbonization of its energy structure are responsible for its very high carbon emissions. These increased from 1.47 billion tons in 1980 to 10.4 billion tons in. 2013, accounting for 29% of total global emissions. Principally coal, are the main source of China’s energy production, accounting for about 90% of the total energy consumed. Industry is the largest consumer of energy by sector in China, and it is the main source of CO2 emissions. In 2007, President Hu Jintao made it clear at the APEC meeting that China should develop a low-carbon economy.
