摘要： 城市数字经济发展会促进企业数字技术创新和数字化转型，并提高企业劳动者的数字技能、加快企业劳动资料和劳动对象的数智化升级，从而显著提升企业的新质生产力水平。采用沪深A股上市公司2011—2022年的数据分析发现：城市数字经济发展显著提升了企业新质生产力水平，并对新质劳动者、新质劳动资料、新质劳动对象都具有显著的正向影响（其中，对新质劳动资料的提升作用最大）；城市数字经济发展可以通过提高城市人力资源质量、提升企业创新效率、拓展企业知识网络3条路径来促进企业新质生产力发展；城市数字经济发展显著提升了非国有企业的新质生产力水平，但对国有企业新质生产力的影响不显著；城市数字经济发展对高新技术行业和市场竞争程度较强行业企业新质生产力水平的提升作用更强。因此，应加快城市数字经济发展，充分发挥其对企业新质生产力发展的促进作用，并持续推进经济体制改革，促进高新技术企业高质量发展，以市场力量驱动企业新质生产力的整体跃升。

摘要： 以邻为壑的贸易保护主义近年来呈泛滥势头，在严重损害企业进出口收益的同时是否会挫伤对外投资热情是国际商务研究讨论的热点。现有文献认为贸易壁垒既会加剧对外投资难度并侵蚀投资收益，也会增强对外投资替代进出口的意愿。提出弥合争议的焦点在于考虑对外投资类型和情境变量。基于行业层面的贸易壁垒强度与中国高科技制造企业海外研发的匹配数据，研究发现贸易壁垒会加速企业海外研发，同时提升海外研发的规模强度和地域广度。企业利用海外研发替代关键技术引进和出口市场扩张的进出口替代效应是贸易壁垒影响海外研发的内在机制。研究还发现，高管的政治关联与海外任职经历显著增强了贸易壁垒对海外研发的正向影响，但调节作用仅在母国与研发东道国达成较高的政治共识时成立。研究结论不仅丰富了国际商务理论关于科技地缘政治风险对企业战略选择和行为的影响研究，同时对贸易壁垒冲击下身陷逆境的企业如何突围具有启示意义。

摘要： The present thesis is conceived as a commentary to the attached publications and represents several years of study of the fossil woods from the volcanic rocks of the České středohoří and Doupovské hory Mts. (Paleogene, Czech Republic). A brief introduction to the subject is followed by an overview of the used methods, a short geological setting and the history of fossil wood research in the study area. The results are presented by individual localities, where the description of the locality is followed by a systematic evaluation of the fossil woods. In the studied fossil wood material, there are 3 conifers from 2 families: Glyptostroboxylon rudolphii, Taxodioxylon gypsaceum (both Cupressaceae s.l.) and Pinuxylon parryoides (Pinaceae) and 17 angiosperms from 9 families: Cinnamomoxylon seemanianum (Lauraceae), Platanoxylon bohemicum, Platanoxylon sp. (both Platanaceae), Ulmoxylon marchesonii, Ulmoxylon cf. kersonianum, ?Ulmoxylon sp. (all Ulmaceae), Quercoxylon böckhianum, Castanoxylon bavaricum, Lithocarpoxylon sp. (all Fagaceae), Eucaryoxylon crystallophorum (Juglandaceae), Alnus tschemrylica (Betulaceae), Grewioxylon ortenburgense, cf. Grewioxylon ortenburgense (both Malvaceae s.l.), Paradiospyroxylon kvacekii (Ebenaceae), Fraxinoxylon cf. prambachense (Oleaceae) and two indeterminable samples...

摘要： 以G60科创走廊建设为准自然实验，利用2012—2021年长三角41个城市民营上市公司数据构建多期双重差分模型，研究区域科创一体化对民营企业嵌入创新网络的影响及其机制。研究结果表明：区域科创一体化能够促进民营企业在省内和省外创新网络中的结构嵌入和关系嵌入。机制检验表明：区域科创一体化既能通过强化新型基础设施建设为民营企业嵌入创新网络提供机会，又能通过扩大创新市场需求和鼓励创新市场竞争为民营企业嵌入创新网络激发动机，还能通过细化创新专业化分工和优化创新要素配置结构为民营企业嵌入创新网络提升能力。进一步研究发现，企业合作文化与社会信任水平、企业专利诉讼风险与地区知识侵权风险对区域科创一体化的政策效应分别具有正向和负向调节效应。研究结论有助于民营企业理解和把握区域科创一体化的潜在价值和协同机会，并为民营企业有效融入并深度嵌入区域创新网络提供了理论与实践启示。

摘要： The most important indicators used by teachers when teaching students in elementary schools are related to pedagogical competence as well as basic activities for mastering basic teaching skills. The task of teachers is not only to convey or decide knowledge to children at school, but teachers also have the task of developing the personalities of the children they educate in an integrated manner. To become a professional teacher, you need testable indicators that can show your ability to teach students in elementary schools during the school year. Teachers develop children’s mental attitudes, develop children’s conscience, so that children are sensitive to issues of humanity and human dignity, and also develop children’s life skills in society. This type of research uses a qualitative descriptive approach with a survey method that aims to describe indicators of pedagogical competence, indicators of professional teacher competence, and determine the needs of teachers in developing their pedagogical competence. This research discusses indicators of pedagogical competence among professional teachers and describes the general situation of elementary school teachers’ needs in an effort to improve pedagogical competence.

摘要： 以2009—2022年沪深A股上市企业为研究对象，分析保险资金持股对企业绿色创新的影响。结果表明：保险资金持股对企业绿色管理创新和绿色技术创新有显著促进作用，且在制造业、非国有及小规模企业中表现更强。长期持股型和投资型保险资金持股主要促进企业绿色技术创新，短期持股型保险资金持股仅会促进企业绿色管理创新，保障型保险资金持股对企业绿色创新没有显著影响。企业ESG表现在保险资金持股对绿色创新的影响中发挥部分中介作用，且在购买D&O保险的企业中更明显，其作用路径是促进企业执行环保政策、采取更加环保的措施、增强社会责任以及降低财务风险和技术创新风险。

摘要： Hypericum perforatum, also known as St. John’s Wort, pericon, or yellow grass, is known for its antidepressant potential. It could represent a natural alternative to current pharmacological antidepressant treatments, which have a high incidence of side effects in patients and therefore lead to early dropouts. Through a bibliographic revision of clinical trials and information collected from scientific articles during the first period of 2020, we aimed to evaluate whether its administration could be beneficial in the treatment of mild-to-moderate depression, with fewer side effects compared to synthetic drugs. Among the main components, hypericin and hyperforin have been related to the observed antidepressant activity; therefore, their possible mechanism of action was reviewed and highlighted. Furthermore, patients receiving Hypericum extracts were less likely to withdraw from studies because of adverse effects compared to those receiving older standard antidepressants. This review aims to provide suggestions for an alternative treatment of mild-to-moderate depression disorder under the supervision of a medical doctor, since, although it appears to be a potentially efficient treatment with a low presence of adverse effects in comparison to synthetic antidepressants, it might also interact with other medications and lead to therapeutic failures if misused for self-medication.

摘要： 工业4.0下的数字化转型具有资源密集性特征，中小制造企业作为主力军需要以资源撬动机会来应对复杂性、未知性和风险性，机会-资源一体化如何助力中小制造企业实现数字化转型具有重要研究意义。本文运用探索性单案例研究发现：（1）数字化转型过程中，企业主导逻辑由数智化产品主导逻辑向多元化服务主导逻辑再向场景化价值主导逻辑转变，动态引导机会-资源一体化演化。（2）企业通过机会发现-资源拼凑一体化助力实现单点优化；通过机会创造-资源编排一体化助力实现多点集成；通过机会共创-资源协奏一体化助力实现生态协同。（3）数字化转型的逐步深入能够丰富企业资源池和拓宽数字机会集，促进机会-资源一体化升级，二者呈现迭代循环、螺旋上升的形态。本文有助于填补现有关于数字化情境下机会-资源一体化研究的理论缺口，并对中小制造企业在数字化转型过程中实现资源和机会协同的管理实践具有参考价值。
