中国松香出口创汇状况变迁原因及对策初探

通过对我国自1994年以来松香出口创汇量的数据分析,指出了中国松香行业存在"多出口,少得汇"的问题。分析了问题产生的主要原因是市场供求关系失衡、无序竞争和缺乏有力的宏观调控及约束管理机制,并探讨了新的对策。     

Labour market competitiveness and foreign direct investment: The case of Malaysia,Thailand and the Philippines

This article investigates whether labour market competitiveness affects the inflows of foreign direct investment (FDI) into the ASEAN economies Malaysia, Thailand and the Philippines. The analysis is based on a regression model using time series data on FDI, wages, the labour force, skills, R&D expenditure, the interest rate and several variables critical for economic development. The study shows that the labour market determinants differ between countries in terms of their role in FDI inflows. Thus analysis results suggest that, with regard to labour market competitiveness, different countries may require different policy recommendations in order to attract FDI inflows into their countries.Received: 2 October 2002, Accepted: 24 May 2003, JEL Classification: J240, J310, R230

Strategic capital budgeting: asset replacement under market uncertainty

In this paper the impact of product market uncertainty on the optimal replacement timing of a production facility is studied. The existing production facility can be replaced by a technologically more advanced and thus more cost-effective one. We take into account strategic interactions among the firms competing in the product market by analyzing the problem in a duopolistic setting. We calculate the value of each firm and show that i) a preemptive (simultaneous) replacement occurs when the associated sunk cost is low (high), ii) despite the preemption effect uncertainty always raises the expected time to replace, and iii) the relationship between the probability of optimal replacement within a given time interval and uncertainty is decreasing for long time intervals and humped for short time intervals. Furthermore it is shown that result ii) carries over to the case where firms have to decide about starting production rather than about replacing existing facilities.

论我国股市道德的"蛛网理论"

当前我国股市正在快速发展中,股市道德问题也日益为世人瞩目。股市道德及不道德力量同股市欺诈等问题具有相互对应关系,这就形成了一个制衡机制;在具体的运行中,其制衡机制可以两种依道德曲线的斜率不同,而呈封闭、收敛和发散三种"蛛网"运行状态;依此原理,以德治市的关键是要遏制"发散的蛛网"、争取股市运行于"收敛的蛛网"状态。

通过分析中东地区对石油资源的控制与反控制斗争形势,指出美伊战后中东石油市场的三大走势是：①战后伊拉克石油市场将重新洗牌;②美英“倒萨”,企图主导中东石油资源;③油价将总体走高、短期下降并剧烈震荡。     

DualMiner: A Dual-Pruning Algorithm for Itemsets with Constraints

Recently, constraint-based mining of itemsets for questions like find all frequent itemsets whose total price is at least $50 has attracted much attention. Two classes of constraints, monotone and antimonotone, have been very useful in this area. There exist algorithms that efficiently take advantage of either one of these two classes, but no previous algorithms can efficiently handle both types of constraints simultaneously. In this paper, we present DualMiner, the first algorithm that efficiently prunes its search space using both monotone and antimonotone constraints. We complement a theoretical analysis and proof of correctness of DualMiner with an experimental study that shows the efficacy of DualMiner compared to previous work.     

考虑风险因素的两市场购电优化分配问题

不同国家和地区的电力市场通常根据自己的特点采用不同的市场模式,但无论在何种模式下,都存在一个类似于长期市场和短期市场的结构。电力市场中的购电商通常要在长期市场和短期市场进行电力交易,而其中的关键问题之一是如何针对本公司的情况,根据市场信息,寻求一种购电策略,优化两个市场的购电分配,使总的购电费用和风险尽可能得小。文中对这一问题进行了建模和讨论,针对由总费用和风险共同构成的目标函数,研究了两个市场的购电问题,给出了问题的解析解并针对实际市场数据进行了数值仿真,该问题的研究结果不仅有利于购电商分配不同市场的购电量,也为购电商进一步构造竞标曲线奠定了基础。
