市场开放进程中的工业企业集聚与人口城市化——长三角地区人口城市化的动因探析(1984—2002)

在渐进的市场改革和开放进程中,长三角地区以城市人口不断增加为表现的人口城市化进程并没有遵循城市化进程的国际经验,即城市化主要来自工业化的推动,而主要由于工业企业集中、政府干预和市场促进等多种因素的相互作用,人口城市化发展的演进特征则是上述诸多因素共同作用的结果。确切地说,不断增加的工业生产活动并没有对长江三角洲地区的城市化进程发挥明显作用,特别是在城市化加速发展阶段,市场开放进程中不断向市区集聚的工业企业的集聚行为(而非工业化)在很大程度上促进了城市化的快速发展。考察和分析了不同阶段长三角人口城市化发展的不同特征和区域差异。     

嘉兴市人口发展特征及对策

一个地区人口的发展状况是影响该地区社会，经济可持续发展的主要因素之一，该文根据人口普查材料，分析了嘉兴市的人口发展特征及趋势，并与浙江省内的其他城市的人口发展做了横向比较，从中归纳出嘉兴哪展特征对经济发展的制约因素，指出：重视人口素质的提高，加强城镇化建设及应对老龄化问题等是今后嘉兴市在人口发展过程中所需解决的主要问题。     

陕西构建和谐社会须切实控制出生人口性别比

出生人口性别比保持在正常值域是和谐社会的一个重要基础。陕西出生人口性别比显著高于正常值，且有加剧趋势。将对构建和谐社会带来严重后果，必须采取多种措施进行控制和治理。     

当前人民币汇率制度选择的理论思考

任何汇率制度都只是实现经济目标的手段而不是目的,我们在各个时期选择的汇率制度应该是对我国经济发展最有利的制度。在现有的国际货币体系下,如果资本项目尚未开放,则理性的选择应该是固定汇率制度;如果资本项目已完全开放,则实行浮动汇率制是有效而保险的。对于中国这样一个资本账户部分开放的国家,现阶段重新回到真正意义上的有管理的浮动汇率制是必要的,也是可行的。     

Properties of Census Dual System Population Size Estimators

We study parametric and non‐parametric approaches for assessing the accuracy and coverage of a population census based on dual system surveys. The two parametric approaches being considered are post‐stratification and logistic regression, which have been or will be implemented for the US Census dual system surveys. We show that the parametric model‐based approaches are generally biased unless the model is correctly specified. We then study a local post‐stratification approach based on a non‐parametric kernel estimate of the Census enumeration functions. We illustrate that the non‐parametric approach avoids the risk of model mis‐specification and is consistent under relatively weak conditions. The performances of these estimators are evaluated numerically via simulation studies and an empirical analysis based on the 2000 US Census post‐enumeration survey data.     

人口老龄化背景下的中国养老保险风险分析

伴随着我国人口老龄化的不断加速,社会保障尤其是养老保险领域的压力也随之加大,我国当前的养老保险体系也存在着一些现实问题与不足之处。而这都将导致在养老保险体系中固有的筹资、基金投资运营风险上升,同时也将出现制度与政策等新的风险。文章认为,需加强风险管理,不断完善养老保险制度,才能积极应对风险与收益的平衡。     

A Population Projection for Indonesia, 2010–2035

In the context of its long-term planning, from time to time the Indonesian government publishes an official population projection. The latest projection was released on 29 January 2014. In this article, I describe and evaluate the methods and assumptions used to produce the projection, and provide key results.     

Accounting for breakout in Britain: The industrial revolution through a Malthusian lens

This paper introduces a simple dynamic model to examine the breakout from a Malthusian economy to a modern growth regime. It identifies several factors that determine the fastest rate at which the population can grow without engendering declining living standards. We then apply the framework to Britain and find a dramatic increase in sustainable population growth at the time of the Industrial Revolution, well before the beginning of modern levels of income growth. The main contributions to the British breakout were technological improvements and structural change away from agricultural production, while coal, capital, and trade played a minor role. In addition to solidifying the link between the Industrial Revolution and rising living standards, this research reconciles the gradualist and limited Crafts–Harley view of the Industrial Revolution with a dramatic and rapid change in Britain’s macroeconomic character.     

茭簰考释--兼及江汉平原湖区人水关系

明清时期长江中游地区地方文献记载的茭簰,并非漂浮种植性质的葑田,而是漂浮居住性质的水上居家设施。“随波上下”且“不时迁移”是其基本特性,实质是借水之力以避水之害,乃湖区居民应对洪涝灾害的居住创举。茭簰不同于为众熟知的舟船,亦有别于水上航行的排筏,茭簰居民并非渔民,而是备有“种莳牲畜”的农民。茭簰与葑田,虽然一耕一居,却具有共同的指向。茭簰是湖区农家适应环境变化,根据生产生活需要而做出的相对选择,堪称湖区居民趋利避害、协调人水关系的代表性举措。     

Political budget cycles revisited: Testing the signalling process

A widespread view in the ‘political budget cycles’ literature is that incumbent politicians seek to influence voters’ perceptions of their competence and/or preferences by using the composition of the fiscal budget as a signalling tool. However, little is known about whether voters actually receive and perceive the signal in that way. To empirically assess the relevance of the signalling channel at the municipal level, we conducted a survey among 2000 representative German citizens in 2018. Only a small fraction of voters feel well-informed about the fiscal budget signal and use the information it contains to decide whether to vote for the incumbent politician. Persons paying more attention to the signal sent by local politicians live in smaller municipalities, are more satisfied with their economic situation, are more educated, and do not feel that they are being electorally manipulated. Our analysis raises doubt about the relevance of budget composition as a signalling mechanism for voters at the local level.
