科技创新团队创新增效运营模型研究

在科技创新团队运营阶段,运用生产效率测定指标构建团队创新增效运营模型,并提出增效的重点聚集于团队活动计划,而团队计划的重点是从假设探索向实践运用的方法研究。以某企业总部及其事业部18个科技创新团队为研究对象,在两个时间节点(项目开始后的第3个月和第9个月)对创新增效要因和创新效率之间的关系进行实地调查,研究结果显示:创新增效60%~80%的要因聚集于团队活动计划,第3个月以假设探索为中心的团队活动计划对于创新增效的影响极大,而第9个月以实践为中心的团队活动计划对于创新增效的影响极大。并验证了以上两个时间节点中团队活动计划重点的差异性。     

改革开放四十年:科技金融的实践探索与理论发展

改革开放四十年来,随着科技创新的发展,科技金融从当初政府政策业务实践层面走向国家战略层面,成为当前“双轮驱动”的重要组成部分。从最初的“科技与金融结合”发展到当前的“金融、科技与产业”的深度融合发展态势,科技金融的内涵和外延在变化,作为具有一定中国国情特色的学术范畴的理论研究也相对滞后。针对科技金融的实践探索历程及发展趋势,需要从“资本工具”、“创新政策”及“经济范式”三个维度去把握科技金融的本质及相关特征,进而丰富和发展相关理论体系,从而更好的发挥理论的政策价值和实践指导意义。

石油资源危机与石化企业倒闭的动力学机制

该文建立了石油资源短缺下国际石化企业竞争的非线性动力学模式,揭示了倒闭的大型石化企业数与石油短缺率的内在约束关系以及石化企业倒闭数与最强（大型）石化企业对石油占有率的内在约束关系。研究结果表明,对于D>q,即石油的短缺率大于国际石化系统最强（大型）石化企业对国际石油市场和资源的占有率,石化企业的演化存在以下规律和特点：（1）石化系统里的最强（大型）石化企业n1将不可避免地倒闭。随着石油短缺率的增加,伴随最强（大型）石化企业走向倒闭的石化企业依次是第二、第三、第四、……强（大型）的石化企业,D/q的值越大型,石化系统所倒闭的大型石化企业数越多。倒闭的驰豫时间量级为50d—500d左右; （2）短缺石油后的幸存石化企业将经历三个演变阶段： 抵抗阶段,恢复阶段和稳定阶段。经过多平衡态共存和最强（大型）石化企业的不断替代过程后,国际石化企业系统达到新的平衡态,此时石化系统企业强弱的序严格地遵守偶数-奇数对称或奇数-偶数对称规律。即如果由于石油的短缺而导致系统有奇数个石化企业倒闭,则适应稳定后的系统的石化企业的强弱序服从偶数-奇数对称规律,即原序号为偶数的石化企业为强（大型）者,而原序号为奇数的石化企业为弱者。如果系统有偶数个石化企业倒闭,则适应稳定后的系统的石化企业的强弱序服从奇数-偶数对称规律,即原序号为奇数的石化企业为强（大型）者,而原序号为偶数的石化企业为弱者。所以,对于依赖于石油的各类不同的石化企业,把握石油的短缺率及石化系统最强（大型）企业对国际石油市场和资源的占有率十分重要。     

Anticipated IT infrastructure and supply chain integration capabilities for RFID and their associated deployment outcomes

This study looks at the perceived ability of components of IT infrastructure integration and supply chain process integration to predict specific radio frequency identification (RFID) system deployment outcomes—exploration, exploitation, operational efficiency, and market knowledge creation. Data for this pilot research study was collected using a survey questionnaire administered online to members of the Council of Supply Chain Management Professionals (CSCMP). It was hypothesized that data consistency and cross-functional application integration, both elements constituting IT infrastructure integration, and information flow integration, physical flow integration, and financial flow integration, all elements constituting supply chain process integration would be positively associated with and predict the four RFID system outcomes. Multiple regression results show partial support for all four proposed hypotheses. Cross-functional application integration and financial flow integration predicted exploration, while data consistency and physical flow integration predicted exploitation. Data consistency and cross-functional application integration, on the other hand, predicted both operational efficiency and market knowledge creation. Supply chain managers planning to deploy RFID systems are alerted to the criticality of these IT infrastructure issues as they brace for a likely widespread implementation of RFID in supply chains they participate in.     

Enabling innovation in the face of uncertainty through IT ambidexterity: A fuzzy set qualitative comparative analysis of industrial service SMEs

Taking a configurational approach, this paper investigates the causal configurations of IT ambidexterity (i.e., IT capabilities for exploitation and exploration), dynamic capabilities (i.e., innovation and networking capabilities) and environmental uncertainty that are associated to service innovation performance in small and medium-sized enterprises (SMEs). Results from a fuzzy set qualitative comparative analysis (fsQCA) of 63 industrial service SMEs show that these firms attain high service innovation performance with three different configurations under conditions of high uncertainty. Two configurations highlight the importance of IT exploration capabilities (combined with the absence of innovation and networking capabilities in one configuration and with the absence of networking capabilities and IT capabilities for exploitation in another), whereas another configuration accentuates the importance of IT exploitation capabilities (combined with the presence of innovation and networking capabilities). Our study contributes to the literature in multiple ways. For instance, due to the equifinal properties of the configurational approach, our results suggest that SMEs can attain high innovation performance through both sequential and simultaneous IT ambidexterity, thus providing a starting point for reconciling competing views of IT ambidexterity. Other contributions to theory and practice and avenues for future research are also discussed.
