How can technology and efficiency alleviate the dilemma of economic growth and carbon emissions in China's industrial economy? A metafrontier decoupling decomposition analysis

This paper attempts to explore the decoupling relationship and its drivers between industrial economic increase and energy-related CO_(2) emissions(ICE). Firstly, the decoupling relationship was evaluated by Tapio index. Then, based on the DEA meta-frontier theory framework which taking into account the regional and industrial heterogeneity and index decomposition method, the driving factors of decoupling process were explored mainly from the view of technology and efficiency. The results show that during2000-2019, weak decoupling was the primary state. Investment scale expansion was the largest reason hindering decoupling process of industrial increase from ICE. Both energy saving and production technology achieved significant progress, which facilitated the decoupling process. Simultaneously, the energy technology gap and production technology gap among regions have been narrowed, and played a role in promoting decoupling process. On the contrary, both scale economy efficiency and pure technical efficiency have inhibiting effects on decoupling process. The former indicates that the scale economy of China's industry was not conducive to improve energy efficiency and production efficiency, while the latter indicates that resource misallocation problem may exist in both energy market and product market.

Multi-scenario Simulation and Spatial-temporal Analysis of LUCC in China's Coastal Zone Based on Coupled SD-FLUS Model

Increased human activities in China's coastal zone have resulted in the depletion of ecological land resources.Thus,conducting current and future multi-scenario simulation research on land use and land cover change(LUCC)is crucial for guiding the healthy and sustainable development of coastal zones.System dynamic(SD)-future land use simulation(FLUS)model,a coupled simulation model,was developed to analyze land use dynamics in China's coastal zone.This model encompasses five scenarios,namely,SSP1-RCP2.6(A),SSP2-RCP4.5(B),SSP3-RCP4.5(C),SSP4-RCP4.5(D),and SSP5-RCP8.5(E).The SD model simulates land use demand on an annual basis up to the year 2100.Subsequently,the FLUS model determines the spatial distribution of land use for the near term(2035),medium term(2050),and long term(2100).Results reveal a slowing trend in land use changes in China's coastal zone from 2000–2020.Among these changes,the expansion rate of construction land was the highest and exhibited an annual decrease.By 2100,land use predictions exhibit high accuracy,and notable differences are observed in trends across scenarios.In summary,the expansion of production,living,and ecological spaces toward the sea remains prominent.Scenario A emphasizes reduced land resource dependence,benefiting ecological land protection.Scenario B witnesses an intensified expansion of artificial wetlands.Scenario C sees substantial land needs for living and production,while Scenario D shows coastal forest and grassland shrinkage.Lastly,in Scenario E,the conflict between humans and land intensifies.This study presents pertinent recommendations for the future development,utilization,and management of coastal areas in China.The research contributes valuable scientific support for informed,long-term strategic decision making within coastal regions.

Cenozoic giant coal-bearing basin belt discovered in China's sea and its adjacent areas

Sea area is an important area of oil and gas exploration in China.It has been found that China's sea area mainly consists of coal type oil and gas,and the exploration of coal-bearing series source rocks has become an important part of oil and gas exploration there.Through years of comprehensive geological research in China's sea area,it has been revealed that it has undergone multiple occurrences of tectonic opening and closing movements in varying degrees in the Paleogene,forming 26 Cenozoic sedimentary basins of various types,such as active continental margin,passive continental margin,transitional continental margin and drift rift basins.In the present study,it is observed for the first time that coal type source rocks are mainly developed in 14 continental margin basins in China's sea area,revealing that a very large C-shaped coal-bearing basin group developed there in the Cenozoic.Next,based on the coupling analysis of paleoclimate,paleobotany,paleogeography and paleostructure,it is observed that there are five coal-forming periods in China's sea area,namely the Paleocene,Eocene,early Oligocene,late Oligocene and Miocene-Pliocene,and the coal-forming age is gradually new from north to south.It is also found that the coal seams in the sea area are mainly developed in three coal-forming environments in Cenozoic,namely delta,fan delta and tidal flat-lagoon.The coal seams developed in different environments are characterized by thin thickness,many layers and poor stability.However,the coal-bearing series source rocks in China's sea area have a wide distribution range,very high thickness and large amount,thus forming a material basis for the formation of rich coal type oil and gas.

权力结构视阈下的两岸区域治理机制互动

1986年至今两岸区域治理机制互动呈现出四个阶段的不同特点:“大陆一体化统一偏向Vs.台湾吸收统一偏向”时期的单维开启、“大陆一体化统一偏向Vs.台湾独立偏向”时期的多类并行、“大陆一体化统一偏向Vs.台湾不统不独偏向”时期的稳步延展、“大陆一体化统一偏向Vs.台湾独立偏向”时期的现状维持。以“权力结构”为理论视阈,从国家硬权力结构、国家软权力结构、国际硬权力结构、国际软权力结构分析可见,开启与加速两岸区域治理机制互动的权力结构为:国家硬权力结构、国家软权力结构、国际软权力结构三者的和平统一偏向。维系与稳定两岸区域治理机制互动的权力结构为:国家软权力结构与国际软权力结构二者的和平统一偏向。不显著影响两岸区域治理机制互动的权力结构为:国际硬权力结构未有显示统一偏向。由此可证“权力结构影响两岸区域治理机制互动”的假设。就影响力而言,国家权力结构大于国际权力结构,其中,国家硬权力结构是关键前提,国家软权力结构是重要基础。因此,两岸区域治理机制友好互动,需要继续稳定国家软权力结构与国际软权力结构的和平统一偏向,需要推进国家硬权力结构从武力统一偏向转为和平统一偏向,进而促进中国台湾海峡两岸融合发展与中国国家和平统一进程。

“一国两制”台湾方案研究:现状、评价与深化方向

习近平总书记在《告台湾同胞书》发表40周年纪念会上发表重要讲话之后,学界围绕“‘一国两制’台湾方案”展开了深入研究。从既有成果看,学界研究主要聚焦在“‘一国两制’台湾方案”的政策脉络、价值意义、制度架构、实现路径、比较借鉴等议题,并取得了丰硕的理论成果。这些成果形成了“一国两制”台湾方案的基本框架、丰富了“一国两制”台湾方案的内容、拓宽了相关研究的视野,但同时也存在创新性不足、研究议题和内容分布不平衡、比较政治视野下的研究较为稀缺、研究议题不聚焦等问题。今后应加强对中央与中国台湾地区共治、支撑制度的落实机制、对台湾同胞意见和建议的吸纳、对台湾地区当局目前所控海域的未来管辖,以及对“一国两制”港澳实践经验的深度挖掘等问题的研究,进一步提高“一国两制”台湾方案的可行性。

Enhanced Cooling Efficiency of Urban Trees on Hotter Summer Days in 70 Cities of China

Increasing the urban tree cover percentage(TCP) is widely recognized as an efficient way to mitigate the urban heat island effect. The cooling efficiency of urban trees can be either enhanced or attenuated on hotter days, depending on the physiological response of urban trees to rising ambient temperature. However, the response of urban trees' cooling efficiency to rising urban temperature remains poorly quantified for China's cities. In this study, we quantify the response of urban trees' cooling efficiency to rising urban temperature at noontime [~1330 LT(local time), LT=UTC+8] in 17summers(June, July, and August) from 2003–19 in 70 economically developed cities of China based on satellite observations. The results show that urban trees have stronger cooling efficiency with increasing temperature, suggesting additional cooling benefits provided by urban trees on hotter days. The enhanced cooling efficiency values of urban trees range from 0.002 to 0.055℃ %-1 per 1℃ increase in temperature across the selected cities, with larger values for the lowTCP-level cities. The response is also regulated by background temperature and precipitation, as the additional cooling benefit tends to be larger in warmer and wetter cities at the same TCP level. The positive response of urban trees' cooling efficiency to rising urban temperature is explained mainly by the stronger evapotranspiration of urban trees on hotter days.These results have important implications for alleviating urban heat risk by utilizing urban trees, particularly considering that extreme hot days are becoming more frequent in cities under global warming.

Surveillance of Hand,Foot,and Mouth Disease in China's Mainland (2008-2009)

Objective Since HFMD was designated as a class C communicable disease in May 2008,18 months surveillance data have been accumulated to December 2009.This article was to describe the distribution of HFMD for age,sex,area,and time between 2008 and 2009,to reveal the characteristics of the epidemic.Methods We analyzed weekly reported cases of HFMD from May 2008 to December 2009,and presented data on the distribution of age,sex,area and time.A discrete Poisson model was used to detect spatial-temporal clusters of HFMD.Results More than 1 065 000 cases of HFMD were reported in China's Mainland from May 2008 to December 2009 （total incidence：12.47 per 10 000）.Male incidence was higher than female for all ages and 91.9% of patients were 5 years old.The incidence was highest in Beijing,Shanghai,Zhejiang and Hainan.The highest peak of HFMD cases was in April and the number of cases remained high from April to August.The spatial-temporal distribution detected four clusters.Conclusion Children 5 years old were susceptible to HFMD and we should be aware of their vulnerability.The incidence was higher in urban than rural areas,and an annual pandemic usually starts in April.

Hyperthermic intraperitoneal chemotherapy for gastric and colorectal cancer in China's Mainland

AIM:To investigate the current status of peritoneal carcinomatosis(PC) management,as well as the usage of cytoreductive surgery(CRS) and hyperthermic intraperitoneal chemotherapy(HIPEC) in China's Mainland.METHODS:A potentially curative therapeutic strategy for selecting patients with PC,known as "Techniques",consists of CRS in combination with HIPEC.A systemic search of published works and clinical trials was performed.Additional papers were retrieved by crosschecking references and obtaining information from Chinese oncologists and relevant conferences.One hundred and one papers and one registered clinical trial on HIPEC were included.RESULTS:A literature review identified 86 hospitals in 25 out of all 31 areas of China's Mainland that perform HIPEC.The earliest report included in our survey was published in 1993.Different approaches to HIPEC have been utilized,i.e.palliative,prophylactic,and possiblycurative treatment.Only one center has consistently performed HIPEC according to the "Sugarbaker Protocol",which involves evaluating the extent of PC with peritoneal cancer index and the results of CRS with the completeness of cytoreduction.Positive preliminary results were reported:7 of 21 patients with PC survived,free of tumors,during an 8-43-mo follow-up period.Hyperthermic strategies that include HIPEC have been practiced for a long time in China's Mainland,whereas the "Sugarbaker Protocol/Techniques" has been only rarely implemented in China.The Peritoneal Surface Oncology Group International hosts a biannual workshop with the intent to train more specialists in this field and provide support for the construction of quality treatment centers,especially in developing countries like China,whose population is huge and has a dramatically increased incidence of cancer.CONCLUSION:To popularize Sugarbaker Protocol/Techniques in China's Mainland in PC management arising from gastric cancer or colorectal cancer will be the responsibility of the upcoming Chinese Peritoneal Surface Oncology Group.

Modeling the impacts of climate change on China's agriculture

The impacts of climate change on China's agriculture are measured based on Ricardian model. By using county-level cross-sectional data on agricultural net revenue, climate, and other economic and geographical data for 1275 agriculture-dominated counties in the period of 1985-1991, we find that both higher temperature and more precipitation will have overall positive impact on China's agriculture. However, the impacts vary seasonally and regionally. Higher temperature in all seasons except spring increases agricultural net revenue while more precipitation is beneficial in winter but is harmful in summer. Applying the model to five climate scenarios in the 2020s and 2050s shows that the North, the Northeast, the Northwest, and the Qinghai-Tibet Plateau would always benefit from climate change while the South and the Southwest may be negatively affected. For the East and the Central China, most scenarios show that they may benefit from climate change. In conclusion, climate change would be beneficial to the whole China.
