人口集聚与雾霾污染:基于生存型消费视角

以居民衣食住行等生存型消费为视角,利用地级市人口数据构造了30个省份人口集聚指标——省际蔓延指数,采用空间杜宾模型考察了人口集聚对雾霾污染的直接、间接影响及其影响的异质性。研究表明,省级层面的人口集聚有助于直接缓解雾霾污染,但人口过度向省内中心城市集聚却不利于缓解雾霾污染;人口集聚将通过生存型消费各构成项间接影响雾霾。其中,人口集聚引致的食物消费增加会间接促进雾霾污染减少,但人口集聚引致的衣着、居住和交通通信消费的增加却会间接加剧雾霾污染,衣着、交通通信消费与雾霾之间均呈倒"U"型曲线关系;由人口集聚引致的生存型消费项的变化对雾霾污染的影响存在显著区域差异。因此,从人口与消费综合方向强化区域联防联控政策有助于防治雾霾。     

刘易斯模型及相关争论的评析

自1954年刘易斯发表其经典论文以来,围绕该文及其模型在一些基本而又核心的问题上都有很多争论。本文以刘易斯文本为依据,主要对刘易斯模型中两个部门划分、劳动力剩余与生存工资、古典主义方法论及模型中的福利问题等这些基本问题及相关争论进行了评介;并对基于刘易斯模型的发展,尤其费-拉模型的主要贡献进行了评论,在厘清他们之间的联系的同时,也对长期以来存在的一些误解作了纠正。     

甘肃省农村低保标准实证分析及对策研究

甘肃省是典型的西北欠发达省份,基于ELES模型,从马斯洛需要层次理论出发,采用2010-2014年甘肃省农村居民收入和消费的截面数据,测算甘肃省农村低保标准,并引入恩格尔系数算法检验测算结果;发现甘肃省农村低保实施取得了长足进步,但是仅能满足食品需求的现行农村低保标准仍处于较低水平,且存在范围广、水平低的不合理现象,现行单一的农村低保标准无法满足需要的异质性等问题;提出了转变理念、创新方式、走积极的低保道路,建立低保标准与保障水平间的平衡关系,构建多层次低保标准体系,强化农村低保基层工作建设等对策。     

中国的反倾销现状与对策

激烈的市场竞争 ,使得现代企业面临极大的生存困境 ,解决此问题的方法就是创新。创新来源于知识 ,为了实现持续的创新 ,必须进行有效的知识管理。进行知识管理 ,应进行合理的分工 ,才能加强各专业知识的积累 ,以利于人力资源的开发与利用。但过细的分工会人为地隔离各专业知识     

人权理念下的农民土地权利保护

研究目的:以中国首部《国家人权行动计划》(2009—2010年)确立的农民土地权利保障目标为依据,探究人权理念下农民土地权利保护的应有完善。研究方法:人权法与物权法交叉视角下的文献资料法,规范分析与实证分析相结合。研究结果:农民土地权利具有特殊的人权价值,虽然对其保护取得成就,但其进步中的问题仍然突出,以征地和乡土势力严重侵害农民土地权利并影响农民的生存与发展为甚。欲充分保障农民在土地上的人权,必先寻求此问题的破解之道。研究结论:在尊重和保护农民人权的时代诉求下,农民土地权利的保护更需不断强化赋权后的维权功效、充分实现征地中的还权于民。     

Adoption of multiple electronic marketplaces: Antecedents from a grounded theory study

To achieve economies of scope, most motor carriers combine long-term contracts with shippers and brokers with periodic spot assignments found on electronic marketplaces (EMs). While previous research has addressed how carriers adopt an EM, we know little about factors that influence carriers to adopt multiple EMs. Given the rise of the platform economy of the trucking industry, we chose to address this gap and generate mid-range theory on adopting multiple EMs in a logistics context. To do this, we applied grounded theory and conducted 23 interviews with motor carriers and EM experts in North America and Europe until we reached theoretical saturation. Our findings reveal that many motor carriers adopt a portfolio of different EMs, and that their awareness of platforms, expected and realized benefits, attitude, and vigilance determine how they configure their EM portfolios. The implication for existing theory is that, while previous studies depicted EM adoption from a single-system perspective, we found that it is actually a continuous selection process that follows a portfolio perspective. Our paper also has implications for practice in that it illuminates the rationales behind EM portfolio development and identifies actionable factors that can help managers configure stronger portfolios.     

What the subsistence marketplaces stream is really about: Beginning with micro-level understanding and being bottom-up

This commentary reiterates the essence of the subsistence marketplaces stream in light of the focal paper. The subsistence marketplaces stream provides a granular, micro-level understanding of the intersection of poverty and marketplaces. The term ‘subsistence marketplaces’ was deliberately coined to keep the focus on preexisting marketplaces to learn from in order to design solutions for all contexts. Such marketplaces should be studied in their own right, and not as a means to a preconceived end, whether it be for outside companies or government policy and so forth. We study subsistence marketplaces inside-out rather than outside-in – beginning at the micro level and being bottom-up in deriving implications for many sectors of society. We traverse a journey which is in the opposite direction to beginning with ideological lenses, wherein we have developed an ecosystem of research, forums, curricular innovations and community outreach.

Semi‐Subsistence Farming: An Elusive Concept Posing Thorny Policy Questions

The massive expansion of semi‐subsistence farming in the European Union after the Eastern enlargements poses a real challenge to rural development. The problems of semi‐subsistence farms are low cash incomes and incidence of poverty, sub‐optimal use of land and labour, a lack of capital and poor contribution to rural growth. However, they play an important welfare function in some rural areas in Europe; they manage more than 11 million ha of agricultural land and deliver ecosystem services. The Common Agricultural Policy will have to accommodate this now widespread production system, through existing or new policy packages. Particularly important is support for commercialisation to incentivise and smooth the transition to commercial agriculture, and agri‐environmental payments to compensate the semi‐subsistence farmers for the provision of ecosystem services.
