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

Prior literature focuses on the direct influence of entrepreneur’s creativity on firm-level innovation performance, but it ignores the intermediate mechanism of how. This study examines the role of bricolage in mediating the relationship between entrepreneur’s creativity and innovation performance. We propose that in SMEs, entrepreneur’s creativity can facilitate bricolage, which in turn influences innovation performance. Furthermore, the extent to which entrepreneur’s creativity can influence bricolage depends on firm age. Survey data from 249 SMEs indicate that bricolage functions as a mediator in the relationship between entrepreneur’s creativity and innovation performance. Entrepreneur’s creativity has a stronger effect on bricolage for young firms than for old firms. 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

This study compares the size and nature of the gender earnings differentials for the self-employed and wage earners in Korea, taking into account the workers’ self-selection of each employment type. The two-stage estimates of the earnings equation, corrected for worker selectivity, are used to decompose the gender earnings differentials into productivity-related and discriminatory factors. Our results suggest that the size of the gender earnings gap is larger in the wage sector than in the self-employment sector, but not by large margin, and so is the discrimination effect when not controlled for worker selectivity. With worker selectivity controlled, the discrimination effect is greatly intensified in the wage sector, while it becomes not significant in the self-employment sector. These findings imply that the observed gender earnings gap in the wage sector is largely ascribed to discrimination against women, while the gender earnings gap in the self-employment sector is mostly due to productivity difference that, in part, is caused by worker selectivity. 相似文献

出口退税作为一项贸易调控政策,在一国政府应对国际贸易的大幅波动中发挥着重要作用.文章以企业出口关系持续性作为研究切入点,结合高度细化的出口退税率数据,运用生存分析模型对出口退税政策的实施效果进行系统评估.研究表明:(1)总体而言,出口退税率的变动在短期和长期均对企业出口关系的稳定性产生了显著影响.(2)在短期内,出口退税政策的调整对企业出口持续性的影响不因其所在区域和行业特征的差异而存在显著不同,但在所有制属性层面,民营企业受到的影响程度最大.(3)在长期内,来自东部地区、民营以及低技术行业的企业不仅受政策变动的作用时效更长,而且受政策调整的影响效果也更明显;而来自西部地区、三资以及高技术行业的企业则对出口退税政策调整的反应敏感程度最低.因此,出口退税政策的实施需要结合出口信贷等政策加以综合运用,以保证经济的平稳运行. 相似文献
