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.

PDRG1 at the interface between intermediary metabolism and oncogenesis

PDRG1 is a small oncogenic protein of 133 residues. In normal human tissues, the p53 and DNA damageregulated gene 1(PDRG1) gene exhibits maximal expression in the testis and minimal levels in the liver. Increased expression has been detected in several tumor cells and in response to genotoxic stress. High-throughput studies identified the PDRG1 protein in a variety of macromolecular complexes involved in processes that are altered in cancer cells. For example, this oncogene has been found as part of the RNA polymerase Ⅱ complex, the splicing machinery and nutrient sensing machinery, although its role in these complexes remains unclear. More recently, the PDRG1 protein was found as an interaction target for the catalytic subunits of methionine adenosyltransferases. These enzymes synthesize S-adenosylmethionine, the methyl donor for, among others, epigenetic methylations that occur on the DNA and histones. In fact, downregulation of S-adenosylmethionine synthesis is the first functional effect directly ascribed to PDRG1. The existence of global DNA hypomethylation, together with increased PDRG1 expression, in many tumor cells highlights the importance of this interaction as one of the putative underlying causes for cell transformation. Here, we will review the accumulated knowledge on this oncogene, emphasizing the numerous aspects that remain to be explored.

The Intermediary Roles of Public Health Nurses (PHNs) in Utilizing Communication Robots (CRs) in Community Health Care Practice

Robot technology is expected to reduce the burden of medical professionals, a concern in the super-aged society. The aim of this article is to determine the intermediary roles of Public Health Nurses (PHNs) in using Communication Robots (CRs) in Community Health care. It is necessary to consider who will manage, and how to draw lines of responsibility when a problem occurs when using robots in the future. Regarding the mediator or intermediary role of PHNs in the use of CRs, PHNs are expected to be cognizant of varieties of robots for use with persons of diverse ages and health levels, as well as of robot performances. As one of the community healthcare workers who service the elderly living in the community, the role of PHNs as mediators or intermediaries is to pay attention to ethical and moral issues while working with CRs to manage the health of the community. Lack of understanding of the intermediary role might create possible ethico-moral issues in the future. Therefore, it is critical for PHNs to understand their role as intermediaries. In doing so, it is expected that older people at home will be able to live peaceful lives, as well as be physically and mentally healthy.

Characteristics of a Transactive Phenomenon in Relationships among Older Adults with Dementia, Nurses as Intermediaries, and Communication Robot

Healthcare for older adults with dementia is an important healthcare problem in Japan and in other developed countries. Importantly, healthcare workers in Japan are also getting older. In order to address solutions to this problem, using robots is being realized and is starting to assist healthcare and welfare practice needs. The aim of this study was to identify the characteristics of a transactive phenomenon in relationships among older adults with dementia, with nurses as intermediaries and with a cognitive skill-aid robot. Subjects were two institutionalized older adults who were diagnosed with dementia using Hasegawa’s Dementia Scale-Revised;a Kabochan (Nodding Kabochan) fixed with a remote-controlled speaker, Pechat (Kabochan with Pechat). Measurements of autonomic nervous activity were done using wearable electrocardiography attached to the subjects for four hours. Heart Rate Variability data were assessed at various frequency bands using a HRV software tool. In a continuously recorded data, interbeat (R-R) intervals were obtained for a 1-min segment using the maximum entropy method. In this study, the two major spectral components of HRV, the variances of the low-frequency (LF: 0.04 - 0.15 Hz) band and high-frequency (HF: 0.15 - 0.4 Hz) band, were calculated. Activities and behaviors of subjects transacting with Kabochan were observed by the expert nurses and video-recorded. Throughout the transaction period, observations were recorded of patients’ behavior, words uttered and over-all contents of the transactive conversation with the Kabochan or Kabochan with Pechat. Identified characteristics were transactive relationship phenomenon;changes in autonomic nervous system activity of persons with dementia are expressed as per one minute, linguistic response of elderly people, transactive relations among Kabochan, Kabochan with Pechat, and nurses as intermediaries. These were exhibited as Figures: Situation 1, A Sense of Fear, Situation 2, A Pleasant Sensation, and Situation 3, Misunderstanding and Confusion. It also showed that autonomic nervous system activity of persons with communication skills is actively changing in older adults with dementia. Conversation of adding Pechat to the Kabochan illustrated that nurses as intermediaries showed emotional conversations as established by effectively manipulating the Pechat. Also, it was revealed that if Kabochan with Pechat uttered words about patient’s personal information in a conversation, the patient felt a sense of fear. The researchers suggest that when developing future communication robot for elderly with dementia, it is necessary to consider, for an effective conversation, transactive relationships including nurses as intermediaries. The role functions of these intermediaries have been shown of high versatility, indicating that situations such as these can also be controlled by other healthcare providers such as by occupational therapists.

Optimal control of a quality supervision profit model for the electronic intermediary

Online customers execute transactions without inspecting products could expect to encounter risks of receiving products with unsatisfactory qualities,especially in food trans-actions.Thus quality supervision plays a key role in the establishment of trust as well as in the management of risk between online customers and sellers.Most papers in this field are in qualitative nature.In this paper,a quality supervision profit(QSP)model is formulated as a discrete-time optimal control problem.It is a quantitative approach,and it broadens the scope.of current research in the area.The quality efort level of online sellers(QELa)and the quality supervision level of the electronic intermediary(QSLm)are considered together with their cor-responding profit in the proposed model.The aim is to optimize an overall profit.A case study arising from Suichang's food traceability system(FTS)of farm produce online transaction is carried out in details.The results reveal that QELs,QSLm and the profit distribution coeffi-cient have a strong influence upon the profits of both sides.Finally,some concluding remarks,including potential further research topics,are given.

An Intermediary Organization Finds Potential Needs By Exploiting Serendipity

This paper intends to clarify the needs serendipity in creating new business. The authors will show that serendipity is capability method of finding potential needs and/or new markets. In economic society, potential needs and/or new markets are only partially exposed, such as an iceberg. Serendipity is a capability that can expose the potential hidden part through accidental opportunity. Something more concrete can be formed from the exposed parts. The authors describe cases that demonstrate the usefulness of serendipity. In one case, a high-tech start-up had intended to use medical electronic equipment and/or industrial electronic equipment as the first application of their core technology. In these markets, they were competing with established major companies, so this start-up had difficulty entering these markets. However, a specific distributor found potential needs that were met by the start-up＇s products, and has created a new market by combining their core technology with social needs. The authors define serendipity capability by analyzing this case example and argue that serendipity can contribute to finding opportunities and solving social issues.

Empirical Analysis on the Financial Intermediary Development and the Economic Fluctuation in China

This article analyzes the relationship between financial intermediary development and economic fluctuation in the last 50 years in China. It was found that a steady and long-term relation existed between these two variables, and that different aspects of the development of the financial intermediary system had different effects on the economic fluctuation. The improvement of the intermediary＇s efficiency can repress the economic fluctuation , but the increase of financial intermediaries can intensify the fluctuation. On that basis, some suggestions about the development of the financial intermediary are proposed in this essay.

数字普惠金融对科技成果转化的影响机制与门槛效应分析

为高效利用数字普惠金融促进科技成果转化,利用2011—2021年我国31个省份面板数据,采用固定效应模型和以创新参与度、创新产出能力为中介的中介效应模型,基于异质效应与非线性效应的多重视角,实证研究数字普惠金融对科技成果转化的影响。研究发现,第一,数字普惠金融会对科技成果转化的直接效应为正,且存在累积递增效应;第二,机制分析表明,数字普惠金融可以通过提高创新参与度和创新产出能力进而促进科技成果转化,而且创新产出能力的中介效应更强;第三,异质性分析表明,在中西部地区,数字普惠金融对科技成果转化的积极效应更强;第四,数字普惠金融对科技成果转化的影响存在显著动态非线性关系,在门槛值之前存在阻碍作用,只有越过门槛值后才会呈现边际效应递增的非线性特征,创新产出能力和创新参与度的非线性调节效应都是积极且显著的,但是创新参与度的调节效应要小于创新产出能力。由此提出应积极发展我国的数字普惠金融、推动信息技术和传统金融高效融合、推动数字普惠金融与科技成果转化的深度融合、实施差异化动态化的科技成果转化策略等相关对策建议。

合理配置中介机构的法律责任、科学厘清中介机构的责任边界是注册制下确保中介机构归位尽责的前提和基础。中介机构的责任边界具体包含中介机构与发行人的责任边界、各中介机构彼此之间的责任边界以及中介机构自身的责任厘定三个层次。这三个层次的责任边界划分是由外及里、纵深递进的关系,各层次的结构逻辑以及不同层次之间的勾连,本质上是基于各中介机构在信息披露制度中的职责定位与其应当秉持的勤勉尽责标准相结合而形成的责任划分体系。

绿色金融、产业结构升级与海洋经济高质量发展——基于环境规制调节的中介模型

绿色金融是促进“双碳”目标实现和提升海洋经济高质量发展水平的重要抓手。论文基于2009—2019年我国11个沿海省市的面板数据,运用中介模型考察了绿色金融对海洋经济高质量发展的影响及其传导路径。在此基础上构建有调节的中介效应模型,基于产业结构高级化和合理化的中介路径与环境规制的调节效应探究绿色金融对海洋经济高质量发展的路径机制。研究发现:首先,绿色金融显著促进海洋经济高质量发展,产业结构高级化和合理化均存在正向中介效应;其次,环境规制正向调节绿色金融发展对产业结构升级的积极影响,同时强化产业结构升级对海洋经济高质量发展的促进作用,且在绿色金融对海洋经济高质量发展的直接效应中起到显著正向调节作用。

产业转型升级、城乡收入差距与居民消费

居民消费是畅通国内大循环的关键环节和重要引擎,产业转型升级优化了消费供给。本文实证分析了产业转型升级对居民消费的直接影响,以及通过城乡收入差距所产生的间接影响。研究发现,经济高质量发展期间,产业转型升级显著促进居民消费;城乡收入差距在产业转型升级和居民消费间的中介效应显著,产业转型升级会通过缩小城乡收入差距间接促进居民消费;产业转型升级对居民消费的影响以及城乡收入差距的中介效应均存在区域异质性,西部地区的直接影响和中介影响均强于中部和东部地区。因此,应该通过供给侧为居民提供丰富、高质量的商品,满足人民日益增长的消费需求;通过产业转型升级带动就业,提高劳动力收入,缩小城乡收入差距,同时积极防范部分地区在实施产业转型升级政策时出现扩大城乡收入差距等问题。

中国式现代化的纵向叙事逻辑

在中国式现代化的叙事逻辑阐释上,目前学界呈现一种“重横向逻辑,轻纵向逻辑”的不均衡态势,“逻辑起点—逻辑中介—逻辑终点”的纵向叙事逻辑屈指可数。以马克思唯物史观为指引,中国式现代化的纵向叙事逻辑在于:现实的人是中国式现代化得以形成的最大可能,是中国式现代化的逻辑起点。中国式现代化的逻辑中介作为连接逻辑起点(最大可能)和逻辑终点(最大结果)的中间枢纽,包括以马克思主义为指导的思想中介、以党的全面领导为根本的组织中介、以高质量发展为任务的主题中介、以国家制度体系为架构的基础中介、以中华民族伟大复兴中国梦为导向的目标中介、以面临的内外部环境为形势的条件中介。人的现代化是中国式现代化得以实现的最大结果,是中国式现代化的逻辑终点,包括以人民为中心的现代化和人的自由全面发展。科学合理地精准定位并论证好中国式现代化的纵向叙事逻辑,对于新时代全面推进社会主义现代化建设事业意义重大,成为推进中国式现代化向纵深发展的时代要求。

机构投资者的“机构化”——基于公募基金持有者结构的实证分析

大力发展机构投资者、着力打造现代金融企业是证券市场走向成熟的标志,也是中国特色现代金融体系发展和优化的关键。然而已有研究多聚焦于机构投资者持股对于公司经营治理等方面的影响,却忽视了这类机构投资者自身股东结构“机构化”的影响。选择公募基金作为机构投资者代表,研究发现“机构化”程度高的基金未来能取得更高的超额收益。为进一步分析内在机制,论文提出了“私有信息机制”“激励机制”和“监督机制”三种假说,检验发现机构投资者不仅可以“用脚投票”,更对公募基金存在积极的激励和监督作用,对基金经理的选股能力和投资的耐心程度有显著的正向影响。研究还发现机构投资者持有的稳定性也是提高基金未来收益的关键因素。论文就金融中介链条问题展开了初步探索,为理解我国资本市场中机构投资者作用提供了更多实证细节和证据,同时也丰富了公募基金领域的研究思路。

金融结构对科技金融耦合系统脆弱性的影响

随着科技与金融耦合的不断深入,对其负向作用及脆弱性的研究不容忽视。运用熵值法对我国2006—2020年省际科技金融耦合系统脆弱性指数进行测算,在此基础上引入金融结构,检验金融结构对科技金融耦合系统脆弱性影响的本地效应及空间溢出效应。研究发现:(1)各地区金融结构市场化程度呈上升趋势;(2)总体而言,金融结构市场化水平提高有利于改善系统脆弱性;(3)不同经济发展水平、金融结构对系统脆弱性的影响效果不同;(4)全国层面,金融结构正向空间溢出效应会加剧周边地区系统脆弱性,分地区层面,东部地区金融市场占比增加会带动相邻省份系统脆弱性改善,而中西部地区反而起到加剧作用。因此,应推动金融市场发展、完善银行中介服务。

“资本+技术”融合驱动下产业转移升级与经济高质量发展

技术创新作为经济高质量发展的持久动力,离不开充足的资本支持。本文基于我国30个省区市(未包括港澳台和西藏)面板数据,研究资本与技术融合驱动、产业转移升级和经济高质量发展的关系。研究结果显示:在产业转承两地,资本与技术融合驱动水平在促进经济高质量发展的同时,能够正向调节产业结构升级对经济高质量发展的促进作用;然而,在资本与技术融合驱动下,产业转移对产业结构升级和经济高质量发展的影响具有显著的地区异质性和行业异质性;机制分析显示,产业承接地的资本与技术融合驱动主要通过推动产业结构升级的独立中介效应渠道和“抑制产业转移承接→促进产业结构升级”的链式中介渠道推进经济高质量发展,产业转出地的资本与技术融合驱动主要是通过促进产业结构升级的中介效应渠道推进经济高质量发展。本文提出促进资本与技术的融合发展,立足区域差距制定差异化的发展战略,重视传统行业与高新技术行业的深度融合,着力推动承接地产业结构迈向中高端等建议,以此驱动经济高质量发展。

营商环境优化、数字经济发展与经济发展质量提升——基于281个城市的实证研究

营商环境优化是经济发展质量提升的外部保障与动力引擎。基于281个城市2011-2020年的面板数据,实证分析了营商环境对经济发展质量的影响。结果表明,营商环境优化显著提升了经济发展质量,该结论在一系列稳健性检验后仍然成立;异质性分析发现,城市能级越高、地理位置越靠东,营商环境对经济发展质量的影响越强;空间效应显示,营商环境优化提高了邻近城市经济发展质量;机制分析发现,数字经济是营商环境影响经济发展质量的作用路径;门槛效应分析表明,营商环境与数字经济水平越高,营商环境对经济发展质量的促进作用越强。最后从营商环境、数字平台和集群发展等角度提出政策建议。

政务数据开放运营制度的目标偏离及纠偏

政务数据开放之价值目标,应定位于在公平合理条件下保障多元的市场和社会主体获取和利用公共数据,从而推动政务数据利用的经济、政治效益和社会福利的整体增长。国家应协调政务数据开放的多元价值目标,为社会主体公平利用政务数据提供实质条件,形成一套兼顾多元利益、具有系统性和整体性的开放、运营和管理体制。当前一些地方规定政务数据归政府所有,进而采取“国有资产管理式”策略进行授权运营的做法,缺乏法理层面的依据,在制度功能上也将引发“与民争利”和“地方数据壁垒”的双重负面效果,亟需予以纠偏。政务数据授权运营制度的再建构,需要考虑政务数据开放的价值目标,从而匹配相应的手段选择。应考虑建立“二元授权运营机制”:一是在数据基础设施层面,完善“公私合作履职式”的授权运营模式,避免过度商业导向和政务数据资产化的法律风险,增强政务数据开放的便捷性与数据生态的构建;二是在具体政务数据的管制策略层面,将侧重政务数据资源资产化思路的“国有资产管理式授权运营”,转变为基于风险防控与市场秩序而审慎限定数据利用主体资格的授权运营模式,从而保障政务数据利用的公平竞争,提升政务数据利用的社会效益。
