An Analysis of Knowledge Sharing Approaches for Emerging-technology-based Strategic Alliances in Electronic Industry

Emerging technologies are now initiating new industries and transforming old ones with tremendous power. They are different games compared with established technologies with distinctive characteristics of knowledge management in knowledge-based and technological-innovation-based competition. How to obtain knowledge advantage and enhance competences by knowledge sharing for emerging-technology-based strategic alliances （ETBSA） is what we concern in this paper. On the basis of our previous work on emerging technologies＇ distinctive attributes, we counter the wide spread presumption that the primary purpose of strategic alliances is knowledge acquiring by means of learning. We offers new insight into the knowledge sharing approaches of ETBSAs - the knowledge integrating approach by which each member firm integrates its partner＇s complementary knowledge base into the products and services and maintains its own knowledge specialization at the same time. So that ETBSAs should plan and practice their knowledge sharing strategies from the angle of knowledge integrating rather than knowledge acquiring. A four-dimensional framework is developed to analyze the advantages and disadvantages of these two knowledge sharing approaches. Some cases in electronic industry are introduced to illustrate our point of view.

Medi-Block Record Secure Data Sharing in Healthcare System:Issues,Solutions and Challenges

With the advancements in the era of artificial intelligence,blockchain,cloud computing,and big data,there is a need for secure,decentralized medical record storage and retrieval systems.While cloud storage solves storage issues,it is challenging to realize secure sharing of records over the network.Medi-block record in the healthcare system has brought a new digitalization method for patients’medical records.This centralized technology provides a symmetrical process between the hospital and doctors when patients urgently need to go to a different or nearby hospital.It enables electronic medical records to be available with the correct authentication and restricts access to medical data retrieval.Medi-block record is the consumer-centered healthcare data system that brings reliable and transparent datasets for the medical record.This study presents an extensive review of proposed solutions aiming to protect the privacy and integrity of medical data by securing data sharing for Medi-block records.It also aims to propose a comprehensive investigation of the recent advances in different methods of securing data sharing,such as using Blockchain technology,Access Control,Privacy-Preserving,Proxy Re-Encryption,and Service-On-Chain approach.Finally,we highlight the open issues and identify the challenges regarding secure data sharing for Medi-block records in the healthcare systems.

油气企业科技创新人才价值溯源分成评估

科技创新是发展新质生产力的核心力量,而科技创新人才是创新过程中的第一要素。作为油气生产的主要参与主体,油气企业要实现高水平科技自立自强,归根结底要依靠拥有高水平创新能力的人才队伍。为了激发科技人才创新活力动力,在人才价值创造与评估现状分析的基础上,依据生产全要素视角下的科技创新价值分享理论与方法,建立了油气企业科技创新人才价值溯源分成评估方法。研究结果表明:(1)油气企业科技创新是一个系统性的复杂过程,匹配油气企业科技创新特征、具有产业适应性的人才价值评估理论与方法较少;(2)油气企业科技创新人才价值溯源分成,是以油气科技创新成果经济价值评估结果为前提对参与成果创造的团队和个人按照实际贡献进行价值追溯与量化的过程,需要通过对单项科技创新成果经济价值溯源和科技创新成果完成人价值溯源两次溯源来实现;(3)以创新成果为导向的科技创新人才价值贡献率是人才价值溯源分成的核心参数,由完成人参与度、完成人创新度、完成人贡献度为内容的综合评估指标体系共同确定。结论认为,该方法为加快建立以创新价值、业绩、贡献为导向的人才评价体系提供了参考,能够有效解决人才在油气科技创新活动中的经济价值量化问题,对推动高水平科技自立自强有现实意义。

数字出版供应链下区块链投资与版权保护策略

区块链技术的可追溯性、安全性以及不可篡改性可以解决数字内容产品的盗版问题。以此为背景,构建由出版商、销售平台以及消费者构成的数字出版供应链,探讨在传统版权保护和区块链下的版权保护两种版权保护模式中的出版商最优定价和平台最优版权保护强度的决策问题,并比较了供应链绩效。研究发现,区块链下的版权保护模式中平台实施严格的版权保护强度,进而提高正版产品的吸引力,需求上升弥补了传统版权保护下出版商通过降价提高需求造成的利润损失。但是,平台只有在区块链投资成本较低时才愿意投资区块链,无法实现供应链的收益最大化。针对这一问题,通过设计契约提高了平台投资区块链的动机。最后,研究了平台投资区块链对购买正版产品消费者的消费者剩余以及社会福利,发现投资区块链可以提高社会福利,但在一定程度上会损害正版产品的消费者剩余。

数据“利益束”:数据权益制度新论

创设排他性、利己性的数据权利不利于海量数据的高效流通与多元价值的实现,加剧了数据私权化与效用化之间的内生性冲突。在权益区分保护理论框架下,采取数据利益保护进路更具正当性和相对优势。我国宜将数据利益作为数据权益制度的中心,建构人与人之间动态灵活、有机立体的利他性数据“利益束”范式,以有效协调和整合多元主体之间复杂的数据利益关系,并在数据“利益束”范式下,充分利用Web3.0以用户为中心的开放式价值互联网效能,通过点对点的数据利益流通来构建全网络利益格局。我国还应建立合理的激励与收益实现机制,促进所有数据主体共创和共享数据红利,在数据财产行为主义保护模式基础上,建立智能化治理体系来保障数据安全,最终形成中国自主且更能适应数字经济发展规律的新型数据权益制度体系,以此推进我国数字经济的健康发展。

数智技术赋能统战工作发展透视

数智技术与统战工作在价值理念和政治定位等层面具有高度契合性,前者可以满足后者信息化、智能化、精准化、动态化等发展需求,为后者高质量发展提供持续动能。数智技术能有效支撑和服务于统战工作、开拓统战工作数据应用新空间、激发统战工作新活力。当前我国数智统战工作取得了一些进展,但也面临数字化平台和工具应用不足、数据共享和协同体系不完善以及数智化人才短缺和统战干部理念更新不足等问题。因此,未来数智统战应综合运用数智技术,通过构建面向统战对象的大数据智能分析平台、开发数智化统战工作工具、丰富宣传内容和形式,推动统战工作凝聚人心、汇聚力量;通过制定统一的数智统战顶层设计和规划、构建统一开放的统战云平台、完善数智安全保障体系,赋能大统战工作格局的构建;通过推进协商数智化体系构建、建立政协系统数智人才培训与考核机制、加大新技术在协商业务流程中的应用,深化协商民主。

技术进步、反鲍莫尔成本病与制造业占比

根据鲍莫尔的非均衡增长理论,技术进步会导致服务业占比上升,制造业占比下降,这就使得我国既要坚持创新驱动,又要保持制造业占比基本稳定面临理论上的悖论。本文立足我国服务业全要素生产率增速已经高于制造业全要素生产率增速的新变化,指出我国存在着反鲍莫尔成本病现象,即制造业领域而不是服务业领域存在鲍莫尔成本病,这修正了鲍莫尔理论模型,从技术进步角度找到了我国制造业占比下降的根本原因,为创新驱动和保持制造业占比基本稳定同步实现提出了逻辑一致的理论解释。此外,论文借助WIOD数据库2000—2014年17个制造业细分行业数据进行实证研究,结果显示,2011年起制造业TFP增速每提高1%,制造业占比将提高2.3%,TFP水平提升会增强制造业国际竞争力。

企业ESG表现提升劳动收入份额实证研究——基于中国上市公司的经验证据

基于中国上市公司大样本数据检验证实:企业ESG表现提升劳动收入份额源自多种因素的共同作用。笔者依据相关公司治理理论,以2009—2021年中国沪深A股非金融类上市公司的样本有效数据,运用多元线性回归方法实证检验了企业ESG表现与劳动收入份额之间的关系及其变化。检验结果证实:企业ESG表现与劳动收入份额正相关;资金支持、内部控制水平、技术升级中介企业ESG表现与劳动收入份额的相关性;以劳动密集程度和技术密集程度为代表的要素密集程度正向调节企业ESG表现对劳动收入份额的提升,而企业规模和劳动调整成本则发挥反向调节作用。本研究通过将公司内部治理和公司外部性等相关理论原理尝试性地运用于企业ESG表现与劳动收入份额关系的实证研究,从一系列检验诸多相关要素的有机联系上证实了企业ESG表现显著提升劳动收入份额,丰富了关于可持续发展研究领域的现有文献,研究结论有助于为企业以改善ESG表现方式实现高质量发展提供理论依据。

协同创新理论下中国国家实验室建设路径探索——基于美国能源部国家实验室的经验启示

为推进中国国家实验室的开放和协同创新,运用协同创新理论,基于对美国能源部国家实验室协同创新的实践经验分析,结合中国当前面临被西方主要国家技术封锁的严峻形势,探讨协同创新促进中国国家实验室建设的路径。协同创新包含了多方创新主体、共同目标、优势互补和合理分工、复杂的相互作用和整体协同效应等五方面的核心要素,其结构从简单无序布局向高级有序组织变革转变为网络化创新结构,因此要确保协同创新成果实现,需要充分考虑不同主体之间的利益平衡和风险控制等因素。美国能源部国家实验室具有明确的战略目标与使命、充足的财政投入与多元化经费来源、高效的管理运行机制、人员组成多元化的强大科研团队,其发展总体呈现开放化、网络化的对外合作趋势,在协同创新方面形成了强化战略导向和目标聚焦、深化产学研合作、建立高效的协同机制、强化人才培养和团队建设,以及鼓励创新、营造宽容失败的文化氛围等经验举措。借鉴美国经验,深化国际合作和加强内部合作是应对挑战、促进国家实验室建设的两翼。因此,应对当前西方国家技术封锁,中国国家实验室建设须毫不动摇地坚持开放共享与合作交流的理念,强化顶层设计与政策引导,深化产学研用合作,建立高效协同机制,实现多领域协同创新、引领学科交叉创新,并积极融入创新联合体建设,弘扬科学家精神、营造鼓励创新探索的科研文化氛围。
