基于因子分析的森林康养空间评价 指标体系研究

森林康养空间是开展康养活动、建立森林康养基地 的基本单元。通过4组轮回专家问卷与因子分析法，收集229 份问卷，筛选并构建森林康养空间评价指标体系。结果表明： 1)以康养功能为核心、森林康养空间为目标的评价指标体系 包含3个一级指标、6个二级指标和22个三级指标；2)森林环 境资源与森林空间特征是评价森林康养空间的决定性条件； 3)森林康养空间特征主要体现在环境舒适性、设施便捷性与 空间规模性3方面；4)改善空气负离子浓度、空间可达性、设 施保健功能适宜性、道路联通性、设施服务半径覆盖度和森林 气候舒适度等指标可以显著提升森林康养空间康养效果。本研 究成果能为森林康养空间规划设计及康养效果优化提供一定的 理论支撑。     

我国居民杠杆率现状及影响因素研究

近年来,我国居民部门杠杆率的快速上升引起社会各界关注。本文使用货币信贷和城镇储户调查数据,对我国居民部门杠杆率和偿债能力现状进行了分析,并运用各省住户贷款数据计算各省的居民杠杆率,使用面板数据模型对居民杠杆率上升的原因进行了实证分析。结果表明,房价的快速上涨和住房销售的增长都对居民部门杠杆率的上升有显著正向影响,其中房价上涨的影响程度更大。此外,金融发展水平和老年人抚养比对居民杠杆率有正向影响,少年人抚养比对居民杠杆率有负向影响。     

政府补助企业的主要动机研究——基于我国A股上市公司面板数据的实证检验

上市公司获得的政府补助数额巨大且逐年增长，引起了广泛的质疑，而现有研究对政府补助企业的动机尚无一致的结论。基于理性经济人理论，考虑制度更改和环境变化的影响，以2007—2015年我国上市公司为研究样本，实证检验政府补助企业的主要动机，结果表明：政府补助企业的主要动机在于扩大就业和帮助上市公司“保牌”，最终目的是促进经济的增长；而增加税收和帮助上市公司达到配股要求不是政府补助企业主要考虑的因素，也没有明显证据证明国有企业比民营企业更容易获得政府补助。应完善资本市场退市制度，加强对政府补助的审批和监管，提高政府补助的资源配置效率，并积极引导政府补助发挥更好的社会效益。

Moving freight on public transit: Best practices,challenges, and opportunities

Freight on Transit (FOT) refers to an operational strategy where public transit vehicles and/or infrastructure are used to move freight. Examples include moving goods alongside passengers on buses, attaching cargo trailers to transit vehicles, and operating freight vehicles between trains on subway lines. This paper describes the methods and results of a three-round Delphi study engaging 34 transportation experts to explore challenges and opportunities of FOT and to conceptualize and evaluate potential FOT operations in Toronto. Traditional Delphi methods were used for the exploration of FOT challenges and opportunities, and a modified approach was formulated to integrate experts' opinions and develop new FOT concepts for Toronto. The results support previous claims that technical challenges of FOT may be easier to overcome than institutional barriers. Evaluation of potential FOT operating strategies in Toronto suggests that while the current public transit network does not have capacity to support additional movements, there may be realistic opportunities to include freight service in future projects as a means of offsetting operating costs and reducing the impacts of goods movements.     

How do consumers’ perceptions differ across dimensions of corporate social responsibility and hotel types?

This study develops three hypotheses regarding corporate social responsibility (CSR) in the context of the hotel industry. First, the study examines a ranking of consumers’ perceived importance of the four CSR dimensions proposed by Carroll’s hierarchy of CSR in 1991, expecting the following orders: philanthropic, ethical, legal, and economic dimensions, from most to least important. Second, the study investigates the relationship between consumers’ perceived importance of and their overall support for CSR. Third, the study introduces the type of hotel (for example, economy, mid-scale, and upscale) as a moderator to provide a better explanation of the relationship between consumers’ perceived importance of the CSR dimensions and support for CSR. Contributions to the CSR literature in general, and also specifically relating to the hotel context, and managerial implications are discussed.     

韩国科研器材开放共享法规制度调研

近年来,韩国政府非常重视科教事业,希望通过科技创新实现经济可持续发展,为此,投入大量的科研经费,取得了一些成绩。然而,科研经费投入的增加,科研器材采购管理监管的缺位,造成了韩国大量的科研经费的浪费。为避免浪费,实现科研器材的最大化利用,韩国政府制定了诸多法律法规来规范科研器材的使用和管理,如,《科学技术基本法》、《技术研发促进法》、《基础科学研究振兴法》等相关法律法规。通过对韩国科研器材共享法律法规、科研器材的购置管理和科研器材共享流程等内容的分析研究,期望韩国科研经费使用,特别是在科研器材管理和共享方面好的做法,对我国科研器材管理、完善健全科研器材开放共享机制有所借鉴。     

基于VAR模型的黄金价格影响因素分析

自20世纪70年代初期布雷顿森林体系崩溃之后，美国割断了美元与黄金的固定比价关系，使黄金价格步入了市场化的轨道，黄金价格的大幅波动越演越烈，这使得人们越来越重视探讨影响黄金价格的种种因素。为此，利用VAR模型对黄金价格自身、美国通货膨胀率、国际原油价格等因素与黄金价格总水平的关系进行研究。通过研究得到了各因素影响黄金价格总水平的程度，其中发现黄金价格自身的波动是导致国际黄金价格总水平上升的最主要因素，这为研究黄金价格的变动提供了重要依据。     

Early Experience and Later Outcomes of Education: Schooling Transition Evidence from Indonesia

This paper investigates the effect of early school experience on later educational attainment. Using the Indonesia Family Life Survey (IFLS), we find that students who repeat a grade at primary school are less likely to progress to junior high school. We also find that grade retention is associated with lower rates of transition from junior high school to senior high school. The relationship persists across years and samples. Meanwhile, the age of students when starting school and the hours they spend there have limited effects on whether they continue their schooling. We also observe that the effects of parental education and household income on the transition of students from primary school to junior high school are weakening. Given the long-term impact of grade retention, policymakers should be cautious when recommending it for underachieving children and should look for alternatives.     

The determinants of commercial banking profitability in low-, middle-, and high-income countries

Using a broad bank-level dataset and the GMM estimator technique described by Arellano and Bover (1995), this paper analyses how bank-specific characteristics, macroeconomic variables, and industry-specific factors affect the profitability of 10,165 commercial banks across 118 countries over the period from 1998 to 2012. Grouping the countries according to three income levels, we show that the determinants of bank profitability included in our model can explain existing profitability differences among commercial banks in low-, middle-, and high-income countries. The profitability determinants vary quite widely across the different levels of income in terms of significance, sign and size of the effect. The level of income has thus an important impact on the determinants of bank profitability.
