    The age of digital geo-economy is coming: A discussion on analytical framework and research approach of digital geoeconomy
    Teng MA, Yijie LI, Yuejing GE, Zhiding HU
    2026, 35(4): 1-16.  DOI: 10.3969/j.issn.1004-9479.2026.04.20250068

    The global digital revolution, widely acknowledged as the Fourth Industrial Revolution, is continuously deepening against the backdrop of pressing issues. Major global powers are increasingly intensifying their exploration and competition within the digital realm, marking the advent of the digital geoeconomics era. This paper provides a systematic analysis of the emerging field of digital geoeconomic space. Firstly, it elucidates the concept of digital geoeconomics based on the power and spatial interaction logic inherent in traditional geopolitics, as well as the interactions among nation-states centering on "data" as a new means of production. Secondly, it examines key topics within digital geoeconomics, including competition over digital sovereignty and data elements at the level of digital rights, the growing significance of technology giants and core digital technologies, and China's "Digital Silk Road" initiative. Finally, building on a theoretical exploration of the entanglement between geopolitics and geo-economy, along with an analysis of digital power and digital space, this paper proposes a three-dimensional analytical framework for digital geoeconomics, comprising material space, flow space, and discursive space. It analyzes the spatial pattern of the digital geo-economy through three concrete dimensions: digital infrastructure, digitally mediated geo-economic relations, and digital geo-economic discourse, thereby offering insights into geography's engagement with digital space and suggesting pathways for future research.

    Geopolitical shift in global marine boundary governance
    Renfeng MA, Liangliang LI, Xianjun LIANG
    2026, 35(4): 17-31.  DOI: 10.3969/j.issn.1004-9479.2026.04.20250303

    Since the beginning of the 21st century, the global restructuring of maritime rights and interests has given rise to challenges such as resource competition, control over strategic passages, and overlapping claims, all of which point to a transformation in the logic of national maritime boundary delimitation. This transformation is mainly reflected in the following aspects: ① The logic of national maritime boundary delimitation is shifting from traditional bases such as international jurisprudence, the equidistance principle, and the natural prolongation of the continental shelf, towards the diverse claims of coastal states in terms of marine resources, economy, and space. ② The complete chain of evidence constructed by means such as deep-sea exploration, remote sensing (RS), and automatic identification systems (AIS) is replacing the traditional logic of international maritime delimitation and becoming the dominant factor supporting historic sovereignty claims and continental shelf delimitation rules. Based on the above transformation, it is imperative to break the deadlock in maritime delimitation from the following aspects: revise and supplement the relevant principles of the United Nations Convention on the Law of the Sea (UNCLOS) by incorporating standardized technical systems such as deep-sea exploration and real-time monitoring; build an open and inclusive multilateral cooperation platform to promote the joint governance of coastal states. At the same time, it is essential to promote the integration of maritime law and emerging marine technologies. And ultimately achieve the coupling of the above-mentioned technologies with negotiation platforms, steering the global ocean governance system towards a more transparent, verifiable, and sustainable direction.

    Progress in overseas research on rural entrepreneurship from the geographic perspective and its inspiration
    Peipei CHEN, Min ZHANG, Enyu CHANG, Linshen JIAO
    2026, 35(4): 32-47.  DOI: 10.3969/j.issn.1004-9479.2026.04.20241015

    Following the multifunctional transition in the process of rural development, rural entrepreneurship has become a significant engine for rural revitalization. The potential that rural areas offer for entrepreneurship has been largely underestimated. This paper reviews the overseas research on rural entrepreneurship. The main findings are as follows. First, key factors influencing rural entrepreneurship include the material spatial characteristics and resource endowments of specific rural localities, local social features and entrepreneurial cultural atmosphere, as well as rural remoteness and accessibility. Second, the interaction mechanisms between entrepreneurial activities and the social, institutional, and spatial contexts of rural areas determine the development trajectory of rural entrepreneurship. Third, rural entrepreneurship not only creates economic value but also holds equally significant social value. Finally, based on both the theoretical advancements and limitations in international rural entrepreneurship research and the developmental needs of China's rural entrepreneurship, this study proposes implications for Chinese rural entrepreneurship research from three perspectives: ① It suggests that future research on rural entrepreneurship should construct a multi-scale research framework suitable for China's rural context, considering the significant disparities that exist in entrepreneurial ecosystems due to regional heterogeneity. ② Future research should explore the interactive mechanisms between entrepreneurial activities and rural localities from a multidimensional dynamic perspective, with particular attention to the dynamic evolution of entrepreneurial embeddedness throughout the venture lifecycle. ③ A comprehensive socioeconomic effect analysis of rural entrepreneurship is needed, which assesses the socioeconomic value of rural entrepreneurship across micro-level rural actors, meso-level rural communities, and macro-level rural revitalization. Through drawing upon western conceptual frameworks, theoretical systems, and research advancements in rural entrepreneurship while grounding our work in China's institutional contexts such as urban-rural duality and rural revitalization, this paper aims to promote the localized innovation of rural entrepreneurship theories. Moreover, through constructing culturally sensitive analytical frameworks, we not only enhance the explanatory power for domestic issues but also contribute Chinese perspectives to global rural entrepreneurship research.

    Zhong GUAN, Xiangdong ZHU, Canfei HE
    2026, 35(4): 48-59.  DOI: 10.3969/j.issn.1004-9479.2026.04.20241110
    Abstract ( )   HTML ( )   PDF (1064KB) ( )  

    As a driver of global energy transition, the photovoltaic (PV) industry's trade pattern is significantly influenced by carbon reduction policies across nations. Based on China's PV export data from 2009 to 2020, this study incorporates the carbon emission reduction of destination countries into the analytical framework and employs a panel data econometric model to explore its impact on China's PV export. The findings reveal that: ① Most China's PV exports deriving from coastal provinces, with the Yangtze River Delta region accounting for 68% of total exports; ② Carbon emission reduction in destination countries stimulate PV market demand, thereby increasing their imports of Chinese PV products; ③ The positive impact of carbon emission reduction on China's PV exports intensified after the Paris Agreement but weakened following the U.S.-China trade war; ④ Carbon emission reduction exert a stronger positive effect on PV exports from provinces with high levels of industrial agglomeration and strong policy support; ⑤ Destination countries with robust PV industrial agglomeration relying less on Chinese PV; ⑥ Countries that have established carbon trading markets or imposed trade barriers on Chinese PV products have increased their imports from China under the pressure of carbon reduction targets. Our research indicates that the impact of destination countries' carbon emission reduction should be incorporated into the optimization of PV industry and trade policies.

    National digital development and corporate environmental protection: Inverted U‑shaped relationship, institutional moderation, and cross‑country heterogeneity
    Lihe HUANG
    2026, 35(4): 60-74.  DOI: 10.3969/j.issn.1004-9479.2026.04.20250149
    Abstract ( )   HTML ( )   PDF (995KB) ( )  

    With the wave of digitalization sweeping the world, its impact on environmental sustainable development has attracted extensive attention from the academic community. However, there is a lack of empirical evidence to systematically examine the impact of digitalization on corporate environmental protection from the perspective of national differences. Based on the panel data of 5 015 enterprises in 47 countries from 2008 to 2019, this study uses a fixed-effect model to investigate the relationship between national digital development and corporate environmental protection performance. The results show that there is an inverted U-shaped relationship between national digital development and enterprise environmental protection, that is, digitalization is conducive to enterprise environmental protection in the early stage, but has a negative impact after exceeding the threshold. The quality of national institutions has a positive moderating effect on this relationship, and a high-quality institutional environment can delay the negative impact of digitalization on the environment. These relationships differ in the three dimensions of environmental innovation, emissions management, and resource use, and are different between developed and developing countries. This study enriches the theoretical research on the effects of digital environment and provides an empirical basis for countries to formulate digital environmental governance policies.

    Research on the impact of residential segregation on residents' health in the United States: Causes, characteristics and mechanisms
    Yanrong QIU, Kaihuai LIAO, Tianlan FU, Gengzhi HUANG
    2026, 35(4): 75-90.  DOI: 10.3969/j.issn.1004-9479.2026.04.20250115
    Abstract ( )   HTML ( )   PDF (948KB) ( )  

    Urban residents' health is a critical issue in China's social development. Residential segregation and its impact on health have received widespread attention. Based on the U.S. context, this paper reviews the causes of residential segregation, its association with residents' health, and the path mechanisms that affect health. The study finds: ① Three forces—structural oppression, cultural identity, and individual agency—jointly shape the spatial patterns of residential segregation, with institutional exclusion based on structural racism being the primary cause of residential segregation in the United States. ② Residential segregation is strongly associated with health inequality, and it is positively related to adverse health outcomes such as infectious diseases, chronic diseases, suboptimal maternal and infant health, cancer diagnosis, disease mortality, and mental illness among the segregated groups. ③ The adverse effects of residential segregation on health are the result of the interaction of multiple environmental factors such as social environment, food environment, healthcare environment, built environment and employment environment, which include three path mechanisms: the spatial accumulation of risk exposure, the mediating transmission of chronic psychological stress, and the intergenerational solidification of systemic deprivation. By examining health inequalities stemming from residential segregation in the United States, this study can provide important insights for promoting the construction of a healthy city in China.

    An analysis of American think tanks' cognition of China's participation in Middle East affairs
    Wang HE
    2026, 35(4): 91-103.  DOI: 10.3969/j.issn.1004-9479.2026.04.20241063
    Abstract ( )   HTML ( )   PDF (560KB) ( )  

    In the context of Sino-US strategic competition, studying the perception of US think tanks on China's participation in Middle East affairs is helpful to judge the dynamics and trends of US government development. The study selects 24 representative research documents from eight mainstream American think tanks as research samples for literature analysis, sorting out the main cognition and characteristics of American think tanks on China's intentions, actual situation, impact on the United States, and how to deal with China's growing influence in the Middle East. The results show that US think tanks' perception of China's participation in the Middle East is mainly negative, which is affected by the situation of Sino-US strategic competition and their own ideological attributes. However, due to the complexity and long-term nature of Middle East affairs, US think tanks also advocate cooperation between China and the United States in the Middle East. my country should view the views of US think tanks dialectically, strengthen communication and exchanges, and accelerate the construction of a Middle East discourse system with Chinese characteristics. At the same time, it should continue to play a greater role in the security and development of the Middle East and eliminate the impact of negative perceptions with practical actions.

    Nan LI, Zhucheng WANG
    2026, 35(4): 104-119.  DOI: 10.3969/j.issn.1004-9479.2026.04.20240702
    Abstract ( )   HTML ( )   PDF (1571KB) ( )  

    The high-quality development of coastal port cities is an important component of high-quality development, and it also urgently needs to inject new development momentum. Used panel data from China's five major coastal port city clusters from 2003 to 2022 and combined with models such as Markov chain, exploratory spatial data analysis and Dagum Gini coefficient to explore the spatio-temporal evolution of their high-quality development and identified the driving factors of high-quality development by using a spatiotemporal geographically weighted regression model. The results show that: ① The overall level of high-quality development is gradually increasing, the Southeast coastal area, Yangtze River Delta and Pearl River Delta regions are relatively leading, and there is a high possibility for coastal port cities to maintain their current development levels in the future; ② The overall high-quality development shows a significant positive spatial correlation. The main reason for spatial imbalance is regional differences and overlapping between regions; ③ There is significant spatiotemporal heterogeneity among the driving factors, with the level of information technology, population size, fiscal dependence, economic concentration, modernization of industrial structure and port construction scale having a promoting effect, while the total freight volume has a constraining effect.

    Analysis of the spatial and temporal impact of the built environment on shared bicycle riding density:Taking Shenzhen as an example
    Na LI, Tianqun WANG
    2026, 35(4): 153-166.  DOI: 10.3969/j.issn.1004-9479.2026.04.20240750
    Abstract ( )   HTML ( )   PDF (1768KB) ( )  

    As a green mode of transportation, the shared bicycles' spatiotemporal nonstationarity of ridership across different areas is believed to be influenced by the built environment. This study focused on the area where the distribution of shared bicycles is relatively concentrated in Shenzhen, examining the relationship between the built environment and shared bicycle ridership using multisource urban big data. It selected independent variables based on the "5Ds" dimensions of the built environment and compares the performance of the Geographically Weighted Regression (GWR) model with the Geographically and Temporally Weighted Regression (GTWR)model. The analysis considered both temporal and spatial dimensions to assess the impact of the built environment on shared bicycle ridership density. The results indicate that:①the GTWR model provides a better fit than the traditional GWR model. ②Temporally, shared bicycle ridership is influenced by morning and evening commutes, while spatially, it aligns with the characteristics of urban center activities, exhibiting significant clustering. ③In terms of built environment indicators, the increasing of the building density, road network density, catering POI density and traffic POI density significantly promote shared bicycle use, particularly during peak hours on weekdays and in central urban areas. Conversely, the POI diversity, the distance from the city center and the nearest distance to the bus station have a suppressive effect on shared bicycle usage. The results can provide more precise guidance for future rational transportation strategies or sustainable urban planning.

    Fluid identity in places: A case study of the "Married Women Returning to Their Hometown" in Hakka Village
    Zhen LI, Hong ZHU, Xiaoru XIE
    2026, 35(4): 167-181.  DOI: 10.3969/j.issn.1004-9479.2026.04.20240816
    Abstract ( )   HTML ( )   PDF (1280KB) ( )  

    Folk festivals serve as significant avenues for studying local cultures by constructing local images, constructing place cultural identities, and fostering local economic development. This study, taking the "Married Women Returning to Their Hometown" event in Beiyin Hakka Village, Paitan Town, Guangzhou City as a case, explores how newly created rural folk activities reinforce the place identity of these women. The event unfolds in various forms, such as the Pi Xiu dance performance (a Hakka dance), carrying bamboo baskets (a traditional Hakka practice), ancestor worship, singing Hakka folk songs, and sharing reunion dinners. The emotional connections and place cultural identity forged during the event re-establish emotional bonds between the married women and their hometown, strengthening their cultural confidence. Solidarity, support, and historical recollections awaken their collective identity, deepening their local identity. Additionally, improved economic conditions enhance the quality and participation of the event, fostering a stronger sense of identity and support for the hometown's economic development. Furthermore, including local villagers, clan brothers, andvisitors, provided differing levels of support and recognition to the married women during the event. As a result, their sense of place identity was deepened from the familial level to the entire village, achieving an expansion from personal families to a broader sense of collective belonging. Theoretically, the research has expanded the theoretical framework concerning the relationship between newly created rural folk festival and place identity, contributing to a deeper understanding of how such customs construct place identity. Practically, it offers positive guidance on utilizing folk festival to enhance cultural integration and place identity among different ethnic groups. Well-organized and leveraged, newly created folk festival can serve as a soft governance tool that advocates cultural identity, internalizes ethical norms, and fosters social unity, thereby holding practical value for further promoting rural cultural revitalization. Lastly, it merits further contemplation whether the construction of place identity in clan villages possesses unique characteristics. This research provides practical cases and theoretical support for cross-disciplinary areas such as rural community governance, cultural construction among diverse ethnic groups, and enhancing women's rights and self-awareness.

    The dimension construction and characteristic analysis of Shanghai's nighttime tourism perceived image based on low-light image enhancement method
    Lingyan LI, Haoyu AN, Baoshun SHI, Chunzi ZHU, Wanting YANG
    2026, 35(4): 182-198.  DOI: 10.3969/j.issn.1004-9479.2026.04.20240691
    Abstract ( )   HTML ( )   PDF (1763KB) ( )  

    Nighttime tourism photos serve as important carriers to reflect tourists' preferences. Taking Shanghai as an example, this study established a nighttime tourism image analysis model based on the low-light enhancement method KinD to restore photo content. Utilizing Deepsentibank to mine images, and through content analysis, social network analysis and spatial analysis, the study explored the characteristics of nighttime tourism perceived image, aiming to grasp tourists' authentic attitudes and emotional preferences. The results show that: ① KinD can effectively improve the recognition accuracy of nighttime tourism photos and accurately restore photo content details. ② Utilizing the cognitive-affective model, the dimensions of Shanghai's nighttime tourism perceived image are constructed into eight main-images and twenty-two sub-images. Cognitive images show the highest proportion of nighttime scene creation. In affective images, positive emotions account for more than half. The dimensions of Shanghai's nighttime tourism perceived image exhibit characteristics such as coexistence of hardware and software elements, integration of old and new elements, overall positive evaluation with localized deficiencies, and subjective-objective deviations among elements. ③ The cognitive image network exhibits a "multi-core, multi-edge" structure. Tourists preferred image combinations that the interaction between nighttime scene creation and nighttime entertainment experience elements, the mutual reflection between nighttime scenes creation, and the collision and interweaving of urban nightscape scenery and nighttime scene creation dimensions. The affective image network is dominated by low-intensity positive emotions. The image of nighttime scene creation is more strongly associated with positive emotions, while negative emotions primarily emerge in urban nightscape scenery. ④ The spatial structure of Shanghai's nighttime tourism perceived image exhibits a characteristic of "local concentration and multi-point dispersion". The overall spatial distribution is uneven, and tourists' perceptual focus is concentrated in Shanghai's core tourism areas. This study contributes to refining the research approach for nighttime tourism photos and broadening the application scope of interdisciplinary methods, aiming to provide decision-making references for the optimization development of nighttime tourism.
