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.

Object Tracking Algorithm Based on Multi-Time-Space Perception and Instance-Specific Proposals

Aiming at the problem that a single correlation filter model is sensitive to complex scenes such as background interference and occlusion,a tracking algorithm based on multi-time-space perception and instance-specific proposals is proposed to optimize the mathematical model of the correlation filter(CF).Firstly,according to the consistency of the changes between the object frames and the filter frames,the mask matrix is introduced into the objective function of the filter,so as to extract the spatio-temporal information of the object with background awareness.Secondly,the object function of multi-feature fusion is constructed for the object location,which is optimized by the Lagrange method and solved by closed iteration.In the process of filter optimization,the constraints term of time-space perception is designed to enhance the learning ability of the CF to optimize the final track-ing results.Finally,when the tracking results fluctuate,the boundary suppres-sion factor is introduced into the instance-specific proposals to reduce the risk of model drift effectively.The accuracy and success rate of the proposed algorithm are verified by simulation analysis on two popular benchmarks,the object tracking benchmark 2015(OTB2015)and the temple color 128(TC-128).Extensive experimental results illustrate that the optimized appearance model of the proposed algorithm is effective.The distance precision rate and overlap success rate of the proposed algorithm are 0.756 and 0.656 on the OTB2015 benchmark,which are better than the results of other competing algorithms.The results of this study can solve the problem of real-time object tracking in the real traffic environment and provide a specific reference for the detection of traffic abnormalities.

《公司法》修改中治理制度的创新、不足及完善

组织设置不合理、权责配置失当、股东行权保障不足、信义义务内容过于抽象是引发我国公司治理实践出现诸多问题的症结所在。在《公司法》修改中,三份草案和修订案都赋予章程设定除股东会及董事会之外的其他公司组织的自主权。新法通过降低股东临时提案权行使门槛、优化知情权行使规则、细化信义义务内容等方式力保股东权行使顺畅。但优化后的公司治理制度仍然存在不足:审计委员会的职能内容、人员构成及保障独立性的手段不合理或缺失,股东提案审查、持股期限要求及救济途径不够具体,针对董事和控股股东的责任规则亟待完善。立法应明确审计委员会的监督职能,区分其与监事会的责权界限;规定股东会召集人作为提案审查主体,增设事前救济机制作为股东行权保障;确认控股股东在公司治理中的实质地位,并实行职权代行制度;还应通过立法强化控股股东的行权规范。

大学公共俄语教学现状与教学改进建议

近几年,随着选择俄语作为高考外语考试科目的考生人数上升,进入大学后选修俄语为公共外语的学生也逐年增多。然而,在教学过程中我们发现,大部分俄语新生的词汇量、阅读与翻译能力、言语交际能力尚达不到大学俄语教学指南和大纲的基本入学要求。德州学院对全国35所高校的公共俄语教学情况进行了为期两年的跟踪调研,针对当前高校俄语生源成绩呈橄榄形分布的特点和学生需求,提出了适当增加公共俄语课时,优化师资配置,艺体生、文科生、理科生分班教学,更新细化教材内容,多校联合教学教研,为学生提供口语实践机会等建议,以提升大学公共俄语整体教学水平,为国家输送既懂专业又精通俄语的合格人才。

以创造精神抓住契机推动世界贸易组织上诉机制的改革

习近平总书记在2023年9月27日中共中央政治局有关世界贸易组织规则与世界贸易组织改革的集体学习会上强调,“参与世界贸易组织改革,要坚定维护以世界贸易组织为核心的多边贸易体制权威性和有效性,积极推动恢复世界贸易组织争端解决机制正常运转”。在WTO上诉机制已经陷入危机、多边贸易体制本身相关性受损的背景下,启动恢复上诉机制的谈判,应是推动WTO改革的优先事项和中国的选项。近年来,美国企图利用其他成员恢复上诉机制的动机以引入针对“非市场导向的政策和做法”的规则。拜登政府近期的动作表明美国前述意图已经有所松动。在各界提出的上诉机制改革新方案中,“沃克原则”和“伍尔夫建议”因应美国诉求以推动美国支持上诉机制改革,具有可行性。包括中国在内的WTO成员方应抓住此契机,了解并梳理美国关于上诉机制的诉求,逐项考虑其可接受性,以此推动上诉机制的改革。

人类命运共同体:构建更加公正合理国际秩序的中国方案

人类命运共同体是新时代构建更加公正合理国际秩序的中国方案。而“美国优先”则是根源于美国实用主义哲学,以“美国第一”为标准,为实现其霸权服务的美国对外政策。人类命运共同体与“美国优先”在目标、原则、实现路径等方面存在根本区别。人类命运共同体自提出以来,由理念到理论,由愿景到现实,由双边到多边,已成为引领时代潮流和人类前进方向的鲜明旗帜。“美国优先”与世界发展大势背道而驰,破坏现行国际秩序和国际体系,必然不可持续。
