"研发费加计扣除政策"是推动我国战略性新兴产业发展的财税优惠政策之一,有关"研发费加计扣除政策"的税收激励效应的评价和分析对提高财税政策激励精准性及进一步贯彻落实创新驱动发展战略具有重要价值。以2010—2016年我国战略性新兴产业上市公司为样本进行实证分析,创新性地运用熵权法从"减负"、"增效"和"促进研发"3个维度构建研发费加计扣除激励效应指数,通过构建逐步回归模型实证检验了"研发费加计扣除政策"对战略性新兴产业上市公司的税收激励效应。结果发现:"研发费加计扣除政策"对战略性新兴产业上市公司具有显著的税收激励效应;不同行业、不同创新主体和不同规模的上市公司的税收激励效应具有显著差异。进一步建议应确保"研发费加计扣除政策"的差异化,制定政策绩效评价制度,加大政策宣传及培训力度,提高政策激励的精准性及有效性。 相似文献

战略性新兴产业往往诞生于技术的突变性变化之中,其发展在技术、市场和组织等方面存在多重不确定性,需要政府的大力培育和引导。当前我国战略性新兴产业的相关政策呈现"碎片化""粘性化"现象,缺乏对战略性新兴产业的动态演变进行持续性跟踪和控制。在把握战略性新兴产业发展特征的基础上,政策主体应构建动态的产业政策调整机制以适应战略性新兴产业的演进发展。 相似文献

战略性新兴产业对于培育经济发展新动能、实现经济社会健康发展具有重要意义。以中央层面的通用航空产业政策文本为样本,从"政策工具-产业价值链"两个维度,采用政策文本分析法对政策条目进行量化分析,深入剖析我国通用航空产业政策中存在的政策工具使用不平衡、需求面政策工具缺失、产业价值链阶段政策不平衡等问题,并提出完善和优化我国通用航空产业政策的有关对策建议,包括适当降低供给面、环境面政策工具使用,兼顾需求面政策工具带动作用,以及重视政策工具在产业发展的全方位运用方面等,为完善我国战略性新兴产业相关政策提供参考。 相似文献

江苏省战略性新兴产业发展的金融支持研究——基于上市公司的实证分析 总被引：1，自引：0，他引：1
战略性新兴产业的培育与发展离不开金融业的支持。但由于战略性新兴产业的自身特性及其金融需求与传统融资模式之间存在着一定不匹配性,导致当下金融业在支持战略性新兴产业发展上仍存在一些问题。在分析江苏省战略性新兴产业金融支持现状基础上,以江苏省22家战略性新兴产业上市公司为例建立面板数据模型,通过实证分析发现:留存收益融资和商业信用融资对江苏省战略性新兴产业发展起正向支持作用;而银行信用融资和股权融资对江苏省战略性新兴产业发展起负向支持作用;债券融资对江苏省战略性新兴产业发展的作用则不显著。总之,金融对江苏省战略性新兴产业的支持作用尚未得到充分发挥,金融支持效率偏低。由此从政策性金融、银行信贷、资本市场以及风险投资等4个维度系统提出金融支持江苏省战略性新兴产业发展路径的政策建议。 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
