1990—2010年中国人口预期寿命与人均GDP的相关关系及其变化特征

预期寿命是反映人口寿命水平的重要指标,人均GDP是反映经济发展的重要指标。采用相关分析和回归分析对中国1990—2010年市域、县域两个尺度的预期寿命与人均GDP的关系进行分析,结果表明:人均GDP对预期寿命具有显著正向影响,但累积影响强于即时影响;人均GDP超过3000~5000元后,其对预期寿命的影响开始出现边际递减效应;人均GDP对预期寿命的影响强度在空间分布上自东向西增强。由于经济相对发达的东部地区人均GDP对预期寿命的贡献率要小于经济相对落后的西部地区,因此,今后东部地区应通过完善社会保障、优化卫生资源配置、倡导健康生活方式等途径进一步提高预期寿命,西部地区则应大力发展区域经济,努力提高生活水平,以尽快缩小与东部地区预期寿命的差距。     

Are living standards converging?

We re-address the convergence issue that is so prominent in the economic growth literature and present evidence as to what extent there is convergence across measures of living standards, alternative to capita income. The four additional indicators that we use are daily calorie supply, daily protein supply, infant mortality rates, and life expectancy at birth. We present results obtained using three techniques previously considered in growth empirics. These are cross-country regressions, distributional dynamics, and cluster analysis. Our main finding is that convergence in real GDP per capita does not imply convergence in other social indicators. However, the qualitative results for all indicators are the same in the sense that the persistent gap between the rich and poor does not only manifest itself in real GDP per capita but also in living standards.     

International Comparisons of Living Standards by Equivalent Incomes*

We propose a measure of living standards for international comparisons. Based on GDP per capita, the measure incorporates corrections for international flows of income, labor, risk of unemployment, healthy life expectancy, household demography and inequalities. The method for comparing populations that differ in some non‐income dimension consists of computing the equivalent variation of income that would make each population indifferent between its current situation and a reference situation with respect to the non‐income dimension. This is applied to 24 OECD countries. The obtained ranking of countries differs substantially from the GDP ranking.     

谈人类发展指数的理论评价与应用

人类发展指数(HDI)从人本主义出发,取代传统的片面追求经济增长,单纯比较人均GDP的方法,更加全面科学地为各国的发展实践提供了衡量的标准;同时,可以通过对这个指标体系中各项分指标进行分析比较,发现与别国的差距,以进一步改良政策,使本国的经济和社会都能够更健康地发展,尤其无论从理论上还是指标设计上都可以为我国建设和谐社会和实现经济可持续性发展的目标服务.就人类发展指标体系的创建进行阐述,然后对其包含的发展思想进行理论评价,最后以中国的发展实践中存在的问题进一步证明研究和重视人类发展指数的意义.     

使用人类发展指数对中国城乡差距的一种估计

本文在收集整理反映我国城乡收入、教育和出生时预期寿命差别数据的基础上 ,利用UNDP的人类发展指数法计算了按城乡分的收入指数、教育指数和出生时预期寿命指数 ,并进一步构建了按城乡分的人类发展指数。基本结论是 ,自 2 0世纪 90年代以来 ,城乡收入差距始终是最大的 ,而且呈现出整体扩大的趋势 ;城乡教育差距要小于收入的差距 ,城乡教育上的差距呈现出整体缩小的趋势 ,差距扩大主要表现在义务教育以后的阶段 ;城乡人口出生时预期寿命指数间的差距始终是最小的 ,然而这个差距却在扩大。     

Migrant Age Profiles and Long-Run Living Standards in Australia

The age profile of immigration to Australia can be altered by public policies. This article applies a method of valuing long term population paths in order to evaluate alternative immigrant age profiles based on a proxy indicator of living standards over time for Australia. Results show that the variation in value of the population path follows an inverted U-shape by immigrant's age. The strength of preference between immigrants aged 20–29 years and older working age immigrants reduces as the social discount rate increases. Higher life expectancy and lower fertility accentuate preference for younger working age immigrants.     

Life expectancy, human capital, social security and growth

We analyze the effects of changes in the mortality rate upon life expectancy, education, retirement age, human capital and growth in the presence of social security. We build a vintage growth, overlapping generations model in which individuals choose the length of education and the age of retirement, and where unfunded social security pensions depend on workers' past contributions. Social security has a positive effect on education, but pension benefits favor reductions in retirement age. The net effect is that starting from a benchmark case, higher life expectancies give rise to lower per capita GDP growth in the presence of social security as the share of the active population is reduced. In addition, higher social security contribution rates reduce the growth rate of per capita GDP.     

LIFE EXPECTANCY AS AN INTEGRATING CONCEPT IN SOCIAL AND DEMOGRAPHIC ANALYSIS AND PLANNING1

This paper considers the need for a more integrated system of social and demographic statistics than SSDS and discusses the advantages of building it on the concept of life expectancy. The system would include a network of additive tables which would (as SNA does for economic variables) bring together leading social variables in a way that would permit the effects of exogenous changes to be quantified and compared. The author proposes as the base of such a system a table giving the expected duration of various life states (education, employment, retirement, etc.). This would be supplemented by a family of social co-efficients and fixed-weight index numbers that slot into it, allowing inter-temporal and international comparisons. The system would facilitate analysis of inequalities (regional, ethnic, etc.) and social change, and government planning of such change. It would also provide a framework for the development of national systems of social statistics.     

Measuring Socio-Economic GENDER Inequality: Toward an Alternative to the UNDP Gender-Related Development Index

This paper assesses the United Nations Development Program’s (UNDP) Gender-Related Development Index (GDI). Although the GDI has increased attention on gender equality in human development, it suffers from several limitations. A major problem is that it conflates relative gender equality with absolute levels of human development and thus gives no information on comparative gender inequality among countries. Using the same indicators as the GDI, the paper constructs a Relative Status of Women (RSW) index, which demonstrates how using a measure of gender equality that abstracts from levels of development results in very different country rankings. However, the RSW is not an ideal measure of gender inequality. The GDI indicators are not the most appropriate ones for measuring gender inequality and hence both the RSW and the GDI have limited validity. The paper concludes by offering a conceptual framework that provides the basis for an alternative measure of gender inequality.     

气候变化对干旱区居民生计脆弱性影响研究——基于新疆和宁夏两省区的农户调查

气候变化是导致干旱区居民生计脆弱性的重要原因之一。构建生计脆弱性指标(Livelihood Vulnerability Index,LVI-IPCC)可以评估气候变化对干旱地区居民生计的影响。根据IPCC定义气候变化脆弱性的三个特征,选择新疆、宁夏两个典型干旱省份,调查社会人口指标、生计情况、社会关系网络、健康、食品、饮水安全、自然灾害和气候变化等数据,用复合指标和脆弱性指标进行对比分析。结果表明,宁夏在水资源、健康等方面的脆弱性更为明显,而新疆在社会关系、自然灾害和气候变化等方面更为脆弱。这种实证方法可用于被监测脆弱性,在缺乏地区性数据时检验某种政策的有效性。     

Preference densities and social choices

We discuss a ranking method that allows social pairwise rankings of alternatives to depend on more than just individuals’ pairwise rankings. This violates Arrow’s Independence of Irrelevant Alternatives, but allows Borda’s rank-order counting, which provides a limited accounting for individual preference intensities. We capture Arrow’s rules (i.e., with IIA) and Borda’s method as two polar cases, and allow cases in between. Our main result provides the critical line dividing those degrees of intensity, or preference density, that yield positive results from those that yield negative results. We thank two referees for helpful comments.     

关中—天水经济区人类发展水平空间差异分析

以人类发展指数(HDI)为测度指标,利用HDI计算公式及ESDA方法,对关中-天水经济区65个区县的人类发展水平进行空间差异分析及空间关联分类。关中-天水经济区人类发展水平大多数处于中下水平,且区域差异明显,呈现由市辖区向周边区县递减的分布特点;构成人类发展指数的三个指标中预期寿命指数和教育指数的区域差异较小,而GDP指数区域差异大;关中-天水各区县的人类发展指数存在较强的正的空间相关性,西安市的雁塔区、未央区、莲湖区、碑林区等9个区县成为高-高聚集型区县的显著性聚集区,而天水市的张家川、清水县、秦安县和宝鸡市的陇县等6个区县成为低-低聚集型的最显著区域。针对关中-天水经济区人类发展水平的区域差异,提出相应的政策建议。     

基于经济指标构建的社会稳定风险评估研究

本文选用人均GDP、 GDP增速、基尼系数、物价指数和失业率等5项经济指标对社会稳定风险进行了评估,结果表明：国际横向比较,我国社会稳定程度目前处于中等偏上水平,主要得分在高速的GDP增长、较低的物价指数和失业率方面;自身纵向比较,我国社会稳定风险近年呈加大趋势,主要失分在贫富差距扩大和通货膨胀压力上升方面。笔者的分析结果显示,确保在贫富分化项上不再失分甚至有所加分,即确保贫富差距不再扩大并力争有所缩小,对于保持社会稳定极其重要。     

Nonmarket benefits of nature: What should be counted in green GDP?

Green gross domestic product (green GDP) is meant to account for nature's value on an equal footing with the market economy. Several problems bedevil green GDP, however. One is that nature does not come prepackaged in units like cars, houses, and bread. Even worse, green GDP requires measurement of the benefits arising from public goods provided by nature for which there are no market indicators of value. So what should green GDP count? That is the subject of this paper. Ecological and economic theories are used to describe what should be counted—and what should not—if green GDP is to account for the nonmarket benefits of nature.     

人口预期寿命与退休年龄

人口寿命的不断延长给中国养老事业带来越来越大的压力.文章在两期交叠世代模型的基础上引入退休,在市场完全竞争、充分就业和政府能够控制退休年龄的假设前提下,在个人、企业和政府的行为以及资本市场均衡的层面构建了一般均衡的模型框架,从社会计划者的角度发现福利最大化下的人口预期寿命变化和退休年龄是正相关的,并呈现出负反比例的函数形式.文章还基于参数估计和赋值模拟的方法,求解出了人口预期寿命与退休年龄的调整算法,并以此给出了两者间的调整对照表.根据计算的结果和预期的寿命,建议2030年前逐步将退休年龄延长至65岁.最后通过检验发现,如果不存在人口预期寿命和退休年龄之间的调整机制,在保持养老金收支平衡的前提下,预期寿命的延长将减少养老金的发放,并可能带来社会福利的损失.因此,在中国人口预期寿命不断延长的背景下,建议政府考虑建立人口预期寿命和退休年龄的调整机制.     

The tyranny of international index rankings

International index rankings are popular, but perhaps too persuasive. They emphasize country differences where similarity is the dominant feature. Rankings based on Doing Business, the Human Development Index and Freedom House can be misleading, not because of wrong indicators, but because the estimation of the scores ignores inherent uncertainty. Re-estimated with a method that captures this uncertainty, it becomes clear that ranking every adjacent country is a rather courageous activity.     

基于灰关联分析的中美社会物流成本比较研究

本文从中美两国社会物流成本入手,阐述了中美社会物流成本构成内容及其差异;应用灰关联分析方法分析了1996-2010年中美两国物流总成本、运输成本、存货持有成本、物流行政管理成本与GDP灰关联程度、差异性及其成因,深入了解社会物流成本构成中的哪些因素与GDP 之间的动态过程发展态势的量化比较和关系密切程度,在此基础上提出了降低我国社会物流成本的对策建议.研究结果显示:中国物流总成本及三方面成本构成占GDP的比例呈下降趋势,但与GDP的关联度均高于美国的相关数据,且中国的存货持有成本、运输成本与GDP关联度分别高出美国这两项指标的50.08%和19.49%.因此,降低社会物流成本,优化社会物流成本结构,将是促进我国物流发展的关键问题之一     

The ‘Troubling Tradeoffs’ Paradox and a Resolution

Ravallion ( 2012a ) argues that the Human Development Index (HDI) embeds questionable tradeoffs between the dimensions used to compute the index. To alleviate these problems he proposes the adoption of one of the indices developed by Chakravarty ( 2003 ). In this paper I identify the following paradox: while the Chakravarty indices clearly exhibit more sensible tradeoffs than the HDI, the HDI produces more sensible rankings than the Chakravarty indices. To solve the paradox I identify the axioms behind each methodology responsible for the unintuitive tradeoffs and rankings and illustrate how to develop an index with these questionable axioms removed. This approach can result in methodologies that exhibit more intuitive tradeoffs by design, as it seeks inputs from the public as to what those tradeoffs ought to be, and produces rankings that are more in line with what the HDI wishes to measure: human development and capabilities, as conceptualized by Sen ( 1985 ).     

LIFE EXPECTANCY AND ECONOMIC WELFARE: THE EXAMPLE OF AFRICA IN THE 1990s

A formulation for incorporating Life expectancy information into empirical economic welfare calculations is presented. In an application analyzing the economic progress of the African continent during the 1990s due consideration of life expectancy factors substantially modifies the conclusions drawn from standard welfare calculations.     

预期寿命延长促进经济增长了吗 ——基于全球121个经济体的实证分析

随着社会进步和生活水平的不断提升,人口预期寿命逐渐延长,全球人口老龄化程度亦不断提高,但这并非意味着人口红利的消失。本文基于1996—2017年121个经济体的面板数据,使用动态面板GMM估计方法分析了预期寿命与经济增长之间的关系。实证研究发现：（1）预期寿命延长对经济增长具有促进作用;（2）纳入收入与预期寿命的交互项后,预期寿命显示出对经济增长的制约作用,而收入水平的提高则中和了这种制约作用,带来经济增长水平的提高;（3）不同性别的预期寿命对经济增长的影响具有异质性。基于此,本文从提高居民可支配收入与提高人力资本水平方面提出了相关的政策建议。
