Under the influence of complex urbanization, improving the carbon emission efficiency (CEE) plays an important role in the construction of low-carbon cities in China. Based on the panel data of 283 prefectural-level cities in China from 2005 to 2017, this study evaluated the CEE by the US-SBM model, and explored the spatial agglomeration evolution characteristics of CEE from static and dynamic perspectives by integrating ESDA and Spatial Markov Chains. Then, the spatial heterogeneity of the impacts of multi-dimensional urbanization on CEE were analyzed by using the Geographically and Temporally Weighted Regression (GTWR). The results show that: (1) with the evolution of time, the CEE has a trend of gradual improvement, but the average is 0.4693; (2) from the perspective of spatial static agglomeration, the "hot spots" of CEE mainly concentrated in Shandong Peninsula, Pearl River Delta, and Chengdu-Chongqing urban agglomeration; The dynamic evolution of CEE gradually forms the phenomenon of "club convergence"; (3) urbanization of different dimensions shows spatial heterogeneity to CEE. The impact of economic urbanization in northern cities on CEE shows an inverted "U" shape, and the negative impact of spatial urbanization on CEE appears in the northwest and resource-based cities around Bohai Sea. Population and social urbanization have a positive promoting effect on CEE after 2010. These findings may help China to improve the level of CEE at the city level and provide a reference for low-carbon decision-making.

Background: The health-related quality of life and subjective well-being of young people need to be confirmed at the population level by identifying protective factors such as social support and their current healthy lifestyle. This study aims to examine a healthy lifestyle as a mediator of the associations between perceived social support to subjective well-being and health-related quality of life and also to analyze the associations between all these variables.
Methods And Materials: This study was conducted by cross-sectional survey of university students (N = 348) derived from ten cities/municipalities in East Kalimantan, Indonesia.

Smog pollution is a major global issue affecting Pakistan's major cities, particularly Lahore. The study aims to explore the public perception and willingness to pay (WTP) for smog reduction via the Contingent Valuation Method (CVM). This study uses a structured interview schedule and interval regression model to analyse the public perception and willingness to pay for smog reduction.

Utilizing innovative methods to advance the research and development (R&D) of health products and enhance their accessibility has become crucial to achieving universal health coverage, addressing public health emergencies, and promoting population health and wellbeing. However, structural contradictions do exist in the supply and demand of health products in the Association of Southeast Asian Nations (ASEAN). With the joint support of the Ministry of Science and Technology of China, the Ministry of Education, and the China-ASEAN Center, Peking University established the China-ASEAN Science and Technology Cooperation Center for Public Health in April 2023.

Background: With the implementation of the hierarchical medical system (HMS) in China, Zhejiang Province introduced an innovative payment scheme called "payment method by disease types with point counting". This scheme was initially adopted in Jinhua in July 2017, and was later integrated with the "same disease, same price" policy in Hangzhou in January 2020. This study aimed to investigate the impact of these reforms on the distribution of health service volume.
