Carbon dioxide emissions, economic growth, industrial structure, and technical efficiency: Empirical evidence from Ghana, Senegal, and Morocco on the causal dynamics
“…Thus, in order to achieve economic development and environmental protection, the structure of energy and industry as well as energy efficiency, need to be improved further. The evolution of energy intensity had more weight in determining the ICE reduction for Jiangsu in the last years, and it was also applicable to China's other regions and other developing countries [1,5,8,16,21]. Although energy intensity in Jiangsu was at a lower level in China, there is still room to improve in comparison with other developed countries.…”

“…This study combined them to investigate the decoupling path of Jiangsu. The effort and decoupling index indicated the weight of each factor and the degree to 1 Due to the data limit of energy consumption of the mining of other minerals, the sector was not analyzed. Table 1 shows the values of different decoupling indexes and their contributions to carbon emissions.…”

“…The continuous growth in energy consumption, particularly the fossil fuels, has threatened the environment by increasing the emissions of greenhouse gases [1] and exacerbating the scarcity of natural resources, such as water and land [2,3]. According to the IPCC (intergovernmental panel on climate change) reports, atmospheric CO 2 has increased by 2.0 ppm per year since 2001, climbing to 390.5 ppm in 2011 [4].…”

“…Normally, the carbon emissions are heavy when there is a large ratio of secondary industry in the industrial structure (Kofi Adom et al. ). Also, the coefficient of trade openness is always positive and statistically significant.…”
SummaryThis article employs panel data from 28 Chinese provinces over the period 1999-2011 to analyze the effects of industrial waste reuse (IWR) on carbon emissions. The extant studies mainly consider the direct effects that individual firms garner from IWR while ignoring other possible indirect effects in a more macroscopic context. Considering this research void, this article examines the potential indirect effects of IWR on carbon emissions through economic growth as the mediator. The results show that the direct effect of IWR on carbon emissions is negative and significant, but the positive indirect effect, through economic growth, is present. From the perspective of total effect, IWR is beneficial for both economic growth and carbon emission reduction (CER). However, the benefits for CER are mitigated when the economy is less developed, because the emission reduction could be compromised through the indirect effect of economic growth. Nevertheless, the indirect effect on compensating carbon emission is decreased with an increase in the economic growth. When the growth reaches a higher level, the indirect effect of IWR will alter to contribute to CER. The turning point in China is around 7,000 to 9,000 renminbi gross domestic product (GDP) per capita in 1999 constant price.
“…The optimization of the industrial structure and the transformation process directly influence the stability of national economic development [1][2][3][4]. Industrial transformation is the essential demand for economic prosperity, especially for less developed countries [5].…”
China has been stressing the needs of promoting regional sustainable development through industrial transformation. In the northwest region of China, which is faced with both urgent socioeconomic development and fragile ecological conditions, with water scarcity being one of the major characters, the relationship between industrial transformation and water use efficiency ought to be investigated. This paper conducted an empirical analysis of industry transformation's impact on water use efficiency by using the Input-output analysis. First, we compiled an extended Input-output table with water use account; Second, the input-output analysis model was built based on the extended Input-output table; Then, a counterfactual experiment was performed to document the water use efficiency caused by industrial transformation; Finally, water use efficiency of different sectors in both northwest region of China as a whole and its five provinces were calculated. The results show that water use efficiency of northwest region of China is improved by optimizing industrial structure. Also, sectors with low water use efficiency but huge improvement potential were found out. Then policy implications for regional sustainable development and water resources management are provided at the end of the article.
