伴随着服务经济时代的到来以及科技服务业的迅猛发展,科技服务业对制造业发展的推动作用越来越引起人们的关注,然而在我国关于科技服务业与制造业联动发展的研究较少。以中山市的数据为例对科技服务业与制造业之间的关系进行实证分析,通过协整分析和格兰杰检验发现中山市科技服务业与制造业之间存在着长期均衡关系,两者之间互为因果关系。研究结果为中山市产业结构转型升级提供政策依据和有益的借鉴。 相似文献

知识密集型服务业与制造业联动发展是现阶段关注的热点。选取知识密集型生产者服务业作为研究对象,根据我国1992—2012年信息服务业、科技服务业、金融服务业、商务服务业增加值及制造业历史数据,构建VAR模型,利用ADF检验、协整检验、Granger因果关系检验、脉冲响应及方差分解方法,探讨知识密集型生产者服务业与制造业间的联动发展状况。结果表明,知识密集型生产者服务业增加值与制造业增加值间存在长期稳定的协整关系;提升科技服务业与商务服务业水平是科学推动制造业发展的有效途径。针对研究结果,提出推动产业联动发展的相关建议。 相似文献

工业4.0时代,信息产业作为经济创新发展的支柱产业,对当下经济增长的贡献日益显著。探究信息产业对经济增长的影响具有重要现实意义。上海作为我国经济发展的重要城市,信息产业发展迅速。因此针对上海市信息产业结构,将信息产业主要分为信息制造业、信息销售业、信息服务业3大类,根据信息产业结构与经济增长发展现状,运用灰色关联度的分析方法,分析了上海市信息产业结构与经济增长之间的关系,结果表明信息产业和经济增长之间的关联度非常高,其中信息服务业与经济增长之间的关联度最大,其次运用协整检验和格兰杰因果检验,对1997—2016年上海市信息服务业产业总值和上海市生产总值进行实证研究。结果表明信息服务业对上海市经济增长具有一定的推动作用,但其互动机制作用不明显。最后从优化信息产业内部结构、注重发展现代信息服务业、促进信息服务业和信息制造业融合发展、以创新驱动信息制造业升级带动信息销售业发展等方面提出了相关建议。 相似文献

开放条件下山东省现代服务业科技发展问题探讨 总被引：1，自引：0，他引：1
现代服务业在国民 经济中的地位不断提高,国际贸易 和投资也逐渐向现代服务业倾斜。 山东省现代服务业总体来说发展较 慢,但其对山东经济如就业的贡献 日益增大,同其他省份相比,山东省 服务业包括现代服务业总量较大, 但发展力度不够。有鉴于此,本文从 提高现代服务业科技水平角度出发, 建议山东省服务业循序渐进开放, 加强与高新技术和信息产业的结合, 提高专业化分工水平等。 相似文献

在分析港口与城市经济互动发展系统结构和特征的基础上,构建了基于系统动力学(SD)的因果关系图,选取城市GDP、港口通过能力、港区占地面积、港口深水岸线长度作为状态变量,构建系统流图和系统动力学方程。以深圳市为例进行实证分析,通过对仿真模型结构和行为的检验,验证了模型的有效性。选取港口投资政策因子、岸线消耗系数、港区土地占用系数、港外土地占用系数以及表示港口业对航运服务业和港口物流业促进程度的乘数作为控制变量进行仿真,分析这些因素对港口与城市经济互动发展系统的影响。仿真结果表明,为实现深圳港口和城市2020年发展目标,需要适当的增加港口建设投资,但要避免码头重复建设带来的土地资源大量占用问题;集约利用港口土地资源,提高土地资源的利用效率;同时提升港口的物流和航运服务功能,以实现港口的转型升级。 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

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

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
