房价上涨对我国人口出生率的影响——基于省级面板数据的实证分析

人口数量和结构是影响我国可持续发展的关键因素,住房是人民群众安居乐业的刚需。近年来,我国人口出生率持续下降。为了实现经济高质量发展,缓解人口危机是当前亟待解决的重要问题。为了探究房价上涨对于我国人口出生率的影响,利用31个省级行政区2010—2019年的面板数据和加权最小二乘法进行实证分析,结果表明：房价上涨对人口出生率产生显著的负向影响,住房价格平均上涨1%将导致人口出生率下降0.13%~0.22%;房价上涨对人口出生率的影响在东部省份以挤出效应为主、在中西部省份是以财富效应为主。当前,通过遏制住房投资投机性需求、给予“刚需”人群购房贷款优惠、适量增加东部省份土地供给等手段,可以助力解决我国当前的人口问题。     

The Seveso Directive: An Italian Pilot Study in Enabling Communication

In 1982 the Council of the European Communities issued a Directive on the Major Accident Hazards of Certain Industrial Activities, commonly known as the Seveso Directive. Besides other requirements, the Directive specifies that members of the public liable to be affected by a major accident from certain industrial activities must be informed of safety measures and how they should behave in the event of an accident. The Directive was subsequently amended in an extensive way. Upon the transposition of the Seveso Directive and its amendments into national legislations, the 12 European Member States are faced with the task of "appropriately and effectively" informing the public about major accident hazards. Delays are observed throughout the community, both in transposing the Directives and implementing public information. A pilot study on "Risk Information Needs" was commissioned and carried out at two Seveso sites in Italy in order to begin to resolve some of the problems involved in the provision of public information and to suggest appropriate guidelines. One hundred subjects answered an experimental protocol designed to assess their "information needs." This article presents the theoretical background, the pragmatic aims, and the design of the study. It also summarizes its most relevant findings and suggests some recommendations for the provision of information to the public.

Tolerable or Acceptable: A Comparison of Risk Regulation in the United Kingdom and in the Netherlands

In managing major accident hazards in industry risk, both the United Kingdom and the Netherlands use quantitative risk analysis and quantified risk criteria. These should be understood in the historical, legal, and political context in which they were drawn up. Even when criteria are numerically the same they do not necessarily mean the same thing. The legal and historical context differs widely between the two countries. Nevertheless, it is surprising that the final results in terms of land use and levels of risk are very similar.     

Industry and the environment: a case study of cleaner technologies in selected European countries

The aim of this case study is to discuss the role of technology in addressing environmental problems. The paper tries to scratch beneath the surface of the increasingly frequent ‘quick-fix’ solutions to the present environmental problems, based on such beguiling catchwords as Cleaner Technologies, Best Available Technologies, and Best Available Technologies Not Exceeding Excessive Costs, etc., in an attempt to discover whether there is any substance in them, or whether they are just full of hot air. Recent data from case studies performed by the author in Germany and Finland as well as a postal questionnaire in Denmark are presented. The paper analyses and discusses the roles and responsibilities of designers, industrialists, and government policy-makers. It is argued that existing regulatory regimes, supranational industrial structures, and market mechanisms do not favour the development of cleaner technologies, nor do they promote a reduction in consumption patterns. Evidence from ongoing empirical research in Northwest Europe suggests that industry is far from developing and/or implementing cleaner technologies. The paper closes with a discussion of some of the policy implications involved and some examples of urgently needed further research.     

基于反向物流的商品定价和退货政策研究

综述了基于反向物流的商品定价和退货政策的最新研究成果。在此基础上,通过建立模型,对基于反向物流的商品定价策略和退货政策进行了进一步的研究,并求出了商品的最优价格和最优退货价格。基于模型,对管理提出了一些建议。最后指出了将来可能的研究方向。     

带有快速反应策略供应链系统的补偿策略研究

过长的订购提前期往往使得零售商订货决策感到困难. 快速反应策略能使零售商在获 得更多更准确的市场需求信息后,调整订购量而提高收益. 但是快速反应策略并不一定使供应 商的利润也提高. 有文章指出只有低的服务水平才能使两者利润同时提高,因而这种方法在工 业应用中是不一定可行的. 补偿策略是一种广泛应用的方法,能够提高产品的客户服务水平, 因而研究了补偿策略在快速反应供应链系统中的作用. 在某些条件下,在快速反应供应链系统 中,补偿策略能使零售商与供应商一方的收益不变或者提高,另一方的收益有所提高,即Pare2 to 提高. 还研究了引进补偿策略后,供应链系统的最优解及期望卖出量、期望缺货量和期望残 余量的变化情况.     

国有资本收益收取政策对央企上市公司现金股利影响研究

自2007年国务院出台中央企业国有资本收益收取办法以来,经过2010年和2014年的连续调整,国有资本收益收取初步形成了一套制度体系,影响力也在不断扩大。在这样的背景之下,央企上市公司的现金股利政策是否受到国有资本收益收取政策的影响、国资收益收取比例是否合理值得进一步探究。基于代理理论对国有资本收益收取政策和上市公司现金股利政策的关系进行了理论分析并提出研究假设。研究结果表明,上市公司现金股利政策不仅受到传统的公司特征以及公司内部治理特征因素的影响,还受到宏观政策的制度因素的影响。     

会议外交与中国参与全球卫生治理的思考

在全球卫生领域以大型会议为代表的国际会议外交已成为全球卫生治理的一种重要形式和载体。文章梳理了全球卫生治理中会议外交的两方面体现,一是以国际会议为代表的会议外交与全球卫生治理,二是以国家行为体为代表的会议外交与全球卫生治理,并进一步归纳了会议外交促成的全球卫生治理进程,包括多次会议促成了全球卫生安全的国际规则《国际卫生条例》,以及历经多年会议磋商促成了全球人口覆盖范围广的《烟草控制框架公约》。中共的十九大报告中对外交工作和健康中国战略有了明确表述,由此需要卫生与外交工作者审时度势、认清角色,通过会议外交表明态度,并以全球卫生会议外交为起点,促进国内立法接续。     

角式调节阀两相流模拟与结构改进

基于2003—2015年我国26个省、自治区的面板数据,重点考察了四万亿投资刺激计划背景下,各地区的财政货币政策对粮食价格波动的冲击效应及其差异。研究发现：中国粮食价格上涨除了受到生产成本因素驱动以外,还主要受到宽松的货币政策所引致的地方流动性过剩的影响,地方财政货币政策对粮食价格波动的冲击效应在四万亿投资实施前后存在明显的差异;四万亿刺激计划实施后,各地区积极的财政政策和宽松的货币政策才是新一轮粮食价格波动的主因,粮食类农产品因为自身的敏感和脆弱性,受到了财政货币政策引致的流动性泛滥所带来的最直接伤害;应注重财政货币政策的多重目标分解、梳理及协调配合,处理好“稳增长、控物价、调结构、惠民生、防风险”之间复杂多变的关系,寻求一个有效的“平衡点”。
