The impact of cognitive and emotional factors on the customer's decision to adopt a new technology has long been at the core of innovation and marketing literature. Today, the proliferation of personal technologies makes the understanding of the adoption process of such innovations a vital issue. This article, moving from long-established technology adoption theories, integrates affective factors to propose a comprehensive framework to interpret and orient innovation and marketing approaches of companies. To do this, we review a rich literature from the domains of management, information systems, marketing and cognitive psychology, identifying six possible sources of perceived value for personal technologies, hence attitude to adopt them: functional value, monetary value, social value, entertainment value, epistemic value and aesthetic value. After defining and framing them in the extant literature, we discuss how the framework may be adopted in practice to support Companies' strategies in the surprisingly under-explored industry of personal technologies.  相似文献

基于CAS理论视角,明确生物制药产业技术创新能力的定义,构建生物制药产业技术创新能力系统的概念模型图,找出组成该系统的产业技术创新流程及惯例,并阐述生物制药产业技术创新能力系统的演化机制。与此同时,构建生物制药产业技术创新能力系统演化的遗传算法模型,并通过Matlab软件仿真生物制药产业技术创新能力系统的演化。结果表明,产业技术扩散对生物制药产业技术创新能力强度有显著增强作用,而产业吸收能力作为技术创新惯例则在适应度函数的迭代计算中起到显著约束的作用。  相似文献

Globally, small and medium-sized enterprises (SMEs) are engines of economic growth and job creation. After the pandemic, innovation activities have become more critical than ever as a generator of competitiveness. Therefore, we need to better understand the factors that lead to innovation in SMEs. This study aims to analyze the role of relational capital and technology orientation in innovation to appreciate its final impact on firm performance. The main results reveal a strong positive effect of relational capital on innovation, but the effect is not so strong as firm performance. We also found a strong positive effect of relational capital on technology orientation. Finally, we offer some clues in the debate on technology as a source of innovation and how relational capital and technology orientation are related to a firm’s performance. The results reveal significant implications for innovation policies and relational capital strategies for SMEs.  相似文献

Collaboration in large-scale projects introduces challenges involving both coordination (the ability to collaborate) as well as cooperation (the willingness to do so). Existing research has shown how modular designs can improve coordination by locating interdependencies within rather than between different modules. Based on an in-depth case study of collaboration in a large-scale infrastructure project, our study highlights an effect of modularity on collaboration that previously has been overlooked. Specifically, we show that while modular designs may help overcome coordination challenges by reducing interdependencies between modules, they can in turn hamper collaboration by emphasizing specialization within modules. Therefore, though existing work typically perceives modularity and integration as opposites, we clarify how they can also act as complements. In particular, we show how firms need to complement modular designs with integrating practices that stimulate cooperation. Overall, we contribute to the literature on collaboration and modularity by explaining when and how organizations can combine modularity and integration.  相似文献

This study investigates the effect of project-level collaboration breadth (i.e., the number of collaboration partner types) and collaboration depth (i.e., the intensity of the interactions with these partners) on the incremental and radical innovation performance of innovation projects. The econometric analyses, based on a Community Innovation Study sample of 218 innovation projects conducted in German manufacturing companies, reveal inverted U-shaped relationships between collaboration breadth and radical innovation performance and between collaboration depth and incremental innovation performance. These curvilinear effects speak to the high sensitivity of innovation projects to the extent of collaborative activity, which implies that practitioners should exert caution in managing collaborative innovation projects. This study contributes to the understanding of project-level open innovation and to the overall understanding of the performance effects of innovation collaboration, which, following recent assertions in the literature, could be flawed by analyses conducted at the organizational level.  相似文献

In this paper we develop a novel multi-stage integrative framework for technology foresight-planning. This framework integrates econometric analysis and a technology foresight procedure to predict: (i) the most COVID-19 resilient industries at the national level; and (ii) the most adversely affected industries (due to prior investment in innovation) that requires public support. Our econometric results show that the pandemic has induced a ‘double-edge sword’ effect of innovation on firm’s COVID-19 adaptable capacity (CAC). Costly innovation undertaken before the pandemic can be bad for firms if it compounds the problem of declining post-pandemic outbreak profit and optimism. Contrarily, firm level innovation improves firm’s CAC as the prior innovators’ profitability are found to have above-even odds of rebounding quickly post-pandemic outbreak. Our empirical analysis focuses mostly on developing economies, where firms are most likely implementing only incremental (non-frontier) innovation and thus our results should be generalized with caution.  相似文献
