摘要：
Existing studies on the environmental Kuznets curve (EKC) neglect the inverse effect of pollution transfer from environmental regulation interactions on pollution reduction from a risk analysis perspective. Based on the regional differentiated attitudes on the environmental regulation reached in risk communication by the risk awareness biases of multiple interest groups, this article clarifies the causality between risk communication and risk transfer based on multistakeholder engagement processes; furthermore, the article incorporates the simultaneous action of the technological innovation effect and pollution risk transfer effect to construct a spatial environmental hyperbolic model with a bidirectional correlation between pollution emissions and economic growth in different regions. To verify our model, we select the pollution from agricultural watersheds in China as a sample to examine the two inverse effects. The results demonstrate that (1) agricultural watershed pollution and economic growth show an inverted U-shaped relation and a U-shaped relation in the local region and adjacent regions, respectively; (2) the pollution reduction assessment of the classical EKC model can be largely attributed to pollution risk transfer behavior; and (3) the turning point of the U-shaped curve appears earlier than that of the inverted U-shaped curve in the spatial hyperbola model. The findings suggest that stakeholders should consider the risk awareness bias caused by the imbalance of regional economic development and the scenarios that provide a "haven" for pollution risk transfer. Moreover, our study expands the theoretical connotation of the classical EKC hypothesis and is more suitable for pollution reduction scenarios in developing countries.
摘要：
Decarbonizing innovation plays a significant role in curbing carbon emissions, allowing a firm to meet governmental environmental regulations and gain a competitive edge. However, innovation uncertainty and technology spillovers deter a firm from doing so. This paper studies the issue of firms' decarbonizing innovation investment in a competing market under carbon emission regulation. We construct game-theoretic models of two competing supply chains, each consisting of a manufacturer and a retailer. Either manufacturer has the opportunity to invest in decarbonizing innovation, but she may fail in the end. According to the manufacturers' innovation investment decisions, several subcases with no investment, unilateral decarbonizing investment, and bilateral decarbonizing investment are explored. The results show that when both manufacturers have a strong absorbing capacity, neither invests in decarbonizing innovation; when they are weak in absorbing external technology, bilateral decarbonizing investment exists. The findings also reveal that unilateral decarboning investment dominates when the probability of innovation success is moderate. There is a case in which both manufacturers do not conduct decarbonizing investment, although the probability of innovation success is high. In addition, we also find that a retailer can make more profit if his upstream manufacturer invests in decarbonizing innovation than in the no-investment scenario. However, he is harmed by bilateral decarbonizing investment if his upstream manufacturer is weak in absorbing external knowledge relative to the case of unilateral decarbonizing investment. Our results elucidated how technology spillovers and the stochastic nature of innovation affect a manufacturer's decarbonizing innovation investment strategy in a competitive environment.

摘要：
The dependence of economic development on the metal resource is one of the challenges for developing countries. Given the enormous pressure of resource shortage in China, exploring the flow of metals between sectors is critical to achieve the Sustainable Development Goals. Based on the Chinese environmentally extended input-output (CEEIO) database from 1997 to 2017, the structural decomposition analysis (SDA) and the structural path analysis (SPA) models were combined to analyze the main driving factors and key paths of metal consumption in China. The results show that from 1997 to 2017, China's economic development and metal consumption presented states of weak decoupling and expansion coupling. Capital formation, consumption expansion, and export expansion were main drivers of metal consumption. Sectors such as metal smelting, construction, and other manufacturing products consumed a large amount of metal directly or provide intermediate products for other sectors. In the future, the upstream and downstream links of the industrial chain should be managed according to the key path, so as to optimize the structure of intermediate products and final demand and realize metal resources conservation from production to consumption.

摘要：
Carbon emission reduction is an important means of achieving climate policy goals. However, the literature has neglected consideration of the carbon emission reduction mechanism from the perspective of technology risk spillovers in international trade. To explore this mechanism, this paper expands the classical linear model of foreign trade technology risk spillovers into a nonlinear spatial Durbin model. We construct a novel technology risk spillover index to forecast the magnitude of carbon emissions in agricultural trade across different regions. To validate our model, we consider the dual connotation of the spatial diffusion of disembodied technology communication (DTC) to map the relationships between different geographic and economic regions that are adjacent. The results suggest that disembodied technology risk spillover could promote carbon emission reductions. Specifically, technology risk spillovers from agricultural trade reduce agricultural carbon emissions by 0.79–1.16% in the local region. Disembodied technology risk spillovers also reduce agricultural carbon emissions by 2.85–11.57% in geographically adjacent regions and 4.9% in economically adjacent regions. Based on these conclusions, this paper proposes improving the closed and backward situation of rural areas in China’s central and western regions, promoting the transition toward the high end of the global agricultural industry chain and developing productive agricultural services and the rural cultural tourism industry to expand rural employment channels and stabilize farmers’ income.

摘要：
The search for cost-effective, high-performance catalysts is crucial in catalytic co -pyrolysis. Different Fe-Mo@X catalysts (X = Al2O3, MgO) and reaction temperatures (600 degrees C, 700 degrees C, 800 degrees C, 900 degrees C) were tested to optimize hydrogen production and carbon quality while also exploring CNTs degradation performance. The results indicate that both catalyst type and operating parameters are highly dependent on the growth of carbon nanotubes and hydrogen. The FeMo@Al2O3 catalyst exhibits superior catalytic activity attributed to its more abundant mesoporous structure and higher specific surface area. Specifically, FeMo@Al2O3 achieved the highest yield of carbon nanotubes (84.42%) at 700 degrees C, and attained the maximum hydrogen yield (49.57%) at 900 degrees C. However, the CNTs synthesized from FeMo@MgO exhibited fewer defects, higher graphitization degree and purity (Raman and TPO). CNTs/MgO significantly enhanced the degradation efficiency of Clothianidin by virtue of their superior electron transport properties and chemical bonding between MgO and CNTs.
摘要：
How to identify the spatial spillover effects and pollution risk transfer in cross-border tourism remains a research gap in the literature. This study embeds disembodied technology communications into the classical environmental Kuznets curve to develop a new tourism-induced environmental spatial hyperbolic model to differentiate these two opposite effects. This study finds that the disembodied technology communications of cross-border tourism reduce the pollution emissions of destinations in both local and adjacent regions. The relationships between pollution emissions and the economic growth of destinations in local and adjacent areas present an inverted U-shaped curve and a U-shaped curve, respectively. These results highlight that governments should upgrade the quality of cross-border tourism consumption to induce disembodied technology communications from developed countries.
