以设计为龙头的工程总承包建设模式推动MgO混凝土为拱坝新技术的应用

就新技术MgO混凝土拱坝与碾压混凝土拱坝的不同之处作了对比。论述了广东长沙拱坝成功应用MgO混凝土筑坝的意义，认为该顶新技术又一次能在2001年1季度末开始浇筑的贵州沙老河拱坝应用，是由一机制的原因起了作用，即：以设计为在龙头的总承包建设模式，可以对大型新技术的应用起推动作用。     

我国炼油工业应实行改造与新建并举的方针

目前我国炼油工业的生产能力，特别是加工中东含硫油的能力严重不足，为适应国民经济发展的需要，扩大炼油能力十分必要，根据测算，2010年我国炼油工业的加工量应达到3亿吨，2020年达到4．5亿吨，若按开工率90％计，则2010年我国炼油能力应达到3．3亿吨，2020年达到5亿吨，因此，从现在开始的10年内，需新增炼油能力1亿吨左右，在下一个10年，即2010至2020年，还需新增能力1．5亿吨，根据我国国情，因地制宜，充分利用现有装置潜力通过技术改造来发展炼油工业是十分必要的，但是大型，先进，一体化是我国炼油工业今后发展的主要方向，兴建新厂可采用先进的工艺技术和新的管理机制，取得较高的经济效益，因此，我国炼油工业的发展实行技术改造与兴建新厂并举的“两条腿走路”的方针。     

The Wealth Effect of Domestic Joint Ventures: Evidence from Taiwan

This study presents important international evidence by examining the wealth effect of domestic joint ventures by Taiwanese firms. In opposite to United States evidence, we find that announcements of domestic joint ventures by Taiwanese firms are, on average, associated with significantly negative abnormal stock returns. We also find that the stock market response to announced domestic joint ventures is significantly positively related to the announcing firms' investment opportunities, size of investment and debt ratio, and is significantly negatively related to the business relatedness variable. In contrast, free cash flow, firm size, relative firm size and managerial ownership are found to have no significant power in explaining the market response. Our results support the investment opportunities, synergy and complementarity hypotheses as well as a broad interpretation of the free cash flow hypothesis, but reject the absolute size, relative size and alignment-of-interests hypotheses. This study makes valuable contributions to the literature by providing the first direct evidence on the role of investment opportunities, synergy and alignment-of-interests in explaining the wealth effect of domestic joint ventures

Wage and Price Inflation in Poland in the Period of Transition: The Cointegration Analysis

The paper focuses on the long run relationships between wages, prices and labour productivity in the Polish economy by applying recent developments in the field of multivariate cointegration analysis. We followed modeling strategy which is suggested by Greenslade et al. (1999) and present all stages of the analysis which leads to the fully economically identified system of equations representing long run relationships. The investigation is based on the quarterly data from 1992.1 to 1999.2 which covers the period of transition of the Polish economy from the centrally planned system towards the market one. Basing on the empirical results we can argue that wages (costs) were one of the main forces driving inflation in Poland during that period. Also labor productivity proved to be stimulated by the increase of the real wages. On the other hand the hypothesis concerning the relationship between wages and unemployment was rejected by the data.     

基于更新理论的产品保修策略模型

产品价格的确定不仅取决于生产成本 ,还应包涵服务成本。非价格竞争下 ,产品保修是售后服务的主要内容。本文运用更新报酬理论 ,建立了产品保修策略模型。模型表明 :在消费转型时代 ,只有引入产品的差异性、降低生产成本、提高产品质量、延长产品寿命、制订合适的保修策略 ,才能保障合理的厂商利润 ,有效刺激需求。
