中国的工业改革与效率变化-方法、数据、文献和现有的结果

全要素生产率是理解经济增长的方式和结构的重要指标之一,中国的工业改革正好为经济学家关注和考察不同所有制的企业形式以及改革政策对生产率变动的不同影响提供了丰富的经验基础。在1978年开始的旨在向市场经济转型的中国经济体制改革正在彻底地改变着它的工业部门面临的市场结构和工业组织,并不断造就着一个与世界经济更加融合的制造业部门。新的和更有竞争力的工业部门在竞争中不断获得了高速增长和扩张的机会,使得中国工业部门的生产率改善主要依赖着非国有企业的成长和它的活力。中国工业改革的成就不是挽救了国有企业,而是收缩了国有企业部门的"战线",诱致了一个非国有的新兴工业部门的崛起。     

控制费用为“取最大”形式的可控排序问题

本文讨论了一类新的加工时间可控的单机排序问题,其目标函数为正则函数与最大不满意程度函数之和,不满意函数刻划了对工件实际加工时间偏离其额定加工时间不满意的程度,本文对这类问题提出了几个多项式算法。     

MANAGING VENDOR INVENTORY IN A DUAL LEVEL DISTRIBUTION SYSTEM

Collaborative arrangements among members of the supply chain have received a great deal of interest in recent years as a means of reducing costs. One such arrangement is vendor managed inventory (VMI). VMI allows the vendor to make decisions concerning the quantity and timing of deliveries to the retailer. Such an arrangement offers the potential of a more efficient supply chain by removing the negative effects of retail ordering policies. A thorough review of the literature was conducted to identify factors likely to impact the performance of a VMI partnership. Computer simulation was used to study the effects of these factors from both the vendor's and retailer's perspectives. The results lend insight into the performance of VMI and guidance for managers as to the environments in which VMI is most effective.

我国A股、B股市场并轨的前景探析

B股市场的前途问题是一个困扰市场参与者的主要问题,而前途的不明朗源于B股市场定位的困惑和功能失调。筹资功能方面,1991～2004年12月B股市场通过股票发行总计筹资50.03亿美元,通过配股筹资3.27亿美元,而同期A股市场对应的数据是5695.7亿元和2276.74亿元,而且最近3年B股市场的     

上海服务业发展水平的国内与国际比较

本文首先比较了上海与国内18个副省级及以上城市服务业总体发展情况，将上海服务业各行业增加值及服务业内部构成与北京、天津、重庆、广州和深圳5个国内经济发展水平较高的城市进行了比较，采用“区位熵”的方法衡量了上海服务业各行业的比较优势。其次，将上海服务业发展水平与若干国际大都市进行比较，得出上海服务业仍处于较低的发展水平，尚未进入以知识型、生产型等高级服务业为主导的发展时期，大力发展现代服务业是上海当前的现实选择的结论。

Are Expected Inflation Rates and Expected Real Rates Negatively Correlated? A Long‐Run Test of the Mundell‐Tobin Hypothesis

Some empirical evidence suggests that the expected real interest and expected inflation rates are negatively correlated. This hypothesis of negative correlation is sometimes known as the Mundell‐Tobin hypothesis. In this article we reinvestigate this negative relation from a long‐term point of view using cointegration analysis. The data on the historical interest rate on T‐bills and the inflation rate indicate that the Mundell‐Tobin hypothesis does not hold in the long run for the United States, the United Kingdom, and Canada. We also obtain similar results using the real interest rate on index‐linked gilt traded in the United Kingdom.     

Commodity currencies

This paper looks at real exchange rate behavior by focusing on three OECD economies (Australia, Canada, and New Zealand) where primary commodities constitute a significant share of their exports. For Australia and New Zealand especially, we find that the US dollar price of their commodity exports (generally exogenous to these small economies) has a strong and stable influence on their floating real rates, with the magnitude of the effects consistent with predictions of standard theoretical models. However, after controlling for commodity price shocks, there is still a purchasing power parity puzzle in the residual. The results here are relevant to developing commodity-exporting countries as they liberalize their capital markets and move towards floating exchange rates.     

Modernization in Mainland China:

A bstract . After 1949, mainland China, a developing socialist country, adopted an inward-looking policy with emphasis on self-reliance and economic independence. However, in their drive for economic reform that began in 1978, mainland China drifted to the new doctrine of "taking self-reliance as the principal means and external assistance as a subsidiary." A version of the two-gap model is constructed to test the hypothesis that both domestic capital accumulation and foreign capital inflows affect economic development in mainland China , the latter being an indicator of modernization. Due to insufficient data, pooled cross-section and time-series data for the period 1984–1986 are employed. The quantitative evidence suggests that foreign capital inflows, instead of domestic capital accumulation, have importantly affected the modernization drive of mainland China. The recent political turmoil in mainland China has slowed down foreign capital inflows which in turn may retard its modernization.
