中国区域城市联盟计划运行不畅及其成因——以“苏锡常”城市联盟为例

一、引言 1980年代以来,伴随着经济全球化,新的劳动地域分工在世界范围内延伸,后工业社会的经济组织关系发生了巨大的变化,城镇区域化、区域一体化日益成为全球发展的趋势,并呈现出复杂的新格局.然而,在谋求区域经济一体化的同时,如何采用适当的地域空间组织模式协调地域内各地区的共同发展,却成了世界范围内共同关注和急需解决的问题.     

The influence of family ownership on SME performance: evidence from public firms in Taiwan

The relationship between family ownership and firm performance has gained increased attention in the business strategy and financial economics literature. Most existing studies use large companies as the research sample; studies that explicitly investigate the influence of family ownership on the performance of small- and medium-sized enterprises (SMEs) remain sparse. This study raises this issue explicitly by investigating the influence of founding-family ownership on the return on assets and Tobin’s q of 341 public SMEs in Taiwan, during the period of 2002–2006. It emerges from the data that family ownership is prevalent and substantial in Taiwan, representing half of the public SMEs and accounting for more than 11 percent of their outstanding equity. It was found that the influence of family ownership on SME performance is positive and significant. Overall, the results suggest that family ownership is an effective organizational structure for SMEs in Taiwan.     

Forecasting tourism demand with ARMA-based methods

The forecast of tourism volume in the form of arrivals is of special importance for tourism and other hospitality industries because it is an indicator of future demand, thereby providing basic information for subsequent planning and policy making. In this paper, three univariate ARMA-based models are applied to tourism demand, as represented by the number of world-wide visitors to Hong Kong, Japan, Korea, Taiwan, Singapore, Thailand, the Philippines, Australia and New Zealand. The study employs both monthly and quarterly time series generated from nine principal tourist destinations in Asian-Pacific region in the forecasting exercise to ensure the reliability of the forecasting evaluation. Forecasting performance based on disaggregated arrival series in a particular destination is examined as well. The general impression is that the ARMA-based models perform very well and in some cases the magnitude of mean absolute percentage error is lower than 2% level.     

Asset Pricing Specification Errors and Performance Evaluation

Many evaluation techniques typically measure performance asdeviations of average returns on actively managed funds fromthose predicted by some asset pricing model. Empirical evidence,however, has so far suggested that all asset pricing modelslack empirical support, implying that the models contain mis-specificationerrors to various degrees. Evaluating mutual fund performancerelative to any of these models thus becomes problematic. Inthis paper, we propose an approach to performance measurementthat emphasizes minimizing explicitly the pricing error associatedwith an asset pricing function which is employed to computeperformance measures. This approach is henceforth called theminimum specification-error (MSE) method. We also discuss thestatistical properties for implementing MSE performance measure.To demonstrate the significance of the pricing error confoundedin evaluation measurement, we contrast our methodology withthe Grinblatt and Titman (1989) period weighting approach andwith the empirical implementation of Chen and Knez (1996). Wefind that the greater the pricing error of passive assets, thelarger the performance measures. Given the average pricing errorgenerated from a collection of 163 diverse passive portfoliosused in this analysis the performance values assigned to a largenumber of the funds become statistically and economically insignificant.     

环境质量对居民幸福感的影响——从追求健康水平的消费动机出发

采用世代交叠模型(OLG)分析框架,研究了环境质量对居民幸福感的影响机制,即追求健康水平的消费动机,并利用CGSS2010年住户调查数据进行实证分析。结果显示:无论居民是否关注环境问题,环境污染越严重,家庭消费支出越高;环境污染越严重,关注环境问题的居民的幸福感越低;环境污染是否严重不会改变不关注环境问题的居民的幸福感;居民的环保意识不会影响其环保意愿,但会影响其环保支出意愿,不关注环境问题的家庭有"搭便车"倾向;不同区域、不同污染类型的环境问题对居民幸福感的影响存在差异;收入差距会改变人们的环保行为。     

R&D intensity,firm performance and the identification of the threshold: fresh evidence from the panel threshold regression model

This article tests whether there is an optimal level of research and development (R&D) intensity at which point a firm is able to maximize its performance. An advanced panel threshold regression model is employed to investigate the panel threshold effect of R&D intensity on firm performance among publicly traded Taiwan information technology and electronic firms. The results confirm that a single-threshold effect does exist and show an inverted-U correlation between R&D intensity and firm performance. This article demonstrates that it is possible to identify the definitive level beyond which a further increase in R&D expenditure does not yield proportional rewards. Some important policy implications emerge from the findings.     

基于DEA模型的视角对我国商业银行效率的实证分析

基于2004年的数据,运用数据包络分析方法,对我国13家全国性商业银行的效率进行了测度.实证研究的结果表明我国商业银行显示出了较高的纯技术效率,但总体效率和规模效率较低,国有商业银行普遍处于规模递减阶段,而股份制商业银行基本处于规模不变和递增阶段.     

外资开放、市场分割与产业升级——基于双循环新发展格局视角的探讨

文章首先通过定量识别《外商投资产业指导目录》，构造出我国外资开放度指标，然后，采用价格法测算了我国省际地区市场分割程度，同时借助贸易增加值核算框架测度了我国各省市制造业细分行业的产业升级；在此基础上，将交互模型与非线性模型相结合，实证考察了市场分割视角下外资开放对产业升级的非线性影响。研究发现：第一，外资开放与产业升级之间存在"倒U型"关系。第二，市场分割的弱化会对外资开放与产业升级之间的"倒U型"关系起到缓解，甚至翻转的作用，特别是在外资开放程度较高时，外资开放对产业升级的抑制作用会随着市场分割弱化而得以缓解，甚至转变为促进作用。换言之，我国在持续深化外资开放以推动产业升级过程中需要配合统一的大市场。第三，在解决内生性问题、替换指标、加入更多控制变量以及剔除部分样本之后，结果依然稳健。上述研究表明，构建"双循环"新发展格局是进一步推动我国产业升级，实现高质量发展的重要战略选择，而打破市场分割促进以统一大市场为基础的国内大循环的畅通是当前阶段重要的突破口。
