微博时代公共舆论暴力的产生及其治理机制研究

在Web2.0飞速发展的时代,以网络和手机终端为发布平台的微博,凭借其短、平、快等优势,正形成自己独特的“微博舆论场”,成为了社会公共表达的全新平台,在公民参政、民主表达、舆论监督等方面发挥着积极作用。然而,由于网络的匿名性、网民的非理性、监管制度的缺失等原因,网络舆论暴力现象屡见不鲜。构建一套科学的网络舆论暴力治理机制,需要推行微博实名制、强化网民的社会责任感,建立科学的舆情研判与调控机制,加强网络道德建设,完善网络行为的相关立法。     

基于能力和相对业绩比较的经营者激励机制研究

如何激励企业的经营者为股东的最大利益而努力,是现代企业面临的重要课题。为进一步解决经营者的激励机制问题,本文采用数学分析的方法,在不对称信息条件下经营者激励机制的设计中同时考虑了经营者能力和相对业绩比较等因素,使得经营者激励机制的设计更加完善、更加全面。分析结果表明:经营者的经营能力、努力成本、相对业绩比较、风险厌恶程度等,影响经营者的激励合约。     

产品系统生态因子选择动力研究

为了探寻企业实施生态化经营的内在驱动机制,选择竞争性市场结构作为研究背景,把产品系统分割为满足常规功能的普通因子部分和满足生态要求的生态因子部分,而产品顾客则被划分普通型消费者和具有生态意识的责任型消费这两部分.在此基础上引入政策补贴变量,分别从短期和长期两个视角来分析企业产品系统生态化的行为特征.研究发现:在利润目标的驱使下,基于对责任型消费群体规模、自身技术经济实力、政策支持力度等因素的综合考虑,企业对产品系统生态因子比例的选择具有较强的策略性。     

公共治理视域中的西部农村公共文化发展机制研究

农村公共文化建设是复杂的系统工程。构建多元、民主、协作的公共治理模式来建设和管理西部农村公共文化,既要加强内生机制建设,也要完善和促进外生机制建设。内生机制与外生机制两者相辅相成,相互促进,形成西部农村公共文化发展的长效机制,能够有效地解决我国西部农村公共文化有效需求抑制、有效供给不足的难题。     

刘易斯二元经济结构理论与我国现实

刘易斯的二元经济结构理论是建立在以自由竞争为基础的市场经济的基础上。而我国现阶段的市场经济,还称不上是完善的市场经济,只能称为政府主导型的市场经济。刘易斯的二元经济结构理论因此被扭曲为城乡二元经济结构体制。由此而派生的农民工劳动力市场和低附加值劳动密集型产业的大发展以及出口导向型的发展模式。我国农村劳动力无限供给的“人口红利”时代即将结束,“刘易斯拐点”即将到来。我国经济社会发展方式转变的“倒逼机制”越来越强化。建立在农民工劳动力市场基础上的出口导向型发展模式已经走到尽头了。     

The Impact of Internet Use on Residents’ Subjective Well-Being: An Empirical Analysis Based on National Data

Internet use has become an indispensable part of people’s daily lives, and the relationship between Internet use and residents’ subjective well-being is receiving increasing attention from researchers. However, the existing literature on the relationship between Internet use and residents’ subjective well-being is still controversial and inconclusive, and there has been relatively little discussion of the mechanisms by which Internet use affects well-being. On the basis of data from the China General Social Survey 2015 (CGSS2015), this paper provides an empirical analysis of the impact of Internet usage on residents’ subjective well-being. The study finds that while Internet use had no significant impact on the well-being of residents compared to non-use, frequency of Internet usage did significantly improve subjective well-being. On this basis, we tested the mechanisms by which Internet use affects residents’ well-being through the three channels of the personal income effect, the human capital effect and the social capital effect. The findings partially verify the hypothesis of the mediating effect of social capital between Internet use and residents’ subjective well- being, but do not verify the hypothesis of the moderating effect of personal income and human capital. Compared with previous studies, this paper is innovative in the following three ways: it uses the latest available representative national microdata, which is better able to reflect recent Internet usage and its impact on residents’ subjective well-being; on the basis of existing research on the impact of Internet usage on residents’ well-being, it analyzes the specific mechanisms through which Internet use affects well-being, using the moderating effect model and the mediating effect model to make up for the shortcomings of existing research on the impact mechanism; and it applies the Bioprobit model to deal with the potential endogeneity of key explanatory variables, using a variety of model estimation methods to obtain more robust estimation results.     

利益认同与社会主义核心价值认同——以化解社会风险为视域

利益是价值的尺度,可以用利益认同来推动价值认同。党和国家领导人高度重视社会风险问题,化解社会风险可以实现利益认同,进而转化成社会主义核心价值认同。建立利益机制化解社会风险,推动社会主义核心价值认同,体现在四个方面：化解经济风险,巩固核心价值认同的物质基础;化解政治风险,创造核心价值认同的民主前提;化解文化风险,营造核心价值认同的人文氛围;化解公共风险,改善核心价值认同的安全环境。     

成本信息不对称下的应用服务外包菜单式合约

客户企业实施应用服务外包时,面临着成本信息不对称所带来的风险。针对该问题,以客户企业期望收入最大化为目标,在应用服务提供商(Application Service Provider, ASP)所拥有的成本效率参数及努力水平不可观测下研究客户企业如何通过服务外包菜单式合约的设计激励ASP付出最优的努力水平,并显示出真实的成本信息。研究表明,收益共享系数是成本效率参数、风险规避度、产出方差的减函数;客户企业向ASP支付的期望服务报酬除了补偿保留效用与服务生产成本还将额外支付风险成本、信息租金;风险成本随风险规避度、产出方差递增,随成本效率参数递减;信息租金随风险规避度、产出方差、成本效率参数递减。     

坚持“五个统一”,完善理论进基层示范点运行机制

福建省理论进基层示范点建设已取得初步成效,涌现出一些典型,但也存在许多不足。坚持贴进大众与提升认同的统一、凸显特色与思想引导的统一、倾听民声与价值引领的统一、理论宣传与决策咨询的统一、基层实践与高校智力支持的统一,这"五个统一"是新形势下完善理论进基层示范点运行机制的有效途径,也是解决不足的重要手段。     

Bayesian methods for dealing with missing data problems

Missing data, a common but challenging issue in most studies, may lead to biased and inefficient inferences if handled inappropriately. As a natural and powerful way for dealing with missing data, Bayesian approach has received much attention in the literature. This paper reviews the recent developments and applications of Bayesian methods for dealing with ignorable and non-ignorable missing data. We firstly introduce missing data mechanisms and Bayesian framework for dealing with missing data, and then introduce missing data models under ignorable and non-ignorable missing data circumstances based on the literature. After that, important issues of Bayesian inference, including prior construction, posterior computation, model comparison and sensitivity analysis, are discussed. Finally, several future issues that deserve further research are summarized and concluded.
