地区专业化、产业集中与经济集聚——对我国制造业的实证分析

以新经济地理学模型为基本理论框架,对我国各省区专业化水平、制造业各行业的集中程度和整个制造业的集聚程度进行了实证分析,结果显示1993—2003年间我国各省份的专业化水平呈显著上升趋势,制造业大部分行业集中程度提高,整个制造业集聚程度上升。在制造业各行业集中程度和整个制造业集聚程度的测算中,引入SP指数,结果显示这一指标的引进是非常必要的。     

Natural resources, capital accumulation and the resource curse

Early concern by economists for the effect of natural capital on economic growth gave way to complacency and neglect during the nineteenth century. Evidence has emerged, however, that since the 1960s the economic performance of low-income countries has been inversely related to their natural resource wealth. This relationship is not a deterministic one so policy counts. SEEA can help improve the policy and performance of resource-abundant low-income countries by reinforcing the rationale for the sound management of natural resources and also by providing an index of policy sustainability in the form of the net saving rate. This policy index, along with other measures such as a capital fund for sterilizing the rent, initiatives to increase the transparency of rent flows and the rigorous evaluation of alternative uses of additional public sector revenue can improve the efficiency by which natural resource rent is transformed into alternative forms of capital to sustain rising social welfare. Chad and Mauritania provide case studies to illustrate how SEEA and net saving can be used to diagnose policy failure and improve economic performance.     

Endogenous structural change and crisis in a multiple time-scales growth model

The slow and endogenous twist of economic macro-structure makes up an important evolutionary feature of capitalist economies, and may be at the root of structural crisis. In this line, a Goodwinian growth model with increasing returns and profit-sharing that tries to picture a simple scenario of the seventies crisis is considered. It is shown that the exhaustion of the Kaldor-Verdoorn “productivity law” can entail, in a nonlinear framework, a “catastrophic” bifurcation from a “high” to a “low” growth path. Slow/fast dynamical systems then allow one to formalize a multiple time-scales dynamics where the growth path is shaped by the structural framework in which it takes place, but has also a long -un feedback. Structural change and crisis appear as long term and endogenous outcomes.

论平衡记分卡的"不平衡"

国内对平衡记分卡的认识,与发达国家相比还存在很大差距。许多人还没有真正认识到平衡记分卡的含义和用法,仅仅追求形式,使平衡记分卡成为组织"看起来好看,用起来无用的装饰品"。本文提出根据企业实际情况建立精简的"不平衡"记分卡的观点,借以与大家进行深入讨论。     

数量指标和质量指标理论与应用评析

在各类《统计学》教科书中,对数量指标和质量指标概念的解释不大一样,但基本的含义却是相同的。两者从概念上区别并不困难,也容易理解,但在对一些特殊问题的分析时,却不易把握,特别是在比较复杂的统计分析中,那就更不容易做出准确的判断了。怎样才能对数量指标和质量指标的应用做出科学的评价和分析。本文拟就这方面的问题做些初步探索。     

景区环境控制指标体系研究--以三峡库区为例

根据景区环境控制的原则,本文从生态环境、空间环境、设施环境以及社会环境四个方面建立起三峡库区景区环境控制指标体系,并以重庆库区为例对各项指标的控制标准进行了较为详细的论述.     

工序能力指数的新定义及其应用

本文简述工序能力指数的传统定义及其不合理性,其根源是偏移系数的定义有缺陷。改进偏移系数的定义后,将使工序能力指数的定义更加科学、合理,进而给出不合格品率p与C_p、k之间的计算公式和常用数值表,供企业应用时选用。     

营销风险预警指标体系及综合评价方法

文章从影响营销活动的各类因素入手,根据其内容、特点及分类,构建了营销风险的预警评价指标体系;从定性与定量相结合的角度出发,应用多级模糊综合评判法对营销风险进行量化评价,对定性分析指标采用专家调查与模糊统计相结合的方法,对定量指标的处理则引入模糊数学的方法,从而实现定性指标与定量指标的结合。     

全面小康社会指标评价体系

全面小康是涉及个人、企业和社会三维一体的小康。社会的小康由企业和个人的小康组成,而企业又是个人小康的主要载体。因此,研究个人、企业和社会各自的全面小康标准对于实现本世纪头20年全面建设小康社会的目标十分必要。衡量小康社会发展程度需要配套标准,构筑这些标准,建立相对健全的评价指标体系,是实施全面小康战略的迫切需要。
