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。     

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.     

中国股市大幅波动期间股指期货对指数现货波动的影响分析

针对股指期货做空机制与做多机制对指数现货的影响有无异同的问题,将2014年7月至2015年8月间中国股市的大幅波动分为上涨期和下跌期,通过沪深300股指期货以及沪深300指数现货每5分钟的数据,利用Garman & Klass波动率度量公式、双变量GARCH模型和EGARCH模型来分析波动中股指期货对指数现货波动的影响。研究认为,在市场处于大幅波动期,股指期货和指数现货两个市场之间存在双向价格引导关系,其中指数现货市场处于主导地位,两个市场之间风险是相互传递的,其中指数现货市场的风险传递更加显著;在中国股市波动的利多阶段,股指期货的负收益会促进指数现货的波动,在利空阶段,股指期货的负收益影响大于正收益影响,股指期货的做空机制对指数现货市场带来的影响大于做多机制带来的影响;股指期货以其本身固有的领先于股指的特性,在应该抑制波动的时候反而加剧了波动,造成了负面影响,中国金融市场应重视其负面影响,并采取有效措施来加强对负面影响的控制。     

集体谈判的内部国家机制：以温岭羊毛衫行业工价集体谈判为例

集体谈判作为西方社会劳资冲突制度化的社会发明,不但得到工人和工会的拥护,同时也引起了雇主的兴趣。通过协商的程序、承诺的遵守以及共同利益的形成,可以构筑消解工人集体怨恨、制造工人认同的内部国家机制。在中国,工会受组合主义限制,尚不能成为集体谈判的有效发起者,愈演愈烈的劳资冲突却有可能使雇主成为实际的“发动引擎”。本文通过对温岭羊毛衫行业工价集体谈判过程的描述,探讨在竞争和斗争的背景下,雇主和工人在集体谈判过程中的互动,以及在以生存伦理为基础的工人群体中逐步形成从“无序抗争”到“有序遵守”的内部国家机制。     

西方国家民意表达的社会化机制研究

西方社会,除了建立起民意表达的国家机制以外,还拥有较完备的民意表达社会化机制。在工具层面,社会化表达机制作为一个结构化体系,涵盖了民意机构表达、大众传媒与出版表达、利益集团与自愿组织表达、街头民主表达以及理论学术表达等多样化的诉愿形式。当今西方社会化机制维度上的民意表达呈现出一些新的特点和趋势,特别值得我们关注,更需要我们放眼世界而寻求经验,以利于构建和谐社会。
