Compared with the impact of listed corporates' environment, social responsibility, and corporate governance (ESG) on financing and market value, considerably less attention is paid to the role of ESG performance in improving environmental quality in China. However, exploring the environmental motivation of listed corporates' ESG engagement is vital for shareholder protection and corporate strategic development under state–business interactions. Thus, we study the relationship between state–business interactions and air pollution from the perspective of ESG using the dataset of Chinese listed corporates. The results demonstrate that the state–business collusion interactions increase air pollution by hindering the fulfillment of ESG. Meanwhile, this impact of heavy pollution corporates is higher than that of industrial corporates. However, the deleterious relationship might be largely improved when state–business interactions are "clean." Finally, we observe that ESG mediates the relationship between state–business interactions and pollutants. [ABSTRACT FROM AUTHOR]

The energy sector matters the sustainable development directly and is sensitive to climate change. A few empirical studies concentrate on how climate change influences firm performance. Climate change brings higher production costs and lower efficiency on the supply side and leads to beneficial sale performance and improves profit. However, it is ambiguous to the relationship of supply–demand and revenue‐cost levels, and their change is not consistent. Using panel data of 99 China‐listed firms active in the energy sector over the period 2000–2020, this study aims to identify the causal relation between climate change and the profitability of energy firms while controlling for firm‐specific and energy market‐related factors. The quantile regression results show that temperature deviation (TDEV) positively impacts the profitability of energy firms, and this impact varies at different quantiles of the profitability distribution. These findings remain unchanged by four robustness checks. Moreover, mechanism results indicate that revenue and cost have different interaction effects on the causal relation. The findings of this study can provide forward‐thinking expectations and assess climatic adaptation and risks, particularly inspired stakeholder engagements. [ABSTRACT FROM AUTHOR]

The process of international specialization has evolved from "intra-industry" to "intra-product," resulting in the establishment of value chains that traverse all participating nations. However, it might lead to the "lock-in low-value" effect of global value chains (GVCs) and the consequential "pollution shelter" effect, which have both hindered the green transformation of the economy. Rather than solely focusing on promoting participation in GVCs, this paper seeks to expand its purview to include national value chains (NVCs) based on endogenous resource integration, with a focus on constructing and nurturing NVCs to enhance regional green economy performance index (GEPI). We find that improving NVCs positions can increase regional GEPI, while GVCs and NVCs participation inhibit GEPI. Moreover, the impact of GVCs and NVCs positions and participation on GEPI presents significant and spatiotemporal heterogeneities. Finally, the mechanism analysis demonstrates that GVCs positions increase human capital investment and NVCs positions increase the rationalization of the industrial structure, promoting green economy performance. Meanwhile, China's GVCs and NVCs participation increase the industrial proportion, which is not conducive to improving green economy performance. • Quantifying China's international trade's environmental effects through value chain specialization. • NVCs positions can strengthen the effect of the green economy performance. • Participation in value chain displays an adverse impact on green economy performance. • Investigating the heterogeneities of green economy performance along GVCs and NVCs position and participation. • Exploring channels through which of value chain specialization affect green economy performance.

Non-fossil energy increases the non-dispatchability of power system, requiring fossil-based technologies to provide back-up capacity as dispatchable source. In a coal-based economy like China, it is coal-fired units that act as back-up capacity. This paper shows that increase of non-fossil energy generation is associated with higher heat rates of coal-fired units, which can be explained by the decreased operating hours for dispatching. This side-effect is sizeable, accounting for 13% of carbon mitigation from non-fossil energy. The extra fuel cost is estimated to be 10.9 billion US dollars. This paper thus calls attention to alternative technologies, such as large-scale storage, as dispatchable source. • Dispatching policy ensures the exogeneity of non-fossil energy in regression. • Discussing how non-fossil energy increases the heat rate of coal-fired units. • Calling attention to the essential role of coal-fired units as dispatchable source. • Highlighting the indirect cost of integrating non-fossil energy for power system.

The continuous entry of new firms and exit of old ones might have substantial effects on productivity of energy supply. Since China is the world's largest energy producer, productivity of energy supply in China is a significant issue, which affects sustainability. As a technical application, this paper investigates the productivity and dynamic changes of Chinese coal mining firms. We find that the total factor productivity (TFP) growth of coal supply in China is largely lagging behind the growth rate of coal production. The entry and exit of non-state-owned enterprise (non-SOE) partially provide explanation for the dynamic change of aggregate TFP. Specifically, non-state owned entrants induced by the coal price boom after 2003, which had negative effects on TFP of energy supply, while the exit of non-SOEs had positive effects. Furthermore, there is regional heterogeneity concerning the effects of entry and exit on energy supply productivity. More entrants induced by coal price boom are concentrated in non-main production region (non-MPR), while more exits are located in MPR due to the government's enforcement. This provides explanation for the phenomena that productivity of energy supply in MPR gradually surpasses that in non-MPR. We also anticipate our paper to enhance understanding on the energy supply-side, which might further help us make informed decisions on energy planning and environmental policies.

The progresses of marine meteorology studies achieved in China during the four year period from 1999 to 2002 are summarized in six directions: air-sea flux, marine meteorology in high latitudes, marine disasters, connection between ocean and weather/climate in China, remote sensing applications and new methodologies in marine meteorology. Compared to the previous ones, these studies adopted much more first-hand datasets, and more scientific issues were involved. As an exciting remark, there were so many contributions done by the young scientists. A brief statement about the research strategy of marine meteorology in China for the coming years is also given.
