【 摘 要 】

The energy ecological footprint is an important theory and method for quantitative measurement of the coordinated development of the socio-economic-ecological environment. This research indicated the following: (1) the energy ecological footprints of China and the provinces showed significant linear increases (except Beijing). China's economy developed rapidly over 1999-2015, but the economic development had a high dependence on energy consumption, which induced an increase in the energy ecological footprint. Optimizing industrial structure and reducing energy consumption are effective ways to reduce the energy ecological footprint. (2) Forest land was the most important land use type for per capita energy ecological footprint capacity, accounting for 50% or more of the total. The energy ecological footprints of China and the provinces were mainly in a state of deficit, and only Sichuan, Qinghai, Guangxi, Shaanxi, Inner Mongolia and Xinjiang were in surplus. In addition, the ecological pressure in the eastern developed provinces was higher than in the central provinces, and the lowest pressure was in the west. (3) The energy ecological footprint of China and the provinces was mainly affected by the secondary industry output value, followed by population, total investment in fixed assets, and then the tertiary and primary industry output values. The results showed that reduction of industrial energy consumption is still the main issue for addressing carbon emissions in China.
