文章结合数字经济的内涵和外延,分别从数字基础设施、数字产业化、产业数字化等方面构建了数字经济发展水平量化指标体系,基于熵值法测度了中国2010—2018年数字经济发展趋势,并建立灰色预测模型对2019—2028年的数字经济发展走向进行预测。研究结果表明:2010—2018年,中国数字经济发展水平增长了4.4倍,年均增速达到50%,2019—2028年,中国数字经济发展水平增速将不断提高,预计2028年数字经济发展水平将是2018年的5倍。因此,我国要进一步推动新型数字经济基础设施建设,加快传统产业的数字化转型,积极发展电信业等数字产业,以保障我国数字经济快速发展。 相似文献

Poor quality of care may have a detrimental effect on access and take-up and can become a serious barrier to the universality of health services. This consideration is of particular interest in view of the fact that health systems in many countries must address a growing public-sector deficit and respond to increasing pressures due to COVID-19 and aging population, among other factors. In line with a rapidly emerging literature, we focus on patient satisfaction as a proxy for quality of health care. Drawing on rich longitudinal and cross-sectional data for Spain and multilevel estimation techniques, we show that in addition to individual level differences, policy levers (such as public health spending and the patient-doctor ratio, in particular) exert a considerable influence on the quality of a health care system. Our results suggest that policymakers seeking to enhance the quality of care should be cautious when compromising the level of health resources, and in particular, health personnel, as a response to economic downturns in a sector that traditionally had insufficient human resources in many countries, which have become even more evident in the light of the current health crisis. Additionally, we provide evidence that the increasing reliance on the private health sector may be indicative of inefficiencies in the public system and/or the existence of features of private insurance which are deemed important by patients. 相似文献

激励在复杂产品供应链中对主供协同合作关系及质量控制发挥了重要作用。本文研究基于主制造商在复杂产品生产研发前按照客户要求形成的质量意识的激励策略是否可以实现复杂产品质量控制问题。考虑具有质量意识的主制造商和其系统供应商组成的两级供应链,建立以主制造商为领导者的Stackelberg博弈模型,分别讨论无激励和存在激励时的主供生产最优决策。基于激励方式的不同,将激励策略分为根据供应商产品质量水平激励以及根据主制造商质量意识水平激励两种方式。研究结果表明激励是供应商加强协同合作、改进产品质量的内在动力,主制造商根据质量意识激励供应商可以进一步促使双方协同合作,提高产品质量,使双方获得更高的利润从而实现供应链整体利润最大化。此外用灵敏度分析发现提高主制造商质量意识水平可以增加双方协同合作努力程度,有效提升产品质量水平并实现帕累托改进。 相似文献

针对如何正确引导 GHG 排放的气候反馈经济损失下导向性技术创新,以实现长期的绿色增长这一问题,基于 DICE 模型,重构导向性技术创新不同的动力要素及其与气候变化之间的内生关系,建立了可体现绿色增长“均衡性”、“包容性”和“可持续性”的非线性最优控制模型。数值仿真结果显示: 气候反馈经济损失不容小觑; 偏于生产的绿色技术创新导向下社会生产力强劲但存在气候环境恶化风险,偏于减排的绿色技术创新导向下气候反馈经济损失小但存在增长动力匮乏风险,二者虽均可实现长期的绿色增长,但中性的绿色技术创新导向会更稳妥; 偏于生产的绿色技术创新导向下人均消费变化率在短期内会显著提升。 相似文献

通过对太湖地区传统水利生态的一些基本规律的认识,诸如太湖与三江一体化,活水周流等,分析了水生态文明结构的长期稳定性,及其水文生态结构的长期承传性。新时代下基本生态水文结构所形成的水环境问题,仍可以从古代的水利生态结构中寻求解决之路。许多现代水利工程所产生的问题,仍可以从古代的经验中得到解决。水污染的解决,景观水面的增加,古代的活水周流经验可以直接应用。传统文人所重视的水文景观,需要在现代社会承传并推广。 相似文献

In this article I examine the lack of self‐care regimes for women working in the non‐profit/non‐governmental sector. While I draw on ethnographic research conducted in the Malaysian context of women's organizations, the issue of self‐care for activists and feminist activists is a global one that crosses borders and boundaries. I explore the gendered nature of care and care professions to demonstrate how women are predominantly affected in these working environments. To date, there has been little scholarship on self‐care and care in non‐profit/non‐governmental working environments. Using interviews with women working in the sector, I argue that women's emotional, mental and physical health comes at a cost in these hectic workplaces. This article contributes to the literature on gender, work and care in women's organizations by taking seriously women's concerns working in these spaces, where they experience self‐neglect and institutional barriers in care regimes. 相似文献

This paper provides the first systematic look into the existing research on performance management (PM) practices employed in lean manufacturing organisations (LMOs). It adopts a systematic review method to examine the evidence generated in the period 2004 – 2015 and uses a comprehensive PM framework to synthesise the findings. The results suggest that PM practices that have the most prominent role in LMOs are those that, firstly, are located closest to front-line actions and, secondly, explicitly address operational realities. This calls into question the primacy of accounting-driven controls in LMOs, suggesting that operational controls may be more effective than top-down accounting-based PM practices. The results also confirm the bias towards operational-level issues but suggest that LMOs may integrate the operational and the strategic levels by using PM practices that drive organisational learning through employee involvement and engagement. 相似文献

This article discusses the socio-cultural dynamics that interact with ethno-racial identity experiencing in a previously under-researched group. A qualitative interdisciplinary study with 40 Native American academics from 28 mainstream universities across the U.S. served as a case example with findings that contrasted with historically influential theoretical frameworks postulating identity confusion and conflicts at the intersection of one’s mainstream education and profession versus one’s ethno-racial community grounding. Instead of feeling pressure to identify with only one worldview, the contextual, dynamic identities associated with the inclusive and flexible self-concept of tribal participants allowed them to in turn take advantage of two divergent cultural meaning systems pertaining to their distinct socio-cultural contexts. These shifts were experienced as not endogenous but rather exogenous variables, which did not cause the historically theorized issues. Participants felt their tribal identities instead facilitated meaningful integration of the existing incongruences, which resulted in unexpectedly resilient subjective experiencing. 相似文献

People who divorce experience a number of negative impacts, and yet divorce also offers opportunities for growth and transformation. This qualitative study of older adult women offers the possibility that divorce may be sexually empowering, especially for women, based on in-depth interviewing of women who had gone through one or more divorces. Detailed examples of the experiences of fourteen women with divorce and sexual expression are offered, focusing on in which situations divorce might be empowering and how it could contribute to sexual exploration and satisfaction. Overall, for the fourteen women in the study who had experienced divorce, the quality of sex in the marriage impacted the quality of sexual expression after the divorce. Also, these findings supported the idea of transformational learning through divorce, and expand divorce-stress-adjustment and transformational learning perspectives to apply more specifically to sexual expression. Understanding possible impacts of divorce over the lifespan, including strengths-based aspects, is important for social workers as the population they serve ages. 相似文献
