政府监管下产学研协同创新体系资源共享行为分析 总被引：3，自引：3，他引：0
基于有限理性和不完全信息假设,建立政府-企业-学研方的三方演化博弈模型,研究产学研协同创新体系中资源共享行为的内在决策机理。通过分析不同策略组合下的成本与收益情况,探寻影响双方资源共享的关键制约因素,给出不同条件下各参与主体的演化稳定策略,并利用三维立体图阐释策略演化路径规律。以此为基础,提出促进产学研协同创新资源共享的对策建议。 相似文献

应用有限理性假设下的演化博弈研究方法,引入额外收益分配系数、违约金的惩罚数额等因素构造产学研合作创新演化博弈模型并进行Matlab数值仿真模拟,判断策略的进化稳定性,分析产方和学研方的策略选择行为。研究结果表明:演化结果具有鲜明的路径依赖特征,取决于系统的初始状态,并与合作方从合作获得收益多少及收益能否得到公平分配和违约金的惩罚数额密切相关。因此,确定合理的违约金惩罚数额和分配系数的范围,才能保证产学研双方收敛于合作的稳定状态。 相似文献

采用以有限理性假设为前提的进化博弈理论作为分析工具,构建了科技保险险种创新进化博弈模型,进而对双方主体策略的进化稳定性进行了分析,并以C保险公司为例,通过构建系统动力学模型,运用虚拟数据进行了模拟计算。然后,基于对险种创新主体行为的分析,对险种创新促进策略进行了探讨。研究结果表明:保险公司选择开发新险种策略的基础是新险种所带来的超额收益;政府干预险种创新的基础是我国科技保险市场具有活力,且干预行为具有良好的社会效应;在博弈过程中,只要有一方主动选择积极策略,则另一方也会逐步向积极的方向发展。 相似文献

本文分析生态经济视角下政府环境监测部门与企业在污染治理过程中的博弈行为。首先分析完全信息静态博弈分析的纳什均衡,然后扩展到群体有限理性下博弈分析,建立了政府监管部门和企业在各自不同的策略选择时的成本和收益函数,运用演化博弈理论研究了博弈模型的稳定性策略。分析结果表明:政府部门应该对企业污染加大监管及惩罚力度;企业应该运用更高的科技水平来降低污染物的产生及污染治理成本;加大政府监管失职处罚,强化政府监管职责;完善环境监管机制,提高政府监管效率,减少监管部门对于企业的监管成本。 相似文献

在有限理性条件下,运用演化博弈方法对软件外包企业技术发展过程中,自主研发和技术合作的选择机制进行了分析,建立了技术发展策略选择的复制者动态模型,寻找其演化稳定策略。结果表明:当企业自主研发的技术收益大于技术合作的收益时,企业都会选择自主研发策略;当自主研发的技术收益小于技术合作的收益时,企业策略选择依赖于另一方选择策略的概率。在此基础上提出软件外包企业技术发展策略选择的建议。 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

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

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence 相似文献
