A grey decision and prediction model for investment in the core competitiveness of product development

Because enterprises do not disclose their internal specific cost information to the public and, moreover, every firm has its own product character and financial constitutions, it is difficult to offer fixed guidelines for investment decisions. Thus, an enterprise may be uncertain when required to choose the most promising set of possible investments.The goal of this research is to use a grey relation analysis and analytic hierarchy process (AHP) to probe the core product development and competitiveness of an enterprise from limited data and, furthermore, by constructing the grey model, GM(1,1), to validate the feasibility of this assessment of the core competitiveness and investment strategy. In this study, a precision mechanical manufacturer is taken as an example, and the forecast estimate from this method is compared to those of a linear regression and the actual values to demonstrate the feasibility of applying this methodology to investment decision making, hence, demonstrating the value of this research.     

基本养老保险筹资权行使主体的确定及其理论依据

基本养老保险筹资权的行使主体的确定问题,应从中央与地方政府财权划分的角度进行分析。我国地方政府行使基本养老保险筹资权存在不合理性,应建立由中央政府统筹的基本养老保险制度。     

三层次制度环境视角下创新驱动发展评价研究——以中西部6省市为例

借鉴改进的DSIR模型思想,从政府-企业-个人3个层次出发,将制度环境作为一个外生子系统,引入创新驱动战略评价系统,形成制度环境-驱动力-状态-影响-响应5个立体层面的子系统,同时,采用混合型中心点三角白化权函数进行灰色评估分析,对中西部地区6个省市创新驱动发展状况进行实证研究。分析结果表明,在创新驱动发展方面,四川处于同类地区“领跑”地位,河南、湖北、湖南处于“并跑”地位,而陕西和重庆处于落后地位,针对各地区发展短板提出对策建议。     

财政分权与地方政府行为异化

作为财政体制改革的后果,财政分权导致政府间财政竞争,并改变了财政均等状况。中国国情的特殊性,尤其是官员委任制以及以经济增长为核心的地方政府官员政绩考核体系,使得政府间财政竞争更易导致地方政府财政支出结构呈现结构性扭曲。因此,制订合理的政绩考核标准,并相应调整财政体制是规范地方政府行为的当务之急。     

A study of zoning for energy security in China

As a result of more and more serious energy risks, the study of national energy security zoning is not only the basic requirement of energy risk management but also the new demand of economic development for the energy industry. Firstly, this paper analyzes the basic situation of energy resources and production and consumption of primary. energy from 1996 to 2005 in China. Secondly; this paper founds an Energy Security Index System formed by six indices including the percentage of energy reserves, interlocal dependent degree, energy elasticity coefficient and so on. It subsequently calculates the weight of these indices with the factor analysis rating method Lastly, the paper evaluates and zones the abilities of energy security of 30 provinces in China with the grey chuster method According to their security; the 30 provinces are classified into three different levels： high, medium, and low levels. The regions at low energy security level include Beijing, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi and Hainan. They are mainly littoral and short of primary energy production while mostly dependent on other provinces. Those at medium energy security level include 15 provinces （cities or districts）, such as Liaoning, Tianjin, Hebei, Shandong, Henan, Hunan and so on. These provinces are in the northeast, north, east of and central China. Those at high energy security level contain Shanxi. lnner Mongolia, Heilongjiang, Jilin, Chongqing, Sichuan, Shaanxi. Xinjiang. These provinces are the main primary energy production bases.     

国家级新区绿色增长能力建设影响因素分析

基于利益相关者理论,通过文献研究与实地调研,梳理了影响国家级新区绿色增长能力建设的主要因素,并应用Grey DEMATEL方法进行影响因素因果关系分析,在此基础上进一步剖析国家级新区绿色增长能力建设内在机理。研究结果表明：法律法规完善性是影响国家级新区绿色增长能力建设的根本性动力因素,同时,也是新区绿色增长能力建设内在机理的重要外在驱动力。此外,当地居民环境意识也是影响国家级新区绿色增长能力建设的重要结果性因素,而企业绿色管理实践、绿色技术进步与创新能力作为重要的关键性因素,对国家级新区绿色增长能力作用显著,是国家级新区绿色增长能力建设的重要内在驱动力。     

供应链节点企业的贡献度和关联度评估

定量地分析节点企业对供应链的贡献大小及其与其他节点企业联系的紧密程度是供应链研究的一个难点。文中采用多属性的模糊关系矩阵建模方法,以光伏行业为例,评估各个节点企业的贡献度和关联度。     

基于灰色关联分析的企业IT应用水平提升路径研究

在实证调研的基础上,应用灰色关联理论,对企业的管理制度能力和流程管理能力与IT应用水平进行灰色关联分析,发现企业IT应用水平不同阶段,这两种能力与IT应用水平的关联度存在差异,表明企业IT应用发展规律在不同IT应用阶段相对应的制度能力和流程管理能力不同。由此,提出企业在选择提升IT应用水平路径上应当关注在不同时期与IT应用水平相对应的制度能力和流程管理能力的培育和强化。
