Population ageing in healthcare – a minor issue? Evidence from Switzerland

Our study shows that population ageing is a relevant determinant of healthcare expenditure (HCE). This conclusion supports the popular, but recently strongly contested, view that the coming population ageing will threaten the fiscal sustainability of health systems. We contribute to this debate, first by estimating the determinants of Swiss HCE with outlier-robust dynamic regressions, and second, by projecting Swiss HCE based on the estimates produced and new population scenarios. Medical advances and GDP per capita also play a decisive role. Governments can mitigate HCE growth by improving the health status of the population and by stimulating cost-effective and productive medical advances.     

城镇化背景下治安治理社会化的探索与创新——以钱江世纪城派出所“物业联席会”创建为例

治安治理社会化的核心是社会力量的参与。从宋代的民治传统到建国以来的政策与实践探索,从警务社会化、治安管理社会化到治安社会化、社会治安社会化治理等概念的相继提出,构成了治安治理社会化的演进脉络。治安治理社会化的本质是治安秩序维护的多元化,强调多元化共治、过程性理念与互动性思维的有机统一。杭州市公安局萧山区分局以“物业联席会”机制创建为载体,整合社会资源,激发社会组织活力,为治安治理社会化提供了更多可能的路径。借鉴“物业联席会”的创建经验,城镇化背景下的治安治理社会化应坚持党委组织领导,协同推进组织载体创新、联动机制创新与智慧化手段运用相融合。     

Migration decisions under ambiguity: Migration distance effects revisited

There is ample evidence that distance has a strong negative effect on migration. Despite its significance in migration decisions, scholars rarely explore the migration distance effect deeper than the first level of interpretation derived from the simple neoclassical theory of migration. This study revisits the migration distance effect in the spirit of Knightian distinction between risk and uncertainty. To this end, this study attempts to construct estimates of the risk premium migrants are willing to pay to avoid the risk associated with migration distance. The results show that the magnitude of the distance effect is not rationalized by risk aversion in the Arrow–Pratt sense (Arrow, 1965, The theory of risk aversion, Yrjo Jahnssonin Saatio, Helsinki, Finland, 90; Pratt, 1964, Econometrica, 32, 122). In particular, the risk premium demanded by distant rural residents is unjustifiably higher compared with that of those living closer to urban areas in their migration decisions. The results suggest that the migration distance effect is analogous to the equity home bias puzzle and the Ellsberg paradox in that the assumption of subjective expected utility can lead to seemingly irrational human behaviors. Some of the findings in this study shed light on the role of subjective aspects such as perception, confidence, and pessimism in migration decisions, which have been neglected in the literature.     

黄河经济带上游区域低碳经济发展现状与发展战略分析

黄河经济带上游区域作为"一带一路"的"源头",向西关系到丝绸之路经济带的崛起和我国向西开放的进程;向东延伸与我国沿海经济带相连,起到承上启下的作用。文章选取黄河经济带上游区域为研究对象,首先基于脱钩理论研究碳排放与经济增长脱钩关系;其次从人均生产总值、能源消费量、碳排放、城市化水平和服务化水平五个指标出发,分析经济增长影响碳排放的路径。研究发现:全国和黄河经济带上游区域脱钩拟合曲线趋势先向上、后向下,但黄河经济带上游区域脱钩指标值开始下降的时间晚、速度慢,说明其低碳经济发展程度落后于全国水平。经济增长通过两条路径影响碳排放:经济增长通过提高城市化水平对碳排放具有促进效应,通过提高服务化水平对碳排放形成减弱效应。     

中国城镇化包容性发展中的公共投资支持影响研究

本文通过构建城镇化包容性发展指标体系，测度出中国2003—2015年30个省级区域的城镇化包容性发展指数，经莫兰指数检验发现其具有显著的空间正相关性。进而采用空间计量模型，基于户籍制度改革背景，从生产性公共投资、社会性公共投资与环保性公共投资三个方面研究公共投资对城镇化包容性发展的影响。研究结果表明，生产性公共投资与社会性公共投资对城镇化包容性发展均存在显著的正向支持作用，且户籍制度改革变量与二者产生了正向的交互作用，说明随着对人口流动限制的放松，生产性公共投资与社会性公共投资对城镇化包容性发展的支持作用有所增强，但环保性公共投资未能表现出显著的支持作用。在未来城镇化进程中，应当优化调整中国公共投资的行业结构与区域结构，从而更好地提升城镇化包容性发展水平。     

英国城乡规划体系及农村规划管理的经验与启示

[目的]对英国城乡规划体系及农村规划管理的发展历程、基本经验和主要特点进行归纳总结,分析其对我国当前加强农业与农村规划管理、推进城乡统筹发展、促进新型城镇化建设的启示和借鉴意义。[方法]基于赴英国进行城乡规划体系及农村规划管理与保护方面的实地考察、培训以及相关文献的综述分析。[结果]英国城乡规划体系建立缘于其解决城镇化发展过程所产生的"大城市病"问题,其发展经历了多次修改和调整,目前形成了"区域空间战略"和"地方发展框架"两级规划结构;英国的城乡规划体系十分注重对农村地区和小城镇的规划管理和保护,形成了一系列重要规则和制度。[结论]英国在城镇化发展过程中,完整地保存了传统乡村的历史建筑、风土文化和景观环境,值得充分学习和借鉴。当前,在统筹城乡发展和推进新型城镇化建设过程中,应充分发挥规划的引导作用和社会公众的参与作用,高度重视对农业与农村的保护和规划管理,同时要注重基于中国国情的再创新。     

Cacao Capitalism and Extended Urbanization: On the Contradictory Origins of Bounded Urbanism in Nineteenth‐century Coastal Ecuador

This article challenges both contemporary and classic urban theory by analyzing the historical case of coastal Ecuador. Working from primary and secondary sources, I track the urbanization of coastal Ecuador during the long nineteenth century, when cacao exports determined not only the economic wellbeing of the city of Guayaquil, but of the entire tropical lowland region. I argue that this extended urban geography was both experienced and practiced as an unbounded economic and cultural region. As the value of cacao exports skyrocketed, capitalists in the city invested in infrastructural projects and financial instruments, divorcing money‐making from cacao production. After the Gran Incendio (great fire) of 1896, the city was rebuilt according to the ideals of modern liberal planning that further separated the city from the country symbolically, despite their continued material interconnection. This work suggests that long histories of capitalist urbanization provide material and theoretical support for critiquing bounded urban theory both past and present, by moving beyond the city and highlighting the processes undergirding spatial production under capitalist social relations. Likewise, this historical case study argues that city‐centrism, rather than being constituted epistemologically, was tied to liberal notions of the urban based on nineteenth‐century ideologies of modernization and progress.     

老龄化与碳排放：消费效应还是生产效应？——基于2002-2017年中国省级面板数据的实证研究

人口老龄化是经济增长的一大阻碍,它对碳排放的影响是做出环境政策抉择的关键因素.以中国2002—2017年的省级面板数据为研究样本,从理论与实证两个层面分析人口老龄化与碳排放的关系及影响机制.一方面,构建包含碳排放的世代交叠模型(overlapping generations,OLG),发现老龄化主要通过消费效应和生产效应两个路径对碳排放产生影响;另一方面,从实证层面发现老龄化与碳排放之间存在倒"U"形关系,而且消费效应在人口老龄化与碳排放的关系中起到部分中介作用,生产效应的影响则不显著.     

南京江北新区新型城镇化发展质量评价与提升路径

文章构建了由31项指标组成的新型城镇化综合发展质量评价指标体系,运用AHP层次分析法和熵值法,选择19个国家级新区中2018年经济总量排名前十的新区进行定量对比分析,并结合民生幸福建设群众满意度问卷调查分析,对南京江北新区新型城镇化发展质量进行综合评价。研究表明:(1)南京江北新区新型城镇化整体发展处于中上游水平,与发达新区相比存在一定差距,产业结构亟需优化;(2)发展增长方式、资源利用率、环境保护类指标明显落后;(3)科教文卫、居民生活等指标具有比较优势。文章最后提出新型城镇化提升路径为加快生态环境和公共服务建设,积极提升科教和生态示范效应,做大做强主导产业,促进城乡特色均衡发展和推进以人为核心的新型城镇化。     

西部地区新型城镇化和乡村振兴互动关系研究

新型城镇化和乡村振兴是解决城乡发展面临困境的重要战略,明确两大战略的发展现状及其互动关系,对西部地区实现资源的有效配置、促进城乡融合有重要意义。基于我国西部地区12个省份2013—2018年的面板数据,建立了西部地区新型城镇化和乡村振兴的评价指标体系,运用熵值法和耦合协调度模型测算出西部地区两大战略的发展水平及其耦合协调度。结果发现,2013—2018年,西部地区的新型城镇化水平不断提高,乡村振兴的发展水平低于新型城镇化水平;两大战略发展存在空间差异,且发展水平高的地区其耦合协调度也较高,在内蒙古、重庆、广西和四川等发展水平较高的地区,两大战略实现良性互动,在青海和西藏等比较落后的地区,两者勉强协调。西部地区需要加强农村的基础设施建设,注重交通通信的发展,重视人力资源,加强生态环境建设,加快产业结构的优化升级,实现两大战略的高水平协调共振和城乡融合发展。
