Abstract

Based on the traditional concept of productivity and from the environmental protection perspective, this paper put forward the concept of ecological footprint productivity (EFP), analysed its connotation, probed into its computation steps, and measured China's EFP. Results showed that EFPs of cultivated land, forest land, grassland, water areas, and whole land have displayed a tendency of increasing since 2001, showing the development track of the right half of the U-shaped curve. By contrast, the EFPs of fossil energy land and building land had shown no apparent tendency. The EFP of all kinds of lands in China was estimated to show a continuous accelerated growth trend in the coming years.

Abstract

Based on the perspective of environmental protection, this paper adopts the Grey relationship analysis method to measure the relationship between ecological footprint of different land types, ecological footprint and economic growth. It is shown that there is strongest consistency between the grassland ecological footprint and the total ecological footprint. Changing tendency consistency between biological resource land's ecological footprint and the total ecological footprint is higher than that of energy resource land, the influence of energy resource land's ecological footprint on economic growth is stronger than that of biological resource land, and the building land's ecological footprint influences economic growth the most strongly.

Abstract

Burning coal, oil, natural gas and trees produce large amounts of carbon dioxide and methane. After these gases enter the atmosphere, the earth heats up and the carbon cycle becomes unbalanced, thereby resulting in global warming and deterioration of the ecological environment. To further analyse China’s carbon emissions, this study calculated China’s carbon emission productivity and predicted China’s carbon emission productivity level and growth rate for a certain period. Results show that in 1990-2016, China’s carbon emission productivity has continued to grow, and the actual GDP brought by unit carbon emissions has increased continuously. Moreover, China’s carbon emission productivity is expected to continuously increase. China can increase carbon emission productivity by improving energy efficiency, formulating and implementing carbon budget programs at the micro level, and implementing carbon taxes. Here, we expand the research perspective of carbon emissions, which has a certain reference value to further study China’s carbon emissions and protect the environment.
