包容性增长:公平与效率的交织进化

在我国经济发展的过程中,人们更多关注的是经济增长,追求"GDP主义",以实现经济的快速发展.但是在经济增长过程中产生了连带的社会问题,最大的问题莫过于收入分配不公.那么,在当前环境下,如何公平合理地分享中国经济发展成果当仁不让的成为我国经济发展所面临的一个重大问题."包容性增长"理论应运而生,契合了经济法治建设的时代要...     

社会核算矩阵与国民经济账户、投入产出表的关系研究

社会核算矩阵(SAM)刻画了社会经济主体间通过要素市场、商品市场而发生的交易和收支转移活动。结合国民经济核算理论研究了国民经济账户、投入产出(IO)表与SAM之间的关系,结果表明:SAM是以矩阵形式表示的国民经济核算体系(SNA)账户,SAM以复式记账的核算原则和矩阵的形式提供了国民经济的另外一种核算方式;IO表是编制SAM的重要数据来源。     

Variance-based sensitivity analysis with the uncertainties of the input variables and their distribution parameters

For the structural systems with both the uncertainties of input variables and their distribution parameters, three sensitivity indices are proposed to measure the influence of input variables, distribution parameters and their interactive effects. With those sensitivity indices, analysts can make a decision that whether it is worth to accumulate data of one distribution parameter to reduce its uncertainty. Due to the large computational cost, the analytical solutions are derived for quadratic polynomial output responses. Whereas for the complex models, state dependent parameter (SDP) method is utilized to solve the proposed sensitivity indices efficiently.     

Large courts,small justice!: The inefficiency and the optimal structure of the Italian justice sector

An important problem in the public sector, given the lack of output prices and exit decisions to sanction inefficient units, is finding the optimal industry structure. We apply a novel approach to Italian courts of justice, a typical example of a small sector in the public domain but with important effects on economic agents׳ behavior, firm size, FDI, and on the overall economy. The suggested approach enables us to break down the aggregate court inefficiency into different sources and to investigate the optimal structure of the justice sector. Results show that technical inefficiency (lack of best practice) accounts for more than one third (38%) of total inefficiency, while size inefficiency (courts that are too big) is about 22–25%. The remaining inefficiency is represented by a sub-optimal allocation of inputs (30–40%). If reallocation is confined to macroregional or regional borders, then technical and size inefficiencies increase in relative terms compared to reallocation inefficiency. We suggest that, together with reallocating inputs by merging smaller courts, a complementary set of policy interventions would be to adopt best practices and split larger courts.     

86系列微机接口实验装置的研制

本文介绍我们研制的一套结构简单、操作方便、成本低廉的86系列微机接口实验装置。该装置可直接调试运行86系列汇编程序，具有各类查询、中断输入／输出实验功能、键盘与显示器接口测试试验、打印机控制实验、D／S与A／D转换实验等。在传统的实验项目^[2]上增设了两组联接实验，并比现有的86系列机实验装置增多了输入功能。     

中国农业发展存在“结构红利”吗?

要素的有效配置对产业发展至关重要。在经典钱纳里模型的基础上加入人力资本,基于扩展的理论范式首次研究了我国2001-2012年要素再配置效应对农业发展的影响,结果发现:现阶段我国农业较快增长主要源自要素尤其是资本的驱动,传统的要素密集型的粗放式发展模式依然明显,要素再配置的“结构红利”极为微弱。资源在农业各部门间的错配导致了要素再配置效应的低下,而造成我国农业生产中资源错配的本质原因在于地区及部门间的垄断保护等扭曲性的制度安排。提高要素再配置效应,释放“结构红利”,关键在于不断突破阻碍要素自由合理流动的制度藩篱,充分发挥市场在资源配置中的决定性作用。     

贵州省经济增长动力分析

贵州省经济增长的动力值得高度重视。本文通过把要素投入和技术进步各因素纳入统一的框架进行研究,在对各变量进行单位根检验和协整检验的基础上确定贵州省经济增长与各因素的协整关系,进而计算出各因素对经济增长的作用大小并对其进行了解释。在此基础上,文章就保持贵州省经济持续高速增长、缩小与其它省份的差距提出了简要政策建议。     

课堂语言输入量对英语语言焦虑的影响

以增加课堂语言输入量可以降低语言焦虑为理论依据,在已经对英语082四个学期语言焦虑变化研究的基础上,调查了国贸082四个学期的语言焦虑变化情况,并且将两个班四个学期语言焦虑的变化做了横向比较,研究结果进一步表明,增加课堂语言输入量可以有效地降低学生的语言焦虑,但是课堂语言输入量必须达到阈值,按照本研究的结果,其阈值大概达到600～800课时数时,即可有效降低学生的语言焦虑。     

Diffusion, levelling, simplification and reallocation in past tense BE in the English Fens

In the dialect contact framework proposed by Trudgill (1986), relatively little research has investigated the consequences of the mixing of different grammatical systems of English. The apparent time survey of the Fenland dialect of eastern England reported here provides an example of a range of dialect contact processes reconfiguring variable patterns of past tense BE, resulting in a variety with analogical levelling to was in positive contexts –' the farms was '– and to weren't in negative clauses –' the farm weren't '. In focussing this was/weren't pattern, a number of the processes typical of koine´isation can be observed – diffusion (the geographical and/or social spread of a linguistic form from another socio-geographical place), levelling (the eradication of marked or minority forms in situations of dialect competition, where the number of variants in the output is dramatically reduced from the number in the input), simplification (a relative diminution of grammatical irregularity and redundancy) and reallocation (where two (or more) ingredient variants of the dialect mix are refunctionalised to serve new social, stylistic, or, as here, grammatical roles).     

高质量发展背景下的西藏全要素生产率研究

伴随着“提高全要素生产率”先后被正式写入国务院政府工作报告和党的十九大报告,近年来全要素生产率理论开始得到国内外学者的广泛关注。在此背景下,运用非参数DEA-Malmquist指数分析法对2000-2018年西藏全要素生产率进行了测算分解,并与同时期全国平均水平和主要民族地区水平进行了横向比较。研究结论表明,西藏当前正处于工业化前期向工业化中期的转型发展阶段,21世纪以来全要素生产率虽然呈现出“√”型的缓慢回升态势,但总体上仍然处于低位区间波动徘徊,相对滞后于全国和主要民族地区平均水平。因此,未来西藏经济要实现高质量发展的目标,迫切需要通过一系列有效改革措施,加快实现经济增长方式由要素投入拉动向全要素生产率驱动转变。
