Analytically comparing disaster resilience across multiple dimensions

It is important to compare the resilience of complex human systems to different types of disasters, in order to assess their inherent vulnerabilities and take appropriate actions to strengthen them. Resilient behavior can be complicated and multi-dimensional, however, and one must be able to characterize the different ways in which that resilience actually exhibits itself in practice. With this in mind, this paper discusses creating a multi-dimensional indicator for the resilience of a complex human system, and it explores an approach for visualizing and analyzing the relationships between each of the individual resilience dimensions. Because decision makers may differ on the relative contribution of the different dimensions to overall resilience, the paper further discusses the issue of weighting the different dimension values and the impacts that such a weighting scheme can have on the relative ranking of different scenarios. We illustrate the ability to characterize the complexity of multi-dimensional resilience by analyzing an empirical data set that measures the relative resilience of the New York metropolitan area to seven different natural disasters between 2010 and 2012.     

UGC信息类型及发布者头像对其他用户购买意愿的影响 ——基于社会化电商小红书社区的研究

社会化电商社区包含着丰富的用户生成内容,通过用户生成内容的生成、分享和传播,影响用户的购买意愿。从小红书社区“带货”现象出发,以心理距离理论为视角,探究具有不同信息类型的用户生成内容对其他用户购买意愿的影响,并且研究拥有肖像类头像的发布者特征的调节作用。通过实验研究发现,在社会化电子商务社区中,体验型用户生成内容对其他用户购买意愿具有正向的影响,且用户感知心理距离产生中介作用,对于以肖像形象作为头像的发布者而言,这种影响更为显著。     

The influence of user-supplier relationship on innovation dynamics of Oil & Gas industry

ABSTRACT

This paper analyses the role of user-supplier relationships in the innovation dynamics of the Oil and Gas (O&G) industry, from an analysis supported by R&D and patent application data. This paper points to some recent interesting phenomena in the O&G sector, such as: (i) the remarkable advancement of two Chinese oil companies; (ii) the significant growth in O&G companies’ technological engagement in exploration and production (E&P) from the 2000s; (iii) the non-negligible increase in the application of O&G companies’ patents for renewable energy. Moreover, by working with the oil and gas chain complete, we show that the performance of the companies oil and gas equipment and services industry (O&GES) is restricted to the upstream activities. Finally, we bring up some arguments that have as objective relativise the typology of R&D intensity adopted by OECD.     

财政分权对全要素生产率的影响--基于“省直管县”改革的准自然实验

"省直管县"改革一改以往"省-市-县"的管理模式,有助于提高县级政府的财政分权水平。为缓解内生性,将"省直管县"改革视为一项准自然实验,构建双重差分模型检验了财政分权对全要素生产率的因果效应。研究发现:①财政分权对全要素生产率的正向促进作用高于负面阻碍作用,但不同形式的分权影响有异质性,具体来说财权的下放有利于全要素生产率的提高,经济社会事务管理权限的下放则不利于。②当地方政府自主权提高时,其"重生产、轻服务"的支出偏好,使得当地基础设施供给增加,而能够增强地方软实力、加快创新要素集聚的公共服务供给相应减少,造成了全要素生产率的损失,导致在经济高质量高效益增长中政府"有形之手"的作用发挥不够。③随着改革的推进,财政分权对全要素生产率的正向作用逐渐减弱,并不再显著。据此,从合理划分省以下政府的事权与支出责任,充实基层政府财力;提高公共服务类指标在政府官员政绩考核中的权重,加强各县(市)政府间的合作,实现各自为政的地方经济向统一市场整合等方面提出政策建议。     

虚拟品牌社区顾客体验会带来其价值共创行为吗--基于手机虚拟品牌社区的实证研究

本文以顾客体验为切入点,基于价值共创理论、心理所有权理论和互惠规范理论,并运用于S-O-R理论框架,构建了虚拟品牌社区下,顾客参与价值共创行为产生的影响路径模型,通过问卷调查与实证分析得出:第一,顾客信息体验和娱乐体验越强,其参与价值共创的意愿程度越高,心理所有权部分中介了二者的促进关系;互动体验强化了社区顾客的心理所有权,并经由心理所有权的完全中介提高其参与共创意愿。第二,顾客参与共创意愿程度越高,其价值共创行为就越容易出现,社区的互惠规范正向调节了二者的关系。     

全球视角下生态系统服务付费的国际经验与评价

将生态系统服务付费(PES)工具分为经济类和非经济类两种,根据生态服务生产者和付费者的支付意愿,进一步细分为双方自愿支付、集体自愿支付、强制双方支付、强制集体支付四种具体的PES制度,通过分类介绍PES机制在全球的各种实践案例,归纳PES机制成功推行的共同点,分析PES系统的社会和环境挑战与由此产生的生物多样性风险之间的关系。     

上海市大力发展农村金融服务的SWOT分析

运用SWOT方法对上海市大力发展农村金融服务进行分析。分析结果可知上海在大力发展农村金融服务时存在政策、地理位置优势;但在法律和农户金融意识方面存在劣势;此外,上海市既面临"互联网+"与金融合作、潜在需求大的机遇,也面临违约和诈骗风险的威胁。     

Services as drivers of economic growth. Is there an opportunity for Latin America countries?

ABSTRACT

Considering the recent improvements in services innovation and productivity performance, the aim of the article is to analyze if they can act as a new growth driver for Latin American countries. For that, we review the literature on services and structural change in two stages. First, we apply a bibliometric methodology to identify the main trends in literature. Second, we analyze in-depth a smaller set of papers in order to extract the main lessons regarding three aspects of our question: (i) services and productivity growth, (ii) new opportunities for innovation in services and (iii) relation between services and manufacturing through servitization process. The results show that productivity and innovation growth in services are concentrated in only a few branches. Besides this, services performance depends on their links with manufacturing activities. We conclude that the current Latin American servitization process clausure opportunities for developing instead of opening them.     

生产性服务业集聚与全球价值链地位攀升

结合中国工业企业数据和城市经济数据，运用工具变量回归从专业化和多样化层面探讨中国生产性服务业集聚对制造业全球价值链地位的影响。研究发现，从整体上看，不论是专业化还是多样化，生产性服务业集聚均能够显著提升中国制造业的全球价值链地位。分样本检验显示，生产性服务业集聚对全球价值链地位的提升作用主要存在于沿海省份、资本和技术密集型行业以及中小企业。在作用机制方面，生产性服务业专业化集聚主要通过提高创新水平和推动全要素生产率促进全球价值链地位的提升，而多样化集聚则通过加快要素流动和推动全要素生产率来提升全球价值链地位。
