This paper aims to understand what goes on in the black box of successful, joined-up ICT-enabled service transformation, where complex interactions and integration must occur among the horizontal processes internal to a joined-up service delivery network, the vertical top-down processes of the organizations involved, and the change processes caused by using ICTs. A new conceptual framework is developed and applied to an illustrative case study of successful, joined-up service transformation in New Zealand.  相似文献

Since the invention of the European Patent System, national patent systems have continued to co-exist, although they did lose appeal. How have the different national systems been affected in view of their characteristics? In order to answer this question a constant-market-share (CMS) analysis is carried out. While on a theoretical level, the different elements adding to the appeal of each patent system are discussed, the CMS-analysis reveals the importance of country size in that the national systems of smaller countries lose.  相似文献

本文将专利竞争力划分为现实竞争力与潜在竞争力两个层次,从专利拥有、运营、保护、服务、投入、创造和管理七个方面构建专利竞争力指数,对中国省际专利竞争力进行测算,结果显示,中国现阶段区域专利竞争力总体水平不高,而且省际之间差距很大。本文将所选取的31个省、直辖市、自治区的专利竞争力划分为三类:第一类为现实竞争力和潜在竞争力均高于国内平均水平的地区,此类地区可通过打造服务助力型政府、激励企业丰富专利拥有和专利运用方式来提升专利竞争力;第二类为专利现实竞争力不强,但有较强的潜在竞争力的地区,此类地区的政府在培育专利竞争力方面应定位于规划、布局和引导,企业则应转变观念,树立专利是市场竞争有效武器的观念;第三类为专利现实竞争力和潜在竞争力均很弱的地区,此类地区需要主导推动型的政府来推动地区专利竞争力的提升。  相似文献

This research examined how operational outcomes, relational outcomes and business performance are affected by a collaboration project between buyers and suppliers in a supply chain. It is hypothesized that interdependence of knowledge and process, supply chain partner insight, and the level of collaboration between the firms affect the outcomes of a collaboration project. Survey data from buyers and suppliers from a wide range of industries and organizations were used in this analysis. Among these participants, higher levels of collaboration led to improvements in operational and relational outcomes, which together led to improvements in asset utilization, competitive position, organizational performance, and profitability.  相似文献

网络结构特征影响企业知识转移与知识组合效果,进而对创新绩效产生复杂作用。利用我国165家上市企业2007—2018年专利面板数据,实证检验企业知识与协同双层网络嵌入对二元创新绩效的影响,并分析战略柔性和开放度对上述关系的调节作用。研究结果表明,企业知识网络结构洞正向影响利用式创新绩效,负向影响探索式创新绩效;协同网络结构洞与二元创新均存在负相关关系。同时,战略柔性和开放度调节双层网络结构洞与二元创新的关系,且变量间存在有效匹配关系:知识网络结构洞—开放度促进利用式创新绩效提升,而协同网络结构洞—战略柔性促进探索式创新绩效提升。研究结论为解决结构洞与企业创新关系的分歧带来新思路,同时为企业创新绩效提升提供理论借鉴。  相似文献

数字产业具有前沿性、复杂性和高度不确定性,技术标准国际化是数字产业保持全球竞争力的重要举措。采用纵向单案例研究法,以昕诺飞为研究对象,探索企业推进技术标准国际化的路径及机制。结果表明,昕诺飞实现技术标准国际化的主要路径是基于自主研发或收购专利组建标准联盟或专利联盟并制定发布联盟标准,进而将其转化为国际标准、目标国国家标准和团体标准;企业可基于标准开展相应认证检测,形成“联盟+标准+专利+认证检测”的闭环,实现“技术专利化—专利标准化—标准国际化—市场垄断化”的良性循环,以维持企业长期竞争优势;推进技术标准国际化的关键在于组建联盟,我国数字产业可通过“标准联盟+专利联盟”的双联盟策略,形成核心层稳固的开放式战略联盟,通过构建共生演化生态系统推进技术标准国际化。  相似文献

The strategic importance of monitoring technological changes is highlighted given the ever faster pace and increasing complexity of technological innovation. In this respect, patent citation analysis has been the most frequently adopted tool among others. However, patent citation analysis is subject to certain drawbacks that stem from only consideration of citing-cited information and time lags between citing and cited patents. This study proposes a formal concept analysis (FCA)-based approach to developing a dynamic patent lattice that can analyze complex relations among patents and monitor trends of technological changes. The FCA is a mathematical tool for grouping objects with shared properties based on the lattice theory. The distinct strengths of FCA, vis-á-vis other methods, lie in structuring and displaying the relations among objects from a massive amount of data. For the purpose of technology monitoring, the FCA is modified to take into account time periods and changes of patent keywords. A patent context is first constructed with the aid of domain experts and text mining technique. Two types of dynamic patent lattices are then developed by executing the modified FCA algorithm. A case study of laser technology in lithography for semiconductor manufacturing shows that the suggested dynamic patent lattice has considerable advantages over conventional patent citation maps in terms of visualization and informative power.  相似文献

药品专利权与公众健康权的冲突由来已久,通过政府药品管制及现存法律制度提供的强制许可与平行进口路径,并不能得到有效解决冲突。政府基于责任伦理在国民收入第二次分配中的补偿机制,应当是现阶段公众健康权实现的较为可行的政策选择。  相似文献

In this study, we provide support for the argument that patents are at their maximum value at those times when they are under litigation. We develop a heuristic procedure to determine the way in which such patents under litigation form a network of patent family members, and then go on to examine the priority patents involved. We subsequently attempt to develop a simple procedure to further identify both the ‘critical’ and ‘significant’ chains within our proposed patent priority network. We suggest that the ‘critical’ and ‘significant’ chains that are created within the above network provide companies with important information which will ultimately provide them with valuable support for the subsequent decision of their patent portfolio strategies.  相似文献
