The article compares the incidence of public healthcare across11 Asian countries and provinces, testing the dominance of healthcareconcentration curves against an equal distribution and Lorenzcurves and across countries. The analysis reveals that the distributionof public healthcare is prorich in most developing countries.That distribution is avoidable, but a propoor incidence is easierto realize at higher national incomes. The experiences of Malaysia,Sri Lanka, and Thailand suggest that increasing the incidenceof propoor healthcare requires limiting the use of user fees,or protecting the poor effectively from them, and building awide network of health facilities. Economic growth may not onlyrelax the government budget constraint on propoor policies butalso increase propoor incidence indirectly by raising richerindividuals' demand for private sector alternatives. 相似文献

Chewing gum was foremost an American invention, Michael Redclifttells us in Chewing Gum: The Fortunes of Taste, a brief yetserious and engaging book that details how chewing gum cameto occupy a distinct place in the rise of American consumerism.Perhaps nothing signified the triviality of consumerism as chewinggum. It possessed what Redclift calls an "ephemeral quality,"it was an easily replicable mass product, and provided instantgratification. This ephemerality was complicated by 相似文献

为应对后疫情时代全球电子信息产业加剧的“比较优势陷阱”,中国亟需通过国内价值链省域比较优势的互补协同提升整体国际竞争力。在价值链产品内,基于垂直专业化分工框架,兼顾增值能力与劳动生产率两个维度,使用非竞争型投入占用产出模型,设计一个评测国家内部区域电子信息产业真实比较优势的新指标。结果表明,东部沿海省域比较优势强度与广度最为显著,内陆省域比较优势集中于上游能源型部门;制造业部门比较优势凸显,服务业部门比较优势相对薄弱;比较优势高省域集中度与低省域集中度的产业部门中,均存在整体比较优势强弱差异,其中,高省域集中度产业部门比较优势强度更高。 相似文献

We study the performance reaction of investors in a specific small market context. Our sample includes all Portuguese open-end
equity funds that invested in stocks issued by Portuguese companies in the period December 1993–June 2009. Instead of the
convex flow–performance relationship usually documented for the US, we find an absence of reaction to past performance. We
find no evidence to support the “smart money effect”, given that capital flows do not favour next period performance winners.
We also document persistence of fund flows. Our results are consistent with the idea that large financial intermediaries have
the capacity “to drive” their customers to funds with larger fees. 相似文献

This study has investigated the dynamic competitive relationship between PDP TVs and LCD TVs by means of their quarterly shipments. The renowned Lotka-Volterra competition diffusion model has been adopted to conduct the empirical analysis with the Lyapunov function to carry out equilibrium and stability analysis, and estimate the domain of attraction which describes the trend and phenomenon of TV shipments. The results illustrate that there is good fitting performance while adopting this model. The competitive relationship can be viewed from the perspective that the LCD TV is the prey while the PDP TV is the predator. The possibility, nevertheless, for dropping the price of LCD TVs is an advantage of the attractiveness of the product which can be noted in higher growth rate than PDP TVs. With respect to the equilibrium stability analysis and estimated domain of attraction, 40- to 49-inch PDP TVs will not disappear from the market, but will generate a stable equilibrium with LCD TVs and sales volume presents simultaneous increase or decrease. In the supply and demand analysis, LCD TVs present a surplus of supply from 2008; therefore, how to conduct appropriate inventory management will be an emerging issue. 相似文献

我国国民福祉演进轨迹及其政策效应 总被引:1,自引:0,他引:1
国民福祉可以通过经济、社会、文化、环境等客观指标加以体现。运用国民福祉评价模型对1996~2009年间我国四大区域及全国31个省级行政区国民福祉的时空演进特征进行实证分析,检视我国区域协调发展战略的政策效应,并结合以人为本的科学发展理念和构建和谐社会的目标,提出进一步协调我国区域发展的政策方向。我国在发展经济过程中,应重点关注经济增长对国民福祉的提高程度。 相似文献

本文提出了一种新的混沌扩频序列产生方法。该方法基于神经网络的强大学习能力和副近非线性函数能力,应用具有全局最优的BP改进算法通过训练学习建立起具有混沌性态的优化神经网络模型,利用网络权值调整的灵活性来产生混沌扩频序列。计算机仿真结果表明,该模型产生的混沌扩频序列调整更容易,比基于单一混沌映射能产生更多符合扩频通信要求的扩频序列。 相似文献
