The purpose of this study is to investigate the impacts of comparative claims across search and experience product types. Data was obtained from 159 Taiwanese college students. Results reveal that comparative claims used in blogs (compared to those in print ads) produce lower counterarguments and consumers more easily accept claims made on a blog. Comparative claims lead to higher brand attitude and purchase intention for search products on the blog; however, noncomparative ads lead to higher brand attitude and purchase intention for experience products on the blog. For both search and experience products, there is no significant difference. 相似文献

Anticipation may be seen as structured by images and representations, an approach that has informed recent work in science and technology studies on the sociology of expectations. But anticipation, as a capacity or characteristic, is not solely manifested in the form of representations, even where such representations of the ‘not yet’ are performative in nature. It also comprises material capacities, technological, biophysical and affective in nature. The politics of anticipation is shaped by how these symbolic and material capacities, and the forms of agency they make possible, are distributed. As anticipation is an environmentally distributed capacity, it is suggested that the politics of anticipation is also an environmental politics. A conceptual framework for analysing anticipation as comprised of environmental capabilities is introduced, and fleshed out using a case study of energy infrastructure planning from the UK. Key elements of this framework include the concepts of anticipatory assemblages and future horizons or ‘styles’ of anticipation. Working through the case study as an empirical example of a conflict concerning the politics of anticipation and of ‘environments’, it is demonstrated how the relationships between styles of anticipation are materially constitutive of such conflicts. 相似文献

运用2011-2016年中国内地31个省份面板数据,通过固定效应模型检验不同融资渠道对全国以及东中西部地区技术创新的影响。结果表明:①债权融资在整体上对技术创新影响不显著,分地区看,其在东部地区发挥了促进作用,而在中西部地区则起到抑制作用;②从整体及中西部地区看,股权融资对技术创新的影响不显著,且抑制了东部地区技术创新;③对股市板块进行细分后,整体上股权融资中只有创业板股权融资显著促进了技术创新水平提升,主板和中小板的作用均不显著。 相似文献

Previous research on whether the market responds to auditors’ opinions has provided mixed results. We revisit this issue in China, where individual investors who are more likely to neglect value-relevant information dominate the stock market. In addition to going concern opinions (GCOs), China permits modified audit opinions (MAOs) on violations of accounting standards or disclosure rules (GAAP/DISC MAOs), providing an opportunity not available in the literature to enrich the study of audit-opinion pricing. We find that, ceteris paribus, MAO recipients underperform in the future and have a higher incidence of adverse outcomes such as misreporting and stock delisting, and the market reacts negatively to MAOs during the short window around MAO disclosure. Importantly, MAO disclosure is not followed by negative long-term stock returns, suggesting stock price adjustments to MAOs are speedy and unbiased. These findings hold for both GCOs and GAAP/DISC MAOs. Together, our findings support the informativeness of audit opinions and cast doubt on the argument that investors inefficiently price audit opinions due to information-processing bias. 相似文献

This paper investigates the reasons why some technologies, defying general expectations and the established models of technological change, may not disappear from the market after having been displaced from their once-dominant status. Our point of departure is that the established models of technological change are not suitable to explain this as they predominantly focus on technological dominance, giving attention to the technologies that display highest performance levels and gain greatest market share. And yet, technological landscapes are rife with technological designs that do not fulfil these conditions. Using the LP record as an empirical case, we propose that the central mechanism at play in the continuing market presence of once-dominant technologies is the recasting of their technological features from the functional-utilitarian to the aesthetic realm, with an additional element concerning communal interaction among users. The findings that emerge from our quantitative textual analysis of over 200,000 posts on a prominent online LP-related discussion forum (between 2002 and 2010) also suggest that the post-dominance technology adopters and users appear to share many key characteristics with the earliest adopters of new technologies, rather than with late-stage adopters which precede them. 相似文献
