半导体产业技术密集程度高、创新链条长，因而研究我国半导体产业联盟的协同积极性问题需从更为广阔的产业生态链视角展开。以产业生态链理论为分析框架，从生产方、学研方和服务方角度构建半导体产业生态链三方演化博弈模型，探究影响产业生态链稳定发展的各项要素；同时，基于我国半导体上市企业2016－2021年我国半导体上市企业的面板数据对博弈模型进行仿真分析。研究发现：产业生态链的协同运作受各主体不同策略行为的共同作用，与协同收益相比，各方对成本的变化更敏感，且生产方与学研方积极合作意愿对配套服务企业策略选择的影响相对较大；成本和收益分配机制影响主体的参与意愿，且存在最优的收益分配系数使生产方与学研方采取协同策略的意愿最强；配套服务价值的增加虽然提高了产业协同收益，但难以促进各方积极合作；提高产业创新效益并约束主体行为是促进半导体产业生态链积极合作运行的关键。因此，需在以按劳分配为主体的同时，强化政府对于产业生态链的引导与支持，建立健全产业生态链利益分享机制。 相似文献

产业共性技术创新事关我国前沿产业的发展和国家经济核心竞争力。针对产业共性技术创新具有成本高、风险高、环境正外部性等基本特征,核心企业和中小企业的有限理性及其在资源禀赋方面存在的异质性,使得双方在创新合作过程中均存在博弈行为。本研究引入政府补贴、资源拥有量、碳价和资源交互系数等关键参数,构建了企业资源禀赋异质下的产业共性技术政产学研协同创新演化博弈模型,并采用演化相位图和数值模拟方法分析了各参数对于企业策略选择的影响,得到了产业共性技术协同创新演化博弈系统的演化特征及变化规律,提出了促进资源禀赋异质企业协同创新的建议与对策。 相似文献

通过将生产性服务业区分为创造型和保障型两种类型,并基于演化博弈理论,分别对战略性新兴产业与创造型生产性服务业的研发创新博弈,与保障型生产性服务业的外包创新博弈进行理论推演。通过构建产业创新系统协同度模型,采用2004-2012年的相关统计数据,对战略性新兴产业(以传统制造业为对比)与生产性服务业的协同创新状况进行了测度及分析。结果表明,提高参与协同创新的企业比例是提升战略性新兴产业与生产性服务业协同创新水平的重要途径,战略性新兴产业与创造型生产性服务业所进行的协同研发创新对于提升其协同度水平具有更大的促进作用。 相似文献

针对我国半导体产业形成的产业链企业,使用两阶段网络DEA测度产业链企业的创新效率,以产业链企业协同创新指标为核心解释变量构建回归模型,探究半导体产业链企业协同创新网络对企业创新效率的影响。结果表明：在半导体产业链企业当中,协同创新网络联结强度与企业创新效率负相关,协同创新网络联结强度对企业整体创新效率的正向影响还未发挥出来;产业链企业技术创新阶段效率低于产品创新阶段效率,且企业间联合专利申请数量偏少,产业链企业协同创新主动性偏低;产业链企业协同创新能够有效缓解高技术产业中技术知识外溢,保护创新企业先行优势;从创新两阶段来看,产业链企业协同创新网络联结强度分别与企业技术创新阶段效率、产品创新阶段效率呈倒U型、正U型关系。 相似文献

产业集群作为战略性新兴产业发展的主要模式,已成为各国学术界讨论的热点话题。我国处于供给侧结构改革、转变经济发展方式的重要时期,需要集中力量发展战略性新兴产业。本文建立以集群内企业和科研院所为博弈主体的双方演化博弈模型,通过稳定策略分析可知,确定合理的利益分配是各方保持协同治理的核心；同时加入一些奖励惩罚机制以及信息共享机制对各主体具有激励作用,政府的监管,则进一步优化对企业间的协同治理。 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

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

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

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
