城市基础设施中政府规制行为研究——以浮动投资回报率担保为视角

浮动投资回报率担保是PPP（Public-Private Partnerships）模式下较为吸引投资的政府担保行为,有利于提高私人机构投资者在城市基础设施项目的建设、管理和运营方面的积极性。以浮动投资回报率下政府担保为立足点,剖析我国浮动投资回报率担保现状,建立浮动投资回报担保模型,探求政府实现私人机构规制的实现途径,即私人机构对城市基础设施的投资回报未达到浮动投资回报区间的,政府进行财政补贴;投资回报达到浮动投资回报担保上限的,政府征收超过上限的超额收益。     

Social Security Green Paper： Community Nursing will be the Preferred Way for Old-age Support in the Future .

正The green paper on social security Report on Social Security Development in China 2014 announced in Beijing on July 1,2014 stated that community nursing would serve as the preferred way for old-age support in the future while there was still a large shortfall in community nursing,which required urgent improvement.Community Nursing Will Be the Preferred Way for Old-age Support in the Future At present,China is facing the severe challenge of population ageing.Elderly aged over 60 years old have     

论唐代后期藩镇对漕运的保障

安史之乱爆发后,安史叛军迅即占领大河南北,以及长安和洛阳等广大地区.漕运线路的安危,时有可虞.为此,沿途藩镇对漕运进行了保障工作,使得江淮等地物资,源源不断输至中央,支援了中央的平叛战争.安史之乱以后,一定时期内,因漕运线路经由的部分区域,仍然受到叛镇的控制或威胁.所以,保障漕运线路的安全,依然是相关藩镇的重要任务.唐后期,藩镇对漕运线路保障的基本得力,有效地延续了唐王朝的统治.     

BOT模式--民间资本参与西部大开发的选择途径

西部基础设施建设是西部大开发的重要内容.资金短缺是西部基础设施建设的困境之一.目前国家正常渠道不能满足西部建设的资金需要,银行等金融机构也谨慎操作.而巨量的民间资本却寻找不到满意的投资去向.如何将这两方面有效整合,关系到我国经济的可持续发展.本文认为,BOT方式为民间资本参与西部基础设施建设提供了合理途径.只要政府积极引导,以BOT方式参与西部建设的民间资本会发挥越来越大的作用.     

交通部与民初邮政基础设施建设述评

交通部对民国初年我国邮政基础设施建设的推进作用,主要体现在三个方面：第一,邮政局所建设方面,各邮局总数皆呈明显上升趋势,支局、邮政代办所和次要局所数目增加十分明显。第二,邮政线路规划方面,邮差线增长最快,航船线次之,铁路线即铁路里程数相对保持稳定。第三,邮政运具发展方面,车辆包括铁路邮用行车、邮用自行车,另有船舶及骡驼等形式,均有相当发展。总之,交通部极大地推动了我国邮政事业的现代化。     

Optimal Design of a Two-Level Transportation Network with a Different Unit Cost for Each Secondary Link*

The objective of this paper is to further develop Singhal's (1990) framework for designing a two-level hierarchical transportation network consisting of a trunk or primary link and several feeder or secondary links. Secondary links are perpendicular lines from each of the given points and the primary link is a straight line or curve connecting the feet of two extreme perpendicular lines. The problem and the associated strategic and operational considerations such as cost, time, feasibility, and preferred regions for the primary link in the context of rural highway planning are discussed. Two-level networks are also common in electricity transmission, pipelines, and telecommunication design. The core of the framework is a model for finding the path of a primary link such that a weighted sum of the lengths of the perpendicular lines from each point to a linear primary link and the distance between the feet of the two extreme perpendicular lines is minimized. The analysis shows that for almost every problem there exists a wide range of solutions for which the total cost is only slightly higher than that of the optimal solution. This offers considerable flexibility to the decision maker. These solutions can be evaluated in view of the broader objectives and constraints that are not included in the model. The use of computer graphics and the option of a nonlinear or piecewise linear primary link are also discussed.     

Zine infrastructures as forms of organizing within feminist social movements

This paper explores how feminist social movements are organized and re-generated across and through different media, both online and offline, using the example of zines. We critically examine the emergence and growth of an intersectional feminist zine community through a 6-year in-depth qualitative netnographic and ethnographic study. Theoretically, we build on work concerning feminist digital information and archival infrastructures, bringing it together with work on feminist digital activism. We make three key contributions: first to theorize zines and their communities as infrastructures, which cut across the social, digital, and material. Second in understanding the political potential of engagements in zine infrastructures in which the individual and collective are entangled, and third in revealing how the current generation of young feminists move across and work at the interfaces of formats to benefit from their synergistic, but also their agonistic, relations to form new affective solidarities.     

信息基础设施与经济增长——基于中国省际数据分析

利用2001年至2008年中国31个省、直辖市和自治区的面板数据验证信息基础设施对中国经济增长的影响,并在此基础上分析信息基础设施对中国不同区域经济增长贡献的大小.基于宏观总产出方程与信息基础设施微观供需模型相结合的联立方程模型控制信息基础设施内生性,采用人均长途光缆线路长度作为信息基础设施的代理变量测度信息基础设施对经济增长的贡献.实证研究结果表明,信息基础设施对中国的经济增长有显著的正向促进作用,基于信息基础设施对各地区经济增长的复合增长效应的测算表明,信息基础设施对中国经济增长有很大贡献,但是信息基础设施对不同区域增长的贡献与经济增长的状况却存在反差.在西部不发达地区,信息基础设施的发展对经济增长的促进作用要高于全国水平,而中部各省信息基础设施的发展却低于全国水平.     

农业基础设施供给的多中心协同机制研究

在对农业基础设施产品属性、收益区域性进行分析的基础上，界定农业基础设施各供给主体的责任、范围及农业基础设施的供给方式，以构建农业基础设施多中心协同供给体系。纯公共物品及公共池塘物品属性的农业基础设施的主要供给方式是机构型供给，通过成立专委会实现科层制协同。俱乐部物品属性的农业基础设施的主要供给方式是政府与企业联合供给，政府与企业通过公私协同实现农业基础设施的有效供给。村庄范围的公共池塘物品属性的农业基础设施通过战略性协同、沟通性协同以实现政府与农民联合供给或农民自治供给。受益范围为村小组或几户的农业基础设施以农民自治供给为主，通过沟通性协同使农户能顺利实现合作供给。私人物品属性的农业基础设施由企业供给或农户自己供给以实现资源的最优配置。
