Summary: This study explores the impacts and mechanisms of R&D capital market distortions on innovation efficiency (IE) using a dynamic spatial Durbin model. The results suggest that IE in China exhibits temporal inertia and spatial agglomeration. R&D capital market distortions have a weakening effect on IE in both short and long term, but they also have significant spatial interaction and positive spatial spillover effects. R&D capital mismatch and technology lock-in effects are identified as essential mechanisms inhibiting IE.

Summary: This study measures the degree of resource curse in China using an improved resource curse index model and investigates its spatial agglomeration characteristics, influencing factors, and spatial spillover effects based on a spatial statistical model. The research findings indicate that the resource curse in China is deep but showing a downward trend and being alleviated. There are significant regional and provincial differences in the degree of resource curse, with most regions and provinces experiencing a decline. The spatial agglomeration of China's resource curse is evident, forming a resource curse club centered on Shanxi, Shaanxi, Ningxia, Qinghai, and Inner Mongolia. Environmental regulation, technological innovation, industrial agglomeration, human capital, and urbanization level are the main factors alleviating the resource curse, while foreign direct investment and industrial structure exacerbate it. The spatial spillover effect of the resource curse is significant, and the resource curse in local provinces is influenced by the resource curse in neighboring provinces. The spatial spillover effects of industrial structure, human capital, foreign direct investment, and technological innovation are also significant.

Summary: Good access to greenspace and healthy food has been associated with positive health outcomes, but some studies have found no significant relationship. Examining inequalities in accessing greenspace and healthy food in disadvantaged neighborhoods can reveal racial/ethnic disparities in segregated cities. However, existing studies often focus on measuring inequality in accessing either greenspace or healthy food alone, leading to an inaccurate depiction of disadvantaged neighborhoods' healthy living environments. This study aims to improve the assessment of doubly disadvantaged neighborhoods by considering accessibility to both greenspace and healthy food in Chicago. The results show that black-majority neighborhoods are the most doubly disadvantaged in terms of exposure to healthy living environments. This study can inform policymakers to allocate more resources to improve the urban environment in these doubly disadvantaged neighborhoods.

Summary: This study advances the measurement of community social context by introducing a daily dynamic perspective and explores the relationship between community social context and community attachment. It measures the social context averaging or polarization effect of communities using census and cell phone data and investigates residents' community attachment in 71 communities in Guangzhou, China. The study finds that social contexts of many communities vary during the day, with distinct patterns during work hours, evening hours, and night hours. Considering variations in social contexts during evening hours significantly enhances the explanation of heterogeneity in residents' community attachment. The study suggests that context dynamics should be considered as a new dimension of community indicators and highlights the importance of targeting specific space and time periods in community governance practice.

Summary: Annoyance caused by environmental noise is a significant health burden. However, our understanding of noise's health impacts is limited by fixed contextual units and limited sound characteristics used in exposure assessments, as well as assumptions about exposure-response relationships. To address these limitations, this study analyzes the complex relationships between noise annoyance and real-time noise exposure in various activity microenvironments and times of day, considering individual mobility, multiple sound characteristics, and nonstationary relationships. The results show that sound level and sound increment have nonlinear effects on momentary noise annoyance, and different sound characteristics can have a joint effect. Additionally, daily activity microenvironments and individual sociodemographic attributes can also affect noise annoyance and its relationship with sound characteristics. These findings provide scientific evidence for creating acoustically comfortable living environments.
