用产品生命周期进行财务管理

本文扩展了产品生命周期模型，提出用产品生命周期进行财务管理的系统模型。在产品生命周期的每一阶段，应采取不同的财务策略。同时。应保持足够的战略柔性，适时修正已经制定的财务战略以最大化企业的利益和股东的利益。财务战略的制定和执行要从公司作为一个整体的角度来进行，应与公司的其它职能部门进行必要的协调以实现公司的目标。     

区位决策视角下的集群生命周期分析

本文在对当前产业集群生命周期研究述评的基础上,将集群周期划分为成长、成熟、衰退、再发展四个阶段,并从企业区位决策的视角对集群生命周期的不同阶段进行分析。然后通过考察企业区位决策因子的动态变化和集群区核心产业的区外出口量增长率、主导产业的企业数量、修正后的空间基尼系数来对生命周期阶段进行划分,分析不同阶段下政府的决策行为。

企业文化对知识型员工组织承诺影响的研究

为了探讨提高知识型员工组织承诺的有效路径,文章针对现有研究中的一些不足,提出了不同企业文化导向对知识型员工感情承诺及继续承诺影响的研究框架,从理论上探讨了员工导向文化与任务导向文化如何对知识型员工组织承诺产生影响,以期为企业提高知识型员工的组织承诺提供理论指导.     

基于产品生命周期的物流系统动态规划研究

由于在产品不同生命周期阶段市场竞争具有不同的特征,因此企业采取的市场战略也有较大的差别。应用物流系统的动态评价方法,研究了有效支撑企业产品市场竞争战略的物流系统应该具有的关键性特征,并在此基础上分析了如何组织企业内外部的物流资源,使得物流系统成本最小化的动态规划问题。

How to invest over the life cycle: Insights from theory

We analyse the state of the art in the field of life cycle portfolio choice, a recent strand of the literature on intertemporal portfolio selection. Life cycle models are designed to identify optimal savings and portfolio policies over the lifetime of investors. They can help to improve pension schemes by showing how these could be specifically tailored to the individual employee’s circumstances to overcome the ‘one-size-fits-all’ philosophy still prevailing in parts of the mandatory retirement savings system. To facilitate comparison, we first describe set-up, solution method and characteristic results for a basic model and then derive a general framework to classify existing contributions. We highlight the models’ strengths and weaknesses and assess their ability to resolve existing portfolio puzzles. Lessons from the literature are summarized and promising areas for further research identified. JEL classifications G11, D14, D91, H55     

Thermodynamics and process analysis for future economic scenarios

Economists are increasingly interested in forecasting future costs and benefits of policies for dealing with materials/energy fluxes, polluting emissions and environmental impacts on various scales, from sectoral to global. Computable general equilibrium (CGE) models are currently popular because they project demand and industrial structure into the future, along an equilibrium path. But they are applicable only to the extent that structural changes occur in or near equilibrium, independent of radical technological (or social) change. The alternative tool for analyzing economic implications of scenario assumptions is to use Leontief-type Input-Output (I-O) models. I-O models are unable to endogenize structural shifts (changing I-O coefficients). However, this can be a virtue when considering radical rather than incremental shifts. Postulated I-O tables can be used independently to check the internal consistency of scenarios. Or I-O models can be used to generate scenarios by linking them to econometric macro-drivers (which can, in principle, be CGE models). Explicit process analysis can be integrated, in principle, with I-O models. This hybrid scheme provides a natural means of satisfying physical constraints, especially the first and second laws of thermodynamics. This is important, to avoid constructing scenarios based on physically impossible processes. Process analysis is really the only available tool for constructing physically plausible alternative future I-O tables, and generating materials/energy and waste emissions coefficients. Explicit process analysis also helps avoid several problems characteristic of pure CGE or I-O models, viz. (1) aggregation errors (2) inability to handle arbitrary combinations of co-product and co-input relationships and (3) inability to reflect certain non-linearities such as internal feedback loops.     

产业集聚、技术创新与城市经济动力

构建一个基于企业内生创新的具有正反馈效应的城市经济动力系统,旨在阐明产业集聚、技术创新与城市经济的关系。产业集聚的确有利于创新的产生,但绝非必然,甚至有时还会由于知识拥挤导致经济停滞。技术生命周期理论可以帮助我们解释产业集聚与创新集聚间的关系。城市提供创新激励,然而因吸收能力不同企业创新绩效也存在差异,这是城市经济差异的重要原因。     

试论大学政治理论课的改革思路

在高等院校,思想政治理论课是维系马克思主义在意识形态领域的主流地位的重要工具。那么,目前政治理论课面临什么样的现实处境?应该如何改善政治理论课的现状。笔者根据在学生中的调查提出了一些个人观点。
