In this article, we attempt to extend and nuance the debate on intellectual property (IP) strategy, appropriation, and open innovation in dynamic and systemic innovation contexts. We present the case of four generations of mobile telecommunications systems (covering the period 1980–2015), and describe and analyze the co-evolution of strategic IP management and innovation ecosystems. Throughout this development, technologies and technological relationships were governed with different and shifting degrees of formality. Simultaneously, firms differentiated technology accessibility across actors and technologies to benefit from openness and appropriation of innovation. Our analysis shows that the discussion of competitiveness and appropriability needs to be expanded from the focal appropriability regime and complementary assets to the larger context of the innovation ecosystem and its cooperative and competitive actor relations, with dispersed complementary and substitute assets and technologies. Consequently, the shaping of complementary and substitute appropriability regimes is central when strategizing in dynamic and systemic innovation contexts. This holds important implications for the management of open innovation, innovation ecosystems, platforms, and coopetition. 相似文献

ABSTRACTHow can we best protect and safeguard the progress of the #MeToo movement? This article presents 11 reforms designed to ensure the movement’s drive toward justice. These fall into three areas. The first concern process reforms designed to (a) protect all those involved—accusers and the accused—in investigations of sexual harassment, (b) end differential treatment of those found guilty, and (c) ensure punishments are commensurate with the crime and proportional in terms of other transgressors. The second set of reforms focus on transparency of the process, including clarifying (a) how to file charges, (b) who makes decisions, (c) relevant public information on how charges and procedures are followed, (d) what transgressions result in which punishments, and (e) how complaints are investigated to protect the rights and privacy of all. Finally, I address cultural issues that address (a) our portrayal of women, (b) our societal attempts to prepare young people so they can better protect themselves, and (c) attempts to encourage bystanders to intervene in the face of sexual harassment of others. 相似文献

考虑由新能源汽车租赁企业和政府组成的二级系统,在需求率为随机且与推广努力水平相关的市场环境下,建立了新能源汽车租赁企业和政府之间的博弈模型,探讨了分散决策、集中决策、收益共享与成本共担契约下的最优车队配置和推广努力水平,并对三种情形下的最优决策进行了比较和分析。研究结果表明:在分散决策情况下无法实现系统协调,通过引入成本共担与收益共享组合契约,当契约参数满足一定条件时,该组合契约模型不仅可以实现系统协调而且可以使系统成员达到帕累托改进。最后通过算例分析,验证了模型了可靠性和有效性。 相似文献

Open innovation and absorptive capacity are two concepts based on the idea that companies can leverage the knowledge generated externally to improve their innovation performance. The aim of this paper is to analyse the joint effect of open innovation and absorptive capacity on a firm's radical innovation. Open innovation is expressed in terms of external search breadth and depth strategies and absorptive capacity is described by distinguishing between potential and realized absorptive capacity. In order to test our hypotheses, we carried out empirical research in firms operating in high-technology industries. The results indicate that internal routines and processes for absorbing external knowledge help explain radical innovation as they show a significant effect of potential and realized absorptive capacity. Also, there is a moderating effect of absorptive capacity on open innovation. Specifically, potential absorptive capacity exerts a positive effect on the relationship between external search breadth and depth and radical innovation. Realized absorptive capacity moderates the influence of external search breadth. These findings confirm the complementary nature of absorptive capacity and open innovation search strategies on radical innovation. 相似文献

地方政府作为地方公共事务管理者,决策正确与否直接关系到公共管理活动的成败,并且在一定程度上影响地方经济发展的水平及其核心竞争力。由于我国地方政府现阶段决策主体多元性及其职能模糊性,一些重大决策失误现象屡屡发生,造成了有限资源的巨大浪费,严重影响了地方政府在人民群众中的威信和形象。对此,我国地方政府迫切需要优化重大决策机制,包括明晰体制内外决策主体的职能、第三方评估、公众参与、决策终身责任追究及倒查机制等,以推进地方政府决策的民主化、科学化和法治化。 相似文献

Influence plays a key role in reaching consensus among multiple actors involved in project-based decision-making processes. While prior literature devotes considerable attention to describing influence, little attention has been paid to influence at the individual level of the strategic project manager within the context of megaprojects. This research intended to fill this knowledge gap by identifying and describing the influence strategies that a strategic project manager applies when implementing innovation strategies on megaprojects. A qualitative case study was used to examine the complex social processes involved in a major UK capital investment programme. The findings underline a critical subset of influence strategies, notably higher-management support, inspirational appeal and bargaining. The study proposes a utilitarian structure of social power comprising selective, supportive and executory power bases. 相似文献

制度创新与人的全面发展 总被引:1,自引:0,他引:1
制度创新是人的全面发展的基本途径。从人的全面发展的视角看问题,适合于中国社会的理想制度模式应当是形式化、程序性、民主优先于自由、有利于杰出人才涌现、以人为本的非人格化制度。这种制度的创新,需要我们设定正确的制度创新理念,培养人们的创新精神和创新意识,积极探索制度创新的规律性,完备制度创新的实施技术。 相似文献
