耐心资本、数字经济与创新效率——基于制造业A股上市公司的经验证据

在创新活动与融资活动联系日益紧密的背景下,资本的特征与属性成为构建“科技-产业-金融”高水平循环的重要因素。理论层面,将具有长期导向和治理作用的股权与债权置于“耐心资本”框架下,分析其对制造业企业创新效率的影响效应与内在机制,提出“耐心”是长期的合作关系与监督治理作用,而“效率”是对创新资源的有效利用,两者能够兼容,即长期导向能够促进效率提升。实证层面,基于制造业A股上市公司2011—2022年数据进行实证检验结果表明:首先,耐心资本有效促进了制造业企业创新效率的提升,其中关系型债权的促进作用更为明显,并且相较于建构创新,耐心资本更能促进高价值、高风险的模块创新。其次,耐心资本能够缓解信息不对称、缓解委托代理冲突,进而促进制造业企业提升创新效率。再次,数字经济在耐心资本促进制造业企业创新效率提升的过程中具有正向的调节作用,其中城市数字经济水平的提高显著增强了关系型债权的促进作用,而企业数字化转型程度的提升更能增强战略型股权的促进作用。最后,耐心资本更能促进市场势力较弱、处于成长期和成熟期的制造业企业提升创新效率。基于研究结论,政策建议如下:积极培育耐心资本,充分发挥耐心资本在降低信息摩擦、优化公司治理方面的优势;全面发展数字经济,为耐心资本参与制造业企业创新治理提供有利的条件和有效的工具;引导不同类型的耐心资本与处在不同发展阶段、面临不同市场结构的制造业企业有效匹配。     

虚拟实践:人类新的实践形式

虚拟实践作为一种新的实践形式,是指主体使用数字化中介手段在虚拟空间进行的实践。实践手段的“数字化”,是虚拟实践突破以往实践的局限,并崛起为一种新型实践形态的基石和标志。虚拟实践不仅促进了人类认识方式、思维方式、生存方式、价值观念的变革,而且也正在强有力地改变着我们的生活和时代。虚实交融将构成未来人类生存和发展的新方式。     

从《史记·五帝本纪》看司马迁的学术研究方法

《五帝本纪》作为《史记》开篇之作,被誉为“中华正史第一本纪”,历来受到学界广泛的关注和高度评价.《史记·五帝本纪》体现出司马迁的“实录”精神和学术研究方法,主要体现为资料收集的广博性、田野调查的广泛性、甄别选材的严谨性、研究思考的深入性等方面.司马迁的“实录”精神和学术研究方法不仅是对历史事实的秉笔直书,更是严谨求实的科学研究方法的体现,对于当今学术研究仍具有深刻的启示作用.     

功在当代,泽被后学——《宋诗话全编》对古代文学研究的学术价值

《宋诗话全编》涵盖了诗论、诗话专著和主要的诗论家及主要的论诗名著,更蒐集到了至今还远未为研究者所知晓的散见于浩瀚载籍中的论诗片言只语,对治古代文学者具有莫大的参考意义和学术价值.一是补阙、正误的重要资料价值.二是为作家、作品研究提供事实支撑（含生平事迹补遗;宋代僧诗和诗僧的材料补充;弥补某些人物关系的重要史事）.三是为文学史上的某些专门问题提供佐证材料.四是艺术风格的品评,文论观点的概括,则更具有直接的理论意义.

民事诉讼中网络聊天证据取证的困境与出路

社交软件在互联网、大数据时代得到了飞速发展,网络聊天证据在民事诉讼中的运用增长迅速。网络聊天证据能否合法有效地收集对最大限度地再现案件真实和实体正义的实现影响甚巨。鉴于网络聊天证据在实务中采信率较低的司法现状,有必要对聊天证据收集的指导原则加以明确,并在此基础上对收集程序和取证主体等配套制度予以完善,赋予网络服务商之法定协助取证义务,以寄望破解当前网络聊天证据原件模糊、取证主体受限、成本高昂之困境。     

Directory of Literary Magazines

Abstract

Libraries face a crossroads when contemplating serials preservation issues. This paper will discuss the ideas presented during “Serials Preservation: at a Crossroads,” a one-day meeting held in March 2005, and sponsored by the North American Serials Interest Group. Binding, off-site storage, preserving e-journals, and vendor efforts, as well as looking at new developments, such as Google Book Search, offer strategies and challenges for preserving serials and expanding avenues of access for users. Many options exist for serials preservation, but libraries must ultimately consider their individual needs and environment to determine the best serials preservation strategy.     

Rethinking Print Periodicals Holdings Retention Policy in Small Academic Libraries

Abstract

Collection development policies in small academic libraries may lack a formal policy statement about print periodical holdings retention. However, there is a need for a distinct policy about print periodicals holdings and their retention. Periodicals collections at academic libraries have been greatly affected by publishers’ decisions to discontinue print journal formats and move to online-only electronic versions. The move from one format to another produces challenges to the retention of an effective print periodicals collection. Given these continuous changes in publication format, it is necessary for academic libraries to rethink their print periodicals holdings retention. This article will present a literature review on and case study of periodicals collection management and explore strategies for developing holdings policies and guidelines for retention. It will argue that collection development policies ought to include a separate policy for the print periodicals collection and that unlike their reputation for being time-consuming and inflexible, periodical retention policies can improve flexibility and guide in decision making, helping to preserve core titles and acquire new titles that support academic programs and the work of the college community.     

Preserving Open Access

Abstract

Libraries have an established track record of preserving the scholarly record, but this stewardship role has generally been exercised over materials the library has purchased or otherwise acquired. With open access publishing, the library’s role in preservation is less certain, as libraries may facilitate access to a wide array of freely accessible materials without ever obtaining any copies. Additionally, the open access landscape includes many small noncommercial publishers with limited resources that may not be able to invest in long term preservation and access. In this column, Courtney McAllister, Electronic Resources Librarian at Lillian Goldman Law Library, Yale University, discusses preservation concerns and strategies for open access publications and how libraries may be affected by unstable or unpredictable long-term access.
