AbstractOver the last two decades, scholars have pointed to the significance of the impact of extreme events on consumption, a prominent part of national economies. How does the COVID‐19 epidemic influence consumption? Using high‐frequency payment system panel data, we explicitly consider the individual consumption changes and the substitution effect between online and offline markets of multiple categories by constructing autoregressive integrated moving average (ARIMA) models and conducting regression analyses. The p value and regression coefficients of the substitution elasticity are used to estimate the changes and the substitution effects from the offline to the online channels. The results show that consumption saw a remarkable decline after the surge of COVID‐19 in 2020 compared to 2019. Overall, online markets were more resilient than the offline markets and the substitution effects after the epidemic's outbreak between the online and offline markets were significant for one‐third of the consumption categories. However, the online market could not replace the offline market for some categories due to the product characteristics. The vulnerable industries in the face of the epidemic's intervention are determined as being traditional catering, transportation, tourism, and education, and the shortage of healthcare services in extreme events is also pointed out. The results provide suggestions for policies on targeted enterprises and public service.

Urban green spaces facilitate children's physical activities by providing opportunities for engagement with natural settings. However, there is a lack of empirical research examining the nexus between the greenery features and spatial quality in urban parks and park-based physical activities among children. Moreover, the influence of children's perceptions of their environment has been overlooked. Through the application of remote sensing and field surveys, we evaluated the greening and quality of 34 play spaces within 20 urban parks, employing on-site measurements and unmanned aerial vehicle observations to identify and quantify the intensity and density of children's physical activities. Utilizing Hierarchical Linear Modeling and Simple Mediating Modeling, we investigated the mediating effects of green spaces on physical activity and perceived environmental qualities. Our findings indicate a curvilinear (inverted U-shaped) relationship between urban park greening metrics, such as vegetation diversity and green view index, and the dosage of children's physical activity. The interplay between the quality of space and greening level in shaping physical activity demonstrates complex dynamics of synergy and competition. The greening level of play spaces positively impacts the intensity and density of children's physical activities and is partly moderated by perceived environmental factors, notably safety and attractiveness. These insights contribute empirical evidence and decision-making guidance for urban greening and the development of child-friendly urban spaces.

AbstractMember commitment has an impact on the viability and success of cooperatives. While there are studies on member engagement in European and American cooperatives, empirical research on member commitment in Chinese agricultural cooperatives is rare. Using a sample of 391 farmer cooperative members in China, this study investigates the factors associated with member commitment, particularly whether trust in the cooperative leadership and social pressure at village level affect member commitment. In addition, the study explores the pathway how trust and social pressure affect member commitment by employing structural equation modelling. Our results show that both trust and social pressure are positively associated with the three components of member commitment – affective commitment, continuance commitment and normative commitment – in a direct way. Furthermore, trust in the leadership impacts affective commitment indirectly via the mediation of member participation. These findings can be used by cooperative leaders, policy makers and rural administrators to strengthen member commitment and thereby the economic viability of agricultural cooperatives and the communities in which they are embedded.

AbstractThis article examines the long‐term effects of the administrative system using the Great Wall as a geographical discontinuity. Using town‐level nighttime light luminosity per capita as a measure of economic development, we find that today, luminosity per capita is significantly and robustly higher in towns south of the Great Wall than in those north of it. The holding of resource allocation authority by the administrative hierarchy and the uniform enforcement of justice by hierarchy officials were advantageous for city building and judicial cross‐territory enforceability on the south side of the great wall, which had a long‐term impact on the imperial bureaucracy.
