创新补贴对企业技术并购后研发投入的影响机理研究

技术并购后,企业需要通过研发活动促进技术的吸收和整合,但研发资金却常常受到由于并购导致的未来现金流不确定性的制约。这时,创新补贴可能成为企业弥补资金不足的必要补充。论文以主并企业为A股上市公司的技术并购事件为样本,运用回归分析的方法,探究了创新补贴对并购后研发投入强度的影响机理。结果表明,税收优惠对企业技术并购后的研发投入强度有显著的直接激励效应;财政补贴则是通过降低金融错配对研发投入的抑制作用间接地发挥激励作用。研究结论丰富了吸收能力理论,为政府的创新补贴制度安排以及企业的技术并购决策提供参考。     

东道国人才生态环境对人才根植意愿的影响——人才成长预期的中介效应

基于勒温的场论和ERG理论,遵循"外部环境——心理认知——行为倾向"的逻辑,探讨东道国人才生态环境通过中介变量人才成长预期对于人才根植意愿的影响.研究表明,(1)东道国人才生态环境的四个维度中,经济发展环境、生活环境、文化环境对人才根植意愿具有正向影响;(2)经济发展环境、生活环境、人才政策环境、文化环境对人才成长预期有正向影响;(3)人才成长预期对人才根植意愿有正向影响;(4)人才成长预期在东道国人才生态环境与人才根植意愿间起中介作用;(5)东道国人才生态环境的四个维度及人才成长预期对人才根植意愿影响的总效应从大到小依次为:经济发展环境、文化环境、生活环境、人才政策环境、人才成长预期.     

中学生对体育课好课的期望研究

采用文献资料法、访谈法、问卷调查法、数理统计法等研究方法对莆田市八所中学的460名学生进行调查研究,结果表明：中学生对体育课好课期望依次是教学方法、课堂氛围、师生关系、教师素质、教学环境,学习效果、学习内容、学习目标等,并对各要素有具体的期望。不同学段学生对体育好课的教学目标、教学内容期望上存在显著性差异,不同学校等级在教学内容期望有显著性差异,不同性别学生在指导方式、组织形式期望上有显著性差异。     

Re-examining post-acceptance model of information systems continuance: A revised theoretical model using MASEM approach

This study extends the post-acceptance model of information systems (IS) continuance, which is widely used to explain users’ satisfaction and IS continuance intentions. The extended model includes additional variables such as perceived ease of use (PEOU), attitude, trust, and enjoyment. The proposed model was tested using meta-analytic structural equation modeling (MASEM). The analysis included 1,056 observations on fifteen relationships from 214 independent studies with a combined sample of 84,343. The results confirm the significance of all the relationships proposed in the original model. Furthermore, the findings indicate that PEOU directly influences perceived usefulness, satisfaction, and attitude. Trust and enjoyment both have a positive impact on users’ satisfaction and IS continuance, wherein the effect of enjoyment was higher than trust. post-consumption satisfaction resulted in a favorable attitude toward technology, which further affected IS continuance. From a theoretical perspective, the current study acknowledges the shift in users’ attitude toward technology and emphasizes the hedonic value of IS usage as users report a higher degree of satisfaction toward responsive, easy to use, and enjoyable technologies. Marketers should focus on the enjoyment and gratifications derived from technology to increase potential IS usage.

Seizing control?: The experience capture experiments of Ringley &; Mann

Will the proliferation of devices that provide the continuous archival and retrieval of personal experiences (CARPE) improve control over, access to and the record of collective knowledge as Vannevar Bush once predicted with his futuristic memex? Or is it possible that their increasing ubiquity might pose fundamental risks to humanity, as Donald Norman contemplated in his investigation of an imaginary CARPE device he called the “Teddy”? Through an examination of the webcam experiment of Jenni Ringley and the EyeTap experiments of Steve Mann, this article explores some of the social implications of CARPE. The authors’ central claim is that focussing on notions of individual consent and control in assessing the privacy implications of CARPE while reflective of the individualistic conception of privacy that predominates western thinking, is nevertheless inadequate in terms of recognizing the effect of individual uptake of these kinds of technologies on the level of privacy we are all collectively entitled to expect. The authors urge that future analysis ought to take a broader approach that considers contextual factors affecting user groups and the possible limitations on our collective ability to control the social meanings associated with the subsequent distribution and use of personal images and experiences after they are captured and archived. The authors ultimately recommend an approach that takes into account the collective impact that CARPE technologies will have on privacy and identity formation and highlight aspects of that approach.     

普惠金融对农户宅基地退出行为的影响——基于成都市试点区域401份农户样本

研究普惠金融对农户宅基地退出行为的影响对于推进农村宅基地制度改革和促进乡村振兴具有重要意义。本文基于四川省成都市典型区域401份农户调查数据,采用因子分析法构建了微观层面的农村家庭普惠金融指数,运用Probit模型分析了普惠金融对农户宅基地退出行为的影响,探索了风险预期在影响中的中介作用,并进一步分析其影响的代际差异。结果表明：①普惠金融对农户宅基地退出行为具有显著的正向影响;②普惠金融通过中介变量风险预期间接影响农户宅基地退出行为,风险预期的中介效应占总效应的比例为17%;③新生代农户和老一代农户家庭层面的普惠金融对其宅基地退出行为都有显著的正向影响,但两者之间未发现存在明显的代际差异。本文认为,应基于家庭金融需求和供给双层面加大农村金融支持力度,提升农村普惠金融水平;引导农户形成合理的宅基地退出风险认知,并制定针对性的措施降低农户风险预期;加强政策引导,实现不同代际农户的金融知识共享,推动宅基地有序退出。
