“…British Petroleum (BP’s) (2022) report reveals that over the span of more than four decades, China’s consumption of coal has risen by an impressive 6.28-fold, and its carbon emissions have surged by a remarkable 6.42-fold. China’s carbon emissions accounted for 31.1% of the global total in 2021 (Li et al, 2021), and in 2022, the emissions decreased by 23 million tons, reaching a total of 11.477 billion tons (Zhao et al, 2023). The Chinese ISI released 574,000 tons of SO 2 , 1,114,000 tons of NOx, and 897,000 tons of particulate matter in 2020 (Zhu et al, 2022).…”

In the last 20 years, China’s steel production has proliferated, leading to increased environmental damage by releasing 574,000 tons of sulfur dioxide (SO2), 1,114,000 tons of nitrogen oxide (NOx), and 897,000 tons of particulate matter (PM) in 2020; therefore, the country is now struggling to reduce carbon emissions and tackle climate change because of the conflicting demands of economic growth and environmental protection. Given the global emphasis on decarbonization and sustainable production, China has prioritized achieving peak carbon emissions of 30% by 2030 and carbon neutrality by 2060. Likewise, China’s steel industry is progressing toward attaining the maximum carbon dioxide (CO2) emissions by 2025. This study reveals that despite a 321 Mt increase in global energy-related CO2 emissions in 2022, CO2 emissions in China experienced a decline of 230 Mt during the same period. Notwithstanding enacting several pertinent statutes and directives, China’s iron and steel sector has not advanced substantially.

“…Pathway analysis is a statistical analysis method used to study complex causal relationships between variables. This method was first proposed by geneticist Sewall Wright and is mainly used in the fields of social sciences, biology, and economics [30,31]. The fundamental concept of pathway analysis is to visually represent the links between various factors by categorizing them into direct and indirect effects.…”

Given the threats to international energy security and the restructuring of energy sources in various countries, China faces the dual challenge of achieving the goals of carbon peaking and carbon neutrality. To promote a reduction in carbon emissions and enhance carbon productivity, it is crucial to innovate renewable energy technology for long-term, low-carbon transformational development. This paper identifies the key factors that affect carbon productivity through pathway analysis and quantitatively examines the direct and spatial spillover impacts of technological advancements in renewable energy using the spatial Durbin model. Finally, this study verifies the pathways through which innovations affect carbon productivity by combining them with the spatial mediation model. The results indicate that innovations in renewable energy technologies significantly enhance carbon productivity. The indirect effects of regional spillover are even more pronounced.

“…The Yangtze River Delta urban agglomeration is the most densely populated and economically developed region in China, as well as being a group of towns with the highest level of urbanization and the highest urban density [30]. However, the intensive exploitation of land resources has greatly increased the ecological risk in cities in the future [31], and the construction of the Shanghai-Nanjing-Hangzhou industrial bases has also made the contradiction between urbanization and environmental quality in the Yangtze River Delta increasingly acute [32]. Zhang et al conducted a study on the coordination between development intensity and habitat quality in the Yangtze River Delta integrated region and found that the development intensity index of the Yangtze River Delta integrated region increased from 0.3833 in 2005 to 0.7833 in 2020, and the habitat quality decreased from 0.5049 in 2005 to 0.4937, indicating that the contradiction between development intensity and habitat quality will further intensify, and the integration of eco-green and high-quality development will face a greater challenge [33].…”

Twenty-six cities in the Yangtze River Delta urban agglomeration were taken as the research object, and this study comprehensively evaluated urbanization quality and ecological resilience from 2005 to 2020. On this basis, the spatiotemporal evolution characteristics and main influencing factors of the coupling relationship between urbanization and ecological resilience were systematically explored using a coupling coordination model and panel Tobit regression model. The results can be summarized as follows: (1) from 2005 to 2020, the quality of urbanization in the Yangtze River Delta urban agglomeration continued to grow, the level of ecological resilience grew slowly and fluctuated, and the development among municipalities tended to be balanced. (2) The overall coupling coordination degree of urbanization and ecological resilience showed a continuous increasing trend, and the coupling coordination type changed from basic coupling coordination to good coupling coordination. The number of cities with lagging urbanization quality decreased significantly; spatially, the gap in the coupling coordination degree between municipalities narrowed, and the cities with good coupling gradually clustered. (3) The results of the panel Tobit regression showed that the differences in the spatial evolution of coupling coordination mainly resulted from the interaction of drivers such as real utilized foreign capital, per capita GDP, carbon emission intensity, the proportion of science and technology expenditure to fiscal expenditure, the ratio of per capita disposable income of urban and rural residents, fixed asset investment in municipal utility construction, and the index of ecological land area ratio. In the future, the coupling coordination degree of urbanization and ecological resilience should be improved based on the type of coupling coordination according to local conditions, and the seven influencing factors should be carefully examined to accelerate the high-quality integrated development of the Yangtze River Delta.
