我国工业企业技术资产利润贡献份额及影响因素研究

本文以2007～2009年制造业A股上市公司为样本,运用改进后的柯布-道格拉斯生产函数,通过实证研究测算了工业企业各项资产的相对效率及技术资产的利润贡献份额。研究结果表明:技术资产的利润率要高于固定资产及人力资产;技术成熟度不同、规模不同及所有权性质不同的行业技术资产利润贡献份额不同。企业应优化资本配置,提高投资效率。     

皖江城市带与长三角地区优势要素的识别与耦合

皖江城市带的发展思路就是与长三角地区通过产业转移等互动发展。运用EF指数分析皖江城市带和长三角地区的要素禀赋状况,发现皖江城市带在劳动、资本、农产品、教育、研发和旅游等要素上具有比较优势,而长三角地区在研发、通讯、旅游等要素上具有比较优势。并针对不同的要素特点,提出了不同的要素耦合方式,对皖江城市带承接长三角地区的产业转移提出了建议。     

不同剂型硝苯地平治疗高血压的药物经济学评价

目的评价抗高血压药硝苯地平临床常用三种不同剂型治疗高血压的临床效果和经济效益。方法选择90例高血压病患者随机分为三组,每组30例,分别口服硝苯地平普通片、缓释片和控释片治疗,并进行药物经济学分析。结果服药8周后各组患者血压均有明显下降,其中普通片、缓释片和控释片治疗高血压总有效率分别为93.33%、93.33%、96.66%,不良反应发生率分别为10.0%、6.6%、0.0%,成本-效果比分别为0.02、0.40、2.96,控释片相对于普通片的增量成本-效果比为85.43。结论硝苯地平缓释片虽其消费成本不是最低,但服法简单,副作用较少,综合评价是硝苯地平临床常用三种剂型治疗高血压的最佳剂型,特别适用于基层医院。     

Long‐Term Growth in Housing Prices and Stock Returns

A firm's long‐term stock returns are negatively related to past growth in housing prices in the state where the firm is located. The housing price effect is persistent and robust to controlling for the long‐term stock return reversal effect, changes in mortgage interest rates across the states, cyclicality in housing prices and overall local economic conditions. There is no evidence that extant asset pricing models can adequately explain the effect. The study discusses potential explanations for, and the implications of, the cross‐regional housing price effect.

Is There Any Gender effect on the Relationship Between Service Quality and Word-of-Mouth?

Gender is an important discriminator of market segment in the service industry. When considering the word-of-mouth (WOM) effect as a powerful tool of the market channel, it is vital to understand the characteristics of gender and to establish different strategies for providing services depending on how males and females deliver their perceptions of service quality to other people. This study examined the differential role of gender on the relationship between core/relational service qualities and WOM. Data from 277 travelers who have stayed in midscale hotels with Food and Beverage were analyzed. The results suggest there are within-gender differences in the effect of service qualities on word of mouth, but there is no significant difference across the genders.     

Tour Guide Management in Hainan,China: Problems,Implications and Solutions

There have been few efforts made to identify the positioning of exhibition host countries or cities, even though studies on the positioning of convention host destinations have been popular. Thus, the aim of this study was to assess the positioning of exhibition cities as perceived by a sample of exhibitors who participated in exhibitions held in Hong Kong. A total of 304 questionnaires were collected at the PATA Travel Mart 2006, the Hong Kong Jewelry and Watch Fair, Aircraft Interiors Expo ASIA 2006, MIPIM Asia 2006, and Electronic Asia 2006. The results of this study found that there is a strong competition between major exhibition host cities in Asia, including Hong Kong, Beijing, Shanghai, Singapore, Seoul and Tokyo. The respondents showed the highest preference for Hong Kong and Singapore as an exhibition host destination.     

Total Factor Productivity Assessment of Tourism Industry: Evidence from China

This paper adopts the Malmquist Index and panel data model to measure and test the spatial–temporal evolutionary characteristics and the factors that affect total factor productivity of China's tourism industry from 2001 to 2009. The results show the following: there is a trend of growth in the total factor productivity of China's tourism industry, and technological progress is the dominant factor that affects total factor productivity changes, which indicates that the growth pattern of China's tourism industry has changed from a pattern driven by input factors to a pattern driven by technology; the spatial pattern of the total factor productivity of China's tourism industry has changed from a spatial pattern dominated by provinces with a low productivity to a spatial pattern dominated by provinces with a high productivity; the total factor productivity of China's tourism industry is mainly affected by the levels of economic and service industry development.     

Impact of exchange rate regime reform on asset returns in China

Employing monthly data over the period 1999–2010, this paper examines the impact of China's exchange rate regime reform in July 2005 on three major asset markets: house, land, and stocks. We test whether the reform, which switches from a fixed exchange rate regime to a managed floating one, has brought forward structural changes to asset return dynamics. The results suggest that the exchange rate regime switch exerted the most significant impact on house and land returns at the national level, in terms of both returns and their volatilities. In contrast, its impact on China's stock market was moderate, with no structural change being detected in its returns and only weak structural change being found in the dynamics of its volatility. We also find that in comparison with other popular explanatory variables, broad money supply and inflation have the largest explanatory power on housing and land returns in China after the policy reform.
