 [PDF]

Service Science and Management (SSEM) , 2014, DOI: 10.12677/SSEM.2014.34B008
Abstract:

基于创业胜任力理论视角,提出了创业倾向的胜任力作用模型及其理论假设;然后通过上海松江大学城问卷调查的大样本数据进行实证分析。分析结果显示,创业原动力、机会把握力、创新创造力和关系胜任力四个胜任力对创业倾向具有显著影响,且具有非常强的总体方差解释力(62%)。模型还显示,创业原动力和机会把握力对创业倾向具有直接的影响作用;创新创造力和关系胜任力的影响作用是间接的,主要通过创业原动力和机会把握力的中介作用对创业倾向产生影响。

Based on the theory of the entrepreneurial competency and the entrepreneurial intention, we deduced the hypotheses on how entrepreneurial competencies affect the entrepreneurial intention. These hypotheses were tested with 362 samples data through SEM analysis. The analysis result shows that entrepreneurial competencies have a significant impact on the entrepreneurial intention, which explains 62 percent of variance of intention. The model shows that the entrepreneurial intention is significantly affected by four dimensions of the entrepreneurial competency which are separately called the entrepreneurial motivation, the opportunity competency, the innovation competency and the relationship competency. The entrepreneurial motivation and the opportunity competency have a direct effect on the entrepreneurial intention while the innovation competency and the relationship competency indirectly affect it. Actually, the former two competencies are mediators for the latter two. Furthermore, the relationship competency has a significant impact on the innovation competency.

Abstract:
利用有限元对索拉穹顶进行了特征值屈曲分析,得到了索拉穹顶的屈曲模态,并确定出最不利的屈曲模态阶数。通过讨论几何缺陷形式、大小的变化对结构弹塑性承载力的影响,进一步分析了预应力和杆件截面变化时几何缺陷对弹塑性承载力的影响。分析结果表明:第二阶特征值屈曲模态的缺陷形式对结构最不利;随着拉索预应力的增加,几何缺陷对弹塑性承载力的影响先不变后减小;钢杆件截面改变时,几何缺陷对弹塑性承载力的影响基本不变。
Eigenvalue buckling analysis of solar dome was done firstly, then the the buckling modes were got and the most unfavorable mode was pointed. The influence factors of bearing capacity, such as the form and bigness of geometric defect, were discussed. The influence of prestress and the section of rod was further studied. The result shows: The second-order buckling mode is the most unfavorable mode; as the prestress of rop grows, the influence of geometric defect to elastoplastic carrying capacity increases firstly and then decreases; as the section of rod changes, the influence of geometric defect to elastoplastic carrying capacity essentially unchanged.

Abstract:
畜牧业集约化发展,随之带来的污染问题越来越严重,对农业生态和食品安全造成威胁,也成为妨碍禽畜养殖产业健康发展的重要因素。本文运用成本效益模型分析德清源沼气发电工程的经济可行性,得出集约养殖企业可以通过沼气发电能源工程串起粪污综合利用的循环农业产业链,实现畜牧业污染物从“治”到“化”的转变。同时,在分析中得出养殖业沼气发电存在的经济效益未凸显、电量收购、补贴及产业链断裂等问题,针对问题对集约养殖沼气发电提出几点建议。
With the development of stockbreeding, a lot of problems have been brought. The pollution is more and more serious, which has become a threat to the agricultural ecology and food safety. The pollution seriously affected the healthy development of the breeding industry simultaneously. In this paper, through the empirical analysis of Deqingyuan biogas power electricity generation en-gineering, it resulted that the breeding industry could make up a circulation agriculture industry chain by the project of biogas power electricity generation and change the situation of the livestock pollution from “cure” to “utilization”. At the same time, through the analysis, there are several problems, such as the economic benefits not reflected, the acquisition of power, subsidies and industrial-strand breaks. At last, there will be some suggestions to the biogas power electricity generation in breeding industry.

Abstract:
“十二五”期间,我国在部分城市开始节能减排财政政策综合示范,通过整合财政政策,加大资金投入力度,我国节能减排进入新的发展阶段。以财政政策示范工作的主要内容为出发点,利用实证分析的方法,从产业低碳化、交通清洁化、建筑绿色化、服务业集约化、主要污染物减量化、可再生能源利用规模化六个方面对长沙市财政支持重点领域节能减排进行绩效评价。长沙市作为首批综合示范城市之一,节能减排工作在示范期间取得重大突破,但仍存在财政资金不足、财政政策与其他政策联动性弱、企业与公众参与度低等问题,最后提出对策建议。
During the “Twelve Five” period, China began to integrate the fiscal policy of energy conservation and emission reduction and increase financial investment. China’s energy-saving emission reduction had gained a new stage. Taking the work of fiscal policy as the starting point, we use the method of empirical analysis and evaluate the performance of key areas of energy-saving emission reduction about Changsha financial support from six aspects about the low carbon industry, trans- portation, construction, green cleaning service industry intensive, major pollutants reduction and renewable energy scale. As one of the first comprehensive demonstration cities, Changsha’s work has made a major breakthrough in the demonstration period. However, there are still problems. Fiscal policy can’t be well linked with other policy; the activity about enterprise and public participation is low. Finally, we put forward some measures and suggestions.

寿险定价的线性优化模型

中国管理科学 , 2014,
Abstract: ?实际的金融市场中存在多种不同期限的利率。在定义最大累积函数的基础上建立了一个称为“收支问题”的线性规划模型,这个模型的最优值刻画了合理安排保费资金的投资期限所能够达到的最大保险支付水平,从而给出了多利率条件下寿险费率的计算依据。使用局部优化方法证明了收支问题最优解的两个性质,这些性质说明在满足保险支出的条件下,保险收入资金应该优先考虑期限较长(即利率较大)的投资。对于典型的寿险产品模型,给出了最优解的结构,针对两个具体实例列出了计算结果。结果表明,在保险费率的计算中,起主要作用的是最大期限的利率,其次是不同利率的一个综合水平。
基于EVA的经理人薪酬激励模式

财会月刊 , 2009,
Abstract: 本文对基于经济增加值的经理人薪酬激励模式进行了创新研究,具体设计了经理人年度薪酬收入模型、薪酬银行和年度薪酬支付模型。该模式的激励机制是:使经理人和股东的利益追求趋于一致,对经理人的奖励具有足够强的可变性,对经理人进行真实激励,使代理成本保持在一个合理的水平上。  【关键词】经济增加值经理人薪酬激励模式经济增加值(EVA)是最具影响力,也是最贴近企业管理实践的一种价值管理型业绩评价方法。基于EVA的经理人薪酬激励模式以激励长期价值创造为核心,实现股东和经营者的“双赢”。在“企业价值最大化”逐渐成为评价企业全球化的标准的今天,引入EVA指标,以价值创造为导向,对我国企业的经理人薪酬激励模式进行创新成为亟待解决的问题。  一、基于EVA的经理人薪酬激励模式的设计  1.设计思想。本文的设计思想为:①以实现企业价值最大化为激励目标;②与笔者所设计的业绩评价模型相统一,对财务表现和非财务表现进行综合激励;③有奖有罚,薪酬上不封顶,不设限额;④延长激励年限,使其具备长期激励功能;⑤体现相对业绩激励思想,以剔除行业系统因素对业绩评价的影响;⑥简单实用,易于操作;⑦降低代理成本;⑧采用增量激励。
