The Evolution, Current Status, and Research on Issues of Smart City Construction in Macau

Since the Macau Special Administrative Region government proposed the construction of a smart city in the first five-year plan in 2015, the smart city construction in Macau has gone through three stages: initiation, construction, and improvement, and has achieved certain results in four areas: government, transportation, tourism, and healthcare. However, due to the limited local market in Macau, a lack of technical talent and investment from technology companies, and insufficient government promotion, the construction of Macau's smart city still lags behind that of developed cities in China's mainland.

Examining the Effectiveness of Housing and House Registration Policies for Raising Inflow of Talents A Case Study in Zhangjiang Science City, Shanghai

With the national economic transformation, the advance of the intelligent manufacturing industry is gradually approaching, which has a direct positive correlation with innovations and the development of high-tech industries. Sufficient technical and entrepreneurial talent supply is the key to maintaining a high level of technological progress and sustaining economic development. Therefore, as one of the most developed cities in China, Shanghai adopts several house-related policies to attract the inflow of advanced talent. This paper examines the effectiveness and feasibility of the housing and household registration policies implemented in Zhangjiang Science City, including shortening the time of transferring temporary residence permit into the registered permanent residence (TR-to-PR) and offering talents apartments to reduce rental pressure of young talents. Four simple quantitative indicators used to analyze the effectuality are the number of talents introduced annually and its growth rate; the number of TR-to-PR groups annually and its growth, respectively. As a result, this paper supports that the policies are effective in promoting talent inflow. However, the future talent retention issue is still alarming and it deserves the attention of policymakers. More policies concerning solving house price bubbles and improving the living environment should be adopted to keep talents stay and contribute to economic development in the long run.

Study on Urban Expansion and Population Density Changes Based on the Inverse S-Shaped Function

For decades, the continuous advance of urbanization has led to the continuous expansion of urban land and rapid increase in the total area of cities. The phenomenon of urban land expansion faster than population growth has become widespread. High population density can lead to problems such as traffic congestion and exacerbated air pollution and can hinder sustainable development, affecting the quality of life of urban residents. China is currently in a phase of rapid urbanization, with high urban population density and rapid decline in urban population density. The decrease in urban population density is conducive to promoting sustainable urban development. This study selected 34 cities in China as sample cities and analyzed the spatial expansion and population density changes using land use and population density data from 2000, 2005, 2010, 2015, and 2020 in order to provide reference for controlling population density and promoting sustainable urban development. The conclusions of the study are as follows: In the 34 sample cities, the average urban radius was only 11.61 km in 2000, but reached 17.98 km in 2020, with an annual growth rate of 2.5%. There were significant spatial differences in urban expansion. Beijing and Shanghai, as the most developed cities in China, had urban radii exceeding 40 km, while the less developed cities of Liaoyang and Suzhou had urban radii of only 9 km. Although the population density decreased in most cities, the population density values in first-tier cities in China, such as Tianjin, Beijing, and Shanghai, continued to rise. Cities with loose spatial expansion patterns had faster decreases in population density than compact-type cities. The rate of urban spatial expansion was negatively correlated with changes in population density, with cities that had faster urban spatial expansion also having faster declines in artificial ground density.

Impacts of anthropogenic discharge on distribution, mass budget, and long-term risk of total mercury in coastal region: A case study of the Jiaozhou Bay, China

Mercury (Hg) as a toxic pollutant in marine systems have been paid more attention. The Jiaozhou Bay (JZB) is located at the western coast of the Yellow Sea surrounded by Qingdao city, a developed city in China. >10 rivers and several sewage treatment plants carry lots of Hg input it, increasing the environmental risks JZB facing. However, there is still a lack of knowledge on its cycling in the JZB, limiting sound understanding of Hg fate in coastal regions. To address these needs, four cruises were conducted in different seasons, to investigate distribution, influencing factors, and mass budget of total Hg (THg) in the JZB. Higher THg concentrations were determined in seawater (22.8±13.9ngL-1) and sediment (148±107ngg-1), indicating serious Hg pollution in the JZB. Temperature, salinity in water and enrich factor (EF) in sediment were identified to be possible environmental factors influencing THg distribution in the JZB. Mass budget of THg showed that anthropogenic discharge (river, wastewater input, and atmospheric deposition) was dominant source of THg in the JZB. The results of statistical analyses and mass budget of THg also indicated that anthropogenic discharge plays important roles in long-term risk of THg in the JZB. These results suggested that anthropogenic discharge comprehensively affects distribution, mass budget, and long-term risk of THg in coastal systems. The outcomes highlighted that regular investigations of Hg cycling should be conducted to assess Hg pollution in coastal ecosystems. Our study also shed new light on control of long-term risk posed by Hg in marine systems according to investigations of Hg cycling and link between Hg contamination and other pollutant (e.g., nutrient).

RESIDENTIAL SPATIAL DIFFERENTIATION AT THE COMMUNITY LEVEL IN HANGZHOU, CHINA

Residential spatial differentiation is an important social issue for every large city to explore. The “subcultural” clusters formed by the subjective choices of a city’s residents divide the living spaces of the city and create residential differentiation. A study of this phenomenon would help to facilitate the allocation of urban resources and the formulation of relevant development strategies. In recent years, Hangzhou, one of the major developed cities in China, has seen a gradual increase in the proportion of its non-local population. Employing principal component analysis and K-means clustering, this study investigated the city’s spatial differentiation of living spaces at the community level and identified the social clustering areas. The Shannon-Wiener index and the index of dissimilarity were used to examine the degree of residential segregation in each administrative district. The results showed that the functional distinctions among the districts of Hangzhou were pronounced and had certain degrees of class solidification. A certain spatial coupling was observed between residential differentiation and housing prices. More reasonable allocations of social resources would help to ameliorate the negative effects caused by the spatial differentiation of living spaces.

Effect of built environment on BMI of older adults in regions of different socio-economic statuses.

Numerous studies have ignored the influence of underdeveloped urban surroundings on the physical health of China's ageing population. Lanzhou is a typical representative of a less developed city in China. This study investigated the relationship between body mass index (BMI) and built environment amongst older adults in regions of different socio-economic statuses (SES) using data from medical examinations of older adults in Lanzhou, as well as calculating community built environment indicators for regions of different SES based on multiple linear regression models. Results showed that age and underlying disease were negatively associated with overall older adult BMI in the study buffer zone. Land use mix, number of parks and streetscape greenery were positively associated with older adult BMI. Street design and distance to bus stops were negatively connected in low SES regions, but population density and street design were negatively correlated in high SES areas. These findings indicate that the built environment of SES regions has varying impacts on the BMI of older persons and that planners may establish strategies to lower the incidence of obesity amongst older adults in different SES locations.

Assessing the Potential of Vegetation Carbon Uptake from Optimal Land Management in the Greater Guangzhou Area

Rapid urbanization has threatened sustainable urban development in many cities across the globe, causing green space loss and vegetation cover degradation which reduce carbon sequestration. Optimal land management practices (LMPs) in an urban context are known as ways capable of promoting urban vegetation growth and contributing to carbon sequestration. Due to variations of physical, biological, and social structures in urban areas, policymakers often lack relevant information to decide and implement site-specific LMPs. Here we try to extract the areas in need of the optimal LMPs, identify location-dependent optimal LMPs, and assess how much more carbon can be captured by applying a combination of segmenting homogeneous urban environments and neighborhood-based analysis. As one of the most developed cities in China, the greater Guangzhou area (GGA) was selected as a case study. We found that the carbon uptake from the urban vegetation in GGA could be improved on average by 185 gC m−2 yr−1 in flux (or 1.3 TgC yr−1 in total) with optimal LMPs, equivalent to a ~30% increase considering the current level of 662 gC m−2 yr−1 in flux (4.4 TgC yr−1 in total). The carbon uptake potential was found to differ considerably across locations and among different ecosystem types, highlighting spatially varied priorities for implementing optimal LMPs over the space. This study reveals the usefulness of the model in assessing carbon uptake potential from optimal LMPs and emphasizes that future urban planning may consider the importance of optimal LMPs in enhancing vegetation carbon uptake in urban planning.

Knowledge, attitudes, and practices toward cancer pain management amongst healthcare workers (physicians, pharmacists, and nurses): a cross-sectional study from first-tier cities in China.

China is currently one of the countries with the largest increased number of new cancer cases in the world, but cancer pain management (CPM) is still inadequate. This study uses a questionnaire to demonstrate the status and differences in knowledge, attitude and practice (KAP) of CPM among healthcare workers (HCWs) in developed regions of China, to find deficiencies and priorities for improvement, from which areas and advantages of the role of pharmacists and mobile devices can be explored. This study used data from a questionnaire on CPM from March to June 2019. The study population consisted of a total of 515 HCWs in four first-tier developed cities in China. The questionnaire has four major components, analysis of differences in KAP of different occupations through one-way analysis of variance (ANOVA). Among the respondents, the physicians had the highest knowledge scores toward CPM, pharmacists had the lowest practice scores. Around half of the respondents indicated that their hospital or department have a pharmacist participating in CPM. Physicians and nurses were more likely to expect pharmacists to provide drug counseling. The HCWs interviewed most expect that the mobile-based pain management system can automatically screen and mark patients with pain. From this study, it can be suggested that pharmacists and nurses in the CPM team should actively promote relevant knowledge. Besides, pharmacists should focus on improving practical ability such as increasing the frequency of pain assessment. Multidisciplinary collaboration and the introduction of mobile devices can improve and refine the CPM.

Consumption and cost trends of EGFR TKIs: influences of reimbursement and national price negotiation

BackgroundEpidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have been widely used in the treatment of EGFR mutation non-small-cell lung cancer. The Chinese government has made great efforts to improve the availability and affordability of these drugs. The aim of this study was to investigate the trends in the consumption and cost of EGFR TKIs in Nanjing, a developed city in China, and evaluate the influence of health insurance coverage and national price negotiation on drug consumption.MethodsData about EGFR TKIs applications in 2010–2019 were extracted from Jiangsu Medicine Information Institute. Five types of EGFR TKIs were included. Consumption was expressed in defined daily doses (DDDs) and expenditure. The correlation between defined daily cost (DDC) and DDDs was analyzed by Pearson's correlation test.ResultsThe DDC, number of DDDs and expenditure of EGFR TKIs changed little from 2010 to 2015. National price negotiation was initiated as a policy and low-price generic gefitinib came into the market in 2016. Three types of EGFR TKIs moved into the coverage of the national health insurance since 2017. Hence, the DDC decreased, and the number of DDDs increased significantly year by year since 2016. The first generation TKIs always made up of comprised the majority of the total consumption. The predominantly prescribed TKIs were gefitinib and icotinib. DDC was negatively correlated with the number of DDDs. The number of DDDs increased significantly after health insurance enrollment, price negotiation and generic drug replacement.ConclusionThe consumption of EGFT TKIs has increased and the DDC of EGFR TKIs has decreased since 2016. These trends may be attributed to drug reimbursement, price negotiation and generic drug replacement. Further efforts are needed to translate the high consumption of EGFR TKIs into clinical benefits.

Policy‐driven education‐led gentrification and its spatiotemporal dynamics: Evidence from Shanghai, China

AbstractAs a highly sought‐after resource by parents, quality schools exert a strong influence on the housing market and other aspects of social life worldwide. Given the long‐lasting prominence of education in urban society, scholars extensively explored the interplay between education and housing dynamics and their sociospatial implications, among which the scholarship on education‐led gentrification offers a prominent and productive conceptual lens. While the literature on education‐led gentrification in developed economies is proliferating, little is known about the dynamic linkages between school choice and residential segregation in developing contexts, including China. Drawing on a longitudinal housing transaction (2011–2020) dataset covering 762 residential neighbourhoods in Shanghai, the largest and most developed city in China, this research quantitatively examines the process of gentrification driven by the accessibility to educational resources and its spatiotemporal dynamics. Based on analyses employing hedonic price models and a geographically and temporally weighted regression model, this study reveals the uneven evolution of education‐led gentrification across space and time. Specifically, this study argues that the spatial variations in education‐led gentrification in Shanghai and its temporal changes are largely policy driven. This finding foregrounds schools as an important driver of gentrification rather than merely a “downstream effect” of the existing gentrification process, especially in recently gentrifying suburbs. Therefore, this study adds novel conceptual and empirical insights to the scholarship of education‐led gentrification in non‐Western contexts in particular and the literature on the geographies of education in general.

The risk characteristics of heavy metals in urban soil of typical developed cities in China

With the rapid development of China's industrial economy, heavy metals continue to accumulate in the environment, which has created serious threats for the ecological environment and human health. This study collected 50 surface soil samples in Nanjing, a typical developed city in China, and the contents of Al, Ca, Fe, Mg, Mn, Ni, Ti, Cd, Cr, Cu, Pb, and Zn in the samples were determined. Combined with the ecological risk index and the health risk assessment model, the risk of soil heavy metals in Nanjing was comprehensively evaluated. The results show that the variation coefficients of Pb and Cu are distinctly large, and these elements are all slightly polluting. Children are at a high risk of exposure in various ways, among which Pb and Cu elements have a high risk of causing non-carcinogenic issues. The results of the correlation analysis showed that the content changes of Pb, Zn, and Cu had extremely significant correlations, indicating that they may have the same source. The results of the principal component analysis showed that industrial sources in Nanjing contributed the most heavy metals, reaching 34.4%. The second largest source was from parent material and fertilizer, which contributed 32.3% and 19.6%, respectively. The sources with the lowest contributions were from weathering and deposition, which reached 13.7%. The results of this study will provide guidance and reference for risk-source analysis, early warning, and management of soil heavy metals in developed cities.

Investigation of the Factors Influencing the Purchase of Personal Accident Insurance in Tier One Cities in China

Personal Accident Insurance (PAI) has played an important role in the livelihood security of the residents in China, which is unlike the situation in most developed countries. But in recent years, it has been showing a significant reduction in the growth rate of the annual premium, and it is even -0.16% in 2020 compared to 2019. To study the decisive factors affecting the purchase of PAI, the willingness to purchase PAI and its influencing factors have been investigated based on the data collected from the residents of Shanghai, one of the most developed cities in China. A questionnaire was conducted to collect the data and the chi-square test of independence and histograms have been used to perform analysis. Our results indicate that PAI coverage in Shanghai is about 33%. The unwillingness to purchase PAI has been mainly ascribed to the residents’ weak awareness of the PAI, due to either subjective reasons or objective reasons. Measures have been suggested to change the declining situation.

Spatial separation of microbial communities reflects gradients of salinity and temperature in offshore sediments from Shenzhen, south China

The rapid industrialization and urbanization around the coastal region have resulted in a pollution pressure in Shenzhen, one of the most developed cities in China. However, microbial communities of coastal sediment and their environment quality are far from understood. Here, 16S rRNA gene sequencing was conducted to investigate the microbial community of offshore sediments from 20 coastal areas in Shenzhen and the factors affecting that variability. Results showed there was a significant difference on the diversity among the 20 sites, and notable difference between the western and eastern offshore sediments were observed. The microbial community was dominated by Nitrosopumilaceae, Flavobacteriaceae, Pirellulaceae, Woeseiaceae, Anaerolineaceae and Saprospiraceae at the family level. The abundance of Woeseia, Candidatus Nitrosopumilus, Muriicola, and Rhodopirellula were higher in samples from eastern sites, while Cyanobium PCC-6307, Acinetobacter, Sulfurovum, Robiginitalea, and Nitrospira were enriched in western sediment samples. PICRUSt-based prediction of metagenomes indicated the KEGG pathways about amino acid metabolism, carbohydrate metabolism, and energy metabolism were significantly more abundant in eastern sediments. Moreover, salinity, pH and temperature were the important environmental factors shaping the structure of microbial communities. These findings are important for understanding the relationships between bacterial communities and environmental conditions in coastal ecosystems, and provide a scientific basis for offshore ecosystem conservation.

Utilization of community health care centers and family doctor contracts services among community residents: a community\u2010based analysis in Shenzhen, China

BackgroundFamily doctor contract services (FDCS) began in China in 2016. Shenzhen, one of the most developed cities in China, also implemented a family doctor (FD) policy in 2017. The objectives of this study were to identify the impact of awareness of FDCS and signing service contracts with FDs on utilization of community health care centers (CHCs).MethodsCross-sectional secondary data based on residents living in Luohu district was used for analysis. Descriptive analysis was conducted to identify utilization of CHCs by awareness of FDCS and signing service contracts with FDs, respectively. Linear probability models (LPM) were used to determine the association of utilization of CHCs with awareness of FDCS and signing service contracts with FDs, respectively.ResultsAmong 1205 adults included in the analysis, 27 % of the participants knew about the FDCS, 5 % signed with FD, and 20 % had chronic disease. Both awareness of the FDCS and signing service contracts with FDs significantly increased the probability of using CHCs as a first choice.ConclusionsThis study provided evidence that both awareness of FDCS and signing service contracts with FDs had a positive impact on utilization of primary health care services at the community level. More interventions to improve awareness of FDCS are needed to increase the utilization of primary health care services.

The Influence of E-Commerce on the Foreign Trade of Shanghai Free Trade Zone

Purpose: As one of the most developed cities in China, the application of e-commerce is more mature, especially the promotion of ecommerce to foreign trade. After the establishment of Shanghai Free Trade Zone (FTZ) in 2013, the government issued a series of policies to promote the application of e-commerce in Shanghai's foreign trade. This paper takes Shanghai FTZ as an example to study how to develop the application of e-commerce in other free trade zones and how to innovate the international trade mode. Research design, data and methodology: This paper selects the latest data from 2010 to 2019, uses econometric correlation analysis and regression analysis to study the impact of e-commerce on the foreign trade of Shanghai FTZ. Results: At last, the conclusion is drawn that the establishment of free trade zone provides many advantages for the development of e-commerce in Shanghai, and the growth of e-commerce in Shanghai FTZ promotes the development of foreign trade of Shanghai FTZ. Conclusions: So as to promote the development of e-commerce in Shanghai Free Trade Zone, some suggestions are put forward, such as increasing network supervision, establishing e-commerce talent training system, logistics management and information management systematization.

Exploring the Relationship between Urbanization and the Eco-Environment: A Case Study of Beijing

Beijing is one of the most developed cities in China and has experienced a series of environmental problems. In accordance with the Major Function Zone planning, Beijing is divided into four zones in an attempt to coordinate development between urban areas and the eco-environment. Classic coupling model uses statistical data to evaluate the interactions of these two subsystems; however, it lacks the capability to express dynamic changes to land cover. Thus, we extracted land cover data from Landsat images and examined the urbanization and eco-environment level as well as the coupling coordination in Beijing and its functional zones. The main conclusions are as follows. (1) Between 2001 and 2011, both urbanization and the eco-environment level in Beijing and its functional zones grew steadily. Different zones coordinated together according to their own characteristics, and the overall coupling coordination of the city transformed from the “basically balanced” to the “superiorly balanced” stage of development. (2) After 2011, the condition of the eco-environment worsened in Beijing and in most of the function zones, while the coordination between increased urbanization and the worsened eco-environment may be a result of environmental lag. This study integrated land cover data into the coupling mode and fully utilized the advantages of spatiotemporal analysis and the coupling model. In other words, the spatiotemporal analysis explains the land cover changes visually over the research period, while the coupling model explores the interaction mechanisms between urbanization and the eco-environment. The land cover data enriches the coupling theory and provides a reference for evaluating the effectiveness of local development policy.

Early technology education in China: A case study of Shanghai

ABSTRACT While Science, Technology, Engineering and Mathematics (STEM) education is increasingly valued in China, there is little research to understand how science, technology, engineering, and math are best integrated into early childhood education. This study aims to examine Chinese educators’ views and perspectives on early technology education – ‘the missing T & E in early childhood’ – in Shanghai, the largest and the most developed city in China. Altogether, 120 educators were surveyed, including kindergarten principals (N1 = 12), administrators (N2 = 11), and teachers (N3 = 97), and three were also interviewed individually. The results indicated that: (1) most of the Shanghai kindergarten teachers were not literate in information technology; (2) children’s development levels, teachers’ technological literacy, and limited resources were widely regarded as obstacles to early technology education; and (3) the technology curriculum and digital technology should be carefully designed to cater to young children’s needs.

Are people willing to pay more for new energy bus fares?

Abstract This paper adopts the contingent valuation method to study people's willingness to pay for the adoption of new energy buses in the four most developed cities of China: Beijing, Shanghai, Guangzhou and Shenzhen. An interval regression model is employed to analyze the influencing factors of people's willingness to pay and estimate the exact amount of extra money people would pay per fare. The results show that approximately eighty percent of the respondents in the four cities would like to pay extra fare to support the adoption of new energy buses and the specific amount is 0.653 RMB/fare among all the respondents. Those with higher household income, who are younger, who think the adoption can significantly improve air quality and who deem that they live in a place with good air quality are willing to pay higher. But public concern about energy security issue in China does not have significant impact on the willingness to pay. It is therefore recommended that setting a higher price for new energy bus fare is reasonable and more knowledge of new energy buses should be conveyed to the public, especially its purpose of improving air quality and alleviating the high pressure of energy security.
