油气资源开发对中国西部区域经济的拉动效应分析——以陕西省为例 总被引：16，自引：0，他引：16
西部地区是我国油气资源储量最丰富的地区之一,但富集的油气资源没有推动西部区域经济的快速发展,西部地区人均国民生产总值长期居于全国中下水平,如何将油气资源开发与区域经济发展有机地结合起来,是我国西部地区经济发展实践中一个亟待解决的课题。本文以全国油气资源富集省份—陕西省为例,通过对油气资源开发活动所产生的投入产出效应、产业关联效应和收入分配效应进行实证研究,探讨了油气资源开发对区域经济发展的拉动效应,分析了西部地区油气资源开发活动与当地经济发展脱节的问题,并在此基础上提出了改进西部油气资源开发产业布局、完善油气资源开发产业链条以规避“资源诅咒”困境的政策建议。 相似文献

海洋经济的发展与海洋产业的发展高度统一,结合国外海洋产业发展的成功案例,在剖析浙江省海洋产业结构以及海洋经济投融资现状的基础上,以不同海洋产业为切入点,分析海洋传统产业、海洋新兴产业和未来海洋产业的投融资方式偏好,结果表明政府财政拨款是海洋产业重要融资来源,海洋渔业、造船业等传统产业以银行信贷融资方式最优,油气开采、生物制药等新兴产业和未来海洋产业更偏好股权融资和风险投资,且需要政策性银行和专业化海洋银行的资金支持. 相似文献

“海水对金属的腐蚀极其严重,制约了海洋开发事业和海洋产业的发展。海洋腐蚀环境的研究是一门边缘学科,也是海洋科学研究的重要领域之一。”这是全国优秀科技工作者、中科院海洋研究所研究员侯保荣博士强调的。 随着人口剧增,资源匮乏和环境恶化,人们越来越深刻地认识到海洋是人类生命的源泉、资源宝库和环境调节器。为此,全球共识21世纪将进入海洋开发的新时代。海洋开发的规模将不断扩大,海洋产业,包括临海工业、海洋大通道工程、海滨旅游业及运输业,特别是石油开发所建造的海上固定石油平台、海底油气输送管线等将成倍增加。 相似文献

我国海洋资源的合理开发与保护 总被引：2，自引：0，他引：2
海洋资源开发利用是我国海洋强国建设的重要内容,也是我国海洋经济的重要支柱。目前我国海洋资源开发利用主要是在近海,在经济飞速发展的大环境下,如何将海洋资源开发利用与海洋生态文明建设协同发展是我们必须面对的问题。资源的开发利用对环境产生了重要的影响,同时环境的恶化也对资源的开发产生了不利的影响,特别是海洋生物资源的发展更是如此。在近海很多区域我们过多地强调了海洋开发利用而忽视了海洋环境和海洋生态系统的保护,导致海洋环境恶化、海洋灾害频发,海洋资源可持续利用面临严重挑战,前景堪忧。因此,我们必须加强远离岸边的生物资源开发利用相关技术的研发,到深海大洋寻求更多的资源,同时解决资源开发利用中的环境保护问题,海洋开发利用与环境保护同时并举,建立基于生态系统的海洋资源开发模式,从海洋资源可持续利用的角度解决相关的科技支撑问题,实现综合管控海洋的目标 。 相似文献

深水油气是当今海洋油气勘探的主要热点 总被引：12，自引：0，他引：12
海洋是巨大的资源宝库。就地质矿产而言,海洋中蕴藏着丰富的石油、天然气和天然气水合物等能源资源；洋底的多金属结核、海山区的富钴结壳、磷块岩和深海多金属软泥,以及洋中脊的硫化物矿床等矿产资源。1992年第二届世界环境与发展大会,通过了《里约环境与发展宣言》将海洋列为可持续发展的重点领域。工业革命以来,矿产资源是支撑经济发展的重要基础。石油和天然气作为不可再生资源已经历了100多年的开发,终将枯竭。据专家估计,美国到2050年其石油资源将枯竭,我国由于油气勘探起步较晚,有相当一部分盆地的油气勘探程度较低,因此石油资源枯竭的时间将会推迟。海洋油气勘探需要高新技术的支撑,因此海洋油气勘探晚于陆地近一个世纪,而深海的油气勘探又晚于浅海近30年。由于篇幅所限本文主要对墨西哥湾、南大西洋和我国南海的深水油气勘探作一简介。 相似文献

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said. 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

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

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

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

This essay focuses on universal service and the Internet as means to support social and political participation. The emphasis on access to telecommunications systems in conventional approaches to universal service is contrasted with access to content. A model of the information environment is described that accounts for the roles of content and conduit, both of which are necessary conditions to achieve true access. A method is outlined for employing information indicators to observe or measure the information environment. 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
