我国经济增长中制度因素的实证分析

经济增长的决定因素是技术还是制度?学术界的争论由来已久,至今尚无定论。本文运用中国改革开放后的一些统计资料,通过计量研究,从经济增长中的诸因素中分离出来了制度因素,并测算了制度因素对经济增长的贡献。得出的结论是:在我国经济转轨时期,制度因素对经济增长的作用大于纯技术进步对经济增长的促进作用。因而,制度因素应是目前和今后一个时期我国经济增长的关键因素,抛开制度条件而片面地强调科技的第一生产力作用很可能不会取得预期效果。     

对环境税的经济学分析

随着我国经济的加速发展,环境问题越来越成为人们普遍关心的问题,成为影响经济进一步发展的制约因素。通过对环境税的经济学分析可以看出其较强的可行性和操作性。利用环境税矫正外部经济,从而达到运用税收手段保护环境的目的,是十分必要的。     

H-O国际贸易理论的新兴古典分析--交易效率对国际贸易的影响

赫克歇尔一俄林的生产要素禀赋理论作为主流经济学派理论在国际贸易理论总体系中的影响力是巨大和深远的。而新兴古典贸易理论的发展，为解释国内贸易和国际贸易提供了一个统一的理论内核。这一理论的完美框架和强大的现实解释力引人瞩目。其理论的核心在于该理论独特的分析工具：超边际分析方法。采用新兴古典经济学的超边际分析法，引入交易效率，对赫克歇尔-俄林的生产要素禀赋理论进行新的分析，可以得出很多有价值的结论。     

对美国新经济的认识

所谓新经济 ,其实是对美国经济领域出现的新现象、新变化、新趋势的反映和描述。新经济虽然对美国2 0世纪经济繁荣功不可没 ,但无论在哪个方面都还作用有限。我们要结合国情认真研究新经济动向 ,促进对新经济的消化、吸收 ,最重要的是应按照既定的步骤完成我们的战略目标。     

西方经济理论对中国经济改革与发展的影响--与刘国光教授商榷

刘国光教授认为西方经济理论没有对中国经济改革起到过指导作用,这种观点是不符合历史事实的.西方经济理论确确实实对我国经济改革产生过深刻的影响,西方经济理论的传播和西方经济学者的来访丰富了我国经济学者对于市场经济的认识,对指导我国经济改革与发展发挥了一定作用.     

贵州经济增长的影响因素研究:计量模型及实证分析

贵州目前的主要经济指标与全国平均水平相比仍有很大差距.借鉴C-D生产函数,选取物质资本、人力资本以及劳动力作为经济增长的主要影响因素,建立经济增长的模型并对这些因素进行实证分析,得出的结论是:贵州要保持经济的持续增长,需要从树立科学的发展观、加快产业结构调整、重视人力资本投资以提高劳动者素质、降低农村人口比重、加快城镇化进程以及进行制度创新等方面进行努力.     

数字经济推动区域经济增长的实证研究——基于长江经济带2010-2019年数据

数字经济目前已经成为国民经济发展的重要推动力,研究数字经济对区域经济增长所起到的推动作用具有非常重要的现实指导意义。搭建数字经济发展测评体系和区域经济发展水平测量体系,通过对长江经济带2010-2019年相关指标数据的搜集,测算了长江经济带数字经济发展水平与整体经济发展水平,并对二者之间的耦合关系进行了验证,研究发现,长江经济带的整体数字经济发展水平相对均衡,数字经济对于区域经济增长有显著的推动作用,同时针对长江经济带数字经济助力经济增长给出了管理层面的建议。     

Economic Growth and Transboundary Pollution in Europe: An Empirical Analysis

The existing empirical evidence suggests that environmental Kuznets curvesonly exist for pollutants with semi-local and medium term impacts.Ansuategi and Perrings (2000) have considered the behavioral basis for thecorrelation observed between different spatial incidence of environmentaldegradation and the relation between economic growth and environmentalquality. They show that self-interested planners following a Nash-typestrategy tend to address environmental effects sequentially: addressingthose with the most immediate costs first, and those whose costs aredisplaced in space later. This paper tests such behavioral basis in thecontext of sulphur dioxide emissions in Europe.     

The nature of the steady state in models of optimal growth under uncertainty

Summary. We study a one-sector stochastic optimal growth model with a representative agent. Utility is logarithmic and the production function is of the Cobb-Douglas form with capital exponent . Production is affected by a multiplicative shock taking one of two values with positive probabilities p and 1-p. It is well known that for this economy, optimal paths converge to a unique steady state, which is an invariant distribution. We are concerned with properties of this distribution. By using the theory of Iterated Function Systems, we are able to characterize such a distribution in terms of singularity versus absolute continuity as parameters and p change. We establish mutual singularity of the invariant distributions as p varies between 0 and 1 whenever . More delicate is the case . Singularity with respect to Lebesgue measure also appears for values such that . For and Peres and Solomyak (1998) have shown that the distribution is a.e. absolutely continuous. Characterization of the invariant distribution in the remaining cases is still an open question. The entire analysis is summarized through a bifurcation diagram, drawn in terms of pairs .Received: 9 April 2002, Revised: 29 October 2002, JEL Classification Numbers: C61, O41.Correspondence to: Tapan MitraThis research was partially supported by CNR (Italy) under the "Short-term mobility" program and by M.U.R.S.T.

Teams, Firms and the Evolution of Profit Seeking Behavior

Even as advances in information theory over the last quarter century have cast increasing doubt on the proposition that firms successfully maximize profits, the objective of profit maximization continues to be an axiomatic feature of the neoclassical theory of the firm. This paper attempts to improve our understanding firms by treating the objective function as an open question. Specifically, an ontogenetic thought experiment is undertaken to address the question of what differentiates production teams from firms by asking why team members would sell their control rights to a principal, thereby transforming the team into a firm. What results is an account of the emergence of the objective of profit seeking. Profit seeking emerges endogenously as a more fit alternative than the objective of value maximization, which is less capable of coping with uncertainty through purposive adaptation.
