运用互联网与大数据推进产业发展的路径分析

目前以移动互联网、大数据、云计算、物联网等为代表的新一代信息通信技术创新活跃,加速向各行业领域渗透并形成新的经济增长点。湖北省正在加紧推进智慧湖北建设,而紧抓互联网与大数据为主要内容的信息技术发展,是抢占新一轮智慧发展战略制高点的关键所在。在立足国内外互联网与大数据推进产业发展态势、总结相关学者研究成果的基础上,以湖北省互联网与大数据推进产业发展为例,指出当前还存在数据共享不足、数据安全风险、缺乏标杆企业、产业链协同不足、关键技术储备不够、信息基础设施滞后等问题,针对上述问题及问题成因,从政策创新、产业发展着力点下、市场环境建设等方面提出有针对性的对策建议。     

Forecasting MBT technologies using DEA and LR

First, this paper explores Main Battle Tank (MBT) data set with different statistical methods in order to decide the most appropriate variables as reliable yardsticks in applying technology forecasting (TF) using data envelopment analysis (TFDEA) technique. It then applies TF using DEA method to forecast MBT technologies. This article attempts to predict technology development year of MBT commercialised from 1941 to 1994. This article presents the processes of TFDEA in detail and identifies some issues to search for appropriate input and output variables to forecast MBT technologies. The purpose of this study is to address some issues and identify an appropriate data to predict future trends of MBT technologies when using TFDEA and multiple linear regression tools. Finally, the study provides an understanding of the technological advances being sought in MBT technologies and information for use in making decisions regarding development strategy.     

生态文明建设视角下国家可持续发展实验区资源配置评价

建设国家可持续发展实验区是实施可持续发展和生态文明建设的重要战略,对实验区资源配置效率进行科学评价可以为其提供重要决策依据。以生态文明建设为主线,兼顾社会经济发展目标,从优化国土空间格局、自然生态环保、资源节约提升及生态文明制度建设4个方面,统筹建立国家可持续发展实验区资源配置效率评价指标体系,运用数据包络分析方法构建国家可持续发展实验区资源配置效率评价模型,对实验区资源配置效率进行纵向和横向两个维度的评价。以湖北省国家可持续发展实验区资源配置为例进行实证分析,验证了模型有效性,可为衡量和提升国家可持续发展实验区建设水平提供决策参考。

What Makes Business Statistics Special?

Non-specialists might have the feeling that building statistics on businesses is a very simple task: it seems one just has to "add facts". But for survey statisticians, business statistics are extremely complex: great heterogeneity of the universe, definition of the statistical units, difficulty of classifying businesses, quality of the register, variety of accounting standards, sample co-ordination, or reduction of survey burden. This paper argues that the issues raised by business survey methodology are conceptual and not only practical. It describes different aspects of statistical processing and tries to analyse the special features of business statistics.     

Projections Onto Efficient Frontiers: Theoretical and Computational Extensions to DEA

Data Envelopment Analysis (DEA) has been widely studied in the literature since its inception in 1978. The methodology behind the classical DEA, the oriented method, is to hold inputs (outputs) constant and to determine how much of an improvement in the output (input) dimensions is necessary in order to become efficient. This paper extends this methodology in two substantive ways. First, a method is developed that determines the least-norm projection from an inefficient DMU to the efficient frontier in both the input and output space simultaneously, and second, introduces the notion of the observable frontier and its subsequent projection. The observable frontier is the portion of the frontier that has been experienced by other DMUs (or convex combinations of such) and thus, the projection onto this portion of the frontier guarantees a recommendation that has already been demonstrated by an existing DMU or a convex combination of existing DMUs. A numerical example is used to illustrate the importance of these two methodological extensions.     

完善我国累积投票权制度立法的构想

我国大股东对中小股东侵害行为非常普遍,究其根源,上市公司中的一股独大、<公司法>对表决权的规定简单、现有表决权存在缺陷、中小股东法律意识淡漠是主要原因.目前当务之急是要在<公司法>上明确赋予小股东一定的权利,参考发达国家的经验做法,在法律上推行强制性累积投票权制度.     

中国信贷资本配置效率的空间差异:基于四大区域及省际面板数据的实证分析

帕累托式的信贷区域配置对协调区域经济增长有重要意义.对信贷资本的区域配置效率进行的实证研究表明:尽管宏观经济严重依赖银行信贷,但信贷配置效率差强人意;信贷配置效率的区域差异主要体现为省际层面而非区域层面.与区域经济一体化趋势形成鲜明对比的是,四大区域之间的信贷配置效率并无实质性差异.省际层面上,信贷配置效率差异非常显著,西部大多数省份和东部的浙江、江苏对信贷依赖程度较大;东部的上海、广东因多元化的金融体系而降低了对信贷的依赖;中部和东北的信贷配置效率较低且基本处于同一水平.
