Scientific study of the temporal and spatial distribution characteristics of haze is important for the governance of haze pollution and the formulation of environmental policies. This study used panel data of the concentrations of particulate matter sized < 2.5 μm (PM_2.5) in 340 major cities from 1999 to 2016 to calculate the spatial distribution correlation by the spatial analysis method and test the temporal convergence of the urban PM_2.5 concentration distribution using an econometric model. It found that the spatial autocorrelation of PM_2.5 seemed positive, and this trend increased over time. The yearly concentrations of PM_2.5 were converged, and the temporal convergence fluctuated under the influence of specific historical events and economic backgrounds. The spatial agglomeration effect of PM_2.5 concentrations in adjacent areas weakened the temporal convergence of PM_2.5 concentrations. This paper introduced policy implications for haze prevention and control.

It is not that the public is unwilling to participate in environmental protection, but rather that they lack the appropriate information. The media offers an alternative explanatory pathway to understanding citizens’ willingness to pay (WTP) for environmental governance, but the existing literature still lacks empirical studies on this topic and the intermediate mechanisms. Adopting an environmental communication perspective, this paper divided the environmental effects of media into two dimensions: knowledge growth and responsibility cultivation, and conducted an empirical analysis on whether, and how, media use affected citizens’ WTP, based on data from the China General Social Survey 2018 (hereafter, CGSS2018). The findings found that the frequency of media use significantly increased citizen’s WTP, in which individual environmental responsibility rather than environmental knowledge played a mediating effect; i.e., media use increased individuals’ WTP by increasing the public’s environmental responsibility. Furthermore, this study discovered that traditional media use had a significant effect on the citizens’ WTP, again verifying the mediating effect of individual environmental responsibility, while new media use did not have such a communication effect. This study extends the theories related to pro-environmental behaviors, and provides practical implications for the government to promote environmental governance and sustainability.

Despite the growing body of evidence addressing the reasons behind vaccine hesitancy, the positive role of media as a key environmental factor influencing vaccination, as well as its function in publicizing and encouraging vaccination, has been less thoroughly explored. This study focuses on the context of the current Monkeypox epidemic, examining the influence of media release channels and message framing on the public’s willingness to receive the Monkeypox vaccine. The findings are empirically validated through a survey experiment conducted in China. The study reveals that both media channels—traditional TV media, official online media, and user-generated media—and media content framings, specifically thematic and episodic, significantly impact the public’s willingness to be vaccinated against Monkeypox. Notably, in the context of this public health event, individuals were more inclined to trust the episodic framing of traditional TV media and the thematic framing of official online media. Compared to thematic framing, episodic framing generally enhances respondents’ willingness to vaccinate. Furthermore, user-generated media exhibited a more negative effect on vaccination intentions during the Monkeypox epidemic, particularly when combined with episodic framing. Heterogeneity analysis indicated a significant difference in the effectiveness of official online media based on audience identity (student vs. non-student), with the student group showing a preference for official online media channels. The findings underscore the importance of public health communication in carefully selecting media release types and message framings. Additionally, it is crucial to consider audience heterogeneity and to employ differentiated communication methods to enhance the effectiveness of vaccine promotion.

Nowadays, with the development of China’s economy and the acceleration of urbanization, the development of urban agglomerations in China has been elevated to an unprecedented strategic height, with people’s needs for a better life becoming increasingly common. Systematic research on the renewal of community public facilities in the third space becomes particularly important. Dialogue-type urban public aim to discusses the design of dialogue-type urban public facilities under the background of urban renewal. With the micro-renewal of urban public landscapes as the research object, the paper aims at preserving peolple’s urban memories and retaining the urban style based on people’s needs. In view of the current problem of lack of dialogue in urban public facilities, this paper carries out research on the construction of public facility system centered on dialogues with people, sceneries and fields, so as to reshape the diversified and complex value of humanization and interpersonalization of public facilities. Through the construction of dialogues with people, sceneries and fields, dialogue-type urban public facilities can achieve the design goals of multiple integration between people and nature, three-dimensional integration of space fields, and an ever-lasting urban style. In this way, under the guidance of micro-renewal of urban public facilities landscapes, construction of public facilities in residential communities can be integrated with the society and environment to form diversified spatial forms and functional facility systems, thereby stimulating the vitality of the city and further exploring and new models of urban renewal.
