大学生创业孵化园是集企业孵化、研发创新、人才培养为一体的服务平台,有利于引导和鼓励大学生自主创业,提高大学生创业能力。作为由民营资本投资,以科技型产业为引领、大学生创业为主的综合性和专业性创业孵化基地,赛博(杭州)创业工场的服务特色为“创业导师+天使投资+债权基金+风险担保+服务平台”,其迅速发展的同时不可避免地在发展定位、创业者能力、导师制对接、风险投资环境以及社会资本等方面存在问题。因此,有必要结合大学生创业孵化园实际,在发展定位、政策支持、创业能力、融资服务平台以及创业环境等方面下功夫,以促进大学生创业孵化园生态链的形成,保证大学生创业持续发展。 相似文献

共性技术因其在技术创新链条中的基础性地位和对相关产业集群创新的巨大拉动效应,受到各国政府的广泛重视,而产业共性技术创新必须依靠政府指导下、不同产业共同参与的“产学研”合作模式,运用两群体模仿者动态微分方程,分析了在不同情景下分别来自新兴产业和成熟产业的两类异质企业间与学研机构合作研发共性技术的演化博弈过程和稳定策略,并运用数值模拟对理论命题逐一进行仿真验证,最后得出结论与启示。 相似文献

Titles of online products play an important role in attracting consumers and promoting product sales in e-commerce. However, current online product titles only cover basic features and cannot reflect the preferences of consumers exactly. To address this problem, this research proposed an online title optimization method based on the analysis of online reviews, which is called TOOR (Title Optimization based on Online Reviews). In this research, we analyzed and compared product features extracted from online product titles and online reviews from the point of view of consumers and applied features extracted from reviews to title optimization. In order to verify the effectiveness of the proposed method, two experiments were conducted in this paper, selecting four typical smartphones as experiment samples and Taobao.com as the data resources. The experimental results indicated that features extracted from online reviews can better reflect the consumers’ concern, and the titles optimized by the TOOR method are more appealing to consumers and have higher click-through rates. 相似文献

This study assessed how and to what extent self-regulation of online behavioral advertising (OBA) is executed on participating companies' websites. Based on the principles of OBA, as outlined by the Digital Advertising Alliance and Federal Trade Commission, we analyzed the format of OBA notices, explanation of OBA notices, opt-out options, transparency, and use of unacceptable notices. A series of content analyses was done in the years 2013 and 2015. Our results indicated slight improvements over the years, but the specific details of the implementation continued to fall short of the standards. In terms of accessibility and visibility, many websites demonstrated problematic presentations or lack of the components necessary to increase consumers' understanding and control over the practice of OBA. 相似文献

This article studies the welfare effects of credit arrangements and how these effects depend on the trading mechanism and inflation. In a competitive market, credit arrangements can be welfare reducing, because high consumption by credit users drives up the price level, reducing consumption by money users who are subject to a binding liquidity constraint. By adopting an optimal trading mechanism, however, these welfare implications can be overturned. Both price discrimination and nonlinear pricing are essential features of an optimal mechanism. 相似文献

国内市场一体化将会对中国制造业的空间分布造成何种影响?本文通过构建统一的理论分析框架验证了国内市场一体化影响制造业集聚的两种机制:其一是贸易成本总体水平的调节效应,其二是贸易成本非对称性的直接效应,而调节效应的方向则取决于模型理论范式选择。此外,本文基于中国区域间投入产出数据,系统地测算了中国地区间的非对称双边贸易成本,并基于测算结果进行回归分析。实证结果表明,在中国制造业发展初期,市场结构总体符合IRS MC范式设定,此时贸易成本的调节效应倾向于促进制造业在东部沿海区域集聚。伴随着制造业生产技术的成熟,制造业市场结构开始呈现CRS PC范式特征,此时市场一体化对制造业集聚的调节效应不再显著。 相似文献

This article focuses on the role of teenagers’ anticipated labour force participation in explaining the upward trend in U.S. women’s college-going. A simple conceptual model implies that individuals with more anticipated lifetime hours of work are more likely to invest in college education. My analysis using data from three National Longitudinal Surveys supports the theoretical implication. This finding, combined with the trend towards higher work expectations of young women across birth cohorts, may account in part for the upward trends in women’s college attendance and completion. 相似文献

We investigate the financing decisions of Korean firms during the period of 1996–2015. Korean firms follow a matching strategy for funding their cash needs. Cash inflows from investing activities are the primary source of funding for capital expenditures, and cash inflows from financing activities are the major means of covering cash outflows from financing activities. We also find that Korean firms’ financing practice of handling cash deficits can be described by the pecking order model modified and augmented by cash flow variables. Cash inflows from investing activities account for the major portion of financing to make up for cash deficits, followed by short- and long-term debt, and then equity financing. 相似文献
