20世纪中叶以来中国农民五次大解放及其特点

20世纪50年代以来,农民问题一直是中国社会经济发展的重大问题,处理好农民问题有利于处理农村生产关系与生产力相适应的关系问题,解放农民即解放和发展农村的生产力.从上世纪50年代开始的土改,到80年代的农村家庭承包制的改革,再到90年代的全面推行村民自治制度和直接民主制度,以及21世纪初农村城乡协调发展改革等举措,使得农民获得五次大的解放.本文就我国农民的五次大解放进行总结与回顾,并分析了每一次农村大变革的基本特点,这对完善农村的改革具有重要的意义.     

对当前中国启动内需的思考

当前国内经济下行与产能过剩,根源在于内需不足与出口主导型战略下西方负债型消费模式,导致中国产业规模过度扩张与产业结构失衡.启动内需是大国经济增长和稳定的基石,应该作为国家长期战略来贯彻执行.启动内需不是由政府代替消费者来花钱,而是重在构建经济持续健康发展的体制环境.中国应进行产权制度的改革创新,降低税收并减少由政府主导的投资;建立健全社会保障体系,稳定物价水平;创新金融体制,完善市场机制,营造有利于创业就业的体制环境;大力发展农村经济,提高农民收入;扶持中小企业的发展;大力发展服务业,促进消费转型.     

Parallels Between Objective Indicators and Subjective Perceptions of Quality of Life: A Study of Metropolitan and County Areas in Taiwan

This study explores the consistency between objective indicators and subjective perceptions of quality of life in a ranking of survey data for cities and counties in Taiwan. Data used for analysis included the Statistical Yearbook of Hsiens and Municipalities and the Survey on Living Conditions of Citizens in Taiwan, both given for the year 2000. The Quality of life was examined in seven domains: medical services, domestic finances, work, education, leisure, public safety, and environmental quality. Subjective and objective rankings for each domain of quality of life for 23 areas (some areas are cities and some are counties) are compared. Analysis by means of nonparametric correlation coefficients indicates that there is no significant correlation between objective indicators and subjective perceptions, except in Education and Environmental Quality. Objective indicators of Environmental Quality (air pollution and garbage) are positively correlated with subjective satisfaction with residential environment. But inexplicably, higher levels of literacy and educational achievement are negatively correlated with satisfaction with the educational system. It may be considered that disparity in either average objective conditions or in average subjective perceptions may not adequately depict quality of life differences.

低生育水平下的生育成本收益研究——来自江苏省的调查

文章应用江苏生育意愿与生育行为调查结果,研究符合二孩生育政策妇女的生育行为、生育计划和生育观念,主要从妇女的角度分析生育威本和生育收益,并应用多元统计分析方法重点分析生育成本对妇女生育计划的影响.研究发现,育龄妇女大多认为满足精神需求是最重要的生育理由,而第二个孩子的养育成本是主要考虑因素.在控制了年龄、受教育程度、居住地、户口性质、婚姻状况、生育观念等特征后,生育的经济成本和心理成本对妇女生育二孩的计划有显著影响.     

人力资源综合素质评价及区域分异研究——以陕西省为例

人口的综合素质是区域社会经济发展的根本保证,人口的规模、素质和结构与社会经济发展、生态安全有着密切的关系。本文构建了陕西省人力资源综合素质评价指标体系,运用因子分析法对影响人力资源综合素质的指标进行降维处理,确定了四个与人力资源素质密切相关的因子。分别是收入水平因子（LOIF：The Level Of Income Factor）、医疗条件因子（MCF：Medical Condition Factor）、科教文化因子（SECF：Science and Education and Cultural Factors）、非农产业因子（NAIF：Non-Agricultural Industries Factor）;并计算了各市在各因子上的得分,从而得到了人力资源综合评价指数（HREI：Hunlan Resources Evaluafion Index）;利用SPSS构建了因子与地区经济发展水平（GDP）间的逐步回归模型：运用系统聚类法将人力资源综合评价指数与影响因子分为4类;在ARCGIS支持下制作了陕西人力资源综合素质评价图．从而揭示了人力资源综合素质的空间差异。     

A study of quadratic inference functions with alternative weighting matrices

Quadratic inference function (QIF) is an alternative methodology to the popular generalized estimating equations (GEE) approach, it does not involve direct estimation of the correlation parameter, and thus remains optimal even if the working correlation structure is misspecified. The idea is to represent the inverse of the working correlation matrix by a linear combination of some basis matrices. In this article, we present a modification of QIF with a robust variance estimator of the extended score function. Theoretical and numerical results show that the modified QIF attains better efficiency and achieves better small sample performance than the original QIF method.     

Pricing power options with a generalized jump diffusion

In this article, the valuation of power option is investigated when the dynamic of the stock price is governed by a generalized jump-diffusion Markov-modulated model. The systematic risk is characterized by the diffusion part, and the non systematic risk is characterized by the pure jump process. The jumps are described by a generalized renewal process with generalized jump amplitude. By introducing NASDAQ Index Model, their risk premium is identified respectively. A risk-neutral measure is identified by employing Esscher transform with two families of parameters, which represent the two parts risk premium. In this article, the non systematic risk premium is considered, based on which the price of power option is studied under the generalized jump-diffusion Markov-modulated model. In the case of a special renewal process with log double exponential jump amplitude, the accurate expressions for the Esscher parameters and the pricing formula are provided. By numerical simulation, the influence of the non systematic risk’s price and the index of the power options on the price of the option is depicted.     

城中村农民社会研究的人类学维度与限度

从人类学的角度来看,城中村的农民、农业、农村社会变迁和包括少数民族在内的大量外来务工人员的文化移植或嵌入,共同构筑了城中村农民社会的文化多样性.人类学独特的理论视角和方法技术,可避免其他学科可能出现的“文化解释”谬误.文章分析了社会情境影响下的中国人类学发展状况和人类学参与城中村农民社会研究的学科优势,从都市人类学、工商人类学、经济人类学、教育人类学、医学人类学、宗教人类学、历史人类学、旅游人类学等8个分支学科讨论了人类学的研究维度,也讨论了人类学参与研究中存在超域性、局部性和相对性限度,揭示了人类学参与城中村农民社会研究的重要意义.
