Multinational Companies,Technology Spillovers and Plant Survival*

How does the presence of multinational companies affect plant survival in the host country? We postulate that multinational companies can impact positively on plant survival through technology spillovers. We examine the nature of the effect of multinationals using a Cox proportional hazard model, which we estimate using plant‐level data for Irish manufacturing industries. Our results show that the presence of multinationals has a life‐enhancing effect only on indigenous plants in high‐tech industries, suggesting the presence of technology spillovers. In contrast, multinationals compete with each other in low‐tech sectors in the host country.     

企业ESG 履责的绿色生产力效应研究——基于绿色技术创新视角

论文选取2011-2020 年沪深A 股上市公司为研究样本,基于绿色技术创新视角,实证研究了企业ESG 履责的绿色生产力效应。研究发现,ESG 履责显著促进了企业绿色技术创新水平;机制检验发现,企业ESG 履责主要通过缓解财务约束,提升企业声誉,以及提高企业信息披露质量,促进绿色技术创新水平的提升;进一步基于“宏观——中观——微观”的多维异质性检验显示,当企业所处环境规制压力较高、所在行业竞争压力较大、以及企业人力资源基础较好时,ESG 对绿色技术创新的促进效应更为凸显。论文研究对新形势下构建绿色生产力体系、助力实现新质生产力发展提供有益启示。     

数字技术融合对企业创新数量与质量的影响

以268家医疗装备企业为研究对象,从Himmpat专利数据库获取2002—2022年的15 446条专利数据,构建“数字-医疗”技术融合网络,基于量与质的视角实证分析数字技术融合对企业创新绩效的影响。采用负二项固定效应回归模型进行实证研究。结果表明,互补性数字技术融合和替代性数字技术融合均对企业创新质量和数量具有正向影响,融合波动性负向调节上述关系。     

我国对外技术依存度的测算及浅析

建设创新型国家成为国家的战略目标,而对外技术依存度的高低成为衡量创新型国家的一个重要指标。针对当前对外技术依存度算法的不足,提出一种全新的测算方法,从技术依存度的内涵出发系统地构造衡量指标和计量模型,运用因子分析方法对我国对外技术依存度进行了测算,并简析其原因。结果显示,中国的对外技术依存度在快速提高,并处于很高的水平,表明我国的技术对外依赖程度非常高,经济技术发展受制于人,我国亟需加强自主创新。     

建筑工程技术管理模式研究

建筑工程技术管理水平是影响建筑企业经营管理、建筑企业总体效益的重要决定因素.随着社会的不断进步,中国经济得到突飞猛进的发展,国内建筑业也随之风生水起,前景一片光明,但是在此同时建筑工程技术管理中依然存在许多问题.本文主要从建筑工程管理模式中存在的问题出发,提出一些有针对性的解决方案,并在此基础上进一步完善建筑工程的技术管理模式,从而促进建筑工程质量的进一步提高.     

Bertrand竞争条件下质量提高型创新技术最优许可研究

基于Bertrand双寡头竞争模型,建立高质量产品生产企业与低质量产品生产企业间的创新技术许可模型,比较了固定费用、提成以及两部制三种许可方式下的许可决策。研究结果表明：（1）创新技术拥有企业不会采用固定费用许可方式进行技术转让;（2）提成许可方式下：当产品质量差异程度较小,且创新技术程度较低时,创新企业选择许可,否则不许可;当产品质量差异程度较大时,创新企业愿意进行提成许可。

How do customers meet their needs in in-store and online fashion shopping? A comparative study based on the jobs-to-be-done theory

Understanding customer needs is key for fashion retailers to stay competitive and innovative. Surprisingly, however, extant literature mainly explores customer needs in terms of a garment and its attributes rather than viewing shopping as a problem-solving process to meet customer needs. Moreover, these studies fail to address how customers meet their needs in-store (ISFR) and online fashion retailing (OFR). To fill this research gap, we empirically investigate customers' personal and social needs and how they can be met through the jobs-to-be-done theory. Findings reveal that, beyond the purchase of a garment, customer needs can be fulfilled through different ways, such as smart technology or a person's high interaction with social others in ISFR and the online shop experience or a social linkage without social interaction in OFR. Additionally, our findings offer potential service innovations for fashion retailing managers.     

Life after school: How science and technology teachers construe capability

Science and technology teachers create microcosms of the world beyond school as responses to perceived student needs. The focus of these microcosms for both science and technology classrooms was less of a concern for work preparation than for the development of social and intellectual habits. All of the teachers have strong views of the virtues of civil daily life and what it might take for their students to live the good life. The practical capability the teachers want their students to have transcends the instrumental to become moral.     

先进制造系统技术创新优势无形效益评价

技术创新优势指先进制造系统由于采用了先进的制造技术而优于传统制造系统的优势。技术创新优势的无形效益主要表现在系统稳定性、技术先进性以及学习曲线效益。建立了技术创新优势评价模型,并利用了模糊数学的方法,实现了技术创新优势效益的货币化。
