Abstract.First, this paper delves into the intrinsic relationship between artificial intelligence (AI) and green transformation. Given the AI composition fallacy proposed by Fang Yi et al. (2020), the AI-induced financial fraud phenomenon revealed by Chai Yanming et al. (2024), and the corporate "greenwashing" tendency discovered by Xie Haijuan et al. (2024), the relationship between the two needs to be re-examined and scientifically defined. Second, this paper systematically analyzes the intrinsic mechanisms of AI and green transformation, explaining how they synergistically promote the development of …

Abstract.Under extreme heat conditions, street trees play a vital role in mitigating the urban street thermal environment. However, the relative contributions of their two- and three-dimensional greening structural characteristics remain insufficiently quantified. This study examined the differential effects of two- and three-dimensional greening indices on street thermal conditions. Mobile measurements were conducted on typical streets in Hangzhou during the summer of 2024 to collect daytime and nighttime meteorological data. Fisheye images and semantic segmentation were used to extract greening …

Abstract.The global shipping industry, as a core vehicle for international trade, is also a key area of carbon emissions. In recent years, the International Maritime Organization (IMO) has successively introduced policies such as amendments to Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL) and the Carbon Intensity Index (CII), explicitly requiring ships to reduce fuel consumption and greenhouse gas emissions. Ship energy efficiency management has become a core issue for sustainable operations for shipping companies. Traditional energy efficiency management …

Abstract.Aqueous zinc-ion batteries (AZIBs) have emerged as one of the most promising next-generation battery technologies for large-scale energy storage due to their high safety, low cost, and environmental friendliness. However, the practical application of zinc metal anodes faces severe challenges such as uncontrollable dendrite growth, hydrogen evolution reaction, corrosion, and passivation, which significantly restrict the cycling lifespan and Coulombic efficiency of AZIBs. Interface engineering, particularly the construction of artificial protective layers, is considered an effective strategy to …

Abstract.Focusing on the core relationship between the market-based allocation of data elements and urban-rural integration, this study explores both theoretical and empirical dimensions. Theoretically, data elements establish an enabling mechanism of "factor mobility-industrial synergy-income equilibrium" by breaking down urban-rural information barriers, optimizing resource allocation efficiency, and fostering new digital economy models: market-based data reduces the cost of factor circulation between urban and rural areas, driving the downward flow of production factors such as capital and …

Abstract.In order to stabilize domestic energy supply and reduce external dependence, the development of low-permeability tight oil reservoirs is the focus of oil and gas field exploration and development in China. Low permeability tight reservoirs usually have the characteristics of high reserves of geological exploration resources, poor physical properties and complex oil-water relationship. These characteristics restrict the development of low permeability tight reservoirs in China. In recent years, due to the maturity of drilling technology, development technology and stimulation technology, as …

Abstract.Alliance is the theoretical cornerstone of the traditional overseas military base regime. The alliance theory holds that the countries involved in overseas military bases should build a base system focusing on addressing traditional security threats based on a common enemy or a hypothetical enemy. With the continuous advancement of international socialization, the traditional overseas military base regime is difficult to cope with the emerging non-traditional security threats. Based on the examination of the overseas military base regime theories under the perspectives of realism, liberal …

Abstract.This article proposes a framework for understanding how spectators recognize cities in films by theorizing the relationship between city mindscape, city selection, and city recognition. Building on Kevin Lynch’s notion of the “image of the city” and research on cognitive mapping, the article distinguishes experience-based “city images” from media-based “city illusions,” and unifies them as a “city mindscape” – the composite mental landscape through which viewers perceive and remember urban space. On the production side, it introduces “city selection” to describe how filmmakers’ sample, weight, …

Abstract.Faced with the rapidly advancing trend of deep aging and the structural contradiction of a continuously shrinking labor supply in my country, the gradual delayed retirement policy has become a key institutional arrangement for alleviating labor shortages and enhancing the sustainability of the pension system. However, the economic effects of this policy do not evolve linearly, but rather form a cross-sectoral feedback mechanism between the labor market and the pension fund system, with complex impact paths, effect distributions, and policy costs. Existing research mostly explores the effects …

Abstract.This study takes the Yangtze River Delta urban agglomeration as a sample to evaluate the direct and spatial spillover effects of low-carbon industrial park pilot policies on urban carbon emissions. Theoretical analysis shows that policies suppress local carbon emissions through pathways such as technological progress, green investment, and industrial agglomeration; At the spatial level, there are spatial spillover characteristics that can be driven by technology diffusion to reduce emissions in the surrounding areas. The effectiveness of policies varies among cities and is influenced by …
