Analyzing their environmental impacts offers a novel perspective for exploring the complex interplay among human production, consumption, and the ecological environment at a micro level. In this study, Shaanxi Province farmers were selected as field survey participants. Based on a quantitative assessment of farmers’ ecological footprints within the study area, how their participation in rural tourism affected ecological footprints was analyzed using the propensity score matching model, and the heterogeneity of the impact and underlying mechanisms were further explored. Results indicate that the ecological footprint of farmers varies significantly across land-use types and consumption categories. Moreover, the spatial distribution of the ecological footprints exhibits a distinct “high at both ends and low in the middle” pattern. Participation in rural tourism significantly reduces the ecological footprint, particularly among farmers with higher levels of social trust or lower economic status. Further analysis shows that habitat quality and vegetation coverage are key ecological indicators that exert a significant positive moderating effect on the negative impact of rural tourism participation on farmers’ ecological footprints. These findings highlight the importance of integrating ecological conservation with economic development. Accordingly, tailored policies, improved ecological service systems, and enhanced regional ecological quality are recommended to increase resource-use efficiency and promote a virtuous cycle between environmental sustainability and rural economic growth.</div></div>","PeriodicalId":45743,"journal":{"name":"Chinese Journal of Population Resources and Environment","volume":"23 2","pages":"Pages 270-282"},"PeriodicalIF":3.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144696490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is vital to study its development paths, particularly for wind power and photovoltaics, while considering constraints on diffusion potential. Using learning curves, dynamic programming, and Bass models, this study analyzes technological diffusion trends to determine the most cost-effective development route for intermittent renewable energy power generation in China by 2060. This study simplifies reality by examining the individual diffusion processes of wind and photovoltaic power, focusing on the self-diffusion characteristics of the two technologies. The study assumes that self-diffusion is the primary driver of future development and describe the influence of multiple factors. The study finds that supportive policies are key drivers of development in the early stages of intermittent renewable energy deployment, especially for photovoltaics. The current diffusion scale of photovoltaics has a greater positive impact on its future development than that of wind power due to lower costs. In the long term, the phased goal for 2030 is projected to be met ahead of schedule, and the majority of future intermittent renewable energy output is expected to come from photovoltaics. The rapid development phases of photovoltaic and wind power conclude at similar times, but the maximum diffusion potential of photovoltaics is higher than that of wind power. Investment constraints and technological levels affect the initial and middle phases of the development path, but their effects are limited.

To address this, this study uses renewable energy consumption, ICT intensity, FDI, and urbanization as explanatory variables, with carbon dioxide (CO₂) emissions as the dependent variable. The analysis focuses on OPEC members from 2000 to 2020 using a panel vector autoregression (PVAR) method. The results indicate that a shock to FDI, labor force, urban population, and renewable energy consumption reduces CO₂ emissions while a shock to gross capital formation increases them. The impact of an ICT shock on CO₂ emissions is negligible.

Utilizing a resource misallocation model, we construct a new theoretical framework to distinguish between technical and allocative efficiency and analyze productivity using plant-level data. The results indicate that the CLRS policy has significantly improved the allocative and technical efficiency of China’s coal-fired power sector, thereby ensuring power security. The closure of outdated and highly distorted small coal-fired units, which have been replaced by technologically advanced large units, primarily drives the enhanced efficiency. The policy’s effects are most pronounced in large-scale power plants and those with high coal combustion efficiency. Furthermore, a comparison of power plants’ productivity distribution before and after policy implementation reveals that the CLRS policy not only enhances capital productivity in the coal-fired power sector but also increases rational labor allocation.

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.

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.

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.
