Summary: This study evaluates the green growth efficiency of oil and gas resource-based cities in China using the DEA-SBM model and Malmquist-Luenberger index. The results show that the static efficiency of green growth in most cities is low, but the eastern region has higher efficiency and improved environment. Moreover, more than half of the cities have a dynamic efficiency value of green growth greater than 1, indicating a positive development trend for green growth.

Summary: This study analyzes the city water resource green efficiency (CWRGE) of 108 cities in the Yangtze River Economic Belt using the Super-SBM model. The results show that the overall CWRGE has not yet reached an effective level, with a trend of first decreasing and then increasing, and overall improvement. There are significant gaps in CWRGE among cities of different scales, with downstream cities having the highest efficiency. The level of economic development, industrial scale, and water usage structure significantly affect the CWRGE in the Yangtze River Economic Belt.

Summary: This paper focuses on the green logistics efficiency of China's provincial logistics industry and explores its development using quantitative models and analysis tools. The results show that China's green logistics efficiency is relatively low but has an upward trend, with higher levels in the eastern regions and lower levels in the western regions. The level of green technology is a key factor affecting overall development.

Summary: This study examines the impact of environmental regulation (ER) on green innovation efficiency (GIE) in prefecture-level cities in China from a spatial correlation perspective. The empirical results show that GIE first declined and then increased, with a significant spatial spillover effect of ER on GIE showing a U-shaped impact. Shorter official tenure and lower enterprises' profitability weakened the impact of ER on GIE. The government should strengthen regional cooperation, improve public environmental supervision, and formulate stringent but differentiated ER based on local conditions.

Summary: The high-quality development of the Yellow River Basin has become a national strategy, requiring resource-based cities to undergo a high-quality transformation. Using the super-efficiency SBM-DEA and panel Tobit regression models, along with night light data, the analysis examines the spatiotemporal evolution characteristics and main driving factors of carbon emission efficiency in the Yellow River Basin. The findings show that carbon emissions continue to grow, with high-emitting cities concentrated in the Jiziwan basin. Additionally, carbon emission efficiency follows a U-shaped curve over time and is relatively high in the upper and lower reaches of the basin.

Summary: Ecological efficiency, as a representation of the quality of a region's development, is important in meeting human needs. This study examines the eco-efficiency in 11 cities of Zhejiang Province, China and finds that the overall eco-efficiency is steadily rising, but there are regional imbalances. Factors such as the share of tertiary industry, the number of scientific researchers, and the foreign trade dependence positively affect the improvement of eco-efficiency, while highway transportation mileage has a negative impact.

Summary: This paper empirically studies the impact of environmental information disclosure on green energy efficiency in China. The results show that environmental information disclosure has a significant positive effect on improving green energy efficiency and also has spatial spillover effects. The study finds that the average green energy efficiency in the environmental information disclosure cities is higher in the East and lower in the West. The findings also reveal a significant spatial correlation and agglomeration pattern between environmental information disclosure and green energy efficiency. Furthermore, environmental information disclosure can significantly improve green energy efficiency in the region and surrounding areas, with a more significant impact in the eastern region.

Summary: The study reveals regional differences in atmospheric environmental efficiency in China, with the eastern region performing best and the central region performing worst, and these differences increase year by year. Technical progress is the dominant factor influencing atmospheric environmental efficiency, while economic development level and pollution control input also have significant impacts on atmospheric environmental efficiency.

Summary: This study investigates the urban compactness and energy efficiency in China and finds that there is a certain gap in the coordinated development between the two. Although compactness has increased in some cities, there is still room for improvement overall, while energy efficiency shows a continuous upward trend with potential for further improvement. The coordination degree between the two is gradually increasing, although compactness lags behind energy efficiency. The findings of this research provide policy recommendations that are crucial for promoting urbanization and energy transformation in China.

Summary: Using an extended super-SBM model, we examined the impact of green credit on the green investment efficiency of 588 listed Chinese green companies from 2009 to 2019. The results showed that green credit can improve a firm's green investment efficiency, especially for state-owned enterprises and those in high-growth industries. Further analysis revealed that corporate governance, innovations, and financial constraints moderate the positive effect of green credit on green investment efficiency. This study provides novel evidence highlighting the importance of green credit in promoting corporate green investment efficiency in China.
