Green decisions: demographics and consumer understanding of environmental labels

This research examined the demographic profiles of Australian green consumers in relation to their satisfaction of environmental labelling. It examined consumers’ understanding of labelling and empirically investigated the association of demographic profile of consumers with their attitudes towards such labels. The results indicated that some of the demographic variables were significant, which is largely consistent with earlier findings by other researchers in this area. Label dissatisfaction was higher in the older and middle age respondents. However, some respondents disagreed that labels were accurate while commenting that labels were easy to understand. The key issue arising from the findings is that in order to provide perception of accuracy in labels, it is an option to use Type I or Type III labelling on products. These labels are, arguably, more credible because they are endorsed by third party labelling experts. This would come at a cost and for green products that use third party labelling, they will also have to bear in mind to keep the prices competitive.     

我国石油对外贸易流量分析与对策研究

石油是关系国家经济安全的重要战略物资,本文通过对我国石油进出口贸易一些流量指标的分析,发现:(1)石油净进口量过大,进口依存度偏高,并有逐年递增的趋势;(2)原油进口的地区集中度偏高,不利于石油资源供应稳定;(3)国际油价持续高企,对国内经济稳定造成威胁。并据此提出了相关政策建议。     

高铁开通与城市创新研究综述

高铁网络的建设大大提高了中国铁路运输的效率,缩短了不同城市之间的时空距离,使居民在不同城市工作和消费成为可能。同时高铁服务通过加速人口和要素在区域间的流动,对城市之间的空间联系和城市社会经济的发展产生了重要的影响。高铁在影响经济格局的同时也深刻影响了区域的创新格局,现通过梳理相关文献,整理归纳了高铁开通对城市创新的影响及其作用机制,并对现有的实证研究方法进行总结。在此基础上提出目前存在的问题,为后续的研究指明方向。     

大股东控制、市场化程度与公司现金持有水平

运用2003～2008年我国所有非金融类A股上市公司的样本数据,从大股东控制视角出发,重点关注第一大股东持股比例、实际控制人性质和公司所在地区市场化程度对于公司现金持有水平的共同作用。结果表明,第一大股东持股比例与公司现金持有量水平正相关,实际控制人为国有的比非国有的上市公司的现金持有量高;公司外部治理环境的改善,有助于减轻由第一大股东持股比例以及实际控制人性质对公司现金持有量造成的负面影响。     

美国第二轮量化宽松货币政策的影响及中国对策

美联储第二轮量化宽松货币政策预计对美国经济的刺激作用有限,并会对其他国家特别是新兴市场带来较严重的负面溢出效应。其中,美元泛滥可能引发较为严重的通货膨胀,并刺激贸易保护主义抬头。中国需要采取＂堵疏结合、攻防有序＂的手段,严格监控风险度高的短期流动资金,将长期资金流入有效疏导到金融短板加以利用,力保经济平稳较快发展。同时,应加强与国际社会的协作,对美国量化宽松政策形成一定的制约。     

信息流协同因素实证分析与模型构建

本文首先对物流园区信息流协同研究的文献进行了梳理和综述,介绍了物流园区信息流协同的概念,选择物流园区的5个维度的信息流协同影响因素进行问卷调查,取得了第一手数据。然后运用SPSS软件和回归统计分析方法,对数据进行信度分析、效度分析和因子分析。分析表明选择的影响因素具有比较好的结构效度,是可信和比较完备的。在此基础上构建了反映物流园区信息流协同效应的信息流I模型。最后对"信息平台"建设提出了建议。     

管理层持股、自由现金流与企业过度投资行为研究

在现代企业制度下,通过管理层持股将股东与管理层之间的堑壕效应转化为利益协同效应,能有效减少管理层的过度投资行为。通过实证研究发现,管理层持股与企业过度投资—自由现金流存在二次曲线关系,过度投资对自由现金流的敏感性与管理层持股呈正U型关系。当管理层持股达到一定比例时,企业过度投资对自由现金流敏感度最低,对企业抑制过度投资的作用最大。     

Are analysts' cash flow forecasts useful?

This study provides evidence that the cost of equity capital decreases with the number of analysts who issue both cash flow and earnings forecasts (cash analysts). The evidence also shows that cash analysts reduce information asymmetry and predict long‐term earnings more accurately than analysts who issue only earnings forecasts. Taken together, these findings suggest that cash analysts provide market participants with high‐quality information and, as a result, firms benefit from cash analyst coverage in the form of a reduced cost of equity capital.     

Assessing the Impacts of Capital Inflows on Domestic Economy across the Sub-Saharan Africa Countries

Using GMM models, this paper analyzes the impacts of capital inflows on domestic investment in 44 Sub-Saharan Africa (SSA) countries from 2003–2012. It is found that foreign direct investment across the SSA remains to be the largest percentage share, accounting for 35% of the total capital inflows. FDI inflows have significant positive impacts on domestic investment across the SSA in both short term and long term. Other key macroeconomic factors such as age dependency ratio, domestic economic growth, terms of trade, real effective exchange rate and trade openness also play vital roles in determining domestic investment.     

城镇化与工业化互动发展的协调性与驱动力研究——来自四川省21个市州的经验证据

城镇化与工业化互动协调发展是城乡经济发展的一个主要问题。在构建新型城镇化和新型工业化评价指标体系的基础上,采用四川省21个市州2007—2012年相关数据,运用“协调度—协调发展度模型”和灰色系统模型 GM（1,N）,对城镇化与工业化互动发展的协调性进行评价,并揭示其内在驱动力,结果表明：四川省城镇化与工业化互动发展的协调度与协调发展度处于不断提高的过程中,21个市州工业化发展对城镇化与工业化互动协调发展均起着促进作用,但经济发展水平极高和极低市州的城镇化发展对城镇化与工业化互动协调发展具有制约作用。因此,应以工业化带动城镇化发展,制定差别化的城镇化与工业化互动发展政策,全面深化制度改革,形成城镇化与工业化互动协调发展的良性机制。
