This paper constructs global trade competition networks, portraying the evolution of the multi-scale global competition patterns and structure from global to regional to national levels, and exploring the influencing factors. The results show that: 1) From 2000 to 2019, global aerospace trade competition intensity and density increased, with aircraft and core subsystems exhibiting polarized competition, non-core subsystems characterized by large scale and high density. The outbreak of COVID-19 caused a sharp decline in competition. 2) Trade competition between Europe and North America, as well as within Europe, is particularly intense, with a trend to transfer towards Asia, especially in the engine segment. Asian countries exhibit diverse competition relationships with low intensity but rapid growth. 3) Global competition is dominated by a few countries with entrenched hierarchies. The US occupies the absolute core, forming a stable "hub-and-spoke" structure in supply chain competition. The second-tier France and Germany hold advantages in final product competition and are moving towards efficient competition in aircraft segment. China has grown rapidly in the parts competition but faces significant competitive pressure. 4) The trade breadth and trade control capacity exhibit positive effects on trade competition. Intense trade competition tends to take place between closer countries with similar economic levels and amicable political relations, as well as between countries with large technology gaps and firm gaps in the aerospace sector.

Grounded in Lefebvre's theory of spatial production and drawing on new materialism and assemblage theory, this study adopts a qualitative approach to examine the production of everyday labor space of traditional marine aquaculture fishermen on Guanglu Island, Changhai County, Dalian. Viewing space as the outcome of continuous interactions between human and nonhuman elements, the research reveals how natural forces, cultured organisms, labor tools, and temporary workers collectively construct and constantly reshape the fishermen's working space. Methodologically, this study combines field observation with semi-structured interviews. The findings indicate that fishermen's labor space manifests in three interrelated dimensions. First, the physical space exhibits dynamic assemblage characteristics. Fishermen's work extends across the sea-land boundary, where diverse elements—humans, tools, cultured species, and natural environments—interact to form flexible, adaptive, and constantly changing spatial configurations. Second, the relational space embodies multiple tensions. The rigid demands of the marine environment and cultured species impose structural constraints, while the intervention of market and technological forces further intensifies these pressures. Within this unequal framework, fishermen rely on limited agency to negotiate contradictions and maintain production. Third, the subjective space reflects both physical and psychological predicaments. Long-term exposure to harsh environments leads to chronic pain and physical exhaustion, while repetitive work and economic uncertainty give rise to emotional numbness and a sense of helplessness.

Regional digital innovation cooperation has emerged as a key driver for high-quality urban development. This study analyzes digital technology joint patent data from 41 prefecture-level and above cities in the Yangtze River Delta urban agglomeration over the period 2011—2022. Utilizing Social Network Analysis and fuzzy-set Qualitative Comparative Analysis, the research unveils the spatial structural characteristics and evolutionary trends of the digital innovation network, and explores the configurational paths for enhancing intercity cross-sector innovation cooperation. The findings indicate that the digital innovation network evolves from a simple and sparse structure to one that is complex and dense, with the "small-world" property gradually manifesting. Moreover, cohesive subgroups undergo a phased transition from multi-core decentralization through structural reorganization to coordinated evolution. The spatial pattern of the network is characterized by a polycentric structure led by core cities, with a pronounced east-west spatial differentiation. High-level cross-sector innovation cooperation depends not only on a robust economic foundation but also on well-developed digital infrastructure. Three driving paths are identified: the "city subject" dominant, the "digital environment-city subject" balanced, the "digital environment-city subject" robust.

As US-China rivalry shifts focus to the "Indo-Pacific," the US's "Indo-Pacific Arc" disrupts regional stability. This paper applies "territorial trap" theory to develop a geopolitical influence model integrated with the wedge strategy. Analyzing spatiotemporal changesin US and Chinese influence within the "Indo-Pacific Strategy" region provides recommendations for China. Findings: 1) Overall US-China influence evolved through "low volatility" (2011—2015), "medium convergence" (2016—2018), and "high stability" (2019—2021) phases, with China's influence growing 11.2% annually; 2) Country-level analysis shows three power evolution types: stable, reversal, fluctuation; 3) Geopolitical categorization reveals US advantage (Australia, Philippines, Japan, New Zealand), China advantage (Indonesia, Malaysia, Vietnam, Brunei), and balanced influence (India, South Korea, Thailand, Singapore); 4) Influence model factors align with wedge strategy methods. Strategically, China should prioritize reward wedges in advantage zones and mixed coercive/reward strategies elsewhere.

Farmers are vital for preserving traditional villages and promoting tourism, and their livelihoods deserve priority in sustainable development. This study, based on two villages in Suzhou's Wuzhong District, assesses livelihood capital and stability, applies a coupling coordination model to evaluate their relationship, and uses regression to identify key factors. Findings show: 1)Tourism-related livelihood strategies enhance livelihood capital. Tourism-exclusive households rank highest in livelihood capital, followed by tourismoriented, labor-oriented, balanced-income, and agriculture-oriented ones. 2) Livelihood stability and coupling coordination have an inverted U-shaped link with tourism involvement. 3) Different livelihood capitals affect coordination differently but generally have positive impacts. 4) Strengthening financial and social capital is vital for enhancing farmers' sustainable capacity.

In recent years, the phenomenon of city walking has emerged in several Chinese cities, reflecting the lifestyle pursuits of urban youth. This provides a new context for exploring the relationship between the individual self and place in everyday life. Inspired by a humanistic geographical perspective, this study uses participatory observation and semi-structured interviews to gather data. The findings are as follows: First, through interaction with the locale, the everyday life spaces of city walkers become objectified. Secondly, the process of urban objectification brought about by city walking is accompanied by a process of self-objectification, where the "emergingself" and the "obscured self" coexist and transform into each other.Lastly, as both the self and the city are objectified, they enter a dynamic state of being simultaneously connected and detached, and city walking provides a way to potentially bridge these elements in daily life. These findings reveal interactions between the self and the world, bridging theoretical perspectives such as David Seamon's"Triad of Environmental Experience" and Yi-Fu Tuan's "Urban-Self" concepts, and also contribute to theoretical scope of domestic everyday life geography.

"Local revitalization" refers to emphasizing the importance of "local" based on the regional characteristics of traditional villages, highlighting regional differences, and integrating the local reality to achieve protection and development tailored to the specific context of the village. To enhance the local relevance and suitability of traditional village protection and development, local revitalization is an important approach for promoting the dynamic development of traditional villages, as well as a significant initiative in response to the rural revitalization call. Based on grounded theory and in-depth field surveys, this study uses three different types of traditional villages in the Loess Plateau hilly region of central Gansu as examples to explore the local relevance and adaptability in the protection, development, and revitalization practices of traditional villages, aiming to provide guidance on the revitalization direction for villages in the region. The research findings indicate that: 1) The five practical paths—culture, industry, population, landscape, and mechanisms—align with the actual development needs of traditional villages in the Loess Plateau hilly region and reflect the basic demands of the local population. Among them, population and industry are the core factors for promoting the dynamic development of traditional villages in the Loess Plateau hilly region, while culture and landscape are key to revitalization, and mechanisms ensure the success of the revitalization process. 2) By constructing five local revitalization paths—"culture-industry-population-landscape-mechanisms"—the goal is to promote the dynamic development of traditional villages in the Loess Plateau hilly region. These include: local culture responding to the revitalization of Loess cultural characteristics; local industry responding to the revitalization of village economic development; local population responding to the revitalization of villagers as the main agents; local landscape responding to the revitalization of settlements and ecological environments; and local mechanisms responding to the revitalization of governance mechanisms. (3) Through empirical analysis of different types of villages, five local revitalization paths centered on "culture-industry-population-landscape-mechanism" were formed. These five paths not only align with the real-world context of protecting and developing three different types of traditional villages but also represent the future development direction of traditional villages in the region. The aim is to enhance the local relevance and suitability of traditional village protection and development in the Loess Plateau hilly region, jointly promoting the dynamic development of traditional villages.
