人力资源是资源型城市经济转型中替代自然资源促进经济增长的重要要素.资源型城市人力资源存在着数量充裕与质量较低的矛盾,需要进一步加大人力资本投资力度.针对员工个人、资源型企业和资源型政府在人力投资收益中的不同价值取向,设计了投资导向型、利益导向型、外部导向型和双高平衡型的投资分享机制,并在资源型城市经济转型的技能培训政策中进行了应用. 相似文献

资源型城市在中国国民经济发展过程中扮演着重要角色,为国家经济建设提供了大量自然资源。然而随着自然资源的过度开采,资源型城市面临着资源耗尽和环境污染等问题,资源型城市要实现可持续发展,必须进行低碳转型升级。基于此本文首先阐释了资源型城市低碳转型的影响制约因素,构建了低碳转型评价的指标体系,并对转型等级进行了划分,在此基础上确定了考虑非期望产出的SBM评价模型,以17个典型资源型城市为例,通过ML指数及TFP分解值在不同年度的差异化变动进行了实证评价,以检验评价系统的科学性和可行性。 相似文献

【目的】领导干部自然资源资产离任审计是加强中国生态文明建设的一项重要制度安排，从中国特有的政治经济社会背景出发，探求其改善环境质量的作用机理和经验证据具有重要意义。【方法】以2015—2020年中国303个地级及以上城市为研究对象，按照自然资源禀赋的异质性，将资源型城市作为处理组，非资源型城市作为对照组，采用双重差分模型考察领导干部自然资源资产离任审计在全国推广期间的政策效果。【结果】(1)伴随着自然资源资产离任审计制度的常态化，相对于非资源型城市，资源型城市的环境质量得到明显提升，具体表现为工业污染的减排。(2)机制检验的结果表明，资源接续压力和环境绩效压力对资源型城市环境质量的改善具有促进作用，离任获得晋升的地方官员在任期内拥有更好的环境表现，支持了该项政策通过完善政绩考核和责任追究机制推动污染治理的理论逻辑。(3)路径检验的结果表明，环保投资的增加是促进资源型城市环境质量提升的可能路径。【结论】自然资源资产离任审计制度符合中国国情，具有长效性和普适性，应加强审计结果运用、完善配套制度建设，推进环境责任审计的全覆盖。 相似文献

资源型城市为国家经济建设提供了大量自然资源,面临着资源耗尽和环境污染等问题,必须进行低碳转型升级以实现可持续发展。为此,首先阐释资源型城市低碳转型的影响制约因素,构建资源型城市低碳转型评价指标体系,并对转型等级进行划分;在此基础上,确定考虑非期望产出的SBM评价模型,以国内17个典型资源型城市为例,通过生产率指数(ML)及全要素生产率(TFP)分解值在不同年度的差异化变动进行实证评价,以检验所构建的评价系统的科学性和可行性。实证评价结果表明,低碳技术进步和环境管制政策的双重作用能够促进资源型城市的低碳转型,两者效应的叠加使资金更多地向技术创新领域倾斜,并集中于低碳产业,这有效促进资源型城市低碳经济的增长。 相似文献

资源型城市长期以来对我国的经济发展做出了重要贡献,但是由于资源城市自身发展特点和我国经济体制改革的特殊历史背景,资源城市普遍面临着城市转型的问题。自然资源的不可再生性决定了资源城市转型的关键在于对人力资源的认识和开发。 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

Prof. SUN Changpu from the CAS Institute of Theoretical Physics coworkers from University of Basel in Switzerland have worked out a way - at least in theory - to split a beam of molecules according to their chirality. The technique involves passing the molecules through three different laser beams is similar to the famous Stern-Gerlach effect whereby a beam of atoms passing through a magnetic field is split in two according to the atoms' spin states 《中国科学院院刊(英文版)》2008,22(1):23-23
