基于利益相关者视角的浙江专业市场物流配送机制研究

浙江专业市场物流配送活动存在着错综复杂的利益相关者,他们的行为决定了浙江专业市场物流配送机制的构建模式,对物流配送活动产生重大影响。浙江专业市场物流配送机制的构建应该围绕产业集群需求打造物流支持系统,创新物流服务模式和运营组织形式,通过打造第三方供应链物流服务平台、大力发展第四方物流和电子商务物流,以及培养高素质复合型物流技术人才,促进物流配送服务升级和专业市场转型提升。     

关于现代产业经济学前沿问题研究

随着国民经济的发展,现代化经济产业布局基本完成,同时在经济发展过程中涌现出一些现代产业经济学相关问题,探究这些经济学前沿问题对助推现代化经济突破发展瓶颈、实现可持续健康发展有重要意义。基于这一背景,论文首先剖析现代产业经济学前沿问题研究的意义,之后列举当前国内主要存在的一些前沿问题,并提出对应解决策略,以期能够为助推国民经济稳步发展提供一定的理论和实践参考。     

Mortality,Human Capital and Persistent Inequality

Available evidence suggests high intergenerational correlation of economic status and persistent disparities in health status between the rich and the poor. This paper proposes a mechanism linking the two. We introduce health capital into a two-period overlapping generations model. Private health investment improves the probability of surviving from the first period of life to the next and, along with education, enhances an individual’s labor productivity. Poorer parents are of poor health, unable to invest much in reducing mortality risk and improving their human capital. Consequently, they leave less for their progeny. Despite convex preferences and technologies, initial differences in economic and health status may perpetuate across generations when annuities markets are imperfect.Additional support was provided by the National Science Foundation.

民营企业建立现代企业制度相关问题分析

我国民营公司制企业,特别是非上市有限责任公司,仍然是封闭式家族企业。既使是上市公司,其目的也是通过上市筹集资金,现代公司治理结构的改造进展缓慢。我国民营企业进行现代企业制度改造,其重点不是消除家族企业色彩,改制主要围绕完善内部管理,提高经营管理水平和企业决策的科学性。通过建立健全企业内部规章制度,规范企业行为,使民营企业能够按政府颁布的法律法规开展生产经营活动。     

构造与市场经济相适应的现代公有制形式

公有制的改革与发展问题是建设有中国特色社会主义经济的核心问题。要完善社会主义初级阶段基本经济制度，实现公有制与市场经济的结合，只在公有制的实现形式上做文章是不够的，还必须高度重视和认其解决公有制本身的存在形式即公有制形式问题。     

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.

城乡居民收入差距的动态演变:1988～2002年

中国城乡居民收入差距已经引起广泛关注。文章以住户调查数据为基础,利用泰尔指数分解、G.Fields分解、Blinder分解、分位回归分解等多种方法讨论了1988年、1995年和2002年“城乡”因素本身对城乡居民收入差距的贡献。这些分解结果表明我国的城乡差距较显著并在不断扩大;而且城乡差距更不利于农村中的低收入人群。     

Structural Decomposition Analysis of Physical Flows in the Economy

Many environmental problems can be attributedto the extraction and emissions of physicalsubstances. Increasing our understanding of theeconomic and technological driving forcesbehind these physical flows can contribute tosolving the environmental problems related tothem. The input-output framework is a usefulsetting in which to integrate detailedinformation about economic structure andphysical flows. In this article a specificmethod in input-output analysis is reviewed,namely Structural Decomposition Analysis (SDA).It is based on comparative static analysis,which decomposes historical changes of a policyvariable into determinant effects. SDA has beenapplied, for example, to analyze the demand andtechnological driving forces of energy use,CO₂-emissions and various other pollutantsand resources. This article examines thetheoretical aspects of structuraldecomposition, in particular those concerningphysical flows and environmental issues.Furthermore, the article includes an extensivesurvey of empirical studies.

Coping with Technological Change: The Role of Ability in Making Inequality so Persistent

This study provides an explanation to the evolution of wage inequality over the last 30 years and supports this explanation with evidence. A faster rate of technological progress introduces new unknown elements at the workplace. The need to cope with the unknown accentuates the role of ability and thus increases wage inequality within and between education groups. Inasmuch as education is an irreversible investment project the rise in within group inequality BOOSTS UP the rise of between group inequality. Guided by this theory we turn to the PSID for evidence. Using parents' education to approximate child's ability we show the following set of results: (a) Controlling for education of the child, parents' education contributed much more in the 1980s to his wage growth than in the 1970s. (b) The correlation between the parents' and the child's education increases from the 1970s to the 1980s. (c) The return to college education for an individual with no ability rents did not change—it remains steady at the 23 percent. (d) Facts (a)–(c) CANNOT be attributed to the impact of parent's income. It is parents' education and not parents' income that is more relevant for son's economic outcomes in the 1980s.
