A growing appreciation of the potential benefits of experimentation to tame the complexities of urban transformation has led to an increase in related research activity. Building on a "practice-to-policy" experimentation-based framework, this paper investigates the adaptive policymaking process for urban regeneration in Shenzhen since the 2000s. It finds that "explorative experimentation" is used to identify a general direction in the absence of a clear route for the policy process, while "generative experimentation" is sequentially dedicated to specific issues for the improvement of the entire policy package within a particular reform. We argue that understanding the successive roles or hybrid functions of these two types of experiment adds new insights to the development rationales for Shenzhen's urban regeneration and provides inspiration for an experimental model of urban governance. Governments and policymakers can benefit from the experimentation-based approach, as presented in the Shenzhen case, to pursue policy innovation embedded in local contexts. [ABSTRACT FROM AUTHOR]

In China, the equal accessibility of social infrastructure, especially public housing and healthcare, has become a prominent concern in solving the problems of rapid but uneven growth-oriented urbanization in the post-reform era. However, few studies have focused on the accessibility of various healthcare resources to different types of public housing using different transport modes. Utilizing Internet map services, this study first calculated the travel time from talent, economically affordable, and public rental housing to hospitals using three transport modes--walking, public transport, and driving--in Shenzhen, China. Subsequently, the optimized twostep floating catchment area method (2SFCA) was employed to comprehensively evaluate the accessibility of healthcare resources to public housing and explore differences in healthcare accessibility among different populations. The results reveal that: (1) Public housing is located far away from healthcare resources, with 15% of public housing unable to access AAA hospitals within 30 minutes by car, and only 10% able to access ordinary hospitals within 15 minutes. (2) Accessibility of healthcare resources to public housing exhibits spatial heterogeneity, gradually declining from special to non-special economic zones. (3) Talent housing experiences the best accessibility, followed by affordable and public rental housing. (4) Public transportation and walking exhibit greater spatial variation in accessibility than driving. Theoretically, the current public housing accessibility in Shenzhen reflects the common problems of public housing accessibility throughout the country. In the process of promoting the equal accessibility of basic public services, focus on its accessibility should be emphasized. This study proposes an optimized 2SFCA by introducing a Gaussian distance decay function, establishing a multilevel search radius, considering supply and demand-side competition effects, and using real-time traffic big data. Our methodological framework simultaneously considers differences among various types of public housing, hospitals with different service capacities, and diverse travel modes. This provides a new research perspective for a comprehensive and thorough understanding of the equal accessibility of basic public services. [ABSTRACT FROM AUTHOR]

Since the reform and opening-up, the ecological environment of the coastline of Shenzhen has been under pressure from high-intensity human exploitation activities. Additionally, the structure, type, and length of the coastline has undergone significant changes. Studying the changes of the Shenzhen coastline over the past 40 years is helpful to reveal its spatial and temporal evolutionary processes and driving mechanisms to provide a reference for the protection and utilization of coastline resources. This study screened 16 scenes of the Shenzhen regional Landsat remote sensing images from 1979 to 2019, and performed a coastline extraction using Remote Sensing (RS) and Geographic Information System (GIS) methods to ensure alignment, accuracy, and extraction precision to meet the research requirements. Based on four coastline evaluation indexes (End Point Rates, Linear Regression Rates, Coastline-type Diversity Index, and Comprehensive Index of Coastline Utilization), the spatiotemporal characteristics of the coastline length, structure, types, and rate of change were analyzed to explore the factors driving the spatio-temporal evolution of the Shenzhen coastline. The results found that over the past 40 years, (1) the length of the Shenzhen coastline has experienced a continuously increasing trend, with a total increase of 41.52 km, and an average annual growth of 1.04 km. All the natural coastlines within the coastal area of Shenzhen decreased significantly to varying degrees, with a total decrease of 56.61%, while the proportion of artificial coastlines increased rapidly. (2) The change in coastline type in Shenzhen is mainly from the early muddy and sandy coastline to the farming reclamation and engineering construction coastline, i.e., the transition from natural to artificial shore. Among them, coastline length increased the most from 1979 to 1988. The most drastic coastline change was observed from 1979 to 1994, and the peak period of land reclamation was from 1994 to 2008. After 2008, Shenzhen coastline development gradually entered a sustainable and rational stage. (3) The spatial vicissitudes of the Shenzhen coastline have progressed through the stages of initiation, acceleration, and rational restriction. Areas with significant coastline expansion were located in Bao'an International Airport, Qianhai Cooperation Zone, Shenzhen Bay of Houhai, Yantian District, and near Longqi Bay. The change in the west coast of Shenzhen is more drastic than that of the east coast. The maximum rate of change (EPR) on the west coast reaches 422.19 m/a, which occurred during the Shekou Peninsula seaward extension period from 2004 to 2008. The EPR on the east coast reached the highest level of 449.65 m/a during the development and construction of Yantian Port from 1994 to 1998; and (4) the Shenzhen coastline change is a dynamic and a continuous process of change. Human activities, special zone policies, and natural factors were the main driving forces of the coastline changes. The special zone policy is the core driving force for Shenzhen's population expansion, urban sprawl, and the fundamental reason for the reduction in natural coastlines and the growth of artificial coastlines. This study provides important guidance for future sustainable urban development in Shenzhen. [ABSTRACT FROM AUTHOR]

With the acceleration of urbanization and promotion of the integrated strategy of the Greater Bay Area (GBA), the number of migrants in the Pearl River Delta (PRD) has increased dramatically. With "Healthy China 2030" presented, mental health of migrants is of great significant to China's New-type Urbanization. Additionally, with the profound reforms in society and economy, the measurement and action mechanism of migrants' mental health deserve in-depth exploration. Using the data collected from the China Labor-force Dynamics Survey (CLDS) in 2016 for Guangzhou and Shenzhen and using the linear regression model, the study explored the effects of working environment, social interaction, and physical health on migrants' mental health. The second focus of this study was on the difference between migrants' mental health in Guangzhou and Shenzhen City through the empirical statistical results. Our empirical findings suggest that: 1) Migrants' mental health is significantly affected by working environment, social interaction, and physical health; among them, work satisfaction, lower work stress, community confidence, and self-rated health all have a positive impact on the mental health of migrants. Additionally, higher income is commonly associated with mental health. 2) For Guangzhou City, work stress, community confidence, self-rated health, drinking, exercise, and treatment have distinct impacts on the mental health of migrants. 3) For Shenzhen City, only work satisfaction, work stress, selfrated health, and treatment have distinct impacts on the mental health of migrants. In summary, this study used CLDS data from 609 migrants in 2016 to provide a more comprehensive picture of their working environment, social interaction, physical health, and mental health. Moreover, this study is a comparative analysis of migrants' mental health between Guangzhou and Shenzhen, which indicates that migrants' mental health in Guangzhou is mainly affected by work environment, social interaction, and physiological health; however, the work environment and physiological health play a significant role in migrants' mental health in Shenzhen. Based on the empirical findings, we call for further policymakers and practitioners to focus on both spatiality and heterogeneity in planning and governance. Municipal governments should consider the rationalization of land use and functional transformation to create harmonious social networks and promote migrants to better integrate into urban society. In addition, Guangzhou should increase and optimize leisure facilities and green space to strengthen the social interaction between migrants and locals, while it is of great importance to improve the working environment in Shenzhen and take measures to reduce migrants' working pressure by enhancing the safety and comfort of the working environment.

The cultural, economic, institutional, and social connotations of "diversified connection space" are used as the spatial basis in urban micro-location and firm location selection. This study examines the evolution of firm location selection from the perspective of "diversified linkages", incorporates "diversified linkages" in urban micro-location with the firm location evolution model based on the assumption of "cost sharing," and discusses urban micro-locations, diversified linkages, and enterprise location selection. The selection of a firm's location is determined not only by economic factors and market mechanisms, but also through the interaction of location-specific economics with social and geographical factors that manifest themselves as a common set of rules and entrenched social and cultural practices. For example, behavioral norms and social relationships among entrepreneurs that permeate the internal economic relations and production activities of enterprises can influence the location selection of these enterprises. Using the findings of empirical research on information technology enterprises, such as those based in Shenzhen, micro-enterprises, and micro-locations in urban space, we examined the factors that influence the selection of a firm's location using Ordinary Least Squares (OLS) regression, Geographically Weighted Regression (GWR), and Semi-parametric GWR (SGWR) analyses. The results showed that spatial selection of enterprises in urban micro-locations occurred through a combination of bottom-up market mechanisms and top-down policies, and that the influence of traditional factors were more significant. Although land use and function categories were significant factors, the robustness of other variables was not strong. In addition, the results of GWR and SGWR analyses were better than those of OLS regression, indicating significant spatial heterogeneity in urban micro-locations. The spatial diversity and heterogeneity of space were also verified, to a certain extent, by differences between local and global variables. Therefore, "diversified connection space" attributes the focus of an urban micro-location to spatial elements and the spatial mechanism of firm location selection, such that economic, geographical, and social spaces are compatible. It is also influenced by a combination of economic, geographical, institutional, and social factors. This process is not only affected by economic factors, such as factor endowment and economic function (of land use) and its market role, but also by planning, policy, traffic conditions, and other "cost sharing" factors. Consequently, the meaning and usage of urban micro-location and location theory have expanded. [ABSTRACT FROM AUTHOR]

Based on the observation data of 30 automatic weather stations in Shenzhen, climate change trends in Shenzhen in the past 10 years are analyzed. The results are shown as follows. (1) The average air temperature grows by a rate of about 1.47 ℃/(10 a) in Shenzhen from 2011 to 2020, significantly higher than that in the previous decade, suggesting that climate warming has not eased yet. (2) Due to the effect of urbanization, daily temperature ranges show a decreasing trend over much of Shenzhen, while an abnormal upward trend is witnessed for a few limited areas. (3) Surface wind speeds in Shenzhen generally show a decreasing trend, which is even faster in developed areas. (4) Average relative humidity in Shenzhen shows an increasing trend from 2011 to 2020, with the maximum annual increase at 1.33%. (5) According to the statistics of extreme rainfall data at different spans of time in the districts of Shenzhen, the growth rates of extreme rainfall and annual total precipitation are large in undeveloped areas, with the highest growth rate at 42.41 mm/a, while the maximum value of moving precipitation with duration less than 6 hours shows a decreasing trend in other areas. (6) By using long-time series data of multiple automatic weather stations, a more detailed analysis can be done of the local climate change characteristics for Shenzhen, which is a useful supplement to analyses based on national basic stations data and helpful for deeper exploration of the relationship between urbanization and climate change.

This paper studied the characteristics and patterns of lightning in Shenzhen under the influence of tropical cyclones. Based on the historical data of tropical cyclones (TCs) in the Northwest Pacific Ocean from 2012 to 2019, the TCs within 1 000 km to the Shenzhen Station were screened out and grouped according to their intensity. Moreover, using the lightning and temperature observational data in Shenzhen during the same period, the present study analyzed the characteristics of lightning induced by TCs with different intensity at various distances and azimuths in Shenzhen. It is found that the inter-annual variation of lightning in Shenzhen under the influence of TCs is very large, and the lightning activity in Shenzhen is the most active in July and August in a year. Most of the distances where TCs have a great impact on lightning activities in Shenzhen are beyond 400 km, indicating that Shenzhen is in the outer rainband of TCs. Generally, during typhoon season, tropical depression, tropical storm, and super tropical storm are more likely to cause lightning in Shenzhen, especially when the tropical storm is over Fujian Province, 400 ～600 km away from Shenzhen. This article can provide scientific and technological reference for TCs disasters prevention and mitigation in Shenzhen. [ABSTRACT FROM AUTHOR]

This paper presents 'shared projects' and the 'symbiotic' relations they engender to capture accounts of state and society actors collaborating to turn individual constraints into collective opportunities for pursuing urban experiments which are institutionally-shaped but also institution-shaping. The concepts are developed through a sequential and recursive comparison – that is, a 'comparative conversation'– between a case of urban village upgrading in Shenzhen and Community Land Trust Development in London. The paper uses a pragmatist approach to capitalist transformation as a starting point for comparison between these supposedly 'incomparable' cases. I build both heterogeneous and generalisable accounts of the pathways and progressive potential of collaborations on shared projects by recursively composing analytical proximities across the cases and their contexts of state entrepreneurialism and austerity localism. Theoretically, this paper contributes to scholarship which focuses on the contingency and complexity inherent in urban transformation. State and society actors are seen as potential collaborators working pragmatically to solve systemic problems without necessarily targeting wholesale systemic change. Methodologically, it contributes to ongoing attempts to demonstrate the positive relationship between experimental comparisons and conceptual innovation through staging a 'comparative conversation'.

Recent policy initiatives for urban development have changed the relationships among stakeholders in China's urban consolidation processes. Building upon Giddens' (Giddens A (1984) The Constitution of Society: Outline of the Theory of Structuration. Berkeley, CA: University of California Press.) structuration theory and Ostrom's (Ostrom E (2005) Understanding Institutional Diversity. Princeton, NJ: Princeton University Press) institutional analysis and development thesis, this paper develops a power arena analytic framework, and uses it to examine the new power relations among the stakeholders in a dilapidated residential redevelopment project in Shenzhen. Our findings reveal that Shenzhen's new approach incentivised the developer to frame a local decision-making structure which aligned the property owners into two broad groups: those who supported the developer, or cooperative, and those who disputed with the developer, or un-cooperative. Shenzhen's new attempt was unable to balance power distribution between the main stakeholders and caused intense conflicts and poor project outcomes. A range of factors, including passive participation of residents in project preparation, weak mechanisms to curb speculation, and policy inconsistency associated with tiers of governments, were responsible for the poor performance. These findings contribute to the understanding of the complexity in power relations underlying urban development influenced by planning policy. [ABSTRACT FROM AUTHOR]

How has social work, which has emerged as a distinct profession in the PRC with the full support of the party-state, come to produce neoliberal outcomes similar to those found in other, capitalist countries? In this article, I draw attention to the government purchase (goumai) of social work services, which is commonly considered as confirmation of state capacity and leadership rather than the passing on of state responsibilities to civil sectors with tight budgets. Ethnographic research on the actual social work practices in Shenzhen's Foxconn town reveals how neoliberal-style outsourcing has converged with diverse historical legacies, thus creating precarious labour conditions for frontline social workers. Neoliberal dynamics end up filling most of these social work positions with migrant youth from the countryside, reproducing and perpetuating China's rural–urban divide. Institutional efforts at social care may not only reduce the existing inequalities but may also rely upon and even reinforce them. [ABSTRACT FROM PUBLISHER]

Three plant communities of Xiaonanshan Mountain area that are situated close to hillsides and two communities of Yingrenshi Mountain area, one community being scraped fruit-bearing forest and of half natural recovery status, another is located in a place with several fruit-bearing forests around it, which is partially developed. The study com-pared plant composition and diversity in the two regions. The results showed that in aspect of family, genus and species composition of communities, there was no obvious difference between the two regionss, however, family and species number was more in Xiaonanshan than in Yingrenshi area. In composition of every layer species, Xiaonanshan tree layer species were obviously more than that of Yingrenshi, shrub and herb layers in the former also developed well, species number were more;although in Yingrenshi, there were more species in shrub and herb layers, and herb number were al-so less than Xiaonanshan. With respect to Simpson and Shannon-Wiener diversity indices, except for tree layer index of one community in Xiaonanshan was slightly lower than Yingrenshi, all other layer indices and all integral indices in the three communities were higher than Yingrenshi. It is evident that in long-term protected status, in Xiaonanshan, vegeta-tion structure was better and the species number of every layer were more than that of Yingrenshi which was artificially disturbed. Therefore, even if in Yingrenshi two communities have semi-natural development status, and the effect of man-made disturbance was removed, they were still at the recovery preliminary stage. It was also clear that the biodiver-sity of Xiaonanshan communities under long-term protected vegetation gained comprehensive enhancing. In respect of similarity coefficient of communities, all layer coefficient values were lower. The species compositions in different spots of the same region and in the designated different regions were insignificantly different. [ABSTRACT FROM AUTHOR]
