进城农民工社会保障的影响因素研究

缺乏明确的法律规定、不同制度模式之间难以互通互联及其自身的缺陷,是制约进城农民工参加社会保障的重要制度性因素;性别、城市工作年限、是否签订劳动合同、工资收入、所在城市等则是影响进城农民工参加社会保障的非制度性因素。从制度创新和强化执法等方面提出了政策建议。     

基于哈肯模型的高技术产业化过程机制研究

运用自组织理论和方法,在哈肯模型的基础上建立了高技术产业化过程的演化方程,并以北京、天津、上海、河北等29个省市为样本进行了定量化的实证研究。结果表明,研究开发投入强度是高技术产业化过程中的序参量,从而得出要依靠研究开发投入与高科技成果转化的协同作用促进高技术产业快速发展这一结论。     

Growth,Employment and Taxation with Distortions in the Goods and Labour Market

Abstract. This paper analyses taxation in the presence of distortions in goods and labour markets in an endogenous growth model. The government disposes of capital, labour and consumption taxes. It is shown that the market solution leads to suboptimally low levels of growth and employment. However, available tax instruments are sufficient to attain the first‐best growth path in this economy. The paper further explores the relative distortion of capital and labour taxes. For plausible parametrisations of the model, lowering capital taxes dominate reductions in labour taxes in welfare terms.     

客户关系管理中的价值研究框架分析

价值研究是客户关系管理研究中基础而关键的问题。现有的价值研究多半是基于企业信息完全的假设上的,但是这个假设在实践中往往很难成立。因此很有必要讨论在信息不完全和不对称的环境下价值信息的获取。可以利用信息经济学中的契约设计的原理在信息不对称的环境下获取客户价值信息。     

绿色建筑经济激励政策分析

绿色建筑难以推广的原因是绿色建筑的经济外部性问题,而解决外部性问题的通常做法是政府干预。我们从经济学的角度,对经济激励政策的原理进行了分析,除此之外,还重点对绿色建筑的外部经济性和非绿色建筑的外部不经济性进行剖析,最后我们提出了一些促进绿色建筑产业发展的建议。     

基于生态足迹模型的可持续性度量研究--以吉林省大安市为例

针对吉林省大安市发展现状和存在的严重生态环境问题,运用生态足迹模型,采用多源数据,首次对大安市生态环境的可持续发展状况进行了定量研究;在此基础上,运用相对指标法对可持续发展的量化结果进行分级。研究表明,2001年大安市的生态需求大于生态供给,生态呈现“供不应求”的局面,人均生态赤字为0.56hm2,处于弱不可持续发展状态。

政府机构节能是全社会降低能源消耗、提高能源效率的关键环节。文章系统地分析了政府机构节能的内涵、机理,探讨了政府机构节能政策的适应性,有针对性地提出了我国政府机构节能的管理运行框架体系和政策措施建议。     

会计管制与公司治理

本文从企业契约理论出发,在回顾会计管制国际经验的基础上,将会计管制引入对公司治理问题的思考,指出了会计管制目标的实现对解决公司治理问题的重要性。其不仅要求反思会计管制理论与实践,同时要求在具体分析公司治理模式的基础上,重新思考会计管制的目标及其实现问题。提出应从现行公司治理框架下改进会计管制措施,从而实现会计管制与公司治理的良性互动。     

Building the Knowledge Stock: Lags,Depreciation, and Uncertainty in R&D Investment and Link with Productivity Growth

The search for an appropriate methodology to investigate the relation between R&D investment, knowledge stock and productivity growth is the main purpose of the paper. In analogy with physical assets, we present a model of knowledge capital formation which allows the calculation of the relevant user cost, as well. The proposed model accumulates R&D investment based on a stochastic gestation lag and a geometric depreciation of the stock. The basic parameters underlying the lag structure differ according to the types of research expenditure. The approach is applied to public R&D investment in Italian agriculture; the results provide interesting information about the economic structure of public research effort in Italian agriculture and plausible estimates of its internal rate of return.     

A substitution orbit model of competitive innovations

Successful innovation and diffusion of technology can be attributed to the identification of the orbit of emerging new technologies that complement or substitute for existing technologies. This dynamism resembles the co-evolution process in an ecosystem. In an ecosystem, in order to maintain sustainable development, the complex interplay between competition and cooperation, typically observed in predator-prey systems, create a sophisticated balance. Given that an ecosystem can be used as a masterpiece system, this sophisticated balance can provide suggestive ideas for identifying an optimal orbit of competitive innovations with complement or substitution dynamism.Prompted by such a sophisticated balance in an ecosystem, this paper analyzes the optimal orbit of competitive innovations and, on the basis of an application of Lotka-Volterra equations, it reviews substitution orbits of Japan's monochrome to color TV system, fixed telephones to cellular telephones, cellular telephones to mobile Internet access service, and analog to digital TV broadcasting. On the basis of substitution orbits analyses, it attempts to extract suggestions supportive to identifying an optimal policy option in a complex orbit leading to expected orbit.Key findings include policy options that are effective in controlling parameters for Lotka-Volterra equations leading to expected orbit.
