The major determinants of logistic performance in a global perspective: evidence from panel data analysis

The global logistics industry has grown significantly and logistics has become an important sector of the business economic system and a major global economic activity in recent years. Logistics activities accelerate economic and productivity growth. Efficient logistics is also important to a country’s competitiveness and source of employment. The purpose of this paper is to uncover and understand the major determinants of logistics performance (LP) to further lift the LP of countries. Using unbalanced panel data of 93 selected countries from 2007 to 2014, the present research attempts to critically investigate the major determinants of LP. In estimating the model, this study prefers to use static panel data approach owing to limited data. The findings of the present study reveal that (a) countries with low level of corruption and stable political environment are likely to yield a high level of LP; (b) improvement in resources supply such as infrastructure, technology, labour, and education also have a significant positive effect on LP. Therefore, institutional reforms and upgrading resources will effectively accelerate LP.     

茶产业发达地区茶农选择茶叶销售渠道的影响因素分析——基于福建安溪实证

以福建省安溪县茶农问卷调查数据为基础,利用二项Logistic模型对茶农选择茶叶销售渠道的影响因素进行计量分析。研究表明,茶农户主特征的年龄对茶农选择渠道的影响不显著;茶农户主是否是村干部对茶农自家开茶叶店有显著影响;茶农是否参加茶业合作组织对茶农选择茶业合作组织影响显著;茶叶收入占家庭收入的比重0~25%、26%~50%对茶农自家开茶叶店有显著影响,51%~75%对茶农选择茶叶经销商影响显著;农户到最近茶叶交易市场的距离≤3 km,对茶农选择茶叶经销商和茶叶批发市场这2个渠道影响显著。     

Contemporary Extensions of the Rasch Model

This paper will introduce, discuss and illustrate two contemporary extensions of theRasch model: the one parameter logistic model (Verhelst and Glas, 1995) and theMultidimensional Rasch model (Hoijtink et al., 1999). Using data with respect tothe measurement of schizotypy (Vollema and Hoijtink, 2000) the most importantfeatures of both models will be illustrated. For the one parameter logistic modelthese include: a (discrete) discrimination parameter for each item; a test for itembias; and, estimation of the location of a person on the (latent) trait that is beingmeasured. For the multidimensional Rasch model these include: specification ofthe model; and, model selection. All analyses presented in this paper can be executedusing either OPLM (Verhelst et al., 1995), TESTFACT (Wilson et al.,1984) or ConQuest (Wu et al., 1998). At the end of the paper some features ofmodels and software that have not been discussed will be summarized.     

中国城乡二元工业化反差的理论解析

在我国,以乡镇企业为核心的农村工业化和城市工业化并存,形成了"二元工业化"格局.但是城乡二元工业化有着很大反差.对此反差进行理论解释的目的在于寻找减小这种反差的路径--进行制度创新、城乡工业合理分工、推动农村工业化进程、加快城镇化建设.     

Potential user factors driving adoption of IPTV. What are customers expecting from IPTV?

Internet Protocol Television (IPTV), the convergence services of television and Internet, is being rapidly developed around the world. The advent of digital technologies has changed the convergence market dramatically with the wide diffusion of the convergent services. Using the Technology Acceptance Model as a conceptual framework and method of logistic regression, this research analyzes the demand for IPTV by drawing data from 452 consumers. Individuals' responses to questions about whether they accept IPTV are collected and combined with observations of their socio-economic status and intrinsic/extrinsic factors modified from the Technology Acceptance Model. Results of logistic regression show two variables (intrinsic and extrinsic factors) that seem to explain what influences consumer behavior towards adopting IPTV. Overall, the logistic regression model explains over 50% of the variance in the IPTV adoption. The variances shed light on the multi-open platform environment that IPTV will forge.     

重庆市城乡二元经济结构转换研究

重庆直辖以来经济快速发展,但城乡二元经济结构也非常突出,严重影响全民小康建设进程和经济持续健康发展。以重庆直辖以来的经济数据为基础,从收入水平、消费水平、劳动生产率、城镇化等方面分析了重庆城乡二元性结构特征,结果表明:重庆城乡二元性结构差异显著,且有不断扩大趋势,其主要影响因素包括农业产业化发展缓慢、城镇工业化水平低、城镇工业对农业辐射力弱、城乡市场严重分割、传统体制约束和行政区划调整等。最后提出了加快重庆城乡二元经济结构转换的若干对策建议。     

我国产险公司财务恶化预警——基于Logistic模型

如何准确评估保险公司财务并对财务恶化进行正确的预警．一直是国内外学界、业界及监管机构关注的热点问题之一。本文采用我国产险公司2002～2005年数据，通过Logistic模型找出对产险公司财务状况具有显着影响的各种因素．并利用事前概率与预测概率辨别出财务状况异常的产险公司，在错误成本允许的条件下，寻求最佳的监管资源配置。实证结果表明．在不同的监管标准下，衡量产险公司财务影响因素的显著程度有所差异。模型受检值以事前概率为标准较预测概率为好．且受检值的大小将会影响产险公司财务状况预测的结果。     

重庆市二元经济结构及其转换对策

重庆存在显著的高于全国水平的二元经济结构,并且转换缓慢;其原因在于经济结构发展过程中的二元性、行政体制调整、工业扩张能力弱、农村剩余劳动力转移困难等.二元经济结构的存在,严重影响了重庆经济发展,应加快工业化进程,大力发展农村非农产业,增强对农民的职业教育,加强城乡基础设施建设,以加速二元经济结构的转换.
