本研究提出了基于核心技术与辅助技术匹配的二次创新及其演化模型,详细归纳了后发企业创新演化路径,以解释中国本土企业的创新成功。通过对中兴通讯案例的编码和归类,本文界定了后发企业核心技术与辅助技术的学习与相关创新。通过对纵向分析,后发企业的创新可以分为三个阶段:在狭义二次创新阶段,后发企业进行核心技术引进模仿和本地辅助技术的利用型创新,为核心技术适配本地的辅助技术;在后二次创新阶段,后发企业进行辅助技术探索和核心技术利用,跟踪国外新兴核心技术,进行基于辅助技术研发的价值创造型创新;在一次创新阶段,后发企业进行核心技术探索,并进行辅助技术利用以推动核心技术创新。本文归纳了两个理论命题:第一,发展中国家后发企业的创新是一个核心技术从模仿引进、利用创新到探索创新的演化过程,辅助技术常常先于核心技术进入探索阶段;第二,后发企业核心技术的利用创新驱动了辅助技术探索,核心技术探索创新驱动了辅助技术利用。  相似文献

There is a natural order to most events in life: Everything from learning to read to DNA sequences in molecular biology follows some predetermined, structured methodology that has been refined to yield improved results. Likewise, it would seem that firms could benefit by adopting and implementing technologies in some logical way so as to increase their overall performance. In this study of 555 hospitals, we investigate the order in which medical technologies are transformed into information technologies through a process of converting them from stand‐alone technologies to interoperable, integrated information systems and whether certain configurations of sequences of integration yield additional value. We find that sequence does matter and that hospitals that integrated foundational technologies first—which in this case are known to be more complex—tend to perform better. Theoretical and practical implications of this finding and others are discussed.  相似文献

Risky energy technologies are often controversial and debates around them are polarized; in such debates public acceptability is key. Research on public acceptability has emphasized the importance of intrapersonal factors but has largely neglected the influence of interpersonal factors. In an online survey (N = 948) with a representative sample of the United Kingdom, we therefore integrate interpersonal factors (i.e., social influence as measured by social networks) with two risky energy technologies that differ in familiarity (nuclear power vs. shale gas) to examine how these factors explain risk and benefit perceptions and public acceptability. Findings show that benefit perceptions are key in explaining acceptability judgments. However, risk perceptions are more important when people are less familiar with the energy technology. Social network factors affect perceived risks and benefits associated with risky energy technology, hereby indirectly helping to form one's acceptability judgment toward the technology. This effect seems to be present regardless of the perceived familiarity with the energy technology. By integrating interpersonal with intrapersonal factors in an explanatory model, we show how the current “risk–benefit acceptability” model used in risk research can be further developed to advance the current understanding of acceptability formation.  相似文献

Risk Perception and Social Acceptability of Technologies: The French Case   总被引:2,自引:0,他引:2  
The authors present results of a February 1987 survey on judged frequency of mortality causes and risk perception of technologies in a representative sample of the French population. Although the French context is very different, and the impact of public controversies have been very limited on technological choices such as the nuclear energy program, strong similarities in risk perception of technologies are observed with results from U.S. surveys. Results, which could be worthwhile for other countries, suggest that risk perception is influenced by two different types of components. The first influence is the global feeling of "security" that society procures to its members. Such feeling depends on the individual's socioeconomic status, subjective state of health, and personal discomfort in daily life, and explains individual aversion to risk independently of the mortality causes or technologies involved. The second influence is the degree of perceived social legitimization of the activities involving risks. Risks of medical and transportation activities are strongly opposed to illegitimate risky behaviors (smoking, drugs, alcohol); technologies which have been an object of public debate (nuclear plants, the chemical industry, lead in gasoline) have an intermediate position reflecting the remaining uncertainties of public opinion about their risk–benefit balancing. Tentative conclusions for risk communication are proposed.  相似文献

大量可再生能源和存储设施集中或分布接入电网,缓解了电网的供给压力,但同时也对电力系统安全造成新的威胁。合理使用新能源和可存储设施使之更好为电网服务,是现代电网亟待解决的一个问题。本文对有可存储设备和可再生能源并网的电力系统进行研究,根据可再生能源在实际生活中的情形,将其划分为两类:私人新能源发电和公共新能源发电,其中私人新能源发电可供自身直接使用,多余部分并入电网,而公共新能源发电直接并入电网,然后针对上述复杂情形,结合用户实际需求,以所有用户效用最大化、成本最小化为目标函数,建立优化模型,给出了一种既有可存储设备又有可再生能源复杂并网情况下用户优化用电策略——包括家用电器、新能源、以及存储设备充放电策略。对模型的性质进行研究,考虑到模型是凸规划,强对偶成立,用拉格朗日对偶算法给出了模型的解。求解过程中,由于目标函数是非光滑的,采用光滑化的技术将目标函数光滑化,将非光滑问题转化为光滑问题,进一步利用拟牛顿下降法求解。该策略能确保新能源得到优先、充分利用,体现用户效用最大化、成本最小化,同时可以避免由于新能源并网可能会造成电网不稳定情况的出现;光滑化的方法不但适用于本文,经过适当改进后也可适用于其他目标函数为非光滑的情况。仿真结果验证了模型的合理性和算法的可行性。  相似文献

Expert elicitations are now frequently used to characterize uncertain future technology outcomes. However, their usefulness is limited, in part because: estimates across studies are not easily comparable; choices in survey design and expert selection may bias results; and overconfidence is a persistent problem. We provide quantitative evidence of how these choices affect experts’ estimates. We standardize data from 16 elicitations, involving 169 experts, on the 2030 costs of five energy technologies: nuclear, biofuels, bioelectricity, solar, and carbon capture. We estimate determinants of experts’ confidence using survey design, expert characteristics, and public R&D investment levels on which the elicited values are conditional. Our central finding is that when experts respond to elicitations in person (vs. online or mail) they ascribe lower confidence (larger uncertainty) to their estimates, but more optimistic assessments of best‐case (10th percentile) outcomes. The effects of expert affiliation and country of residence vary by technology, but in general: academics and public‐sector experts express lower confidence than private‐sector experts; and E.U. experts are more confident than U.S. experts. Finally, extending previous technology‐specific work, higher R&D spending increases experts’ uncertainty rather than resolves it. We discuss ways in which these findings should be seriously considered in interpreting the results of existing elicitations and in designing new ones.  相似文献

Information and communication technologies (ICTs) are increasingly pervasive and continue to reshape our environment. This trend carries different risks. Therefore, the early sensitization of people to these risks, as well as improving their capacity for protective coping behavior, is essential. Based on the protection motivation theory (PMT), we examined with structural equation modeling the relationships between different components of threat and coping appraisal to explain protective and nonprotective responses. Calculations were performed with data from a representative survey on perception and use of ICT among German residents (N= 5,030). Our findings largely supported the proposed model: an increased perceived threat was positively related to the intentions to react protectively and nonprotectively. Perceived coping efficacy increased the protective and decreased the nonprotective responses. Negative affect enhanced the perceived threat and the nonprotective response, but inhibited protective intentions. The implications of these findings on how to sensitize people to the risks of these new technologies are outlined.  相似文献

Recent years have seen a drastic transformation in the organization of wholesale and retail markets. Where once clear distinctions between wholesale suppliers and retail competitors existed, now an era of blurring boundaries has emerged. This transformation has been marked by the introduction of online channels for suppliers to provide products directly to consumers while, at the same time, traditional retailers too persist. Thus, retailers are both wholesale customers and retail competitors of many manufacturers. The consequences of the rapid emergence of instances of such partial forward integration by suppliers are not yet fully known. To this end, we study how partial forward integration can affect competing firms' strategic investments. We find that integration shifts the environment from being one in which firms invest to undercut retail rivals to one in which firms invest more in boosting demand, even that of their competitors. A case in point is the tendency for a manufacturer to invest broadly in brand promotion (benefiting both itself and its retail competitor), rather than heavy promotion of its own sales channel. The shift in the nature of strategic investments arising from partial forward integration implies that such integration can benefit firms and consumers alike, even the firm which finds itself reliant on a competitor for supplies.  相似文献
