投入产出式资金流量表和资金关联模型

本文设计并推算编制了中国投入产出式资金流量表,并借鉴投入产出分析模型构建了资金关联模型。文中首先归纳整理了国内外相关研究,在此基础上设计编制了针对我国资金流量核算特点的,涵盖金融交易和实物交易体现完整的资金流动内容的三种投入产出式资金流量表。三种表分别反映金融交易形成的部门间资金关联关系、实物交易形成的部门间资金关联关系、金融交易和实物交易等各交易项目之间的资金关联关系。本文构建的资金关联模型,能够实际应用于经济系统中资金关联关系的实证分析和研究。     

基于多阶段超效率DEA模型的银行业效率研究

国内现有的银行DEA效率研究文献中基本存在三个问题,一是不同的投入产出变量选择标准导致各研究结果之间缺乏比较的基准,二是单一的效率指标无法反映银行的金融服务特征,三是传统的DEA效率无法对有效率银行进行再排序。本文通过对银行综合效率的合理分解构建了多阶段超效率DEA模型,可以较好地解决这些问题。同时运用该模型对中国银行业效率进行了实证检验,得到比较有价值的研究结论。     

Aggregation (in-)variance of shared responsibility: A case study of Australia

This article deals with shared producer and consumer responsibility, a concept aimed at overcoming the non-additivity, or double-counting problem in corporate and national sustainability reporting. It reports on the potentially distorting effects that varying sector and business classifications could have on the apportioning of emissions (or other sustainability measures) amongst producers and consumers in an economy. A quantitative (in-)variance analysis is provided which shows that shared-responsibility formulations are remarkably stable under extreme aggregation of the underlying input-output data. Value-added pegging of the sharing parameters generally reduces variance in comparison to constant sharing parameters. These results help in substantiating the robustness of the shared-responsibility concept, a feature which is critically important if shared responsibility were to become corporate and national reporting practice.     

Evaluating the effects of embodied energy in international trade on ecological footprint in China

Based on sub-sectoral level of economy and detailed traded items, embodied energy (EE) in international trade flow in China is estimated during 1996-2004, and the effects of EE on sustainability are quantified by using one of the most popular indicators—Ecological footprint (EF). A framework of EF method, which is more relevant to realism of specific country, is proposed in this paper. The results show that China is a net importer of EE during the period covered by this study except for the year from 1997 to 1999. Imported, Exported and Net imported EE tends to increase sharply along time series. Net imported energy would increase 38% and energy consumption would increase 2.8% in 2004 if EE were taken into account. Footprint_energy is the most important part of EF components and is significantly affected by EE, and the effects of EE on EF are similar to that of Footprint_energy. Footprint_energy, EF and ecological deficit of 2004 will be underestimated about 2.92%, 1.36%, 2.83%, res pectively, if EE is not taken into the national energy budget. Continuous increase of EF and ecological deficit along time series indicates that China is moving away from sustainability. 1.47 times Chinese territories are accurately occupied by China in 1996 while 1.71 times in 2004. Obviously unsustainability procedure of China is accelerated by EE. The contribution of EE to EF and ecological deficit is small in absolute terms expressed in per capita, but the effects on whole nation are huge if the population of China multiplies them. To curb the increase of EF and ecological deficit and to achieve the goal of sustainability, some policy and measures are also proposed.

VFP中Grid表格控件的使用技巧

各类控件在可视化程序设计中起着非常重要的作用。控件是应用程序与用户的交互点。控件使用的好坏，直接关系到应用程序功能实现的质量以及操作界面是否友好。本文旨在探讨VFP中的Grid表格控件的一些使用方法。     

取消燃气和电力补贴对我国居民生活的影响

分析取消能源补贴对居民生活的影响是完善能源补贴改革的重要基础。本文首先应用价差法估算了中国2007年燃气和电力的补贴规模;其次考虑到中国居民贫富与区域差异,将城乡居民按收入水平分为10组,引入"能源预算"概念并设计"影响指数"、"承受力指数"等核心指标,结合投入产出模型,从直接和间接两方面综合研究了取消燃气和电力补贴对不同收入阶层居民生活的影响,分析结果表明无论从直接影响还是间接影响的角度,取消燃气和电力补贴对低收入阶层居民,尤其是农村低收入居民的冲击更大。最后基于实证分析结果,提出阶梯化定价机制与补贴转移等能够让低收入阶层居民真正获益的能源补贴改革建议。     

EE-IO modeling of the environmental impacts of Finnish imports using different data sources

The environmental impacts of Finnish imports were modeled using alternative emission datasets. The first dataset was based on domestic technology assumptions from the Finnish environmentally extended input-output (EE-IO) model. In the second dataset, emissions of the largest volumes of imported goods were substituted for EIOLCA (USA) data and in the third option for data from Ecoinvent and the Danish LCA Food Database. Comparative results show that the environmental impacts of imports based on domestic emission intensities are mostly lower than the alternative approaches. Considering the high level of Finnish environmental protection we concluded that the impacts of imports are underestimated using domestic emission intensities. Additionally, we concluded that hybrid IO modeling will increase the accuracy of IO modeling by using process-based data for the most relevant material flows until a multi-regional IO model for Finland has been developed.     

金刚藤丸联合热敷双柏散治疗湿热瘀阻型慢性盆腔炎患者的临床疗效

目的探讨金刚藤丸联合热敷双柏散治疗湿热瘀阻型慢性盆腔炎患者的临床疗效。方法选取2018年8月至2019年12月就诊于阳江市中医医院妇科门诊的湿热瘀阻型慢性盆腔炎患者120例作为研究对象,研究过程采用单盲法进行,将口服金刚藤丸联合热敷双柏散治疗的60例纳入观察组,口服金刚藤丸的60例纳入对照组。通过自制"疗效评分表"统计两组的综合疗效,比较两组治疗前后症状、体征评分变化。结果观察组治疗有效率为95.00,对照组治疗有效率91.67%,差异有统计学意义(P<0.05)。治疗后,两组患者症状、体征积分以及综合疗效积分均明显下降,差异有统计学意义(P<0.05)。结论金刚藤丸联合热敷双柏散对湿热瘀阻型慢性盆腔炎临床疗效显著。     

中国经济增长的动力来源与转换展望——基于最终需求角度的分析

基于最终需求视角分析中国经济增长的动力来源,可以为中国经济发展模式转变提供新的思路。本文利用国家统计局的投入产出数据,使用非竞争型投入产出模型,对1987—2007年间中国经济增长的动因进行了系统分析。结果表明:(1)包括消费、投资及出口在内的最终需求对于我国经济的拉动效果呈现下降趋势,当前经济的生产诱发效果重心主要在工业部门,且迅速地从轻工业向重工业转移;(2)1987—2007年间中国经济的依存结构发生了本质变化,经历了从"内需依存型"向"出口导向型"转变;(3)中国经济增长主要来源于最终需求的拉动,但动力来源结构在此期间发生了根本性的变化。最后,本文结合实证分析结果对中国经济发展方式转变提供了相关建议。
