创业板与中小企业板上市公司财务状况比较研究——基于中小企业融资的视角 总被引：1，自引：0，他引：1
在比较分析国际创业板的市场定位与融资功能的基础上,选择我国创业板28家首批上市公司的2009年财务数据,并以相应的所属行业与会计期间都相同的中小企业板上市公司作为配对样本,将传统会计比率指标和现金流量指标相结合来构建两板上市公司的财务状况评价指标体系。通过差异性、相关性和因子分析法计算各公司的财务状况综合得分,据此比较分析两板上市公司的财务状况。实证结果表明:目前我国创业板上市公司整体财务状况较为乐观,普遍具有高盈利性与高成长性特点,大多具备了在中小企业板上市的资格。这说明创业板市场没有完全发挥好为成长潜力巨大的中小企业提供融资平台的功能,对其原因进行了探讨,并据此提出了规范与完善创业板的发展战略及政策建议。 相似文献

为了研究我国创业板上市公司的成长性,利用2011年之前在我国创业板上市的40家信息技术类公司的年报数据进行实证分析,发现我国创业板信息技术类公司可持续增长能力与销售净利率、总资产周转率、权益乘数和留存收益率高度正相关,与总资产自然对数的相关性不太显著。要提高可持续增长能力,应提高盈利能力、完善股利分配政策、适当利用负债融资、提高总资产营运能力。 相似文献

创业板市场设立目的在于促进自主创新企业及成长型创业企业的发展,然而,由于创业板证券市场上市条件相对宽松,上市公司质量更难以保证,而且上市公司自身的风险也相对较大;创业板市场信息不对称程度更高,易产生市场操纵和内幕交易等问题,市场风险大于传统证券市场,创业板上市公司的治理风险也不容小觑.我国创业板市场已经明确提出监管必须以信息披露为本,这就决定了创业板上市公司信息披露在创业板运行机制中的重要地位.本文针对创业板上市公司信息披露中存在的问题,分析其产生的原因,在我国创业板市场和上市公司的现实条件基础上,提出了从企业内外部监管和法律法规等角度来完善创业板上市公司信息披露制度的建议. 相似文献

把高管持股对公司价值的影响这一问题的研究范围集中到创业板市场,得出了与其他学者不尽相同的结论。研究发现,创业板的公司治理结构和股权结构与主板和中小企业板有明显差异,这是我国创业板上市公司高管持股对公司价值影响的"效应区间"不同于其他研究结论的重要原因。分别以标准化的市场价值和净资产收益率作为公司价值的衡量指标,通过对2010年和2011年创业板上市公司样本的实证分析,发现高管持股的利益趋同效应与壕沟防御效应同时存在于上市公司中,高管持股比例低于20%或高于50%时,利益趋同效应大于壕沟防御效应,高管持股比例在20%—50%时,壕沟防御效应大于利益趋同效应。 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

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
