Outside the box: using synthetic control methods as a forecasting technique

We introduce synthetic control methods (SCM) as a forecasting technique. Using (i) as economic predictors solely the outcome itself, i.e. lagged values of the dependent variable, and (ii) lagged time series of the outcome to build the donor pool, we let SCM choose and weight appropriate values in order to come up with a sensible forecast of the US GDP growth. This procedure performs competitively viable compared with alternative forecasting methods.     

垂直型生鲜电商经营有效率吗？——基于考虑环境因素的三阶段DEA模型的实证

作为一种新型流通主体,生鲜电商被寄予厚望,其效率提高有助于破解我国生鲜农产品流通困境。文章运用三阶段DEA方法,在控制环境因素及随机误差的基础上,测度了垂直型生鲜电商的经营效率。研究发现：垂直型生鲜电商效率整体较低,不仅普遍规模效率较低,管理水平也相对低下;环境因素对垂直型生鲜电商效率存在明显影响,其中,物流基础设施水平和人口素质对效率产生显著的正向影响,而信息化水平和以人均收入表征的地区经济发展水平对效率有显著负向影响。研究结论为垂直型生鲜电商提升效率提供启示。     

Impact of input substitution and output transformation on data envelopment analysis decisions

Data envelopment analysis (DEA) can aid managerial decision-making because it offers an opportunity to measure organizational performance in a holistic manner, aggregating data from partial indicators into a single comprehensive measure. However, there are some methodological hazards associated with the use of DEA that are especially relevant to managerial decisions, but which have been largely ignored in the literature. Herein, we identify and show the impact of a ubiquitous methodological hazard in DEA modelling – the economic assumptions regarding input substitutions and output transformations.     

Efficiency change,technological change and capital accumulation in Italian regions: a sectoral study

This paper examines the sources of labour productivity in the Italian regions during the period 1980–2004. Five economic sectors are investigated using data envelopment analysis (DEA) and taking into account productive specialisation and sector inefficiencies. Labour productivity change is decomposed into five components by means of Malmquist productivity indices: intra-sector efficiency change, composition efficiency change, input-biased technical change, magnitude component technical change and capital accumulation. Using bootstrap procedure, the components of labour productivity changes are statistically tested. Efficiency analysis shows that productive specialisation is not a source of inefficiency and efficiency gains can be obtained by sector-specific policies. Thus, it is possible to obtain improvements in efficiency in each sector of activity rather than reallocating resources among sectors. The results of the decomposition by sectors reveal heterogeneous sources of growth. The total economy has shown evidence of non-neutral technical change and, it has been found that agriculture, industry and construction experienced capital using technical change. The analysis of the decomposition of the labour productivity growth is complemented by an analysis of β-convergence.     

高校科研业绩量化评价中的常见陷阱及超越策略

如何全面、客观、科学合理地评价各高校及高校内部各机构、各学科和各科研人员的科研业绩,是每个高校都必须尽力解决好的一个非常重要而又较为困难的问题。目前,大部分高校科研评价中都或多或少地存在偏差,其部分根源在于3种陷阱,即对学科间存在的学科差异了解不够,对各种科研成果的宏观总量了解不够,对各类科研活动及成果的真实发展速度了解不够。对此,提出了基于同类相比原则的数量与占比相结合的高校科研评价方法,强调科研管理部门尽量全面掌握各学科性质差异、各类数据库的收录范围和年度收录总量变化情况,以及各类科研成果产出总量的发展态势。该方法的实施有利于更科学、公正、合理地做好高校科研业绩评价工作。     

基于DEA的风电项目并网消纳能力研究

针对我国风电装机容量迅猛发展,但送出等能力不足的形势,研究风电项目并网消纳能力。首先构建了包含基础特性等4个方面在内的一级评价指标,后完善至包含风电出力稳定性等15个二级指标在内的风电项目并网消纳能力综合评价指标体系,最后运用数据包络法对五个风电项目进行算例分析。结果表明DEA方法适用于风电项目并网消纳能力的研究。     

基于DEA的江苏工业细分行业技术创新效率评价

以江苏工业2003-2014年35个细分行业的数据为依据,运用DEA模型,对其技术创新效率进行测度与评价,并将其分解为规模效率和纯技术效率。认为2003年以来,江苏工业技术创新效率不断提高,尤其是2011年后出现较大幅度的增长,规模效率的变动幅度与综合技术效率的变动幅度基本一致,纯技术效率的变动相对平稳。但江苏工业技术创新的整体效率较低,仅为0.585,这是纯技术效率（0.723）和规模效率（0.803）不高综合作用的结果。江苏工业技术创新效率具有明显的行业特性,行业间差异显著。     

基于DEA的产业效率分析——通信设备、计算机及其他电子设备制造业的实证分析

本文对通信设备、计算机及其他电子设备制造业的产业效率及其技术变动情况进行评估.选取58家营业收入排名靠前的企业集团作为样本企业,结合DEA方法,从微观、静态和动态等角度对产业结构效率、产业整体技术变动情况进行了讨论.研究结果表明,从2004～2006年,我国通信设备、计算机及其他电子设备制造业的结构效率经历了先上升再下降的过程,虽然总体趋势上升,但整体技术水平却在不断下降.其中的主要原因包括产业结构不合理等.
