Assessing carbon storage dynamics and policy impacts
Mountainous regions play a vital role in global carbon sequestration, yet they are increasingly shaped by anthropogenic pressures and land-use changes. This study focuses on the Qinling Mountains in Shaanxi Province, China, to quantify historical land-use and carbon storage dynamics (1985–2020) and to project alternative futures to 2050. Using eight temporal snapshots of county-level data (n = 39), the study coupled the InVEST Carbon Storage and …
From Rare to Common
Since the early years of the 21st century, the city of Ruili has grown to be a major trade hub for Burmese jadeite on the China–Myanmar border. Starting from 2016 to 2017, Ruili's jadeite trade shifted heavily to online live streaming transactions through media platforms like Douyin, RedNote/Xiaohongshu, and Taobao/Tmall. This article showcases how the rise of a platform economy has fundamentally changed the settings of work and structures of jad…
Mapping Depression and Problematic Internet Use Symptoms in Chinese College Students
The rapidly growing rate of Internet use globally is associated with an increased risk of both depression and Problematic Internet Use (PIU) in young people. This study aimed to analyze the inter-relationships between depression and PIU among college students from the perspective of network analysis. A total of 6514 college students were recruited nationwide from September to December 2023 in China. Depression and PIU were assessed using the 9-it…
Decomposition and comparative analysis of urban-rural disparity in attitude towards advance care planning among Chinese adults
The findings suggest policymakers should enhance ACP education in rural areas to reduce disparities. Clinically, tailored ACP discussions and integration into routine care can improve acceptance, particularly in underserved regions
Decomposition and comparative analysis of differences in anxiety between urban and rural Chinese adults
The prevalence of anxiety was higher in rural than in urban Chinese adults. The government should identify urban-rural disparities' explanatory factors to target precise intervention strategies, thereby narrowing the mental health differences between rural and urban

This study investigates the significant effects of technostress on burnout and turnover intentions among university lecturers in China, emphasizing the urgent need to address this growing concern in higher education. By applying the Job Demands-Resources Model and the Transactional Theory of Stress, the research explores how the relentless pace of technological advancement exacerbates stress levels, leading to burnout and increased turnover inten…
Gender difference in prevalence and network structure of subclinical Hikikomori and depression among college students
Background: Subclinical Hikikomori and depression are common among college students, yet gender differences in their prevalence and interrelationships are under-explored. This study evaluated gender differences in prevalence and symptom networks of these disturbances. Methods: A large-scale, multi-center study was conducted across Xinjiang, Qinghai, and Guangdong provinces, China between September and December 2023. Subclinical Hikikomori and dep…
Three Faces of the State in Local Cyberspace Administrations
How does the Chinese party-state address the diverse and often conflicting challenges of internet governance? This study examines this question by analyzing the institutional design of municipal cyberspace administrations (MCAs), a key yet understudied group of local state actors. It brings together three often siloed state frameworks—the developmental state, the regulatory state, and the surveillance state—to theorize the roles MCAs are tasked w…
Understanding pedestrian crowd dynamics on ramps
The developmental party and the regulatory state in China's Internet governance
China's approach to Internet governance is increasingly perceived as a Party‐centric model, aligning the state under the Chinese Communist Party's (the Party) leadership. The division of labor between the Party and the state in the context of political centralization and Party centrality remains unclear. This study aims to address this knowledge gap by examining the Cyberspace Administration of China (CAC), a central player in Internet governance…
Reconceptualizing policy change in China
The conceptualization of policy change has been much discussed in democratic countries with a focus on formal legislation. However, in non-Western contexts, policies change in both formal and informal ways, and these informal mechanisms are challenging to observe. To fill this gap, this article uses the case of China’s policy process, where soft law policies play an increasingly important role in driving policy change. Drawing inspiration from le…
Enforcing Law Through Authoritarian Environmentalism? State and Non-State Actors in China's Environmental Public Interest Litigation
Numerous studies have examined China's authoritarian environmentalism, with a focus on policy-making and implementation. We argue that law enforcement should also be investigated as a crucial stage. Specifically, we examine environmental public interest litigation (EPIL) and analyse a novel dataset of 7010 EPIL court judgements from 2015 to 2020. We find that state prosecutors dominate EPIL activities, while the role of non-governmental organisat…
Socialising the European Semester? The limited influence of Danish social partners on EU policymaking
Many scholars have debated the role of social policy in the new economic governance after the financial crisis and the sovereign debt crisis. While some researchers argue that social policy continues to be subordinated in favour of the economic imperative, others observe a partial but progressive socialisation, both in terms of EU policy outputs (i.e. more focus on social policies) and the governance procedure (i.e. more participation of social a…
Soft law with a hard impact in local China
China’s hukou (household registration) system has undergone reforms aimed at addressing the large rural–urban divide. Importantly, it no longer distinguishes between agricultural and nonagricultural hukou. However, this reform is widely interpreted as being ‘soft’ and having little impact on reducing the rural–urban divide due to its symbolic nature. Still, this study takes a legal perspective and conceptualizes the reform as being in the form of…
Association Between Cancer Prevalence and Different Socioeconomic Strata in the US
Background Inequality in health outcomes in relation to Americans' socioeconomic status (SES) is rising. American Cancer Society depicts that the most common cancers are diagnosed in men and women in 2021. We aim to study socioeconomic inequalities in related cancers to investigate whether the cancer prevalence differs within the family income to poverty ratio (PIR). Methods The study investigated data from adults aged 20–85 years participated in…

Risk Culture and Covid-19 Protective Behaviors
The COVID-19 outbreak caused by the Severe Acute Respiratory Syndrome CoronaVirus type 2 (SARS-CoV-2) has spread across the world. However, our understanding of the public responses, in particular in adopting protective behaviors, has been limited. The current study aimed to determine the level of protective behaviors adopted by the residents in China and its association with their cultural attributes. A national cross-sectional online survey was…
Improved soft law implementation with national ownership
The Politics of Policy Reformulation
How do Chinese provincial governments reformulate the general central policies into implementable local policy outputs? How does this vary across provinces? Despite considerable research on policy implementation in China, strategies of policy reformulation remain understudied. To better understand these strategies, this article proposes a four-scenario typology: an innovative strategy, a defensive strategy, a conservative strategy, and a perfunct…
