中国六个典型城市休闲能耗的调研与分析

休闲能耗是城市消费领域能耗的重要组成部分,增长趋势很快。为了揭示个人生活模式对休闲能耗的影响,本文将休闲活动分为6大类19项。通过对各项休闲活动时间和频次的入户调查,根据城市各类休闲建筑与场所能耗强度、面积和城市市区人口的模拟计算、统计与调研,将发生在建筑与场所中的能耗分摊到进行休闲活动的人。在此基础上,分析了城市个人休闲能耗的分布情况,比较了各类休闲活动的能耗状况,论述了性别、年龄、学历、职业、收入、生活满意度等因素对休闲能耗的影响。

创新政策对我国制造业转型升级的影响——基于政策组合的政策文本研究

创新政策是推动我国制造业转型升级的重要驱动力,在对创新体系和政策组合理论回顾的基础上,使用政策文本量化分析和质性文本分析法,对我国制造业创新政策动态变迁及其对相关创新活动的影响进行研究。结果表明:我国制造业创新政策主体集中度较高、政策主体分布较为广泛、政策发布数量波动较大;环境面政策组合使用最为频繁、需求面政策组合使用最少、总体上对政策组合的使用呈现出"先扬后抑"的倒U型形态;制造业创新体系中4类创新活动强度差异较大;不同政策组合对创新活动的影响差异较大。最后,针对如何利用创新政策推动我国制造业创新变革提出相关对策建议。     

When in Rome,be(come) a Roman? An actor focus on identities in networks

Although the actor category in the Actor–Resource–Activity (ARA) model is less developed than its resource and activity dimensions, both activity links and resource ties ultimately depend on this category. The actor dimension is also central for identity research, but the fact that the actor is often conflated with activities may confuse our understanding of business interactions. The present study builds on the ‘organizational identities in networks’ approach, which offers an explicit actor focus. The study uses a longitudinal narrative case study that focuses on the development of a subsidiary in a multinational corporation to illustrate the complementarities between this approach and the traditional view of identity industrial networks. The paper contributes with a conceptual framework that emphasizes actor feature–activity links and the interplay between a focal firm's identity control and influences from other actors.     

知识经济、创新与价值工程

知识经济,是世界经济发展不可改变的趋向。世界银行１９９８年的世界发展报告《推动发展的知识》（ＫｎｏｗｌｅｄｇｅｆｏｒＤｅｖｅｌｏｐｍｅｎｔ）认为：知识经济给发展中国家所带来的挑战与机遇是：“要么搭上车,要么更落伍”。中国是发展中国家,应当怎样面对这个...     

老年人口日常生活自理能力城乡差异研究——基于CLHLS(2014)数据的实证分析

利用中国老年健康影响因素跟踪调查2014年数据,基于城乡差异的视角,运用二元Logistic回归剖析我国老年人口日常生活自理能力的现状及其影响因素。研究结果表明,我国城乡老人日常生活自理能力差异明显,影响因素也不尽相同,亟待全生命周期健康管理。在对高龄、孤独、视力不佳老人群体的普适性健康干预的基础上,城镇还需要多渠道维护贫困和独居老年群体的健康权益,农村则重在提倡定期体检、戒烟限酒、适度体力劳动的健康行为习惯,并加大对女性、无配偶、患有慢性非传染性疾病以及非独居老人的保障力度。     

Overtourism,optimisation, and destination performance indicators: a case study of activities in Fjord Norway

Abstract

Many global tourist destinations have experienced growth in arrivals. This has triggered various conflicts in destinations and sparked debates as to how to deal with what is increasingly referred to as ‘overtourism’. Most Destination Marketing Organisations (DMOs) pursue strategies to stimulate arrivals even further. Pro-growth discourses are reinforced by lead bodies such as the World Tourism Organisation (UNWTO). However, maximisation strategies based on higher numbers of tourists increasingly cause conflicts with local residents, whereas simultaneously undermining climate change mitigation pledges as negotiated in the Paris Agreement. New approaches to destination management based on optimisation are therefore warranted. Drawing on a survey of international tourists (n?=?5,249) in south-western Norway, this article discusses whether ‘activities’, i.e. the development of local, small-scale and ideally more sustainable experiences, can contribute to economic growth without necessarily increasing numbers of arrivals. Results confirm that destinations should seek to better understand their markets, including length of stay, spending, and/or activity intention, to identify profitable markets. Ultimately, such knowledge may help addressing overtourism conflicts while building tourism systems that are more economically, socially, and environmentally resilient.     

基于网络结构分解视角的区域R&D活动效率评价

基于网络结构分解的视角,通过构建不同假设条件(CRS/VRS)下的关联网络DEA模型,对我国区域R&D活动效率进行了评价和分析。结果表明:我国的区域R&D活动效率,无论是技术效率还是纯技术效率,都普遍偏低,而且存在明显的省际差异;经济转化过程并不是R&D活动效率普遍偏低的主要影响因素;科技研发过程与经济转化过程之间不仅缺乏必要的联系,而且存在显著的不协调性;相对于技术效率和纯技术效率而言,较高的规模效率并没有导致区域R&D活动效率的过度低下;东、中、西部三大地区的R&D活动效率不仅存在显著的地区差异,而且其内部差异也非常显著。
