文摘Urban areas’performance in water,energy,infrastructure,and socio-economic sectors is intertwined and measurable through Sustainable Development Goals(SDGs)6–13.Effective synergy among these is critical for sustainability.This study constructs an indicator framework that reflects progress towards these urban SDGs in China.Findings indicate underperformance in SDGs 8–11,suggesting the need for transformative actions.Through network analysis,the research reveals complementarities among these SDGs.Notably,the SDG space divides into socio-economic and ecological clusters,with SDG 6(Clean Water and Sanitation)central to both.Additionally,SDG 8(Decent Work and Economic Growth)and SDG 9(Industry,Innovation,and Infrastructure)act as bridges,while greater synergies exist between SDG 12(Responsible Consumption and Production)and SDG 13(Climate Action).An in-depth view at the indicator-level shows a core-periphery structure,emphasizing indicators like SDG 6.2(Wastewater Treatment Rate)and SDG 6.6(Recycled Water Production Capacity per capita)as pivotal.This study confirms the urban SDG space’s stability and predictiveness,underscoring its value in steering well-aligned policy decisions for sustainable growth.

文摘Economic growth and fair distribution are two major goals pursued in economic development.Through a comparative analysis of economies such as those in Europe and the United States,it is found that:Economic growth does not have to be conditional on the expansion of income gap;growth will not automatically lead to fair distribution;efficiency and fairness can occur simultaneously;the transformation of the economic development mode can be achieved through income distribution.A shared development model that takes into account both growth and fairness is the choice to achieve sustained and stable economic growth.It is necessary to deepen the reform of the income distribution system,improve social security and other measures to promote the development achievements to benefit the majority of workers more,and achieve both efficiency and fairness at the same time.

文摘Dongyuemiao Member shale in the Sichuan Basin,China,is characterized by organic-rich shale intervals with different types of interbeds and accumulation modes.The aim of this study is to elucidate the impact of paleoenvironmental indicators on interbed development.With this aim in mind,we established an interbed classification scheme and quantified the development of different types of interbeds and their frequencies.We categorized the shale interbeds into three types based on interbed type:silt interbeds(SIs),shell fragment interbeds(SFIs),and shell skeleton interbeds(SSIs).The SIs,SFIs,and SSIs are respectively the products of extrabasinal low-density turbidity currents,intrabasinal debris flow,and intrabasinal low-density turbidity currents.We propose that variations in paleoenvironmental conditions primarily influenced the types of interbeds that developed but had minimal impact on the frequency of their development.Models depicting the interbed development within the 1st Submember of Dongyuemiao Member indicate that during the early Dongyuemiao depositional period,under conditions of relatively aridity,weak weathering,high terrigenous input,and strong hydrodynamic activity,SSIs were well developed.In the middle depositional period,as the climate gradually transitioned to more humid conditions,and the weathering intensity and amount of terrestrial input increased,the development of SIs and SFIs significantly increased.During the late depositional period,with a continuous decrease in terrestrial inputs and sedimentation rates,the development of SIs decreased while that of SSIs increased.

文摘China has achieved the poverty reduction goal of the United Nations 2030 Agenda for Sustainable Development 10 years ahead of schedule,contributing significantly to global poverty reduction.Despite extended efforts in poverty elimination,there is a lack of quantitative studies categorizing and comparing poverty-elimination counties(PECs)based on their processes.This study proposes an innovative framework for analyzing PECs’development paths from the perspective of population-land-industry(PLI).We quantify the PLI matching degree of PECs in China during the critical phase of the battle against poverty through a multivariate matching model,classify PECs via K-means clustering according to the consistency in PLI matching degree evolution,and summarize the typical development patterns of PECs.Results indicate that the PLI matching degree of PECs in China increased substantially from 2015 to 2020,particularly in eastern areas,while the western region,including the Qinghai-Xizang Plateau and southwestern Xinjiang,shows untapped potential for improvement.Five types of PECs are identified,with the majority(30.1%)showing sustained moderate PLI matching and a minority(9.6%)experiencing long-term PLI mismatch.Industry is the shortfall of various PECs,and effective strategies to facilitate all types of PECs include the development of emerging businesses and the expansion of secondary and tertiary industries.Additionally,enriching rural labor force and increasing farmland use efficiency are essential for optimal PLI matching and positive interaction,ultimately ensuring poverty elimination and sustainable development.

文摘The Chinese government promises to reach the carbon emission peak by 2030 and achieve the carbon neutrality by 2060.Renewable energy development is important for achieving this target.Local governments’behaviors and attitudes might be influenced by neighbors.Therefore,this study uses simultaneous autoregressive models(SAR)to examine the peer effects on renewable energy development across China’s provinces and explain the imbalanced renewable energy developments across regions in China.The results exemplified:①The peer effects exist in China and the endogenous interaction is the main cause.②The interaction between geographically adjacent provinces have greatest peer effects.③Both competition mechanism and learning mechanism induce the peer effects and the imbalanced development.This research introduces energy-related peer effects at the provincial level to reflect the preferences of governments and reveal the underlying mechanisms involved.It also provides suggestions to policy makers:①Select developed provinces as the frontrunner to promote the renewable energy development in neighboring areas.②Regional renewable energy development policies need to be considered.③Central government should consider adding“green growth indicators”into evaluation system to avoid the asymmetrical incentives policies between economic growth and environmental protection.
