环境规制、技术创新对全要素碳生产率的影响研究——基于中国省域的空间面板数据分析     

郭卫香  孙慧 《科技管理研究》2020,40(23):239-247

为探究环境规制政策是否能够实现碳减排和经济增长的“双红利”,本研究采用松弛模型的方向距离函数(SBM-DDF)模型和空间面板计量方法,通过测算2006-2016年中国省域全要素碳生产率,刻画中国省域全要素碳生产率的空间特征,进一步厘清环境规制、技术创新对全要素碳生产率的影响机理。研究结果显示：(1)中国各省份全要素碳生产率存在显著的空间集聚特征,其中高-高集聚(H-H)省份多位于东部沿海发达地区,而低-低集聚(L-L)省份多位中西部欠发达地区;(2)环境规制会促进全要素碳生产率的提升,且环境规制对全要素碳生产率的“本地效应”大于“邻地效应”;(3)技术创新在环境规制对全要素碳生产率的影响中存在部分中介效应。  相似文献   

农业科技成果转化效率测度及分析     

肖娴  毛世平  孙传范  胡小鹿 《中国科技论坛》2015,(8)

本文以2009—2013年农业科技成果转化资金项目作为研究样本,运用主成分分析法和DEA方法来测度中国现阶段农业科技成果的转化效率;在此基础上,从技术领域、转化主体和技术类型三个角度对农业科技成果转化效率进行比较分析。研究结果表明:现阶段中国农业科技成果转化效率整体水平偏低且年际增长趋势较弱;相对于其他类型转化主体,事业型研究单位农业科技成果转化效率最高且呈现出稳步增长的态势;模仿创新类型的农业科技成果转化效率最高,却呈现逐渐降低的趋势。  相似文献   

“懒惰”对人类科技进步的影响     

陈浩 《科学与管理》2015,(3):54-57

人类的"懒惰"表现为更舒适、便捷、低劳动强度的生活追求,从社会意识和个人意识两个层面推动科技进步。然而,这种影响是相对的、辩证的,懒惰是科技进步的动力之一,但科技进步反过来对人自身的影响也是双面的,可能会加剧人性中已有的懒惰因素(消极的懒惰)。应激发"懒惰"的积极因素,抑制"懒惰"的消极因素(追求不劳而获)。  相似文献

黄伟红  陈圣权  吴介一 《东南大学学报》1999,(2)

传统的单元式空调机都是本地控制运行的，但是现代信息技术的发展，要求单元式空调机能支持更多的功能．作为发展中的第一步，我们实现了一个基于制造报文规范的单元式空调机远程控制系统．制造报文规范是一个专为实设备的远程控制和监视而设计的ＯＳＩ应用层协议，它提供了操作人员在远程对单元式空调机的正常操作的功能．本系统（ 简称ＵＭＣＳ） 的实现使得制造报文规范的应用和单元式空调机的控制技术有了一个新的飞跃．  相似文献   

Search tactics used in solving everyday how-to technical tasks: Repertoire,selection and tenacity     

Sophie Rutter  Verena Blinzler  Chaoyu Ye  Max L. Wilson  Michael D. Twidale 《Information processing & management》2019,56(3):919-938

With greater access to computational resources, people use search to address many everyday challenges in their lives, including solving technology problems. Although there are now many useful ‘how-to’ resources online (especially videos on YouTube), it can still be difficult to identify, understand, and resolve certain kinds of technical problem. While research tasks have been studied for many years and we know the tactics people use, we know far less about searchers’ tactics for how-to technical tasks that involve actually being able to apply found information to resolve a problem. Crucial to our study was developing and studying a highly realistic, how-to technical task, for which there was no single guidance resource: making a phone safe for a child. After providing 39 participants with an actual phone to fix, and a search engine to perform the task, we analysed their search tactics using retrospective cued think aloud interviews. Our primary contribution is a set of 77 tactics used, in three categories, along with detail of how common they were. We conclude that people had a lot of tactics in their repertoire. Although it was not hard for participants to find relevant information, what was hard was for participants to find information they could use; indeed only 23% of participants successfully completed the entire task. Domain knowledge affected the choice of tactics used (although not necessarily towards better task success). We discuss these influences and make design recommendations for how future search systems can support those in resolving how-to technical tasks.  相似文献   

区域间专利引证关系特征及影响因素研究——以纳米领域为例     

武玉英  张婷婷  何喜军  蒋国瑞 《科技管理研究》2018,(3):198-204

区域间专利引证对技术知识的跨区域流动与共享具有重要作用。以纳米领域为例,收集2011—2015年专利引证数据,剖析全国31个省份间专利引证关系并进行分类,构建区域间引证关系的影响指标,利用泊松和负二项模型进行回归与检验。得出:高被引、高引证、双高地区均集中在北上广苏等区域,引证密度快速增加;引证量与自引率持续增高,被引量下降,说明纳米领域专利技术的区域辐射效果较弱,区域间专利引证不活跃;回归分析发现区域R&D经费、科技覆盖范围、h指数与区域间专利引证存在正相关。综上所述,给出了提升中国区域间专利技术引证的对策建议。  相似文献   

Bringing Cinderella to the ball: constructing a federal system of technical and further education in Australia, 1971–1975     

Peter Rushbrook 《Journal of educational administration and history》2010,42(1):33-54

Australian vocational education has a history dating from the late eighteenth century. As Australian colonies and, later, federated states evolved each constructed its own version of vocational education provision. Generally the systems, consisting of community‐based or state‐controlled colleges for the training of operatives, apprenticeships and professional support personnel, were poorly resourced and lacked powerful sponsors to support and promote the education and training of their mostly working‐class students. By the early 1970s Australian governments had developed commissions to supplement the funding of state‐based elementary, secondary and university education systems, even though under the Australian Constitution education remained state‐controlled matter. A reformist federal Labor government at the time consolidated elementary, secondary and university funding but neglected to consider, or even acknowledge, the 400,000 vocational education students not covered by these commissions. Following pressure from vocational education teacher unions, among others, the Labor government established the Australian Committee for Technical and Further Education (ACOTAFE) to address the needs of these students. At ACOTAFE’s first meeting on 25 March 1973, the Minister for Education Kim E. Beazley said, ‘It will be a renaissance in education when technical and further education cease to be Cinderellas in education. It is the role of your committee to bring Cinderella to her rightful role as princess’. ACOTAFE was to be chaired by Myer Kangan from the Department of Labour and National Service. The committee’s published outcomes were referred to evermore as the iconic ‘Kangan Report’ rather than TAFE in Australia: Report on Needs in Technical and Further Education, its formal title. The report gave Australian vocational education a name (TAFE), a philosophy (access to all through lifelong learning) and much needed capital works and infrastructure funding. The paper will outline the circumstances leading to the formation of the committee, its work and its outcomes. Focus will be placed on the influential role of Chairman Kangan in shaping ACOTAFE’s conclusions. A key theme within the paper is the intersection of biography, politics and the economy in shaping policy construction.  相似文献   

国家职业标准对高职院校教学改革的指导与实践   总被引：1，自引：0，他引：1  

赵继忠 《鞍山师范学院学报》2010,12(5):104-106

高职院校面向企业培养学生的＂职业能力＂,不同于普通高校人才培养目标,因此在教学计划、课程体系中要摆脱普通高校的影子,有必要对其教学体系进行改革。国家职业标准作为劳动技能的衡量准则,能够指导从业人员在某一特殊领域掌握比较熟练的操作技能。将国家职业标准引入教学体系中去,可以将企业前移到大学,使得高职院校培养的学生与企业用人做到无缝连接。  相似文献
