农村政策性金融与财政支农关系

政策性金融的产生及其作用的发挥,实际上就是财政职能不断强化的一个产物,改革开放中后期以来,我国农村政策性金融体系的功能趋于弱化,其原因在于:财政实力被过多地削弱,公共产品资源配置不够合理,过分倚重商业性金融的支农效应而弱化了财政对农村政策性金融的支持。为此,应当健全财政对农村政策性金融持续投入机制与补偿机制,协调好财政政策与货币政策的关系,财政还应承担起对政策性金融业务监督管理的责任。     

Joint implementation under asymmetric information and strategic behavior

Joint Implementation (JI) under the Framework Convention on Climate Change means that countries could partly offset their national abatement commitments by investing in CO₂ abatement projects abroad. JI is introduced as a mechanism for achieving a certain global abatement target less costly by separating the commitments from the implementation of measures. This paper studies the design of a JI contract when the investor has incomplete information about the foreign firm which carries out the JI project (the host). Asymmetric information leads to a decrease in the potential cost savings from JI. Furthermore, private information held by the potential host firm could give the firm a significant positive utility of participating in JI projects. The possibility of being a host for a JI project in the future can prevent potential host firms from investing in profitable abatement projects today. The paper analyzes the impact on emissions of CO₂ of strategic behavior among potential hosts for JI projects.     

积极财政政策执行效果及隐忧问题研究——H省执行情况个案分析

基于凯恩斯主义国民收入决定理论 ,通过对H省经济运行数据的实证模拟 ,分析H省积极财政政策的执行情况 ,并结合H省省情和我国国情 ,我们得到了九个基本命题 :命题 1∶H省经济处于投资陷阱之中 ,因而货币政策无效 ,财政政策充分有效。命题 2∶H省的财政政策乘数为 5 596,投资需求拉动乘数为 2 3 945,消费需求拉动乘数为2 2 0 1 5,财政支出回馈乘数为 0 2 2 66。命题 3∶H省国债转贷与补助资金拉动的经济增长率为 :1 988年 0 6个百分点 ,1 999年 0 9个百分点 ,2 0 0 0年 0 6个百分点 ,2 0 0 1年 0 5个百分点。命题 4:乘数愈大 ,积极财政政策的效果愈大 ,但积极财政政策退出造成的负作用也愈大 ,总需求和经济增长对积极财政政策的依赖程度也愈强。命题 5,民营化程度愈低 ,投资的利率弹性愈低 ,货币政策愈无效 ,反之亦然。命题 6,民营化程度愈低 ,财政依赖程度愈强 ,反之亦然。命题 7:我国的积极财政政策必然会退出 ;退出的最佳方式是淡出 ;维持现有国债规模是淡出的最可能的形式 ,是一个聚点均衡。命题 8:H省的民营化程度低于全国的平均水平 ,财政依赖程度高于全国的平均水平 ,自主性增长动力尤显不足。命题 9:如果没有激励民间投资的有效措施出台 ,积极财政政策淡出将使H省经济增长速度下滑。     

关于我国财政政策导向调整的研究

近年来我国实施的积极财政政策确实在很大程度上促进了经济和社会的发展。但是随着经济市场化程度的不断提高和经济环境的变化，这种积极财政政策也表现出诸多的不适应性。因此应适时调整财政政策导向以适应经济和社会发展的新要求。拟从我国近年来实施的积极财政政策的成效分析出发，阐述了当前调整财政政策导向的必然性，并提出了今后我国财政政策的调整方向。     

Fiscal Policy in Europe: How Effective Are Automatic Stabilisers?

It is largely recognised that fiscal policy will have largerresponsibilities for cyclicalstabilisation in EMU given the loss of the monetary instrument.At the same time, theEMU's budgetary framework emphasises the need to rely onautomatic fiscal stabilisers,rather than active policies in cushioning the business cycle.We show that automaticstabilisers are relatively powerful in the event of shocksto private consumption, but lessso in the case of shocks to private investment and exports.In the case of supply sideshocks, the automatic stabilisers are largely ineffective,but this may actually be a goodthing to the extent that supply-side disturbances call forstructural adjustment rather thancyclical stabilisation.     

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。     

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.     

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。

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.
