Psychoactive drug use among athletes
Organised competitive sport represents a unique socio-cultural environment in which performance demands, social influences within sport and anti-doping frameworks shape athletes' substance use behaviours. In 2021, the World Anti-Doping Agency introduced a 'Substances of Abuse' category to address athletes' drug use outside the context of sport. Athletes may use psychoactive drugs, for example, to manage sports related pressure, stress and mental …

Co-evolution of private and public hospitals
Background: The global rise of private hospitals is crucial for achieving universal health coverage, yet the development of public and private hospitals remains uncoordinated. This study explores the co-evolution of private and public hospitals, focusing on their spatiotemporal disparities, geospatial interactions, and the social determinants under policy guidance. Methods: We used Sichuan province, China, as a case study and collected hospital-l…
Joint spatiotemporal evaluation of multiple healthcare resources
Background: Regional disparities in healthcare resource allocation across space and time present significant challenges to the global achievement of SDG 3, SDG 10, and SDG 11. To this end, we proposed a joint spatiotemporal evaluation framework to assess the synergistic efficiency of multiple healthcare resources. Methods: Using China as a case study, we analyzed data from 365 cities (2000-2021) on three key healthcare resource indicators: hospit…
Towards an infrastructure approach
The uneven distribution of healthcare resources has emerged as a prominent concern in healthy city development globally. However, extant research mainly follows an amenity approach that merely regards hospitals as passive spatial carriers of healthcare services and rarely considers them as an integral part of the urbanization processes, overlooking the interactive relation between hospitals and urbanization and their implications for the supply-s…

Association between 19 medication use and risk of common cancers
Background: Previous studies have yielded inconsistent results concerning drug use and the risk of cancers. We conducted a large-scale cross-sectional study and a two-sample Mendelian randomisation (MR) study to reveal the causal effect between the use of 19 medications and the risk of four common cancers (breast, lung, colorectal, and prostate). Methods: We obtained information on medication use and cancer diagnosis from National Health and Nutr…
Uneven primary healthcare supply of rural doctors and medical equipment in remote China
The findings suggest that the PHC inequalities are increasingly a result of joint social, economic, and institutional forces in recent years, underlining the increased complexity of the PHC resource allocation mechanism. Therefore, we claim the necessity to incorporate a broader understanding of community orientation in PHC delivery, particularly the interdisciplinary knowledge of the spatial lens of community, to support its sustainable developm…

Does the development of green finance in Chinese provinces reduce carbon emissions to a certain extent? This study selects panel data of various provinces and cities in China from 2003 to 2019. Based on the Hansen threshold regression model, an empirical analysis is conducted with economic growth and industrial structure as threshold variables to tes…
From Keeping a Low Profile to Striving for Achievement
Since 2012, some scholars, both Chinese and foreign, have argued that China's assertive foreign policy is doomed to fail. Nevertheless, after examining China's foreign relations in the last two years, this paper finds that China has experienced improved relations rather than deteriorating ones. In comparison with the strategy of keeping a low profile (KLP), the strategy of striving for achievement (SFA) shows more efficiency in shaping a favorabl…

The secondary circuit of capital and the making of the suburban property boom in postcrisis Chinese cities
Drawing on Harvey's capital switching thesis, this study develops a heterodox approach from a crucial perspective to China's post-2016 nationwide property boom. We trace the roots of this suburban property boom to the 2008 global financial crisis and investigate its nature as a solution to China's post-2008 overaccumulation crisis. By scrutinising the serial policies formed at the central level, we unpack the continuous endeavours of the state in…
Housing affordability, subsidized lending and cross-city variation in the performance of China’s housing provident fund program
This study examines the cross-city variation in the performance of China’s Housing Provident Fund (HPF) program, a collective saving scheme that provides subsidized lending to support participants’ home purchases. It finds that while the program as a whole is limited in both participation and benefit provision, the level of HPF activities has differed across localities. Panel-data analysis of HPF lending in seven cities reveals that local housing…

Equitable exit strategy is required
The impact of social inequalities on people’s vulnerability to COVID-19, especially by non-pharmaceutical interventions (NPIs), has been widely discussed.1 2 However, recent resurgence of community outbreaks in Hong Kong clearly warns us that, without taking social inequalities into account when planning exit strategies, the pandemic may stage a comeback and spread even more rampantly. Hong Kong is currently undergoing the ‘third wave’ of local o…
Toward Accessibility-Based Planning
Problem, research strategy, and findings A growing consensus has formed among planners, especially planning scholars, that promoting accessibility is a major policy goal. However, efforts to promote accessibility-based planning face a conceptual impediment: a common assumption that equates the benefits of accessibility to travel cost savings (TCS). Starting from this assumption, many researchers have interpreted the absence of TCS (e.g., savings …
