Data cleaning and fusion are used to construct a spatial dataset of an eco-environmental problem: PM_2.5 concentrations. The geostatistical analysis tool ArcGIS is used to identify the most suitable interpolation method for reflecting this eco-environmental problem based on multiple parameter adjustments and repeated testing. A hotspot distribution map of PM_2.5 concentrations is generated, and correlation analysis is conducted on the population density and distribution patterns in these hotspot areas. This enables the quantitative analysis and exploration of the spatial characteristics and coupling relationships of PM_2.5 concentrations. The results show a positive correlation between the PM_2.5 concentration distribution and the points of interest, road network density, number of dead-end roads, and average building height in Shenzhen. No correlation is found between population and building densities and the PM_2.5 concentration distribution, possibly due to the city’s effective environmental management and pollution control measures. These findings help advance the development of precise, scientific, legally compliant pollution control strategies and decision-making processes.

In 2017, China implemented the Pilot Policy on Clean Winter Heating in Northern China, aiming to achieve high central heating coverage and cleaner energy consumption. Studying the effects of this policy can help promote its implementation and serve as a reference for effective adjustment of the contents in the future. However, few studies have investigated this policy and its carbon reduction effects, and most focus on the provincial or city levels. Therefore, this paper considers the policy’s influence on air pollution and carbon emissions at the county level to provide a precise and comprehensive assessment of the policy effects. We use panel data from 1 290 counties in 15 provinces in Northern China from 2014 to 2021, applying a multiperiod difference-in-differences model to quantify the impact of the policy on carbon emissions and air quality in the pilot area. We then conduct a series of tests to demonstrate the robustness of the results and analyze the mechanisms of the policy effects from two perspectives, namely, central heating and natural gas use, through a mediating effect model. Finally, we examine the heterogeneity of policy effects between counties based on geographic location and per capita income levels of rural residents through a moderating effect model. The results reveal that the policy significantly reduces air pollution and carbon emissions in the pilot area by increasing the central heating area and natural gas use. Compared with the central and western regions in the north and areas with low-income rural residents, the policy effects in the eastern regions in the north and areas with high-income rural residents are more pronounced.</div></div>","PeriodicalId":45743,"journal":{"name":"Chinese Journal of Population Resources and Environment","volume":"23 1","pages":"Pages 85-95"},"PeriodicalIF":3.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the value realization of ecological products (EP) faces challenges in four major aspects: quantification, trading, transformation, and sustainability. At this stage, seeking breakthroughs to form a stable development path for the realization of the value of EPs is crucial. This paper examines the Guilin Sustainable Development Innovation Demonstration Zone and conducts a case study on oil tea, a characteristic EP. Based on the value realization of EPs, this paper analyzes the oil tea industry in terms of three functions: ecological protection, regional economic development, and traditional cultural support. Drawing on the theory of the gross ecosystem product, this paper examines the role of the value realization of oil tea in improving the quality of the urban living environment and ecosystem functions in Guilin. The results can help promote research on the shaping effects of endemic EPs on sustainable development with respect to the urban economy. Taking a human-centered perspective, the principles of landsenses ecology and traditional ecological knowledge can help analyze the social, historical, and cultural value of oil tea. Combined with on-site research data, a relationship map centered on oil tea culture is created to explore the importance of developing traditional cultural attributes of local EPs in promoting cultural customs, protecting the cultural diversity of ethnic minorities, and driving the development of the cultural tourism industry. By constructing a sustainable urban development model centered on developing local characteristic EPs with the core elements of ecology–economy–traditional culture, this paper aims to strengthen the ecological protection function of cities, promote high-quality economic development, and enhance the soft power of traditional culture.

However, with increasing industrialization and urbanization, there is a growing mismatch between China’s ecological resilience (ER) and economic level (EL) of development, which poses a notable social threat. Currently, the link between ER and EL in China remains unclear, especially in terms of spatial dislocation (SD), referring to the disconnect between the locations where environmental impacts occur and those where economic benefits or activities are concentrated. Therefore, this paper aims to provide theoretical support and an empirical basis for policy-based solutions to address this gap. Based on the SD theory, this study systematically discusses the temporal changes, spatial patterns, and SD characteristics of China’s ER and EL using spatial auto-correlation and barycentric analysis to analyze data from 30 provinces covering the period 2011–2021. The key results are as follows. China’s ER shows a general trend of growth; however, its distribution is uneven. The spatial pattern generally decreases from the southeastern coastal provinces to the northwest. Moreover, a gradually increasing positive correlation is observed between the ER and EL, but this correlation varies by region, with some showing regional linkages and others developing independently. Finally, the dislocation index of ER and EL presents divergent results based on region—the eastern and central regions primarily show a high level of dislocation, whereas the western and northeastern regions show a low level of dislocation. The results provide a comprehensive overview of the spatiotemporal patterns in the association between ER and EL in China. The results emphasize that to balance sustainable regional development and ecological governance, a region-specific approach must be employed, prioritizing innovation-driven strategies for high ER in more developed regions and market-oriented strategies in less developed regions.</div></div>","PeriodicalId":45743,"journal":{"name":"Chinese Journal of Population Resources and Environment","volume":"23 1","pages":"Pages 40-48"},"PeriodicalIF":3.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs panel data from 293 Chinese cities from 2014 to 2022 to systematically analyze the impact of the Zero-Waste City policy on PM_2.5 concentration using a difference-in-differences model. The findings indicate that the policy not only directly reduces PM_2.5 concentration but also indirectly curbs PM_2.5 emissions by enhancing green innovation and green economic efficiency. Moreover, the policy’s effects are found to be positively moderated by urban energy dependence and digital financial inclusion, while they are negatively moderated by the government debt ratio.
