New-type urbanization(NTU)is proposed by China to solve unsustainable issues and improve green development efficiency(GDE)during the process of rapid urbanization.However,the impact mechanism of NTU on GDE is unclear.Using panel data of 282 prefecture-level cities in China from 2010 to 2019,we measured NTU and GDE to describe their spatiotemporal pattern and relationship evolution.The fixed effects panel model and mediating effect panel model were further utilized to analyze the benchmark impact,mediating mechanism and spatiotem-poral heterogeneity of NTU on GDE.The results showed that NTU improved,with the highest levels observed in the eastern region,while GDE increased with fluctuations,performing better in both the eastern and western regions.With the proportion of double-high cities increasing from 13.83%to 43.62%,the NTU-GDE relationship was upgraded.Overall,every 1%improvement in NTU increased GDE by 0.3111%,and the enterprise effect,resident effect and government effect played a positive mediating role from high to low.During the later stage of NTU,its impact on GDE strengthened significantly,and the mediating role of governments was optimized.The eastern region was the only region with three positive mediating roles of governments,enterprises and residents.These findings will promote GDE through NTU in China and serve as a valuable reference for sustainable global urbanization. 展开更多

Global sustainable development cannot be achieved by neglecting rural areas.These regions represent vast territorial spaces beyond urban built-up areas,possessing comparative advantages through their distinctive ecological resources.The transformation of ecological resources into economic value,commonly referred to as ecological industrialization,enhances rural economic vitality and developmental potential.Comprehensive rural revitalization strengthens regional functionality and development resilience,thereby promoting sustainable rural development.Based on human-earth system science,we theorize ecological industrialization as the PGR model,manifesting the transformation path from“poor mountain”to“green mountain”and then to“rich mountain”.It is noteworthy that in regions endowed with beautiful ecological landscapes,the PGR model prioritizes the transformation of“green mountain”to“rich mountain”.The essence of rural revitalization manifests through areal transformations driven by tripartite forces:the rural internal force,urban peripheral force,and urban-rural interaction force.There is a mutually reinforcing relationship between ecological industrialization and rural revitalization,and the implementation of the two can realize the coordinated development of rural functions.In this process,rural areas have realized the transformation from degraded land system to human-earth coupling system.Furthermore,through the examination of Fuping,Liuba,and Sanming as exemplary case studies,we have distilled three distinct modes of ecological industrialization:the circular industry mode,the ecological tourism mode,and the carbon sink trading mode.It is recommended that rural areas prioritize the coordinated implementation of ecological industrialization and rural revitalization in accordance with regional characteristics,so as to better foster rural sustainable development. 展开更多

Rural development is an important part of national development in China.However,the lack of rural development degree(RDD)changes and divergence analyses limited our understanding for how to promote rural development in different regions.Therefore,this work introduced a rural development assessment index and equal weighting system,consisting of five dimensions and 25 indicators,to investigate provincial RDD and changes in 2015 and 2021.The results showed that national RDD increased from 0.403±0.066 in 2015 to 0.486±0.054 in 2021 and the scores for each of the five dimensions also improved.China's rural areas had a good development foundation,but rural industrial prosperity and wealthy lifestyle were lagging.Targeted rural development policies promoted provincial-level in-creases in these dimensions.The RDD top-ranked provinces were mainly in eastern China.Most of the bottom-ranked provinces were in central and western China.The top-ranked provinces usually had three or four strong dimensions that supported regional rural devel-opment.However,weak performances in all dimensions were usually observed in the bot-tom-ranked provinces,which limited RDD improvements.The bottom-ranked provinces are encouraged to improve their ecological livability,effective governance,and wealthy lifestyle. 展开更多

Given the great number of studies focusing on the temporal interaction between economic and environmental subsystems, it is useful to perform a quantitative spatial as- sessment of these subsystems. In this paper, comprehensive assessment indicators for re- gional economic development and environmental pollution subsystems are constructed. Then the degree of coupling and coordination of the regional economy-environment system is calculated for 350 prefectural units in China. It is found that the economic development and environmental pollution in most prefectural units is still at a low level of coupling and coordi- nation. According to the coupling and coordination values, the Chinese territory can be di- vided into four types of area: economy-environment harmonious area, economy-environ- ment gearing area, economy-environment rivaling area and low coupling degree of econ- omy-environment area. Based on a structural analysis of the industrial sector in the four types of areas, there is a spatial relationship between the regional industrial sector structure and the coupling-coordination level. In the economy-environment harmonious area, the sectors of manufacturing of high-technology and high value-added products, such as com- munications, computer and electronic equipment, transport equipment and electrical ma- chinery, account for a large proportion of the value of local industrial output. The industrial value of the economy-environment gearing area is concentrated on the manufacturing of machinery and equipment, and. contains a few polluting sectors such as ferrous and non-ferrous metallurgy, chemical manufacturing and electricity generation. The econ- omy-environment rivaling area is the type of area where polluting sectors concentrate, such as iron and steel, petrifaction, coal mining, building materials and electricity generation. In the low coupling degree of economy-environment area, its industry is concentrated on the pro- duction and processing of primary products. 展开更多

Balanced regional development is an important issue in research on development geography. This study reviews the course of balanced regional development in China and summarizes its characteristics in each period. The results show that inter-regional development in China has undergone successive periods of balanced and unbalanced development. Each period has enhanced social development and contributed to a more balanced regional development. This paper discusses the scientific connotation of balanced regional development, and invokes sustainable development theory to argue that we should pay attention to the differences in resource endowments among regions, and solves the imbalance among the economy, humans, and nature to promote the spatial balance of regional development and green development for better coordination between economy and ecology. The balanced promotion of the well-being of people in each region is the ultimate goal of balanced regional development. We then use concepts from development geography to examine China’s path of balanced regional development from the three perspectives of society, the economy, and ecology. Suggestions are also provided for the balanced development of China’s regions and the improvement of public well-being. 展开更多

Newest planning methods implemented by Chinese government are promoting a coordinated regional development and shaping an orderly spatial structure by applying the regulation of territorial function. This article analyzes the problems of spatial planning and regional strategy caused by the wrongly-set primary goal of economic development; it states that the three-fold objective of competitiveness, sustainability, and welfare fairness shall be the principal for China to implement the spatial regulation in the new era; it discusses about theoretical thoughts and technology framework of conducting the ′Major Function Oriented Zone′ based on their different major functions that each region plays in urbanization and industrialization, ecological constructions, grain productions, and protection of natural and cultural heritages; it introduces the new concept of ′Major Function Oriented Zone′ that include the major functions category, the stereo regional equilibrium mode, the two-level zoning specification, and the territorial development intensity; it offers a zoning scheme that defines development-optimized and development-prioritized zones as regions with massive urbanization and industrialization, development-restricted zones as ecological constructing or grain producing regions, development-prohibited zones as natural and cultural heritage protecting regions; and finally it addresses the main obstacle for implementing ′Major Function Oriented Zone′, which is the institutional arrangement of the supreme goal of high GDP growth rate that is currently being implemented. 展开更多

Alleviating the imbalance between urban and rural areas for regional coordinated development is an imperative response to the Sustainable Development Goal 10 of the United Nations.To track China’s urban-rural integration progress and address the uneven issues in specific fields,this study constructed a novel seven-dimension index system of urban-rural integration,comprising free population mobility,efficient land transfer,interactive economic growth,highly-linked transportation,equal public services,joint environmental governance and unimpeded informatization between urban and rural areas.Based on a comprehensive measurement framework and multi-source panel data,we uncovered the spatial-temporal evolution of urban-rural integration in China’s 367 prefecture-level administrative units from 1980 to 2022.The results demonstrated that China’s urban-rural integration steadily increased from 27.51 to 57.35 with an average annual growth rate of 3.40%.Whereas,the overall urban-rural integration was relatively inferior in 2022,at the level of moderate integration whose proportion of China’s land area was 88.08%.The urban-rural integration level in eastern region and urban agglomerations was higher than that in mid-west and non-urban agglomerations.From the perspective of seven dimensions,interactive economic growth,joint environmental governance and unimpeded informatization made an obvious improvement and reached higher integration,while free population mobility,efficient land transfer,highly-linked transportation and equal public services maintained the stage of moderate integration in 2022.In the future,China should make targeted efforts for urban-rural integration in terms of population,land use,transportation and public services,and accelerate urban-rural common prosperity in the mid-west and economically underdeveloped areas. 展开更多

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. 展开更多

Administrative divisions are the important foundation of national governance and social development,and the adjustment of administrative divisions is a critical way to promote regional coordinated development.Under the background of globalization and regionalization,timely adjustment of administrative divisions is a major step to reconstruct the regional development pattern.In the perspective of regional coordinated development,this paper constructs an Administrative Rank Potential Energy(ARPE)model to explore the mechanisms of administrative division adjustment(ADA)under coordinated regional development based on the theory of regional interaction,spatial field energy model and power exponential function.The results show that:(1)The development potential and influence of an administrative region are closely related to the administrative jurisdiction,administrative resources,and the potential of regional coordinated development.(2)The growth rate of ARPE in the study area from 2010 to 2015 was 20.7% compared to the period 2005 to 2010,and the potential for coordinated development increased to 3.05% from 0.21% before the"cancelling"the prefecture-level city of Chaohu.(3)The measurement results of the usefulness of ADA can not only distinguish the complex impacts brought about by social development,but also accord with real social and economic development conditions.The ARPE focuses on the both regional integrated development and individual development,thereby serving as a reference for explaining and evaluating adjustments to administrative divisions at the macro-and micro-scales. 展开更多

The Himalayas,as a global biodiversity hotspot,are crucial for the sustainable development of the Qinghai-Tibet Plateau and South Asia.In this study,the effects of human activity expansion on habitat fragmentation were investigated.Although the encroachment on ecological space in the Himalayas is mainly due to the expansion of cultivated land,in India and Pakistan,human activities affect mainly woodlands,whereas in Nepal and Bhutan,they affect mainly grasslands.Moreover,anthropogenic activities have a more significant impact on agriculture-driven regions such as Nepal,Bhutan,South Xizang,and Sikkim.Finally,the expansion of anthropogenic activities in areas unsuitable for urban and rural development may lead to more severe ecological consequences.Therefore,the expansion of anthropogenic activities in rural areas of the Himalayas warrants careful attention,especially in regions that are not suitable for such development. 展开更多

Cropland suitability analysis is a vital tool for ensuring food security and sustainable agriculture,coordinating ecological space with human activity space on the Qinghai-Tibet Plateau(QTP).However,there are few studies on complete and accurate cropland suitability assessments on the QTP,let alone on identifying key potential areas for cropland development.We used a novel assessment model to generate a 30-m cropland suitability map for the QTP.The identification of areas with cropland development potential and the evaluation of potentially available cropland were further integrated into a unified analytical framework.We found that only 10.18%of the study area is suitable for large-scale and permanent cropland.Moreover,approximately 72.75%of the existing cropland was found to be distributed in suitable or marginally suitable areas.Considering the trade-offs related to irrigation water supply convenience,approximately 1.07%of the study area was identified as having high potential for cropland development.Four key potential areas were further identified:the Shannan Valley,the Nyingchi Valley,the Zanda Valley,and the Gonghe Basin.These areas boast abundant potentially available cropland resources and ecological resettlement capacities,which leads us to recommend strategic priorities for comprehensive land consolidation and water development.This study has practical significance for optimizing land resource allocation and guiding decision-making related to ecological migration on the QTP. 展开更多

As a significant issue, mining cities, especially the resource-exhausted mining cities have already been given intensive attention by academia and government. This article discusses the intrinsic and extrinsic reasons for problems of the mining cities from the perspective of sustainable development, quantitatively analyzes the economic benefit of the mining cities with statistical data, and presents the strategies and measures for sustainable development of the mining cities based on the theoretical discus- sion and empirical study of different types of mining cities. The research shows that: (1) the conflict between the mining cities and the mining enterprises which has been incorrectly dealt with for a long time is the primary reason for the problems of the mining cities. More seriously, the development gap between mining cities and non-mining cities is becoming larger than ever before, due to the domestic and international competition. (2) As a whole, the economic development level of the mining cities is lower than the average level of countrywide cities. The economic benefit of the mining cities is increasing owing to the economic scale, and the economic situations of oil-mining cites and iron-mining cites are relatively better than those of other types of mining cities. (3) The prerequisite of sustainable development of the mining cities is the realization of the transformation of capital superiority so as to promote non-mining economy and substitute the mining economy step by step. 展开更多

Understanding the relationship between China's urbanization and economic de-velopment on a provincial scale is of profound theoretical and practical significance.Based on data from 124 countries or regions throughout the world and 31 provinces or autonomous regions in China,applying improved methods using the quadrant map approach,this paper analyzed the spatial pattern of the relationship between China's urbanization and economic development level.The study identified the following results.(1)The 31 province-level re-gions fall into six categories:only one region is in the category of sharp over-urbanization,3 regions are in medium over-urbanization,11 slight over-urbanization,8 basic coordination,one medium under-urbanization,and seven slight under-urbanization.(2)There are signifi-cant regional differences on a provincial scale in the relationships between urbanization and the level of economic development.(3)The provincial pattern of urbanization and economic development is significantly different between east and west.The eastern coastal areas are mainly over-urbanized,while the central and western regions are mainly under-urbanized.(4)The relationship between urbanization and the level of economic development is similar to the Matthew effect.Hence,two important insights are proposed.First,the phenomenon of over-urbanization in some developed regions should be viewed with some concern and vigi-lance.Second,urbanization needs to be speeded up moderately in the central and western regions. 展开更多

With the introduction of the concept of land use transition into China,related researches have been carried out extensively in the past two decades,which enrich the knowledge of land system science.This paper describes the development of research on land use transitions in China from the perspectives of conceptual connotations,theoretical model,research methods,and research progress and prospects.With the in-depth investigation of land use transitions,the concept and connotations of land use morphology are developed and encapsulated as two kinds,i.e.,dominant morphology and recessive morphology.The dominant morphology refers to the land use structure of a certain region over a certain period of time,with features such as the quantity and spatial pattern of land use types.While the recessive morphology includes the land use features in the aspects of quality,property rights,management mode,input,output and function.Accordingly,the concept of land use transition is further developed,and the theoretical model of regional land use transitions is established.Thereafter,three innovative integrated approaches to study land use transitions are put forward,i.e.,multidisciplinary research framework for recessive land use transition,transect and horizontal comparison.To date,there have been 62 Ph.D.and 166 M.S.dissertations on the topic of"land use transition"in China.During 2002–2019,the National Natural Science Foundation of China has funded 48 research programs on the theme of"land use transition".As such,the Chinese scholars have adapted the concept derived from western literature to the situations and experiences in China. 展开更多

Transport infrastructure plays an important role in shaping the configuration of spatial socio-economic structures and influencing regional accessibility. Although China＇s transport infrastructure has been experiencing a rapid development in the last 100 years, there lacks a systematic examination of the complete evolution history of China＇s transport development, particularly with all kinds of transport modes. This paper first aims to clarify the history of China＇s transportation from 1910 to 2012, and divides its evolution process into five periods （1911, 1935, 1953, 1981 and 2012） whereby each period represents the preliminary development time for each transport mode. Second, the paper calculates the transport dominance and analyses its spatial distribution in each period, with county as the basic analysis unit. Transport dominance here is defined as an integrated indicator for evaluating regional transport conditions. The results demonstrate the following： （1） areas with relative good transport dominance have expanded from scattered dots such as Tianjin, Shanghai, Guangzhou in 1911 to extensive areas with each provincial city as cores in 2012; （2） transport development is improved by advances in transportation technology. The construction of modern transport infrastructures such as seaports, airports, high-speed rails （HSRs）, and freeways lead the expansion of national territorial areas with good and excellent transport dominance and the increase of the value of transport dominance over time; （3） transport dominance is spatially unevenly distributed and exhibits resemblance with the expansion of transport network, which is closely related to China＇s socio-economic development and policles. 展开更多

Urbanization and Sustainable Development Goals(SDGs)are important global issues in the current“Anthropocene”.Climate change and the COVID-19 pandemic have exacerbated global urban problems and hindered the ability to meet SDGs on time,while the broad interlinkages between urbanization and the SDGs remain poorly understood.This study shows that among the interlinkages of urbanization with 17 SDGs,synergies are observed with 151 targets(89%),among which 67(40%)have stronger synergies,and trade-offs are observed with 66 targets(39%),among which 31(18%)have stronger trade-offs.Furthermore,the synergies and trade-offs between urbanization and the achievement of SDGs are specifically analyzed based on four fundamental interaction fields:(a)public health and social welfare equality;(b)energy consumption and economic growth;(c)natural resource use and ecological/environmental impacts;and(d)international cooperation for development.Finally,based on these analyses,we propose four recommendations for sustainable urbanization,including(a)shared well-being and spatial justice for urban and rural residents;(b)guiding green and low-carbon urban development;(c)building resilient cities;and(d)promoting multilateral cooperation in cities,which can contribute to the achievement of SDGs by 2030. 展开更多

The Chinese government ratified the Paris Climate Agreement in 2016.Accordingly,China aims to reduce carbon dioxide emissions per unit of gross domestic product(carbon intensity)to 60%–65%of 2005 levels by 2030.However,since numerous factors influence carbon intensity in China,it is critical to assess their relative importance to determine the most important factors.As traditional methods are inadequate for identifying key factors from a range of factors acting in concert,machine learning was applied in this study.Specifically,random forest algorithm,which is based on decision tree theory,was employed because it is insensitive to multicollinearity,is robust to missing and unbalanced data,and provides reasonable predictive results.We identified the key factors affecting carbon intensity in China using random forest algorithm and analyzed the evolution in the key factors from 1980 to 2017.The dominant factors affecting carbon intensity in China from 1980 to 1991 included the scale and proportion of energy-intensive industry,the proportion of fossil fuel-based energy,and technological progress.The Chinese economy developed rapidly between 1992 and 2007;during this time,the effects of the proportion of service industry,price of fossil fuel,and traditional residential consumption on carbon intensity increased.Subsequently,the Chinese economy entered a period of structural adjustment after the 2008 global financial crisis;during this period,reductions in emissions and the availability of new energy types began to have effects on carbon intensity,and the importance of residential consumption increased.The results suggest that optimizing the energy and industrial structures,promoting technological advancement,increasing green consumption,and reducing emissions are keys to decreasing carbon intensity within China in the future.These approaches will help achieve the goal of reducing carbon intensity to 60%–65%of the 2005 level by 2030. 展开更多

With the global economy increasingly dependent on innovation,urban discourse has shifted to consider what kinds of spatial designs may best nurture innovation.We examined the relationship between the built environment and the spatial heterogeneity of regional innovation productivity(RIP)using the example of China's Pearl River Delta(PRD).Based on a spatial database of 522546 patent data from 2017,this study proposed an innovation-based built environment framework with the following five aspects:healthy en-vironment,daily interaction,mixed land use,commuting convenience,and technology atmosphere.Combining negative binomial regression and Geodetector to examine the impact of the built environment on RIP,the results show that the spatial distribution of innovation productivity in the PRD region is extremely uneven.The negative binomial regression results show that the built environment has a significant impact on the spatial differentiation of RIP,and,specifically,that healthy environment,mixed land use,commuting convenience,and technology atmosphere all demonstrate significant positive impacts.Meanwhile,the Geodetector results show that the built environment factor impacts the spatial heterogeneity of RIP to varying degrees,with technology atmosphere demonstrating the greatest impact intensity.We conclude that as regional development discourse shifts focus to the knowledge and innovation economy,the innovation-oriented design and updating of built environments will become extremely important to policymakers. 展开更多

To tackle the issues concerning agriculture,farmers,and rural areas,the central government of China initiated a new strategy called'new countryside construction'in 2005.For better understanding its actual effect,this paper analyzes the regional diversity of peasant household response to this new countryside construction strategy based on Kruskal-Wallis H test and sampling survey data from 586 households in the Bohai Rim Region(BRR),Yangtze River Delta Region(YDR),and Pan Pearl River Delta Region(PPR).The result indicates that regional diversity in eastern coastal China(ECC)does exist in the form of recognized priority sequence,policy requirements,expected policy effects,and behavior response.As a result of the deviation between local policy practice and households'inherent demand,peasants fulfill their de facto demand via individual effort instead of government aid,and therefore the new countryside construction fails to carry out the expected target.It thus needs to shift the current policy priority,ensure the peasants'mainstay role,and formulate scientific'Rules for new countryside construction'. 展开更多

As one of the five most important spheres affecting climate systems globally, the cryosphere not only exerts crucial impacts on natural environment, but also plays a key role in guaranteeing the goods and services provision of the oasis in the cold and arid regions. However, there is a lack of synthesized knowledge about the contributions and profitability on socio-economic aspects of the cryospheric services (CSs). To cope with this key and urgent sustainable development issues, this study constructs a comprehensive regionalization research system that integrates the natural and socio-economic aspects for cryospheric characteristics with emphasis on interdisciplinary approaches. Guided by the supply- demand equilibrium model and the service maximization model, the research system consists of establishing a classification system for CSs, identifying the spatial distribution pattern of CSs, and constructing the comprehensive regionalization of CSs, which finally divides the research area into relatively independent, complete, and organically linked CS units of multiple spatial levels. By setting up a bridge between the CSs with socio-economic needs, it has profound and practical significance and implications for implementing the sustainable utilization strategies and macroeconomic policymaking for global environmental protection. 展开更多
