The work presents a robust approach to labor share analysis. The estimate of labor share presents various complexities related to the nature of the data sets to be analyzed. Typically, labor share is evaluated by using discriminant analysis and linear or generalized linear models, that do not take into account the presence of possible outliers. Moreover, the variables to be considered are often characterized by a high dimensional structure. The proposed approach has the objective of improving the estimation of the model using robust multivariate regression techniques and data transformation.  相似文献

苏南乡村地区一直是中国乡村建设的先行区域,特殊的纵横交错的水网结构构成了一个错综复杂的系统,呈现出其他地区不具有的复杂性和生态特殊性。随着城镇的扩张,乡村的发展建设使其水网空间的平衡发展面临极大的挑战。传统单一静态的规划方法逐渐显示出无法适应经济、社会等发展要求的缺陷。苏南乡村地区以水为核心,从水生态系统服务供需关系的视角下探究水网乡村的适应性规划策略更加适应当前的乡村现状和需求。以传统水网乡村空间形态转译为基础,建立水生态系统供需服务评估体系,在评估水生态系统服务供需能力的基础上,分析供需分异模式及供需矛盾。从构建乡村水域空间生态格局、乡村水域空间功能分区规划,以及乡村水域空间多情景预判3个方面,提出苏南水网乡村的适应性规划策略,并为水网乡村的生态实践提出新思路。  相似文献

Circular business models (CBMs) have huge potential to deliver economic, social, and environmental benefits, but CBMs have yet to be implemented widely in industrial settings. One reason is that they are often presented as one-size-fits-all solutions, but this is misplaced because product-specific criteria and company capabilities determine the correct choice and implementation of CBMs. Therefore, the purpose of this paper is to investigate how CBM selection and capability development facilitates the implementation of CBMs. For this purpose, we have adopted a qualitative research approach and undertaken 25 explorative interviews in three large Swedish manufacturing companies. In this paper, a CBM implementation framework consisting of two parts has been developed. The first part addresses the choice of the appropriate CBM based on tactical configurations. The second part provides a capability development path by explicating underlying routines that need to be progressively developed in order to move smoothly to more advanced CBMs.  相似文献

Internet of Medical Things (IoMT) technology remains in early stages of adoption, but advancements and breakthroughs are quickly moving this process forward. There is a critical need for cybersecurity to be a priority in the development of these new tools, alongside design and utility. Given the rapid pace and potential magnitude of the coming advancements in IoMT, if privacy and security risks are neglected, a significant crisis could emerge in the form of more frequent cybersecurity breaches. This article examines the market opportunities and risks associated with IoMT and outlines a plan for proactively mitigating concerns and providing a platform to foster growth, to modify attitudes and behaviors, and to continue to build consumer confidence in the overall health system without sacrificing security.  相似文献

医工交叉是医疗器械持续创新的基础动力,是我国医疗器械产业升级的关键。近年来,我国出台了一系列政策促进科技成果转化,但医工交叉领域具有周期长、多方参与、投资巨大等特点,导致其失败风险高并制约了科技成果转化的效率。本文通过分析医工交叉成果转化中存在的问题,从法律保障的视角提出能够促进科技成果转化的法律制度建议,从科研工作者权益保障、资金托管安全和知识产权收益等角度综合保障转化成果,促进我国医疗器械产业的可持续发展。  相似文献

Online meal delivery platforms (OMDPs), like UberEats, have received more attention since quarantine was established to prevent the spread of COVID-19. The research into antecedents of satisfaction and continuous usage intention for OMDPs, in general, is under researched. The current study compared the antecedents of satisfaction before quarantine to the antecedents during quarantine through the lens of Expectation-Confirmation Theory. Through multiple regression analyses, the researchers found that before quarantine, sharing economy ethos, price-value, food quality, ease of use and confirmation of beliefs had a significant impact on satisfaction while during quarantine, food quality, service speed, ease of use, and confirmation of beliefs were significant. Practical and theoretical implications are discussed.  相似文献

基于1990—2017年行业面板数据,采用超越对数生产函数对服务业各细分行业TFP增长率进行分解和测度,揭示我国服务业内部结构生产率演化进程及其异质性现象,并采用可导性对数方差分解法、VAR协整模型和误差修正模型(VECM)考察TFP及其构成部分对服务业行业发展差距的贡献度,评估其异质性作用于行业发展差距的长短期效应。研究发现,在服务业内部结构演化过程中,TFP、技术进步和技术效率改进呈逐步下降趋势,其中技术进步是推动TFP增长的核心,规模效率改进发展水平一直滞后,配置效率改进在服务业发展初期较为滞后,但水平逐步提升;生产性和生活性服务业行业间TFP及构成部分异质性在演化过程中呈下降趋势,且生活性服务业行业间异质性程度要小于生产性服务业,行业间异质性变化幅度最大的是规模效率改进,技术效率改进异质性波动程度最小;TFP异质性是造成行业间发展差距扩大的主要原因,其中技术效率改进是主导因素,且该效应的发挥只有在长期具有显著性。  相似文献

China has made significant progress in broadband development. As of September 2018, 95% of China's population was covered by 4G networks. However, our estimates show that nearly 30% of China's families did not use broadband that year. This study attempts to investigate the characteristics of China's broadband left-behind families. Overall, consistent with the findings for other countries, families with a lower socioeconomic status are more likely to be broadband non-adopters. In the information society, older, poorer, rural and less educated families are left behind. It is recommended that the Chinese government shift from a top-down investment-driven policy to a user-centered demand-driven policy to address the digital divide.  相似文献

Recently, low-cost airline (LCA) companies have become more attractive. However, emerging digital technologies have transformed the passengers’ profiles. Digital competency has become a crucial matter to capture digital passenger expectations. Hence, the purpose of the study is to introduce a new digital competency evaluation (DCE) model. The proposed model comprises technology transformation & implementation, and also transformation & adaptation management dimensions, with ten criteria and thirty sub-criteria. Criteria weights are calculated using the IVIF AHP method. The results show that the most significant dimension is transformation and adaptation management. The most digitally competent airline is selected through the IVIF VIKOR method. A case study concerning the LCAs is conducted in Turkey to verify the validity of the proposed model.  相似文献
