Economic Growth in Canada and the United States: Supply‐Push or Demand‐Pull?

Understanding the nature of structural change and the sources of economic growth of an economy, especially the relative importance of different industries, is essential for policy‐making. This paper estimates industry contribution to economic growth in both Canada and the United States. It argues that industry contribution should be evaluated on the basis of the performance of an industry in terms of creating economic value relative to other industries. In particular, it calls for the quantity and the price effects, which is consistent with real GDP in the chained‐Fisher index that values the industry more when its price rises and less when its price declines. This is an important departure from the traditional methodologies that consider only quantity effect. This paper shows that the contribution from demand‐driven industries is significantly more than the finding based on traditional thinking.

消费需求与经济增长关系的计量经济分析

消费需求是拉动经济增长的三驾马车之一,足以说明消费需求在经济增长中的重要地位.改革开放以来,伴随国民经济的快速发展和消费者收入的增加,我国的消费总量呈现出显著增加的趋势,消费结构得到不断的优化.本文基于计量经济学的基本理论,依据消费需求与经济增长之间的辨证关系,选用1978年以来我国经济发展和消费需求的32年数据,使用不同的计量经济方法,从经济增长的因素分析、经济增长对消费需求的影响和消费需求对经济增长的影响三个方面验证了消费需求与经济增长之间的数量关系和相互影响作用,同时利用格兰杰因果关系检验的方法确认了消费需求与经济增长之间互为因果的影响关系.数量关系的确立,为探求二者之间的变化趋势,进行科学决策提供了数量依据.

The use of open source internet to analysis and predict stock market trading volume

The objective of this paper is to evaluate the impact of information demand and supply on stock market trading volume. Few studies have demonstrated the role of Google search data in analyzing trading volume activity. In this study, we employ a proxy for information demand which is derived from weekly internet search volume. The latest is from Google Trends database, for 25 of the largest stocks traded on CAC40 index, between April 2007 and March 2014. We use news headlines as a proxy for information supply. We use Garch model to analyze and predict trading volume.The empirical results present new evidences. First, information supply has an impact on trading volume but information demand's impact is much more important. Secondly, by applying MCA to results found, it could be concluded that the impact of public information on transaction volume is conditioned by two elements: the firm and market news disclosure and the second element relates to the characteristics of the market participants, more precisely their news interpretations and their risk aversion. Thirdly, we used Chow structural break test to verify the stability of our model. We found that for securities with structural changes, information demand is the responsible variable of the change in our model. Finally, we found that information variables have a predictive power on transaction volume.This paper contributes to existing literature by incorporating open source internet-based data into the analysis and prediction of transaction volume. Using internet information about the stock market, which has appeared recently as an interesting research for financial empiricists, computer scientists and practitioners, will have a very important utility because quantifying demand and supply of information becomes possible.

中国农村金融组织体系发展研究

当前农村金融组织金融服务滞后,很大程度上是由于对农村金融需求发展的特点研究不够。研究表明：深入分析农村金融组织的现状,充分发挥农村金融组织在动员资金、配置资金、规避风险三方面功能,构建政策性金融机构、商业性金融机构、合作性金融机构和其他金融机构等多种形式并存、合理分工、功能互补、有序竞争的多层次的农村金融组织体系,可在一定程度上能满足农村金融需求的发展。     

马克思关于供求决定价格规律的假意识性质的交叉科学诠释

新古典经济学认为,价格由供求决定是达到资源最优配置的必要条件。可是,从交叉科学的观点看,新古典经济学的资源配置的优化性是有限的,因为在不利的工资-私人利润比率条件下,最广大人民群众的消费组合的优化性没有什么意义。而从数学的观点看,所谓供求决定价格是一个伪命题,供求均衡的条件最多不过是规定了一个对应关系,它无法决定价格;价格是由其他变量决定的。对于处于转型期的国家而言,价格是首先由社会根本制度决定的。社会根本制度是因,而价格水平是果。由此,我们论证了马克思在100多年前提出的供求决定价格规律假意识性质理论命题的科学性。
