This paper investigates the relationship between environmental regulations and innovation by focusing on the automobile industry in a cross-country setting. We provide empirical evidence that the presence of agency problems mitigates the negative effects of environmental regulations on overall R&D activity, which leads to full compensation when the degree of agency problems is sufficiently high. Guiding our empirical analysis, we provide a general model consistent with the structure of existing ownership data. Specifically, we model ownership structure as a combination of two extreme corporate governance types. On the one extreme there are profit maximizers, and on the other extreme there are managers who are only concerned with their private benefits. The model leads to a simple country level ownership indicator and shows that if an economy is dominated by firms with higher agency problems, then pollution tax might even increase overall R&D, while reducing pollution. According to our estimations, such an outcome is possible only for out-of-sample values of the ownership indicator, where the degree of agency problems is extremely high.  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

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

员工谏言不仅具有建设性,而且具有挑战性和结果的不确定性,使得领导者可能纳谏也可能拒谏。然而,现有研究主要关注员工谏言与领导纳谏,却忽略了领导拒谏。本研究在回顾员工谏言及相关研究的基础上发现,领导者会对员工谏言进行建设性评估和威胁性评估,具有建设性和防御性两种行为目的。基于此,首先,从领导者的双元行为目的出发探讨了领导拒谏的概念与维度,依据发展视角、人际视角和防御视角将领导拒谏划分为:指导员工驱动的拒谏、维持关系驱动的拒谏、保证权威驱动的拒谏。其次,分析了领导拒谏的形成机理,从谏言内容、谏言员工和谏言行为三方面考察领导者对员工谏言的认知评估过程,详细讨论了组织距离如何通过领导注意间接影响领导拒谏,并探讨了权力距离在领导注意与领导拒谏之间所具有的调节作用。本研究有助于推动领导拒谏的理论构建,拓展认知评估理论的应用,而且能为组织管理实践给予一定的参考与借鉴。  相似文献

This research note highlights the novelty of integrating location-based services (LBS) available on Smart Phones and Tablets into traditional resident attitude survey methodologies such as door-to-door data collection. It specifically reviews how the LBS technology available on mobile devices can be used to systematically capture GPS coordinates of one's residence and integrate this captured spatial information into software such as ArcGIS and SPSS for further analysis. By having GPS coordinates associated with respondents' answers, researchers have an additional layer of information available for conducting a multitude of tests previously not possible with subjective categorical spatial data. Two research applications using the spatial location of residences are provided as examples of how LBS available on mobile devices can be integrated within resident attitude projects. The use of LBS technology can help researchers better understand how the distance residents live from major tourist attractions influences their attitudes towards tourism.  相似文献

A large body of literature argues that the characteristics of exports matter for economic growth and development because some goods trigger positive externalities or are subject to increasing returns. Thus, for policy purposes, it is important to know whether a country’s export basket enjoys these productive opportunities. They have been associated with technological content of exports. However, measuring them is not easy. Previous methodologies to account for exports’ technological content used either R&;D data or trade data. The former is used to account for knowledge-intensive activities during the production phase and the latter to identify levels of ‘sophistication’ of exports based on exporting countries’ characteristics. Building on these contributions, this paper combines industry-based and product-based indicators to circumvent some of the shortcomings of the received literature, including the product-industry controversy (i.e. are the actual activities during the production process or the product characteristics what better accounts exports’ technological content?). We use data from Uruguay on direct and indirect R&;D spending from public and private sources and also trade data to build the sophistication index corrected by quality. We contrast our findings with existing methodologies to highlight our contribution.  相似文献

The paper investigates the impact of the host country’s environmental uncertainty on the choice of entry mode and also discusses the moderating role of technological heterogeneity in this relationship. Based on the resource-based view and institutional theory framework, we first analyze the investment motivation of emerging industries in emerging markets and evaluate the environmental uncertainty from two dimensions, including the institutional environment (country level) and industry environment (market level). Then, the theoretical predictions are empirically tested using 173 overseas investment events in China’s high-end equipment sector from 2010-2018. Our findings suggest that when the uncertainty of the industry environment is low, no matter how uncertain is the institutional environment, most firms tend to choose a cooperative strategy. Once the industry environment indicators become turbulent, a high degree of institutional environment uncertainty causes firms to evade trade barriers by choosing a new plant. Alternatively, choosing a relatively conservative mode, such as export. Meanwhile, technological capability weakens the influence of environmental uncertainty on entry mode.  相似文献
