Measuring the size of global logistics expenditure is a difficult task. What is an estimate of logistics expenditures for the global economy? The objective of this research is to answer this question. Using neural networks, an artificial intelligence methodology, logistics expenditures have been estimated at the country level. There are two main contributions from this research. The first is an update of previous estimates of global logistics expenditures. The second is continuous improvement of the estimation method, including information quality and availability as well as mathematical model refinement.  相似文献

The objective of this research was to estimate logistic expenditure for the global economy. An Artificial Neural Network was used to generate national estimates. The estimation set constitutes 24 countries representing approximately 75% of the global Gross Domestic Product. The model utilizes variables that capture economic activity, transportation activity, income level, country size, and geographic location. This research updates previous estimates and represents continuous improvement of the estimation method, including new input variables, better information quality, mathematical model refinement, and methods of model validation.  相似文献

医疗保险与消费:来自新型农村合作医疗的证据   总被引:12,自引:3,他引:12  
本文利用农村引入新型农村合作医疗这一政策变化来研究医疗保险的获得对农村居民消费的影响。结果表明,新农合使得非医疗支出类的家庭消费增加了约5.6个百分点。这一正向作用随医疗保险保障水平的提高而增强,而且在没有医疗支出的家庭中仍然存在。同时,新农合对消费的正向影响在收入较低或健康状况较差的家庭中更强。这些结果都与医疗保险减少了预防性储蓄的假说相一致。另外本文发现,新农合的效果随农户在这个项目中的经历而变化。实际上只有在那些有村民获得保险补偿的村子,保险对消费的正向影响才显著,而且在这些村子中,新农合对新加入农户的消费的影响明显小于对参合一年以上农户的消费的影响。  相似文献

本文考察了现阶段我国财政收入与财政支出政策相互间结构关系特征。我国长期以来采取扩张性的财政支出政策,同时财政收入政策相对从紧。财政收入绝对增长的同时,占GDP比重持续上升。在采取了一系列减税政策的同时,企业赋税压力并未减弱。地方政府普遍财政支出大于一般预算收入,中央转移支付力度不断加大,地方政府本身平衡预算的能力和责任在制度上缺乏可能等等,都构成我国财政政策效应的特点,都需要深入讨论。  相似文献

中国医疗服务市场中的信息不对称程度测算   总被引:11,自引:0,他引:11  
本文构建了一个医疗服务市场上信息不对称程度的测度模型,并基于"中国健康与营养调查"(CHNS)中微观个体调查数据,对医疗服务市场上医患双方的信息程度及其对最终的医疗服务价格的影响效应进行了实证测度。研究结果表明:(1)医患双方所掌握的信息因素对最终医疗服务价格的形成具有重要影响,同时医生相对于患者掌握着更多的信息并具有更强的议价能力;(2)几乎所有的患者都将被迫接受一个高于公正基准价格的价格,平均而言达成的医疗服务价格相对于公正的基准价格要高出26.61%;(3)年度效应分析发现,1989—2006年,各年度的医疗服务市场价格大致都高于公正基准价格26%左右,换言之,改革开放以来中国的医疗服务体制改革,并未有效起到解决"看病难、看病贵"的作用;(4)患者在城乡因素、医疗保险、工作状况、年龄以及受教育程度等因素上的异质性,对医患双方最终价格的作用是有限的。本文的政策含义是:强调通过引进竞争,强化市场机制在医疗服务市场中调节作用的改革思路,是否适合中国值得反思。解决现实中普遍存在的医疗服务价格虚高问题,回归医疗服务的公益性,需要政府更多地参与其中,并有效发挥价格规制、市场监管以及外部性矫正等功能。  相似文献

现行职工基本医疗保险制度规定退休人员不缴费,可能引发两个问题:一是影响社会保险公平性;二是在人口老龄化趋势下基金支付压力过大。本文认为设置职工基本医疗保险最低缴费年限是社会保险公平性和共济性的体现,有助于明晰参保人的权利与义务。也是缓解基本医疗保险“系统老龄化”的重要措施。文章基于基金长期平衡的思想,通过引入“应缴费年限”和“可缴费年限”两个中间变量构建了普遍适用于任一统筹地区的最低缴费年限计算模型,并运用所构建模型进行实例分析和提出政策建议。  相似文献

逐步在我国建立公平有效的基本医疗保障制度是当前医疗体制改革的首要目标.几年来,尽管我国在这方面取得了一定成绩,但为了防范广泛存在的道德风险,政府的不恰当措施却导致我国在医疗保险体制上出现了诸如门诊负担沉重、报销水平偏低、医疗成本控制过严和医疗保险基金挪用等严重问题.如何解决这些问题是本文研究的关键.我们从分析基本医疗保险的性质出发,集中论述了由共用资源和委托代理关系所引发的道德风险以及政府所面临的两难困境.最后,我们提出了相应的政策建议:政府应在放宽对参保人和医疗机构限制的基础上,通过构建合理的激励与监督机制来健全基本医疗保险体系.  相似文献

Objective:

To investigate the evolving use and expected impact of pay-for-performance (P4P) and risk-based provider reimbursement on patient access to innovative medical technology.

Methods:

Structured interviews with leading private payers representing over 110 million commercially-insured lives exploring current and planned use of P4P provider payment models, evidence requirements for technology assessment and new technology coverage, and the evolving relationship between the two topics.

Results:

Respondents reported rapid increases in the use of P4P and risk-sharing programs, with roughly half of commercial lives affected 3 years ago, just under two-thirds today, and an expected three-quarters in 3 years. All reported well-established systems for evaluating new technology coverage. Five of nine reported becoming more selective in the past 3 years in approving new technologies; four anticipated that in the next 3 years there will be a higher evidence requirement for new technology access. Similarly, four expected it will become more difficult for clinically appropriate but costly technologies to gain coverage. All reported planning to rely more on these types of provider payment incentives to control costs, but didn’t see them as a substitute for payer technology reviews and coverage limitations; they each have a role to play.

Limitations:

Interviews limited to nine leading payers with models in place; self-reported data.

Conclusion:

Likely implications include a more uncertain payment environment for providers, and indirectly for innovative medical technology and future investment, greater reliance on quality and financial metrics, and increased evidence requirements for favorable coverage and utilization decisions. Increasing provider financial risk may challenge the traditional technology adoption paradigm, where payers assumed a ‘gatekeeping’ role and providers a countervailing patient advocacy role with regard to access to new technology. Increased provider financial risk may result in an additional hurdle to the adoption of new technology, rather than substitution of provider- for payer-based gatekeeping.  相似文献

Aims: To compute the financial and mortality impact of InSight, an algorithm-driven biomarker, which forecasts the onset of sepsis with minimal use of electronic health record data.

Methods: This study compares InSight with existing sepsis screening tools and computes the differential life and cost savings associated with its use in the inpatient setting. To do so, mortality reduction is obtained from an increase in the number of sepsis cases correctly identified by InSight. Early sepsis detection by InSight is also associated with a reduction in length-of-stay, from which cost savings are directly computed.

Results: InSight identifies more true positive cases of severe sepsis, with fewer false alarms, than comparable methods. For an individual ICU with 50 beds, for example, it is determined that InSight annually saves 75 additional lives and reduces sepsis-related costs by $560,000.

Limitations: InSight performance results are derived from analysis of a single-center cohort. Mortality reduction results rely on a simplified use case, which fixes prediction times at 0, 1, and 2?h before sepsis onset, likely leading to under-estimates of lives saved. The corresponding cost reduction numbers are based on national averages for daily patient length-of-stay cost.

Conclusions: InSight has the potential to reduce sepsis-related deaths and to lead to substantial cost savings for healthcare facilities.  相似文献
