We study the effect of ownership structure on firm performance of the ShenZhen SME Board firms by constructing the complex stochastic frontier production function in the period from 2006 to 2008. The evidence indicates that the ownership concentration of the SMEs has significantly positive relation with the firm performance, but the fraction of the biggest shareholder is negatively related to performance. Furthermore, there is no significant difference in firm performance among the shareholders of state, legal person, individual and foreign investors; the fraction of the tradable share, the fraction of shares hold by the managers and the research and development input have no significant impact on firm performance. Lastly, SMEs tend to finance more by equity than by debt .

文章运用引力模型的“多国模式”,对1998-2008年中国和东盟六国之间,以及他们与美国、日本、德国、韩国、澳大利亚的双边贸易流量面板数据进行分析,从而评估CAFTA的建立对区内贸易的扩大效应.

The technical efficiency,the technical progress and the change of total factor productivity of Chinese service industry under the impact of FDI can be examined by building the complex stochastic frontier production model under the impact of FDI,by using the panel data collected in China's 30 provinces(municipalities) from 1992 to 2007,and by resorting to the estimation method of simultaneous maximum likelihood.Empirical research shows that FDI plays a role in promoting the technical efficiency and technical progress in service industry,of which the technical efficiency improves with the time.The increase of the total factor productivity varies in different areas,and among the top 3 of high increase are eastern coastal provinces and cities like Guangdong,Jiangsu and Shanghai.

本文从全球贸易的数据资料出发,通过设置变系数面板数据引力模型对中国大陆、台湾和香港两岸三地1987年至2004年间的贸易关系,尤其是对两岸三地是否存在贸易区块及其动态变化、两岸三地两两之间的贸易依存关系进行了实证考察。研究结果表明:两岸三地的贸易明显高于该区域内经济水平、市场规模和地理位置下所应有的正常水平,并且这一区块的作用在中国加入WTO后进一步增强;香港在两岸三地的贸易关系中起着中介的作用;中国大陆虽然从1978年开始进行改革开放,但对世界贸易流量增长的突显作用却是在1990年代以后才开始显现。

Under the framework of information disclosure of listed companies, this paper conducts an empirical analysis on the relationship between announcement of executive health information in China's listed companies, especially disclosure of the death of the executives of listed companies on their posts with the company's stock price behavior. Article selected 47 death announcements of executives in the Shanghai and Shenzhen A-share companies which traded from 2001 to 2008 for the study samples and conducts an empirical study on stock retums after the disclosure of information.Studies have shown that disclosure of executive health information had a significant impact on stock price and the health information of executives of listed companies are in line with material of accounting information.The article also proposes suggestions to related the information providers, users and regulatory authorities.

This study evaluates the performance of price limits mechanism in Shanghai stock market from three aspects: the volatility spillover hypothesis, the delayed price discovery hypothesis, and the trading interference hypothesis. The results show that the price limits mechanism in China is ineffective. This study finally proposes that the price limits in China should be relaxed and asymmetry.

We proposed a censored-SS model for estimating time-varying betas under price limits which incorpo- rates the censored effect into the SS model by taking into account the effects of price limits.Using the daily data of Chinese Stock Exchange in 1997 to 2001,the time-varying betas yielded by the censored-SS model show that in China the systematic risks of large firms(small firms)tends to increase(decrease)with an increase in aggre- gate market volatility.To demonstrate that the censored-SS model yields more accurately betas,we compare the RMSE in-sample of the market model,the SS model and the censored-SS model.The results support the cen- sored-SS model.

在现代市场经济体制中,银行业作为经营货币的特殊行业在社会资源的配置过程中起着重要的作用.由于银行业相对于其他行业而言具有特别显著的外部性,世界各国普遍对银行业进行了严格管制.一般来说,对一个行业的管制可分为市场结构管制和市场行为管制.市场结构管制是对行业的进入和退出进行的控制,其目的是保证该行业能保持良好的市场结构,防止过度垄断和过度竞争的情况出现:行为管制是针对厂商的市场行为所采取的管制措施,如价格管制、广告管制以及最低质量标准等.本文的研究主要集中于我国银行业市场结构管制中的市场准入问题.

Export credit insurance (ECI) is the WTO-recognized an d world-popular policy means that aims to support domestic export corporations. The risk fund appropriated by China's Finance Ministry now can't satisfy the in creasing need of ECI and will then affect the ECI's promoting-export functions. This paper first forcasts China's export volumn and ECI insured amount in the n ext few years on the basis of the factors that affects ECI risk fund. Then the a ppropriate numer of China's ECI risk fund is determined in order to provide basi s for the relative desion institutions.
