The present study constructed the 2023Cross-City Patient Mobility Network in China using one million patient mobility data records obtained from online healthcare platforms. We applied urban network analysis to uncover mobility patterns and used the coupling coordination degree model to assess healthcare supply-demand relationships before and after patient mobility. Explainable machine learning further revealed the impact of supply-demand coupling on patient mobility. The results indicated the following: Patient mobility followed administrative boundaries, although megacities serve areas beyond provincial borders;The scale of healthcare supply and demand displayed a multi-centric spatial pattern with a general decline from east to west, and these characteristics of demand distribution were further solidified by patient mobility;Cities with low supply-demand coupling and undersupply experienced patient outflows, while cities with high coupling and oversupply attracted them. In turn, patient mobility helped balance healthcare supply and demand, optimising the coupling relationship across cities. Thus, this research not only provides a methodological reference for understanding the interaction between patient mobility and healthcare systems but also offers empirical insights for public health policy.展开更多

The eco-economic system can be divided into socioeconomic and ecological sub-systems and their relationship can reveal the interaction state between the two sub-systems and help the local government to establish a coordinated development mode. An index system was constructed to assess the development of the two sub-systems before the evaluation of the degree of coupling and coordination. The principal component regression analysis was adopted to quantitatively assess the influences of natural, economic and social factors on the degree of coupling and coordination of the eco-economic system. Results showed that, from 1983 to 2014, the development trends of both sub-systems were increasing with the ecological sub-system having more fluctuations. The degree of coupling and coordination of the eco-economic system in the study area increased gradually from 1983 to 2014, but experienced five different development stages from the verge of disorder to favorable coordination. The development of the local social and economic conditions was the most important factor influencing the degree of coupling and coordination. The second most important factor was the financial support from the local government. In addition, the environment protection policies also played undeniable roles. Due to the diversity of the influence factors, the government should take comprehensive measures to promote the sustainable development of the eco-economic system.展开更多

An evaluation index system was constructed,and index weights were obtained using the variation coefficient method. The traffic volume was found to be the main factor contributing to transport superiority degree, and space urbanization was the primary factor influencing comprehensive urbanization. The coupling degree between transport superiority degree and urbanization( CU) was generally higher than the coupling coordination degree( DU) in 2000-2011. DUvaried more significantly than CU. In 2011, Sichuan was divided into five regional types. Based on the above observations, targeted recommendations were developed.展开更多

Firstly, the regional science and technology innovation ability is divided into two parts： innovation input and innovation transformation result. The accumulation of knowledge outside the region is introduced as a variable influencing the correlation effect, and the index system of regional innovation capability is constructed. According to the degree of coordination between the regional technological innovation ability and the level of industrial agglomeration, the Yangtze River economic belt provinces and municipalities are divided into moderate disorder class, serious disorder class, extreme disorder class, middle and lower reaches of the Yangtze River region interregional knowledge accumulation weak.展开更多

文摘The uneven distribution of medical resources has led to increasingly frequent patient mobility;however, the interaction between this phenomenon and the healthcare supply-demand relationship remains underexplored. The present study constructed the 2023Cross-City Patient Mobility Network in China using one million patient mobility data records obtained from online healthcare platforms. We applied urban network analysis to uncover mobility patterns and used the coupling coordination degree model to assess healthcare supply-demand relationships before and after patient mobility. Explainable machine learning further revealed the impact of supply-demand coupling on patient mobility. The results indicated the following: Patient mobility followed administrative boundaries, although megacities serve areas beyond provincial borders;The scale of healthcare supply and demand displayed a multi-centric spatial pattern with a general decline from east to west, and these characteristics of demand distribution were further solidified by patient mobility;Cities with low supply-demand coupling and undersupply experienced patient outflows, while cities with high coupling and oversupply attracted them. In turn, patient mobility helped balance healthcare supply and demand, optimising the coupling relationship across cities. Thus, this research not only provides a methodological reference for understanding the interaction between patient mobility and healthcare systems but also offers empirical insights for public health policy.

文摘Vegetation ecological quality(VEQ)is not only influenced by meteorological drought(MD)but also exerts a certain degree of regulatory effect on it.Clarifying the relationship between the two is crucial for ecological conservation efforts.However,the interactions between VEQ and MD and its driving mechanisms in karst mountain regions with high surface heterogeneity remain unclear,and the lack of exploration of this interaction under different subregions hinders further progress in ecological conservation.This study took Guizhou Province,characterized by significant surface heterogeneity and extensive karst formations,as a research case.By dividing the region into different landform regions,we quantified the coupling coordination degree(CCD)between VEQ and MD using the coupling coordination degree model to elucidate their interaction and analyzed its driving forces using the Geodetector model.Results indicated that:(1)From 2001 to 2020,the CCD between VEQ and MD in Guizhou remained at a moderate coordination level,with increasing benign interactions,though significant variations in CCD trends were observed across landform regions.MD is the pivotal subsystem that determines CCD changes.(2)The dominant driving factors of CCD vary by landform,with soil moisture,precipitation,or population density as primary influences.Soil moisture has a stronger effect in karst regions,and its interaction with other factors surpasses the effects of individual factors.(3)To achieve benign development between VEQ and MD.In karst regions,attention should be focused on the impact of soil moisture and human activities on CCD.While non-karst regions have favorable vegetation and hydrothermal conditions,improper development can lead to vegetation degradation,and abnormal hydrothermal conditions,which could trigger a decline in CCD.Therefore,regulating human activities in non-karst regions is also crucial.This work serves as a scientific foundation for formulating ecological preservation strategies in Guizhou and other karst mountain regions.

文摘In this paper,the Taixin Integrated Economic Zone in Shanxi Province is taken as the research object,and the coupling coordination degree model and bivariate spatial autocorrelation model are used to judge the coupling coordination and spatial-temporal correlation between urbanization and ecosystem service,and the hotspot analysis is used to judge the spatial-temporal trend of urbanization and ecosystem service.The results show that:(1)The urbanization level from 2000 to 2020 continued to rise,the areas with relatively high urbanization were concentrated in the central part of the study area,and the relatively high terrain areas on both sides of the study area,the urbanization was relatively slow,and the hotspot areas with highly significant and significant urbanization level from 2000 to 2020 were distributed as bands in the central part of the study area and the area was rising,and there was no Cold spot area distribution;between 2000 and 2020,the ecosystem service value in the study area increased by 2.6800×10^(8) yuan.Over these two decades,it exhibited a development trend that first rose and then declined.The woodland and grassland agglomeration areas were located on the two sides of the study area,forming highly significant and significant hotspots.Conversely,the central and northeastern parts of the study area were characterized by concentrated man-made land surfaces and croplands,resulting in the formation of highly significant and significant cold spots.(2)In the central part of the study area where man-made land surface and cultivated land are concentrated,the coupling coordination between urbanization and ecosystem service is in the intermediate dislocation and mild dislocation interval;the woodland and grassland concentration areas on both sides of the study area are ecologically fragile,and the coupling coordination between the two is in the level of less than intermediate dislocation.(3)From 2000 to 2020,urbanization and the value of ecosystem services were both negatively correlated,although the correlation coefficient was low.In the central and northeastern parts,urbanization and ecosystem service exhibited patterns of high-low,high-high,and low-low clustering.Conversely,on both sides of the study area,most of the clusters showed a low-high pattern.

文摘Rural resilience,a core capability for addressing systemic risks and enabling sustainable development,is increasingly vital to promoting urban-rural integrated development and rural revitalization strategies.However,current research lacks exploration of the collaborative mechanisms between rural economic resilience(RER)and rural social resilience(RSR)in ecologically vulnerable areas.Based on the practical context of rural sustainable development in such regions,this study investigates the interaction between RER and RSR from a resilience coordination perspective.In this paper,a rural resilience evaluation framework for collaborative development of economic and social resilience was established.By employing the coupling coordination degree model,obstacle degree model,and equilibrium entropy model,this paper examines the synergies,constraints,and potential of rural resilience subsystems in Jinchang City,Gansu Province,China,in 2020.The results reveal that:1)RER contributes to RSR by stabilizing the economy,enhancing community adaptability,and driving modernization.In turn,RSR strengthens RER by mitigating instability,building social capital,and fostering confidence—together forming a mutually reinforcing coupling mechanism.2)The rural economic and social resilience level in Jinchang City remains generally low with spatially clustered patterns,while the coupling coordination degree is at an intermediate level overall,with 62.59%of villages exhibiting unbalanced development between rural economic and social resilience.3)RER and RSR demonstrate synergistic degradation in ecologically vulnerable areas,where low-level rural economic and social resilience induce integrated systemic deterioration.4)Considering the unbalanced development of rural economic and social resilience in ecologically fragile areas,differentiated coordination pathways are proposed for three village typologies:RER-lagging villages,RSR-lagging villages,and villages where RER and RSR develop synchronously but lack effective coordination.These findings offer spatial governance strategies and practical guidance for enhancing rural resilience and advancing sustainable development in ecologically vulnerable regions.

文摘Agricultural insurance plays a key role in promoting the coordinated development of green agriculture and farmers’income growth,which is crucial for China’s high-quality agricultural development.Using the coupling coordination degree model,this study empirically demonstrates that the development of agricultural insurance significantly promotes the coordinated development of green agriculture and farmers’income growth once a certain threshold is exceeded.This effect is more pronounced in the major grain-producing regions and the central provinces.Expanding the scale of agricultural production and increasing investment in agricultural technology are the key mechanisms through which agricultural insurance supports the dual goals of green agriculture and income growth in China.In conclusion,this study proposes several policy recommendations,which include increasing investment in agricultural insurance infrastructure,strengthening the policy guidance for agricultural insurance,and designing differentiated agricultural insurance policies.

文摘The relationship between socioeconomic development and the environment is intimately linked with the level of regional sustainable development.Clarifying the evolution pattern of this relationship during the sustainable development progress is crucial for achieving all of the Sustainable Development Goals(SDGs),but less research has focused on this problem.Here,we have utilized statistical and remote sensing data from 290 municipal units in China to analyze the evolution of the coupling coordination degree(CCD)between socioeconomic development and the environment along a progression of sustainable development measured by the SDG Index.The results show that the hotspot areas of CCD are concentrated in coastal regions,gradually decreasing as they move inland.Additionally,as sustainable development progresses,both socioeconomic and environment levels exhibit a nonlinear rise.The coupling coordination between the two demonstrates a pattern of initial increasing,then decreasing,and finally increasing again,which may be related to changes in industrial structure.Our study delves deeply into the patterns of evolution in the relationship between socioeconomic and environments,exploring the challenges and opportunities faced by regions at different stages of sustainable development.The findings can deepen our understanding of sustainable development and provide policy suggestions and theoretical support for achieving SDGs.

文摘Based on the statistical data, we analyzed and evaluated the degree of coupling and coordination of the eco-economic system in Yanchi County for the period spanning from 1983 to 2014. The eco-economic system can be divided into socioeconomic and ecological sub-systems and their relationship can reveal the interaction state between the two sub-systems and help the local government to establish a coordinated development mode. An index system was constructed to assess the development of the two sub-systems before the evaluation of the degree of coupling and coordination. The principal component regression analysis was adopted to quantitatively assess the influences of natural, economic and social factors on the degree of coupling and coordination of the eco-economic system. Results showed that, from 1983 to 2014, the development trends of both sub-systems were increasing with the ecological sub-system having more fluctuations. The degree of coupling and coordination of the eco-economic system in the study area increased gradually from 1983 to 2014, but experienced five different development stages from the verge of disorder to favorable coordination. The development of the local social and economic conditions was the most important factor influencing the degree of coupling and coordination. The second most important factor was the financial support from the local government. In addition, the environment protection policies also played undeniable roles. Due to the diversity of the influence factors, the government should take comprehensive measures to promote the sustainable development of the eco-economic system.

文摘Relationship between transport superiority degree and urbanization is not quantified enough in recent researches.Combined with coupling model and coupling coordination model,the spatial analysis technique was applied to quantitatively analyzing the relationship between transport superiority degree and comprehensive urbanization in eighteen prefecture-level cities in Sichuan from 2000 to 2011. An evaluation index system was constructed,and index weights were obtained using the variation coefficient method. The traffic volume was found to be the main factor contributing to transport superiority degree, and space urbanization was the primary factor influencing comprehensive urbanization. The coupling degree between transport superiority degree and urbanization( CU) was generally higher than the coupling coordination degree( DU) in 2000-2011. DUvaried more significantly than CU. In 2011, Sichuan was divided into five regional types. Based on the above observations, targeted recommendations were developed.

文摘Due to limited resources regarding port development,the contradiction between ports and cities has gradually become prominent.Taking China's coastal ports as an example,this paper measures the degree of coordination between port development and urban environment,and analyzes its influencing factors.We find that this coordination degree is relatively low and needs to be further improved.The regression results of the ordinary panel model show that the scale of port logistics,port infrastructure construction,and the quality of economic development play a significant role in promoting the coordinated development of the port and the urban environment.The regression results of the threshold panel model show that the expansion of the port logistics scale is only conducive to promoting the coordinated development of the port and the urban environment when the levels of port infrastructure are relatively high.In addition,the promotion effect of the port logistics scale on the coordinated development of the port and the urban environment differs depending on the quality of economic development.Therefore,the relevant departments should pay more attention to the construction of port infrastructure and the quality of economic development,making appropriate adjustments to both in order to better promote the coordinated development of the port and city environment.

文摘The development status of China's marine industry in recent years was qualitatively analyzed,and it is found that the scale of China's marine economy continued to expand,and the industrial structure has been continuously optimized.Then,the coupling and coordination degree between the development of marine industry and the gathering of marine talents were analyzed quantitatively,and it is found that the development of marine industry generally promoted the gathering of marine talents,but the promotion of each industry was weak.The influence of the development of marine industry on the gathering of marine talents should be strengthened.It is proposed that the development of marine industry should be promoted from the aspects of strengthening the planning level of industrial development,improving the efficiency of resource allocation,promoting the innovation and development of marine industry,and strengthening the management of marine talents,so as to enhance the influence of marine industry on the gathering of marine talents and form a benign interaction between talents and industry.
文摘Based on principal component analysis, coordinated development model and location entropy, this paper analyzes the coordinated development of regional scientific and technological innovation ability and industrial agglomeration level and the spatial differences in Yangtze River economic zone. Firstly, the regional science and technology innovation ability is divided into two parts： innovation input and innovation transformation result. The accumulation of knowledge outside the region is introduced as a variable influencing the correlation effect, and the index system of regional innovation capability is constructed. According to the degree of coordination between the regional technological innovation ability and the level of industrial agglomeration, the Yangtze River economic belt provinces and municipalities are divided into moderate disorder class, serious disorder class, extreme disorder class, middle and lower reaches of the Yangtze River region interregional knowledge accumulation weak.

文摘Urbanization interacts with land use through resource consumption and space en-croachment.Clarifying the spatial correlations of the interactive relationship between urbaniza-tion and land use,along with their spatiotemporal dynamics,is of vital importance for address-ing the complex interplay between urban development and land resources and identifying re-gional differences.However,previous studies have not sufficiently explored these issues.Herein,we introduce a coupling coordination degree(CCD)model and present the results of exploratory spatiotemporal analyses involving in-depth investigation of the CcD between ur-banization quality and land-use intensity in 290 Chinese cities.The results demonstrate that the CcD for most cities was at the transition-period or basic-coordination stage.The dynamics of the spatial correlation of the CCD was found to increase from the east to the central and west-ern regions,but this was found to decline overall.The movement direction and spatial de-pendence of the local spatial structure of the CcD exerted a dominant synergistic effect.The transition of the spatial correlation was mainly Type I(stable local and neighboring morphology),showing strong transfer inertia,path dependence,and locking features.Dynamic transitions occurred more in central and eastern cities.The results suggest that more cross-city coopera-tion could contribute to moderate land-resource exploitation for high-quality urbanization.

文摘One of the greatest challenges in the agroecosystem is to improve cropland intensification while preserving agroecosystem services.While many studies have investigated the effect of cropland intensification on agroecosystem service,the interactive coupling and coordination among these factors remain largely unexplored.In view of this,this study performed a case study of the Loess Plateau in Shaanxi Province,China and constructed comprehensive evaluation models to quantify the cropland intensification and agroecosystem service in this area.Balance analysis and the coupling coordination degree model were used to evaluate the interactive relationship between cropland intensification and agroecosystem service,and statistical analysis and spatial autocorrelation were used to analyze the spatial characteristics and potential mechanism of the coupling coordination.Results show that both the cropland intensification and agroecosystem service in the study area were relatively low yet gradually increased from 2000 to 2020.Agroecosystem service lag was identified as the dominant unbalanced development type.Improving the supply capacity of agroecosystem services plays a key role in the balanced development of cropland in the Loess Plateau.The coupling coordination degree between cropland intensification and agroecosystem service ranges from basic coordination to serious incoordination.Therefore,cropland intensification practices in the area should be optimized to enhance this coordination degree.An upward trend was also observed in the coupling coordination degree from2000 to 2020.The withdrawal of marginal cropland in the Grain for Green program is one of the most important reasons for this trend,especially for the northern region.Around 83.6%of the high-high clusters are concentrated in the southern region of the Loess Plateau,whereas 70.5%of the low-low clusters are distributed in the northern region.These clustering characteristics are mainly attributed to the environmental suitability of these areas for agriculture and their degree of economic development.

文摘In China,the Innovation Demonstration Zone for the National Sustainable Development Agenda is a key initiative for executing the United Nations(UN)2030 Agenda for Sustainable Development.The Zone also plays critical roles in addressing the developmental bottlenecks that China faces and sharing Chinese insights into global sustainable development efforts.On July 15,2022,the State Council endorsed the Zone’s establishment in Zaozhuang City,Shandong Province,where it focuses on innovation-led sustainable development in rural areas.Research into the levels,impediments,interdependencies,and evolutionary trends of rural sustainable development is crucial.Therefore,this research aimed to assist in comprehensively assessing developmental challenges and facilitating the harmonious advancement of social,economic,and environmental aspects in rural areas.In pursuit of the three fundamental dimensions of the UN’s Sustainable Development Goals(SDGs),namely development’s drivers,quality,and equity,this study was grounded in China’s national Rural Revitalization Strategy and the demands of sustainable development strategies.It also aligns with the UN 2030 Agenda for Sustainable Development and the associated SDG indicators.Focusing on four key areas,namely production elements,natural elements,social elements,and rural governance,this study developed an evaluation index system for assessing the level of rural sustainable development.It employed a range of analytical models,including the game theory-based combination empowerment method,barrier degree model,coupling degree model,coupling coordination degree model,and gray prediction GM(1,1)model,to analyze the status and evolving trends of rural sustainable development in Zaozhuang City from 2015 to 2022.The key findings were as follows:①Relative to the baseline year 2015,the sustainable development level in Zaozhuang’s rural areas has shifted toward an improved state overall.②The primary barrier to achieving rural sustainable development in Zaozhuang is the city’s rural governance system.③While the components of rural sustainable development in Zaozhuang are in the early stages of both basic and moderate coordination,an overall enhancement has occurred in their integrative coordination.④Between 2023 and 2025,the level of integrative coordination in Zaozhuang is expected to rise steadily.However,reaching a state of advanced coordination will require additional time for development.
