A wealth distribution model with a non-Maxwellian collision kernel

A non-Maxwellian collision kernel is employed to study the evolution of wealth distribution in a multi-agent *** collision kernel divides agents into two different groups under certain conditions. Applying the kinetic theory of rarefied gases, we construct a two-group kinetic model for the evolution of wealth distribution. Under the continuous trading limit, the Fokker–Planck equation is derived and its steady-state solution is obtained. For the non-Maxwellian collision kernel, we find a suitable redistribution operator to match the taxation. Our results illustrate that taxation and redistribution have the property to change the Pareto index.

新时代文化强国战略为我国文化产业发展指明了方向,确立了目标,少儿出版业应努力为文化强国建设添砖加瓦。然而近年来少儿出版领域出现了“问题童书”现象。借用媒介信息四维度理论,从认知维度、情感维度、美学维度及道德维度对这些“问题童书”进行了归类,分析了出现“问题童书”的主要原因:管理条例中相关规定较为模糊;编审人员知识结构不够完备;出版审查制度执行不够严格;有效反馈和评价机制尚未建立。为防范“问题童书”,提升少儿出版物内容质量,探讨了如下有效对策:制定细化的内容分级及审查标准;提升编审人员的实践与理论水平;执行严格的图书审校制度;建立紧密的公共图书馆反馈机制;充分发挥的行业协会监督职能;成立权威的阅读指导公益组织。

统筹经济韧性与生态效率间的动态平衡关系是实现区域可持续发展的重要抓手。以中国30个省份为研究对象,采用组合权重模型、全局非期望超效率SBM模型分别测度国内省级区域适应性循环理论与驱动-压力-状态-响应(DPSR)模型分析框架下的经济韧性、投入产出理论下的生态效率,并通过改进的哈肯模型刻画经济韧性与生态效率间的协同演化特征。结果表明:(1)经济韧性能力在样本观测期内显著上升,区域差异明显扩张,南北区域发展不平衡,存在一定的“东-中-东北-西”阶梯效应。(2)生态效率水平总体呈下降的趋势,区域差异历经“扩张-缩小-再扩张”变化,存在显著性阶梯失衡现象,空间呈“沿海-内陆”递减分布。(3)经济韧性与生态效率的协同演化历经稳定、下降及稳定三阶段,区域间基本不存在阶梯性失衡现象,经济韧性作为协同演化的序参量,主导区域可持续发展。

高新技术企业已成为区域创新活动的重要载体,具有空间集聚特征。文章利用空间自相关、核密度分析、标准差椭圆和MGWR模型等方法对2000—2023年北京高新技术企业分布特征、演变格局及影响因素进行了分析与探讨。结果表明:①北京高新技术企业空间自相关性先增强后减弱,整体空间格局变化较小且趋向稳定发展;不同类型企业呈现出明显的集聚特征,并都有其特定的高密度集聚区域。②MGWR模型可以在不同的空间尺度上调整权重,更精细地揭示高新技术企业在不同尺度上的异质性。③不同因素对高新技术企业分布作用强度不同且在空间上具有异质性,MGWR模型全局影响因素回归结果与分类型结果存在显著差异。研究成果可为政府和企业制定科学合理的产业规划和创新政策提供科学依据。
