为促进种业技术创新效率提高,基于2013—2018年我国30个省份的种业企业数据,运用DEA-Malmquist模型对企业技术创新效率进行测算和动态分析,并运用面板Tobit模型和门限回归模型分析政府补贴与市场集中度对企业技术创新效率的影响.结果表明:我国种业企业技术创新效率整体偏低,全要素增长率提高主要依赖于技术进步和创新;市场集中度对企业技术创新效率具有负面影响;政府补贴可以促进企业技术创新效率的提高,但效果会受到市场集中度的调节,市场集中度过高会抑制政府补贴的积极效果.基于研究结论,提出加强市场和政府两种手段的协调和控制种业市场集中程度等促进我国种业产业高质量发展的对策建议. 相似文献

种业是我国战略性、基础性产业。近年来,虽然我国种业得到快速发展,但其生产经营中仍表现出"多、小、散、乱"现象。从世界种业发展历史来看,种业并购整合是种业产业升级和企业发展的重要途径。种业并购信息是种业并购整合的基础,如何科学地构建种业并购信息交流服务平台并进行合理评价,是我国种业界遇到的新问题。针对这一问题,本文运用层次分析法构建了平台评价指标体系,从资源情况、平台服务、运维管理和客户满意四方面进行分析评价,其结果是信息准确性、信息资源整合能力和信息全面性三因素排在前三位,信息被采纳率、人才队伍、创造价值排在倒数后三位。希望该结论可以为以后的平台建设给予参考,以推动种业并购信息交流服务平台的建设与管理。 相似文献

与企业依靠内部资本积累发展相比较,通过企业并购实现种业整合具有更强的推动力,而企业采取什么方法、什么时候、什么地点进行并购,不仅影响并购的实施,也决定并购的效果。本文根据种业企业并购整合特点,从投资收益、核心能力、并购成本和协同效应四个方面,建立评价我国种业企业决策三级指标体系,采用模糊层次分析法,多目标分层次求出最优最佳决策。研究结果表明低成本融资优势、种业市场占有率、产品和市场多样化、内部化优势以及分销渠道这五个因素,所占全部评价子项目的累计权重达到62%以上,可以代表总共十六个评价指标来评价种业企业并购决策体系的影响力,对种业企业并购决策有效实施也起着重要作用。 相似文献

A research 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 in red wine-can improve the sensitivity of mice to the hormone insulin according to a report in the October issue of Cell Metabolism.…… 《中国科学院院刊(英文版)》2008,22(1):14-15
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
