How does network intermediary affect collaborative innovation?Evidence from Chinese listed companies

Purpose:This study aims to explore how network intermediaries influence collaborative innovation performance within inter-organizational technological collaboration networks.Design/methodology/approach:This study employs a mixed-method approach,combining quantitative social network analysis with regression techniques to investigate the role of network intermediaries in collaborative innovation performance.Using a patent dataset of Chinese industrial enterprises,the research constructs the collaboration networks and analyzes their structural positions,particularly focusing on their role as intermediaries,characterized by betweenness centrality.Negative binomial regression analysis is employed to assess how these network characteristics shape innovation outcomes.Findings:The study reveals that firms in intermediary positions enhance collaborative innovation performance,but this effect is nuanced.A key finding is that network clustering negatively moderates the intermediary-innovation relationship.Highly clustered networks,while fostering local collaboration,may limit the innovation potential of intermediaries.On the other hand,relationship strength,measured by collaboration intensity and trust among firms,positively moderates the intermediary-innovation link.Research limitations:This study has several limitations that present opportunities for further research.The reliance on quantitative social network analysis may overlook the complexity of intermediaries’roles,and future studies could benefit from incorporating qualitative methods to better understand cultural and institutional factors.Additionally,cross-country comparisons are needed to assess the consistency of these dynamics in different contexts.Practical implications:The study offers practical insights for firms and policymakers.Organizations should strategically position themselves as network intermediaries to access diverse information and resources,thereby improving innovation performance.Building strong trust helps using network intermediary advantages.For firms in highly clustered networks,it is important to seek external partners to avoid limiting their exposure to new ideas and technologies.This research emphasizes the need to balance network diversity with relationship strength for sustained innovation.Originality/value:This research contributes to the literature by offering new insights into the role of network intermediaries,presenting a comprehensive framework for understanding the interaction between network dynamics and firm innovation.

Unity of Knowing and Doing

Chinese President Xi Jinping has emphasized the unity of knowing and doing on a number of occasions,saying that knowing is the premise,while doing is putting knowledge to work,and these two ideas have a mutually reinforcing relationship.UNITY of knowing and doing is a key concept in ancient Chinese philosophy.Discussions on knowing and doing can be traced back to the pre-Qin period(before 221 B.C.).

Innovation in Maritime Logistics Industry of Bangladesh for Doing Port Transport Business

Bangladesh has the lucrative maritime load centers or seaports to provide maritime logistics support as well as to do port transport business regionally with India, Nepal and Bhutan and internationally with China and Myanmar. Existing land ports as alternatives of dry ports are main strength of Bangladesh to connect with the seaports and offer port transport business for earning foreign exchange and able to play a vital role to develop the South Asia, SW part of China and Myanmar by serving the maritime logistics facilities timely and economically. In here, dry port concept is the main theme for developing port transport business where road, rail and waterways are the connectors or modes of transportation and seaports are the linking points with the sea world, Innovation is the key of success of a business idea and plan where maritime logistics business is the new opportunity of Bangladesh by using natural resources or seaport by mounting infrastructure facilities of nodes （seaport and dry port） and modes （road, rail and waterways） and adding speedy port transport for all. The intermodal freight transportation system is the new concept for creating the new era in the port transport business by using nodes, modes and technology innovatively. This research aims to find out the possible ways and innovations in maritime logistics for doing port transport business by using seaports and land ports by applying qualitative research methodology. The paper also describes the innovations of Rotterdam port as case study that facilitated the needs of a hinterland in Europe to explore the innovations for Bangladesh maritime logistics industry.

计及DoS攻击和通信时滞的电力系统负荷频率控制

针对电力系统通信网络中存在的时滞和DoS攻击现象,本文提出了基于采样特性的电力系统离散负荷频率控制方案。首先,计及电力系统负荷波动的情况,在多区域电力系统负荷频率控制系统(LFC)模型的基础上,将通信网络中DoS攻击的危害量化为采样信号连续丢失数,并分别考虑通信网络中通信时滞和输出信号采样特性,建立包含输出状态反馈控制器的电力系统LFC模型。其次,基于此模型,利用含有控制命令更新周期、DoS攻击导致的最大采样信号连续丢失数、通信时滞、H_(∞)稳定指标的双边闭环Lyapunov泛函、LMI技术,提出LFC系统满足一定H_(∞)指标的稳定准则,并给出离散状态输出反馈LFC控制器的设计及求解方法。最后,本文以单区域和双区域LFC系统为例进行了仿真验证。结果表明:与已有文献方法相比,本文方法在保持系统H_(∞)渐近稳定前提下,能够容忍更大的通信时滞,且结果的保守性更低;同时可以看出本文所设计的控制器在保证H_(∞)稳定性能的基础上,对一定能量限制的DoS攻击具有弹性的防御性能。因此本文方案的有效性和优越性得到了验证。
