Research on the pathway of digital technology to drive China's energy sector to achieve its carbon neutrality goal.

With global climate change looming large, there is an urgent need for China's energy sector to take steps towards carbon neutrality. This study aims to explore how digital technologies can contribute to the pathway for China's energy sector to achieve carbon neutrality. By analyzing carbon neutrality policies and digital technology applications, we propose a systematic pathway framework to guide China's energy sector in integrating digital technology to accelerate the pace of achieving carbon neutrality in the energy sector. We first review the current status of carbon emissions and carbon neutrality targets in China's energy sector, and in light of the development trend of modern digital technologies, we propose key application areas for digital technologies in realizing carbon neutrality in the energy sector. Second, we detail the specific applications and effects of digital technologies in energy supply side optimization, energy utilization efficiency improvement, carbon sink management, and smart grid construction. Through theoretical modeling and empirical analysis, we demonstrate the great potential of digital technologies in carbon emission reduction and carbon neutrality in the energy sector and reveal the key role of digital technologies in carbon-neutral pathways. Finally, we propose effective technology implementation measures and point out important challenges and solution paths for digital technologies in carbon-neutral practices. This study provides a scientific basis and guidance for China's energy sector to achieve carbon neutrality with the help of digital technologies and promotes the important steps towards carbon neutrality in China.

Assessment of green technology innovation on energy-environmental efficiency in China under the influence of environmental regulation considering spatial effects.

Enhancing energy-environmental efficiency (EEE) is crucial for achieving energy conservation and emission reduction goals. Investigating the mechanism through which green technology innovation (GTI) affects EEE and understanding the role of environmental regulation (ER) in this process provides a theoretical basis for efficient utilization of GTI and ER. This study employs a Dynamic Spatial Durbin Model and utilizes panel data from 2003 to 2017 for 30 Chinese provinces to examine the impact of GTI on EEE in the presence of ER. The empirical results reveal: (1) GTI has a U-shaped impact on EEE, primarily driven by SubGI. (2) GTI's influence on EEE is predominantly reflected in PTE, also stemming from SubGI. (3) The interaction term between ER and GTI is 0.0022, while the GTI coefficient is - 0.0741, and the GTI quadratic term coefficient is 0.0007, all statistically significant. This implies that ER mitigates the negative impact of GTI on EEE while strengthening its positive effect. These findings provide empirical evidence and policy insights for more effectively utilizing GTI and ER to enhance EEE and achieve energy conservation and emissions reduction goals.

Effects of Officials' Cross-Regional Redeployment on Regional Environmental Quality in China.

Cross-regional redeployment (or relocation) of government officials has a significant effect on the local economic development and environmental protection. Based on the panel data of 31 provinces (municipalities) in China from 2001 to 2016 and the environmental pollution index obtained by Entropy method, the dynamic panel regression model was applied to verify the relationship between the officials' cross-regional redeployment and environmental pollution. The results show that environmental pollution was positively correlated with officials' relocation and their tenure after the redeployment. As the officials' tenure increases to the critical value, the positive correlation between the official's tenure and environmental pollution would change. By measuring this threshold, we find that the average critical value for China was 5.14 years, which were the same as the average tenure of Chinese officials. Moreover, the result also illustrates the difference between central eastern China and western China, with the average threshold being 4.01 years and 5.89 years, respectively. In addition, the impact of officials' cross-regional redeployment on the environment would also be affected by the initial condition of the region. According to the result, the environmental governance within the central eastern regions was better than that in the western region. In the last part of this paper, we proposed measures and suggestions, such as changing the incentive policies of officials, perfecting the local policies and the cultivate and exchange system of cadres, as well as strengthen the power of social supervision, for the sake of facilitating the healthy and green development of the regional economy.
