Enhancing the comprehensive development resilience of urban agglomerations is crucial for strengthening regional risk resistance and promoting high-quality coordinated development of the region.This study focused on the Beijing-Tianjin-Hebei urban agglomeration,utilizing the entropy weight TOPSIS method to systematically evaluate the comprehensive development resilience,economy resilience,society resilience,eco-system resilience,infrastructure resilience,and urban governance resilience of the urban agglomeration.Additionally,an obstacle degree model was employed to identify and analyze the obstacles affecting the urban development resilience of the Beijing-Tianjin-Hebei urban agglomeration from 2010 to 2022.The results indicate that:The comprehensive resilience of the Beijing-Tianjin-Hebei urban agglomeration exhibits a fluctuating upward trend during the study period,but remains at a relatively low level,economic resiliencehas begun to decline to a lower level since 2014,and urban governance resilience has continued to rise;Although there are significant variations of the comprehensive resilience among cities,they all demonstrate an upward trend;Certain differences exist among the cities and their resilience subsystems,with Beijing and Tianjin ranking ahead in economy resilience,infrastructure resilience and governance resilience,economy resilience has emerged as the primary restrictive resilience subsystem of this urban agglomeration,and the eco-system resilience constantly hampers its comprehensive development resilience;The main obstacle factors of all the cities include loan-to-deposit ratio,emergency knowledge promotion,actual utilization of foreign investment,annual passenger volume,and comprehensive emergency command center.Based on these findings,corresponding suggestions have been proposed in order to provide reference for promoting the resilience of Beijing-Tianjin-Hebei urban agglomeration development.
在区域重大发展战略和区域协调发展战略的背景下,考察重大国家战略区域新一代信息技术产业绿色创新效率的态势及其空间差异,对于全面协同提升我国新一代信息技术产业绿色创新效率具有重要意义.运用超效率EBM模型综合测度了2011-2020年重大国家战略区域新一代信息技术产业的绿色创新效率,并借助Dagum基尼系数及其分解方法全面考察绿色创新效率的区域差异及其来源.研究发现,样本考察期内各省份新一代信息技术产业绿色创新效率水平呈明显的上升态势,"十三五"期间,多数地区新一代信息技术产业的绿色创新效率相比"十二五"期间均有所提升;重大国家战略区域新一代信息技术产业绿色创新效率的空间差异呈下降趋势,总体差异主要来源于区域间差异.
以2007-2020年中国108家商业银行的非平衡面板数据为样本,探讨经济政策不确定性对商业银行信贷供给规模和结构两方面的影响,并建立了3个间接作用机制.实证研究结果显示:经济政策不确定性加大会显著抑制商业银行的信贷供给规模,且大型国有商业银行更为敏感;随着经济政策不确定性的加大,商业银行会改变其信贷供给结构,将信贷投向风险较小的个人贷款、信用贷款和中长期贷款;信贷资金来源方的储蓄意愿、信贷需求方的贷款需求,在经济政策不确定性影响商业银行信贷供给的过程中,承担着部分中介作用,而货币政策渠道具有一定的遮掩效应.
建设世界一流科技期刊已成为我国科技期刊界的重要目标和紧迫任务.一流的编辑人才是打造一流期刊的基础和关键,编辑力的构成要素是编辑人才队伍建设的依据.在建设世界一流科技期刊背景下,科技期刊编辑除了具备传统的职业能力外,还需具备科研力、成果引导力、高效执行力、媒体融合力和服务力,这些能力是编辑力的核心,也是提高我国科技期刊的学术质量、影响力和国际竞争力,推动科技期刊走向世界一流的根本保障.
"南皮落子"具有"文武兼备"的舞蹈风格、地方特色歌曲和伴奏、丰富的表演形式等特点,是传统舞蹈类国家级非物质文化遗产的典型代表.通过研究文献和馆藏南皮地方资料,梳理了"南皮落子"的发展历史和艺术价值,分析了以政府主导的非物质文化遗产保护机制实施状况及面临的多元文化冲击、传承人年龄老化和新曲目编创缺乏等问题.从主动融入国家地区发展战略和寻求多传播途径等方面,提出完善数字化资源、健全地方非物质文化遗产保护制度、加强传承体验设施建设、打造非物质文化遗产旅游产业、开设非物质文化遗产课程等具体举措,为新时期"南皮落子"的保护与发展提供参考.
