基于对象—过程—主体分析方法的区域低碳交通评价研究

推动节能减排与促进低碳发展已经成为我国发展的重要议题,建立与低碳交通概念相适应的评价体系,对于我国低碳建设具有重要意义。运用对象—过程—主体分析方法,在对象维度考察能源消耗与碳排放;过程维度考察输入端、循环端和输出端;主体维度考察政府、交通企业和公众的共同行为。由此构建"对象—过程"维度和"对象—主体"维度2个一级指标13个子指标的区域低碳交通评价指标体系。在此基础上,结合模糊数学方法与理想解法,建立区域低碳交通评价方法。以江苏2017年交通发展为例开展评价分析,形成区域低碳交通政策矩阵,以期为低碳交通管理提供参考。     

银行信息系统外包及其风险管理研究——以C银行风险管理为例

银行投入了大量的资金进行IT建设,优化业务流程,提高服务效率,其普遍采用的方法是外包。但是,在开发和外包过程中,由于缺乏对项目的风险管理,问题不断产生,可能直接影响项目的上线。银行IT外包风险管理的一个有效手段就是对该风险的预先防范,对每个风险事件的风险影响程度、风险产生概率进行评估,为IT外包风险管理提供科学的依据,提高风险管理的效率和质量。本文详细地辨识了银行IT外包风险的风险源,并以C银行IT外包为背景,运用Borda方法对各种风险进行了评估。在此基础上,分析了风险的控制和防范策略,为银行业IT外包风险管理提供了一个实用而有效的菅理范式。

我国第三方支付沉淀资金监管的博弈论分析

国内电子商务的迅猛发展导致第三方支付业务交易量增加显著。它在给人们带来极大便利的同时,也引起人们对相应第三方支付行业中大笔沉淀资金的挪用及账户中产生利息的归宿问题的关注。近期央行采取颁发营业牌照的措施以抬高第三方支付业务准入门槛,进一步引发人们对第三方支付业务中存在的诸多问题的讨论。本文通过分析沉淀资金的形成、积累及利用和相应利息的配置,借用博弈分析方法对支付矩阵进行推导,在加强第三方支付行业沉淀资金监管的基础上,针对性提出央行应给予第三方支付机构适度利用沉淀资金的权利、沉淀资金利息多样化配置、构建评价体系、促进信息公开化的观点。     

Cost–consequence analysis of a hemostatic matrix alone or in combination for spine surgery patients

Background: A five-year retrospective database analysis comparing the use of Floseal¹ flowable topical hemostat alone (F) and in combination with gelatin/thrombin (F?+?G/T) to achieve hemostasis and control surgical bleeding showed higher resource utilization for F?+?G/T cases relative to F matched pairs during spinal surgery. Lower resource use in the F group was characterized by shorter hospital length of stay and surgical time as well as fewer blood transfusions and less hemostat agent used per surgery.

Objective: To evaluate the cost–consequence of using F compared to F?+?G/T in minor, major and severe spinal surgery from the US hospital perspective.

Methods: A cost–consequence model was developed using the US hospital perspective. Model inputs include clinical inputs from the literature, cost inputs (hemostatic matrices, blood product transfusion, hospital stay and operating room time) from the literature, and an analysis of annual spine surgery volume (minor, major and severe) using the 2012 National Inpatient Sample (NIS) database. Costs are reported in 2017?US dollars. One-way and probabilistic sensitivity analyses address sources of variability in the results.

Results: A medium-volume hospital (130 spine surgeries per year) using F versus F?+?G/T for spine surgeries is expected to require 85 less hours of surgical time, 58 fewer hospital days and 7 fewer blood transfusions in addition to hemostat volume savings (F: 1?mL, thrombin: 1994?mL). The cost savings associated with the hospital resources for a medium-volume hospital are expected to be $317,959 (surgical hours?=?$154,746, hospital days?=?$125,237, blood transfusions?=?$19,023, hemostatic agents?=?$18,953) or $2445 per spine surgery.

Conclusions: The use of F versus F?+?G/T could lead to annual cost savings for US hospitals performing a low to high volume of spinal surgeries per year.     

An Evaluation of Institutional Matrices Theory Which Was Designed to Illustrate Differences Between Russian and Western Political Economies

This article is devoted to the evaluation of the institutional matrices theory (IMT), which was designed to illustrate the differences between Russian and Western political economic systems. IMT has no matrix, and it is an ideological declaration rather than a theory. It is a set of assertions and assumptions that are adopted without evidence, and then hypostatized to be Russian and Western socioeconomic systems. IMT literature claims to utilize the reciprocity, redistribution, and exchange model of Karl Polanyi (1944 Polanyi, Karl. The Great Transformation. New York, NY: Rinehart &; Company, 1944. [Google Scholar], 1957 Polanyi, Karl. “The Economy as Instituted Process.” In Trade and Market in the Early Empires: Economies in History and Theory, edited by Karl Polanyi, Conrad M. Arensberg and Harry W. Pearson, pp. 239-270. New York, NY: Free Press, 1957. [Google Scholar]). However, IMT suffers from a number of assumptive and methodological problems in its application, the first of which consists of the complete exclusion of reciprocity from consideration. The first section of the article is an explanation of problems with IMT, and the second section demonstrates some particulars of the IMT problems with a real-world social fabric matrix from a Western nation.

人民币实际汇率升值对中国经济各产业的影响——基于可计算一般均衡模型(CGE)的分析

研究构建了一个可计算一般均衡模型(CGE)以量化估算人民币实际汇率升值对中国经济各部门的影响。根据最新的中国2005年投入产出表编制了中国2005年社会核算矩阵作为CGE模型的基础数据集。研究表明:除服务业、建筑业外,人民币实际汇率升值使大部分产业产出下降,升值的财富效应导致国内购买力增强,服务业、建筑业产出随之增加;升值使农业部门的农业劳动力需求减少,服务业、建筑业的劳动力需求增加,大部分非农行业的劳动力需求也都趋于减少。
