low-carbon city pilot;the green utilization efficiency of urban land;propensity score matching difference-in-differences method;policy evaluation
摘要：
China has implemented the low-carbon city pilot (LCCP) policy in the hopes of efficiently limiting carbon emission intensity to combat global warming and promote green economic growth. Urban land utilization, the second-largest source of carbon emissions, is key to the LCCP policy being able to have the desired effect, which has attracted widespread attention. Based on the panel data from prefecture-level cities in China from 2006 to 2019, this study used the propensity score matching difference-in-differences method (PSM-DID) to examine the impacts of LCCP policy on green utilization efficiency of urban land (GUEUL). The results reveal that LCCP policy has a beneficial impact on GUEUL and can effectively boost the future possibilities of green and low-carbon city development. Due to variances in regional economic and resource endowment level, the impacts of LCCP are different. The pilot has pushed GUEUL in the eastern region, western region, and growing resource-based cities, but has failed to improve GUEUL in other regions. Policymakers should adhere to the long-term sustainability of the LCCP policy and adopt differentiated action strategies to promote GUEUL when implementing it in different regions.

摘要：
Primary education services are a key component of public infrastructure. These services exert significant impacts on public activity, sustainability, and healthy socio-economic development. This research applies the concept of a 'living circle' in order to evaluate the spatial equilibrium of education services in existing primary schools. This has enabled equilibrium planning schemes to be proposed for primary schools as well as the promotion and construction of livable and defensible living spaces. This area remains a key issue, however, one that urgently needs to be addressed in terms of the layout of public infrastructural services to facilitate livable living space construction. Thus, from the perspective of livable and defensible living space construction, the aim of this study was to construct a primary education equalization assessment method based on the walking living circle method. An equilibrium index was also designed based on the number of primary school students; this was then combined with the standard construction of new primary schools to optimize the spatial equilibrium of these education services. The city of Zhangjiakou City was then used as a case study; the spatial equilibrium of primary education services was evaluated across four living circle scenarios (i.e., 15 min, 20 min, 25 min, and 30 min). Results reveal that the city of Zhangjiakou currently offers dramatically spatially negative non-equilibrium primary education services (i.e., supply < demand) across four living circle scenarios, but most notably in rural areas away from urban areas and towns, especially in the counties of Shangyi, Chicheng, Chongli, Kangbao, and Guyuan. It is interesting to note that all living circle scenarios could enable positive non-equilibrium primary education services (i.e., supply > demand), mainly within the urban districts of Qiaodong, Xuanhua, Qiaoxi, Wanquan, and Xiahuayuan. It is also clear that equilibrium living circles are distributed across all counties. A spatial optimization proposal for primary school services should therefore be presented that alleviates the issues inherent to non-equilibrium primary education services. The results of this study offer a number of suggestions for education service optimization across the city of Zhangjiakou as well as for other cities in China. We also provide further scientific foundations for research on livable space and defensible unit construction as well as the spatial equilibrium evaluation of other public infrastructural service facilities
摘要：
In rural poverty governance, one of the most significant challenges faced by developing countries is to reduce the negative impact of economic growth fluctuations on poverty reduction, so as to achieve a win-win situation of “economic growth and poverty reduction”. Based on the provincial-level panel data and data of poverty-stricken counties from 2000 to 2016 in China, this paper evaluates the poverty reduction effect of rural public expenditure from the perspectives of cyclical fluctuation and spatial spillover by using the instrumental variable method. It was found that rural public expenditure is pro-cyclical, and after exclusion of the cyclical factors, the essence of fluctuations is still pro-cyclical. Further research also shows that rural public expenditure has a significant spatial spillover effect on poverty reduction, which is even greater than the direct effect. Based on these findings, the policy implications can be that it is critical to provide moderate-scale and stable rural public expenditure, and establish a multi-level and differentiated agricultural insurance system supported by the government. This paper reveals the spatial interaction mechanism between public expenditure and poverty reduction, and also provides reference for correct evaluation of the economic growth and poverty reduction in developing countries.

摘要：
The green transition of farmland use is a future trend in China’s modern agriculture and green development. However, its research framework, including its evaluation system, temporal-spatial distribution, and driving mechanisms, has not been established in the existent literature. With the 17 cities in Hubei Province as an example, we evaluated the green transition of farmland use and explore the characteristics and driving mechanisms of the temporal and spatial evolution from 2000–2019. The findings were as follows: First, the green transition of farmland use in Hubei Province is in infancy, but it has great potential. Second, the growth rate of the green transition of farmland use has noticeable regional differences in the east, central, and western areas of the province. Third, the three dimensions of spatial transition, functional transition, and model transition in the green transition of farmland use have significant spatial differences in coupling and coordination, and decoupling is becoming increasingly prominent. Based on the research findings, we put forward targeted countermeasures and suggestions.

摘要：
Climate change, urbanization, and industrialization have caused severe conflicts in land use functions (LUFs) in Chinese ecologically fragile areas. The coordination of LUFs is of great significance to optimize national territory space. This study proposes an index system to assess LUFs and their conflict/coordination relationship at the grid-scale based on multi-source data characterizing land-use, geography and socio-economy. The geographic detector model is used to identify the driving forces associated with LUFs changes. Zhangjiakou City, a typical ecologically fragile area in North China, is selected as an empirical study area. The results show that during 1990–2015, land-use economic, social, and ecological functions greatly enhanced, especially the social function. Additionally, LUFs are spatially heterogeneous and clustered due to the terrain and socio-economic conditions. Among three LUFs, Land-use economic and social functions primarily display coordination. Land-use ecological and economic functions, as well as ecological and social functions, are coordinated in mountainous and hilly areas, while are conflicted in the Yang River valley. The driving mechanisms of multiple LUFs originate from spatially different coupling of natural conditions and anthropic activities, but economic development and social life are primarily responsible for LUFs changes. Policymakers are suggested to optimize ecological–living–production spaces by coordinating LUFs. Thus, this study can help mitigate LUFs conflicts and further improve the harmonization of ecological–living–production spaces.

摘要：
It is urgent and important to explore the regional differences and dynamic evolution of urban land green use efficiency (ULGUE) in the context of green development. The SBM-Undesirable model was used in this study alongside coefficient of variation and kernel density estimation to analyze the spatial-temporal pattern and dynamic evolution of ULGUE in 25 cities across the Yangtze River Delta, China from 2004 to 2015. Carbon emissions resulting from the urban construction land and happiness index were placed into the ULGUE evaluation index framework. In terms of regional differences, ULGUE in the Yangtze River Delta appears to have trended upward from 2004 to 2015. The undesired output indicators representing average ULGUE were 0.7131 and 0.7323, respectively, while the average values not including the undesired output indicators were 0.7612 and 0.8578. The Yangtze River Delta can be divided into advantaged, flat, and disadvantaged areas. Seven cities belong to the advantaged areas, fourteen cities to the flat areas, and four cities to the disadvantaged areas. The ULGUE of the whole and different types of urban areas in the Yangtze River Delta shows a highly skewed distribution and different degrees of polarization with time. Policy-wise, it is essential to completely consider the country?s resources and environmental conditions, especially in inter-city, urban, and rural-to build a beautiful China and to contribute meaningfully to the protection of the global eco-environment and food security.

摘要：
Land degradation has become one of the major global environmental problems threatening human well-being. Whether degraded land can be restored has a profound effect on the achievement of the 2030 UN Sustainable Development Goals. Therefore, the ways by which to identify the current research status and potential research topics in the massive scientific literature data in the field of land degradation is a crucial issue for scientific research institutions in various countries. In view of the shortcomings in the current research on the thematic evolution and thematic and thematic prediction, such as the ignorance of random features during scientific innovation, the defects of manual classification, and the difficulty of identifying technical terms, this research proposes a new combined method. First, the Latent Dirichlet Allocation (LDA) algorithm in machine learning is used to capture the potential clustering of themes in the literature sample set of land degradation research. The distribution characteristics and evolution of themes in each period are then analyzed. The method is combined with the Hidden Markov Model (HMM), which contains double stochastic process to quantitatively predict the trend of future thematic evolution. Finally, the above-mentioned combined method is used to analyze the evolution characteristics and future development trends of the themes in the field of land degradation. Comparative experiments show that the method in this study is effective and practical. The research results show that rangeland degradation, surface temperature, island, soil degradation, water quality, crop productivity and restoration are important research topics in the field of land degradation in the future. In addition, based on the advantages of this model, this model can be widely used in the thematic evolution and prediction analysis of different research fields in land use science.

摘要：
China's rural population ageing situation is extremely serious, and the social network has become a very important social and environmental factor to ensure the health. This study aims to explore the association mechanism between social network types and health-related behaviours among the elderly in rural Hubei Province, China. A cross-sectional cluster sample survey method was used to investigate elderly individuals aged 60 or older. The following three results were obtained: (1) the level of health-related behaviours differed significantly depending on their social network types. The rural elderly embedded in restricted and family restricted networks had lower levels of health-related behaviours than those in other networks, especially those in diverse networks; (2) Social network types were found to be significantly associated with health-related behaviours, the perceived quality of social relationships and social support and (3) Social network types not only had a direct effect on health-related behaviours (except for health-seeking behaviour), but also an indirect effect through the mediating effects of the perceived quality of social relationships and social support. Policy makers should formulate relevant measures to improve unfavourable social network types of the rural elderly, thus promoting their health.

摘要：
Cultivated land protection is the top priority of the national economy in China and the livelihood of people. Cultivated land protection policies (CLPP) play an important role in the protection of cultivated land. However, the process of dissemination of CLPP on social networks of farmers has problems, such as distortion of policy content, single dissemination channels, low level of farmers’ knowledge, and low dissemination efficiency. For revealing the characteristics of the dissemination of CLPP in the farmers’ social networks (FSN), this study combines the Suspected–Exposed–Infected–Recovered–Suspected (SEIRS) epidemic model to construct a model of CLPP dissemination suitable for FSN. In addition, a numerical simulation of the dissemination process of CLPP is conducted on the FSN, and the influence of the structural characteristics of the FSN and different model parameters on the dissemination of CLPP is analyzed. Results show that (1) the dissemination rate between farmers in FSN has a significant impact on the scale and speed of CLPP. A greater initial dissemination rate corresponds to faster speed and larger scale of CLPP dissemination. (2) A greater node degree in FSN means stronger dissemination ability for CLPP. Therefore, identifying structural holes (opinion leaders) in FSN can effectively promote the dissemination of CLPP. (3) The SEIRS model can dynamically describe the evolution law of CLPP dissemination process over time through the four states of farmer nodes of suspected, exposed, infected, and recovered. Numerical simulation results show that the immune degradation rate is proportional to CLPP. However, the direct immunization rate is inversely proportional. The increase in immune degradation rate can reduce the number of recovered farmers and improve the efficiency of CLPP dissemination. On the basis of the abovementioned conclusions, this study draws policy recommendations to increase the scale and speed of CLPP dissemination in China.
摘要：
China's long-standing urban-rural dichotomy has led to a widening gap between urban and rural areas, posing a huge challenge to the sustainable development of Chinese society. This paper adopted the subjective-objective weighting method, coupled coordination degree model, and geographically weighted regression model to conduct urban-rural sustainable development research on 31 provincial administrative regions in China and discussed their spatial-temporal divergence and driving mechanisms during 2007-2018. The results showed that (1) the quality of both rural revitalization and new urbanization improved during the study period, and the gap between them showed a trend of increasing after fluctuations. Both of them had significant spatial and temporal divergence characteristics. (2) The urban-rural coupling coordination degree in China continued to increase during the study period and showed an overall pattern of "high in the east-west and low in the north and southwest ". The changes of relative development type indicated that new urbanization had far surpassed rural revitalization during the study period. (3) The coefficients of driving factors varied significantly in space, showing a hierarchical band distribution. Seven of the eight driving factors showed a strong positive correlation in the vast majority of regions. The results and suggestions of this research can further promote the organic combination of rural revitalization and new urbanization strategy, which is of great practical significance for narrowing the urban-rural gap and realizing sustainable urban-rural development. Likewise, it can be a reference for other developing countries around the world.</p>

size of land finance;reliance on land finance;regional integration;urban agglomerations in the middle reaches of the Yangtze River;China
摘要：
Exploring the relationship between land finance and regional integration is of great significance for optimizing the land management system and promoting high-quality development. Previous studies focused on the impact of land finance on regional development, and rarely concerned the role of regional integration on land revenue. This study reveals the internal association mechanisms between land finance and regional integration, which might provide an integrated theoretical and empirical support for the coordinated development between urban land market and regional economy. We firstly provide a theoretically analytical framework for the relationship between the size of land finance, reliance on land finance, and regional integration, and three hypotheses are proposed. On this basis, an econometric analysis is conducted based on the panel data of the urban agglomerations in the middle reaches of the Yangtze River (UAMRYR) from 2003 to 2016. The results show that an increased amount of land finance revenue promotes the level of regional integration. Specifically, for every 1% increase in the size of land finance of UAMRYR, Wuhan city-clusters, and Chang-Zhu-Tan city-clusters, the level of regional integration will increase by 0.000040%, 0.000021%, and 0.000089%, respectively. Besides, the degree of land finance dependence has a negative impact on the level of regional integration. The threshold regression analysis indicates an inverted U-shaped curve could reflect the relationship between the level of regional integration and the degree of land financial dependence. This study argues that the governments in a particular urban agglomeration should clarify the net effect of the size of land finance and their reliance on land finance, and rationally introducing development strategy according to the synergy between land finance and regional integration.

high-speed rail;urban land use efficiency;propensity score matching-differences in differences;regional heterogeneity;China
摘要：
The construction and operation of high-speed rail (HSR) has become an important policy for China to achieve efficiency and fairness and promote high-quality economic growth. HSR promotes the flow of production factors such as labor and capital and affects economic growth, and may further affect urban land use efficiency (ULUE). To explore the impact of HSR on ULUE, this paper uses panel data of 284 cities in China from 2005 to 2018, and constructs Propensity Score Matching-Differences in Differences model to evaluate the effect of HSR on ULUE. The result of entire China demonstrates that the HSR could significantly improves the ULUE. Meanwhile, this paper also considers the heterogeneity of results caused by geographic location, urban levels and scales. It demonstrates that the HSR has a significantly positive effect on ULUE of Eastern, Central China, and large-sized cities. However, in Western China, in medium-sized, and small-sized cities, the impact of HSR on ULUE is not significant. This paper concludes that construction and operation of HSR should be linked to urban development planning and land use planning. Meanwhile, the cities with different geographical locations and scales should take advantage of HSR to improve ULUE and promote urban coordinated development.

摘要：
Severe land shortage causes a higher demand for domestic and foreign land-intensive products. As a result, resource utilization, and related environmental issues, will increase in urban areas. To this respect, the analysis of the impact of environmental regulation on urban land use efficiency helps to identify potential points for interventions designed to ensure sustainable land use. This study first introduces a theoretical framework to investigate the micro-transmission mechanism of environmental regulation on urban land use efficiency. Our profit decision-making model concludes that the impact of environmental regulation on urban land use efficiency is influenced by changes in the industrial structure. Empirically, our preliminary analysis suggests that in addition to population density, both formal and informal environmental regulation can promote urban land use efficiency, with a significant spatial heterogeneity across the sample regions. Further, this study shows a remarkable double-threshold relationship between formal environmental regulation and urban land use efficiency in China. We clarify and confirm that environmental regulation promoted urban land use efficiency only when regulation intensity was higher than 0.8612. Environmental regulation increased urban land use efficiency in high-level industrial rationalization areas, whereas it had the opposite effect in low-level ones. Furthermore, there was a clear marginal diminishing effect of the impact of environmental regulation on urban land use efficiency when the optimization of the industrial structure was set as a threshold variable.
