Advertising, Its Determinants, and Market Structure

This study derives a formal model of firm advertising behavior and applies it to the industry level to figure out the relationship between advertising and market structure. The firm advertising model shows that both consumer preference andfirm-specific advertising competence jointly determineprofit-maximizing advertising intensity. At the industry level, advertising intensity is represented multiplicatively by consumer preference and a measure of market structure, which reflects the joint distribution of the levels of advertising competence and market shares among firms. The new market structure measure suggests that those single-dimensional measures of market structure such as seller concentration and the Herfindahl index are inadequate in explaining interindustry differences in advertising intensity, and that the long-debated advertising-concentration relationship differs depending primarily on the appropriability of advertising. An empirical analysis of 426 five-digit Korean manufacturing industries shows that an inverted U-shaped relationship between the Herfindahl index and industry advertising intensity is observed for consumer goods industries but a lazy J-shaped relationship for producer goods industries.     

顺酐国内外生产现状与发展趋势

世界顺酐工业正由苯法合成向正丁烷法合成转变，正丁烷法的生产能力已占顺酐总生产能力的80%，我国顺酐消费需求发展迅速，生产工艺仍以苯法为主，我国应立足于苯法生产，并做好向正丁烷法转变的技术准备，不断改进工艺淘汰小规模不经济顺酐装置，增强竞争能力。     

社会互动、相对财富关注及股市参与

已有的研究表明,社会互动推动了家庭的股市参与。依据社会互动推动家庭股市参与不同机制的理论基础和预测,本文对不同的具体机制进行了研究,我们发现在局部品支出比例高、收入分布集中度高的区(村),社会互动推动股市参与的作用更显著,这与外部习惯模型及相对财富关注模型的理论预测一致,事前对局部稀缺品的关注使得家庭的股市参与存在外部性。社会互动推动股市参与其他机制的理论预测则未得到数据的支持。     

股市波动、金融政策和宏观经济关系研究——基于因子VAR模型

通过因子分析从诸宏观经济变量中提取了金融政策因子和宏观经济状态因子,建立了基于VAR的股价波动、金融政策和宏观经济三变量回归模型。研究表明：金融政策影响股价的表现,而宏观经济状态对股价、股价对金融政策和宏观经济状态的影响均不显著;基于标准差的VAR（5）模型相对于基于收益率的VAR（3）模型能更好地刻画股市波动与金融政策、宏观经济三者之间的关系。     

对加入WTO后"以市场换技术"的思考

“以市场换技术”是20世纪80年代中后期以来我国吸引外国直接投资的重要目标之一。本文首先简要回顾了中国在加入WTO前的“以市场换技术”战略,在此基础上,分析了在加入WTO后“以市场换技术”的政策环境和外资在华行为的变化以及国际产业发展呈现出的新趋势,最后对如何促进“以市场换技术”提出了若干建议。     

The Research of the Construction Time on City Infrastructure Projects

The project construction time is not sufficiently considered in the decision-making procedure of the extant city infrastructure project all over the world. From the principle to increase benefit from the investment, the paper discusses the influence of construction time on benefit from investment, the condition of the optimal construction time, the method to confirm the optimal construction time, etc., under the increases of market demand, the paper establishes mathematics model between the construction time and the project benefit, and the model involves the project age, the construction time, the capital cost, the market demand, the discount rate and so on. Finally, the paper quantitatively analyzes the influence characteristics and degrees of construction time to the project profits, and the method to determine the optimal construction time of a project under different market demand .To emphasize that, the paper researches on Chinese cases, but, the conclusion put forward has the widespread significance to the time choice on city infrastructure project of other countries.

Bilateral Trade Balances: Evidence from Malaysia*

This study examines the impacts of real exchange rates on the bilateral trade balances of Malaysia with the USA, Japan and Singapore. The results for the long‐run cointegrating vectors show that depreciation or devaluation of real exchange rates will improve bilateral trade balances. In the short run, there is some evidence of the J‐curve phenomenon. Changes in real money supply contribute greatly to changes in real exchange rates. Generally, changes in real exchange rates contribute significantly to changes in bilateral trade balances. Monetary policy can be used to influence bilateral trade balances.     

扩大内需导向下的我国纺织产业转移研究

纺织产业是我国传统的劳动密集型产业,不但在满足国内需求、扩大就业等方面发挥着重要作用,也是我国少数具有国际竞争优势的产业之一。国际金融危机发生以来,国内外经济形势发生了一系列变化,不但给我国纺织产业增加了压力,同时也是调整产业结构与拓展发展空间的契机。因此,文章提出在国家积极扩大内需市场导向下,我国纺织产业应通过产业转移,调整区域布局,推动跨区域纺织产业链的形成与产业整体升级。
