地域特点、政策构建和创业激励具有内在的关联。长株潭自主创新示范区高层次人才股权激励政策在适用企业及激励对象范围、激励方式和条件、激励方案的拟定流程和国内其他国家自主创新示范区大体相似,但是在母公司负责人可参与子公司股权激励、奖励股份来源及限额、土地转让增值利润不纳入净资产增值额、知识产权和科技成果作价入股方面有了政策的新突破。长株潭高层次人才股权激励政策实施方面还存在高新技术企业认定滞后、已实施股权激励企业数量少、激励有效期限较短、激励对象覆盖面小、激励指标不合理等问题。为此,须从高新技术企业认定、调整激励幅度、激励考核标准的确定、设定激励期限、明确激励对象、设立股权激励专项资金、强化股权激励监督入手改进相关政策。 相似文献

随着我国研发创新政策的不断推进,企业越来越多增加研发投入,但是反映企业自主创新转化能力的研发资本化却没有随之改善.以A股市场2007—2018年上市公司数据为样本,从管理防御视角出发,研究经理人对企业研发创新投资的影响,以及股权激励能否发挥对经理人管理防御和研发投资决策之间的治理作用.结果显示:经理人管理防御显著正向影响研发投入却显著负向影响研发资本化,即经理人的研发创新投资决策具有一定的创新迎合倾向;股权激励负向调节经理人管理防御与企业研发创新投资之间的关系,证实股权激励对经理人进行企业研发创新投资决策的治理效果.最后从政府研发创新政策制订、企业研发创新信息披露和采取有效的股权激励措施等方面提出优化企业研发投资决策建议. 相似文献

本文以企业非效率投资值量化高管寻租水平,研究了股权激励对现金股利政策稳定性的影响,并探析了非效率投资在股权激励影响股利政策稳定性中的作用机制。基于代理成本理论、股利信号理论,结合我国股利政策研究现状,将股东普遍关注的现金股利政策稳定性作为股权激励效果评价的参数,选取2006—2015年A股上市公司数据,利用自由模型非参数法测定股利政策稳定性水平,借助残差分析法测算非效率投资水平,通过面板回归和层次分析法得出了以下结论：（1）股权激励后非效率投资水平增强且股利政策稳定性下降,因而股权激励不一定会发挥正效应;（2）非效率投资水平与股利政策稳定性负相关,即低效率投资减少企业自由现金流量,进而导致企业股利政策波动增强;（3）非效率投资在股权激励对股利政策稳定性的影响中,并非起到“中介作用”,而是遮掩了股权激励后股利政策稳定性的下降程度,成了高管寻租时的一个面具。论文据此提出以下对策建议：(1)客观看待股利平稳性指标,完善股权激励效果评价指标体系;(2)建立健全企业投资效率监督体系,长短期监控相结合;(3)优化上市公司股权激励方案设计,动态调整期权与股票授予比例。 相似文献

随着互联网经济的快速发展,互联网企业对人才的竞争也愈发激烈,股权激励作为我国上市公司激励、挽留人才的常用工具,也被广泛应用在互联网企业中.从股权激励要素特征的角度出发,对《中国互联网企业100强》中在2006—2020年实施过股权激励计划的25家互联网企业实施的65项股权激励计划进行分析.研究发现:目前我国互联网企业在实施股权激励时主要以股票期权和限制性股票两种模式为主,激励对象更倾向于核心技术及业务人员,激励额度整体偏小;同时股权激励计划在行权条件和激励期限的设计上偏向于"福利型",存在多期股权激励计划同时实施的现象,并从股权激励的方案设计角度提出建议. 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

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

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
