The digital divide has loomed as a sustainable development issue for over two decades and there has been much research in terms of efforts to measure the digital divide from different dimensions and scales. Drawing on spatial agglomeration analysis and multiple linear regression, this paper aims to reveal the spatiotemporal pattern of the prefectural digital divide in China and its determinants. The results show that there is a significant prefectural digital divide in China that is characterized by a decline of ICT development index (IDI) values from the east to the west as well as from core cities to more peripheral ones. Cities with high IDI values are mainly concentrated in large metropolitan areas in eastern China, whereas cities with low values tend to concentrate in poverty stricken regions in central and western China. However, the digital divide has been characterized by a reduction from 2001 to 2015. The results also show that both economic and educational factors have significant influences on the prefectural digital divide in China. During the early stages, the percentage of university students, urban residential income, and the urbanization rate were key factors. However, after 2010, the adult literacy rate and rural residential income determined the digital divide.

Continuous Increase

Chemical fertilizers are important inputs in agricultural production. They not only increase crop yield but also bring many negative effects, such as agricultural non-point source pollution. Therefore, a scientific understanding of the regional differences in chemical fertilizer application and its environmental risks is of significance to promote China’s agricultural development. In this study, we analyzed the spatiotemporal pattern of chemical fertilizer application intensity (CFAI) in China since 2000, evaluated the environmental risks of provincial CFAI, and investigated the internal mechanism behind them. The results showed that the total amount and intensity of chemical fertilizer application in China from 2000 to 2019 presented a trend of increasing first and then decreasing. In 2000 and 2019, provincial CFAI in eastern China was generally higher than that in central and western China, and the environmental risks of provincial CFAI were spatially characterized by “high in the north and low in the south”. Factors such as poor soil conditions, unreasonable farming structure and backward fertilization methods are the main reasons for the continuous increase in the total amount and intensity of chemical fertilizer application, while the construction of ecological civilization and the transformation of society and economy are the main reasons for their decline. Finally, measures such as targeted fertilization, adjusting the use structure of chemical fertilizers, improving fertilization methods and replacing chemical fertilizers with organic fertilizers are proposed to promote the quantity reduction and efficiency increase of chemical fertilizer application in China.

The Impact

Attracted by the urban–rural income gap (URIG), a massive agricultural transfer population has flooded into cities and became a peri-urbanized population due to the restrictions of the household registration system. This trend eventually leads to the rising population peri-urbanization rate (PPUR), which is equal to the proportion of urban resident population with rural household registration in the total residents, and seriously affects the development of new-type people-oriented urbanization. The purpose of this study is to investigate the impact of URIG on PPUR at the national and regional levels using the spatial exploration analysis and spatial Durbin model from the perspective of comparative economic interests. Empirical results revealed that PPUR had high spatial agglomeration, as indicated by high values in Eastern China and low values in Central and Western China. Moreover, the PPUR of most provinces in China was rising, dominated by intermediate values. At the national level, URIG promoted the increase of PPUR in the province, but inhibited the increase of PPUR in nearby provinces. Except for household registration, other control variables, such as industrial structure, fixed asset formation rate, infrastructure, medical resources and land-centered urbanization, also contributed to the PPUR in the province. At the regional level, the URIG of Central and Western China contributed to the increase of PPUR, whereas in Eastern China it inhibited the increase of PPUR. The strong correlation of URIG and PPUR calls for relevant policies for narrowing URIG and reducing PPUR.

The Impact

Marital happiness is an important symbol of social harmony and can help promote sustainable economic and social development. In recent years, the rapid rise of the divorce rate in China, a country where the divorce rate had previously been low, has attracted wide attention. However, few articles have focused on the popularization of information and communication technology's impact on China’s rising divorce rate in recent years. As a first attempt, the provincial panel data during the period 2001–2016 is applied to study quantitatively the relationship between mobile phone penetration and the divorce rate. In order to get more reliable estimation results, this paper uses two indicators to measure the divorce rate, and quantile regression is applied for further analysis. Additionally, one-year to five-year lag times of the mobile phone penetration are used as the core explanatory variables in order to analyse the lagging effect of mobile phone penetration on divorce rate. The result shows that the correlation between the mobile phone penetration and the divorce rate was statistically positive significant in China during the period 2001–2016. Furthermore, the paper also finds that mobile phone penetration had the greatest impact on divorce rate in central China, followed by eastern China, but it was not obvious in western China during this period. From a technological perspective, this paper provides some possible explanations for the rising divorce rate in China in recent years, and further enriches the relevant research on the impact of the development of information and communication technology on societal changes.

Green Development

Regional green development can commendably abide by the theory of dissipative structure. The relative dissipative characteristics taken on by regional development are analyzed, in which the energy factors and resources factors are incorporated into the green economic development and green environment support subsystems (2GE system) in line with the definite input characteristics. A more representative indicator system is established, with positive and negative entropy indexes involved. As Brusselator model and information entropy method are employed to calculate the data of 30 China’s provinces from 2008 to 2015, the findings bespeak that green development in China lays particular stress on green economic development assuming higher environment pressure and cost. The development among various regions is getting progressively and evidently different, which is manifested as potent economic base and abundant natural resources in the Eastern China; the backward green economic development and the progress of green environment in Central China; the pursuit of green economic development at the expense of the green environment in Western China and Northeastern China.

Telemedicine has been around for decades but it has taken foreground in health services recently. When COVID-19 cases started to be reported in the country it brought with itself panic and chaos. At all India level, the adult literacy rate is 77.7%, this could also be linked to unawareness related to the disease in rural areas. The sudden countrywide lockdown imposed was of no help and further worsened the situation for economically weaker section of the society. During the struggle of our nation to overcome the COVID-19 Telemedicine has indeed played a vital role. People in fear of contacting the disease and due to nationwide lockdown were unable to reach their health care provider. People with pre-existing conditions that needs regular monitoring, pregnancy related queries, queries on new symptoms, psychological counselling and many more could not wait for the COVID-19 to be over before they get any help on the issues.­­ Telemedicine shall continue developing and be used in a multitude of settings by more health-care doctors and patients, and these standards of practice will be a crucial driver within this evolution.

Abstract. We simulate elemental carbon (EC) and organic carbon (OC) aerosols in China and compare model results to surface measurements at Chinese rural and background sites, with the goal of deriving "top-down" emission estimates of EC and OC, as well as better quantifying the secondary sources of OC. We include in the model state-of-the-science Chinese "bottom-up" emission inventories for EC (1.92 Tg C yr−1) and OC (3.95 Tg C yr−1), as well as updated secondary OC formation pathways. The average simulated annual mean EC concentration at rural and background site is 1.1 μg C m−3, 56% lower than the observed 2.5 μg C m−3. The average simulated annual mean OC concentration at rural and background sites is 3.4 μg C m−3, 76% lower than the observed 14 μg C m−3. Multiple regression to fit surface monthly mean EC observations at rural and background sites yields best estimate of Chinese EC source of 3.05 ± 0.78 Tg C yr−1. Based on the top-down EC emission estimate and observed seasonal primary OC/EC ratios, we estimate Chinese OC total emissions to be 6.67 ± 1.30 Tg C yr−1. Using these top-down estimates, the simulated average annual mean EC concentration at rural and background sites significantly improved to 1.9 μg C m−3. However, the model still significantly underestimates observed OC in all seasons (simulated average annual mean OC at rural and background sites is 5.4 μg C m−3), with little skill in capturing the spatiotemporal variability. Secondary formation accounts for 21% of Chinese annual mean surface OC in the model, with isoprene being the most important precursor. In summer, as high as 62% of the observed surface OC may be due to secondary formation in eastern China. Our analysis points to three shortcomings in the current bottom-up inventories of Chinese carbonaceous aerosols: (1) the anthropogenic source is severely underestimated, particularly for OC; (2) there is a missing source in western China, likely associated with the use of biofuels or other low-quality fuels for heating; and (3) sources in fall are not well represented, either because the seasonal shifting of emissions and/or secondary formation are poorly captured or because specific fall emission events are missing. More regional measurements with better spatiotemporal coverage are needed to resolve these shortcomings.

It is widely acknowledged that the label “digital divide” can be partially misleading, because it emphasizes a binary dichotomy (“haves vs. have nots”) and a mere technological dimension (in terms of physical availability of devices or conduits). Behind the dichotomous model, however, lie different use and adoption strategies. People cannot be described as being either in or out. Evaluating the complex relationships between technological, social, and human factors raises a number of questions, mainly related to the role of technology in social development. Moreover, we should also reconsider what is commonly meant by information and communication technology. In this chapter, I will try to introduce a multilevel model for analyzing the digital divide, focusing on effective access and new media literacy. The focus will be shifted from technology to humans. In every ICT for development project, local context and local needs should be regarded as the key factors.

The incubator of scientific and technological innovation plays an important role in leading scientific and technological innovation, accelerating the transformation of scientific and technological achievements, and promoting industrial upgrading and transformation. The Chinese economy is in the transition stage, so the research on the operating efficiency of the incubator of scientific and technological innovation based on the Chinese context has its unique value. In this study, combined with Chinese context, the business incubator is divided into two main modes: government and private. By using DEA research method, this chapter analyzes a series of problems, such as the overall difference and difference grade of the operating efficiency of incubators among the four major economic zones of China, the comparison of the operating efficiency of different modes between Northeast and Western regions, and the gap between private-led incubators in eastern China and private-led incubators in Northeast and Western China.

As China is undergoing economic transformation and facing increasing energy and environmental problems, it is essential to pay special attention to sustainable innovation governance. This research took industrial waste and total energy consumption into consideration and uses a super efficiency slack-based measure (SBM) model to empirically evaluate the regional innovation efficiency of Chinese provinces. The results showed that the efficiency of China’s regional sustainable innovation has not changed significantly over recent years. In addition, the results also showed large and varying degrees of innovation efficiency across different provinces. Eastern China, in comparison to central and western China, showed higher innovation efficiency. In addition, we found a slightly increasing trend in terms of innovation efficiency disparities between the three areas. On the basis of these findings, the reasons for the innovation efficiency gap between different regions were analyzed. The impacts of influential factors on sustainable innovation efficiency were further explored. We found that technology market maturity affected sustainable innovation efficiency positively, while government funding had a negative impact on sustainable innovation efficiency. Industrial structure and environmental regulations had no significant effect on sustainable innovation efficiency. Finally, some implications for improving governance performance in terms of sustainable innovation were provided.
