Does international capital flow lead to a housing boom? A time-varying evidence from China

This paper examines the causal relationship between the housing prices (HP) and the international capital flows (ICF) in China. With structural changes existing, we find that long-run relationship using full-sample data is unstable, suggesting that traditional Granger causality test is not reliable. However, we further find an unstable short-run relationship between ICF and HP when assessing the stability of the parameters and there are bidirectional causal relationships between ICF and HP for several sub-periods. Additionally, our findings indicate both positive and negative bidirectional causal relations between the series. Based on the arbitrage of ICF, the results suggest that the rise of Chinese HP is the underlying force for the inflows of international capital. Meanwhile, a surge in capital inflows may be accompanied by a rise in the price of housing. This confirms the theoretical analysis that there is an interconnected transmission mechanism between the ICF and the HP, which is diverse and depends both on the flow of ICF and on other factors.     

工业4.0驱动:基于制造企业智能化的股权结构实证研究

从投资者结构角度研究企业层面工业智能化的驱动力,用委托代理理论分析股权结构对企业智能化投资的影响。以中国制造业上市公司为研究样本,实证检验股权结构对企业智能化投资的关系。研究结果表明,从股权集中角度看,一定的股权制衡很有必要,一股独大不利于企业智能化投资;从企业性质看,公有企业更愿意进行智能化投资,个人私有的第一大股东不太愿意进行智能化投资;从激励角度看,高管薪酬与智能化投资之间的关系不明确,说明目前的薪酬激励制度不够合理;从地区文化角度看,越是发达的地区企业越容易接受智能化投资。     

Energy benchmarking in support of low carbon hotels: Developments,challenges, and approaches in China

Achieving effective and objective energy benchmarking for hotels is integral in fostering the sustainable development of the lodging sector. In this work, we reveal the major and minor streams of hotel energy benchmarking and ascertain that the most popular approach in benchmarking is normalized energy use intensity (EUI) based on floor level. Previous efforts to establish EUI indicators using subsystem average, data envelopment analysis (DEA), and regression technique are also studied. We propose that hotel energy benchmarking based on floor area is useful from the top-down management perspective. However, on a practical perspective, energy benchmarking based on facilities should be the first priority for hotel management or owners. Compared with the general energy benchmarking in the building sector, we find that the hotel sector lags behind in the adoption of computer modeling for benchmarking.     

汇率预测的神经网络方法及其比较

浮动汇率兴起以来,大量的参数方法和非参数方法被用于汇率预测,神经网络是其中的一种.神经网络方法在汇率预测中的应用有三种不同的方法:同质神经网络模型、异质神经网络模型和神经网络组合模型.本文讨论了三种神经网络预测模型的特点以及局限性,并通过时这三种方法的比较得出结论:神经网络组合模型充分考虑了汇率的线性特征和非线性特征,比同质神经网络和异质神经网络预测模型更系统、更全面,能更好地进行汇率预测.     

New evidence of regional income divergence in post-reform Russia

This article investigates regional income convergence in Russia during 2000–2008. We test the hypothesis in which income divergence across regions of the country should give place to income convergence as the country moves toward free market economy with strong market institutions. The study contributes to the existing literature by using the exponential smooth autoregressive Augmented Dickey–Fuller (ADF) unit root test in a panel setup, a novel econometric technique, which encompasses cross sectional dependence. Results show strong evidence of on-going regional income divergence in post-reform period.     

基于分类最优原理的小企业信用风险评价

基于分类最优原理进行小企业信用风险评价,即以违约样本和非违约样本的重心距离最大为目标函数,以指标的三角模糊熵及变异系数组成的指标权重区间为约束条件,确定指标的组合权重,评价小企业信用风险状况。应用实例结果表明:利用该方法评价小企业的信用风险,能够更好地区分违约客户与非违约客户,使模型的判别精度有所提高。     

多维企业家社会资本、企业吸收能力与企业绩效研究

基于社会资本理论,将企业家社会资本划分为市场、制度及金融3个维度,利用139家中国创业板上市公司数据,对企业家社会资本、企业吸收能力、企业财务绩效及创新绩效的内在关系进行实证分析。实证结果表明,企业家市场社会资本对企业财务绩效和创新绩效具有显著的正向影响,企业吸收能力与企业财务绩效及创新绩效显著正相关。企业吸收能力正向调节企业家市场社会资本与企业财务绩效和创新绩效的关系,也正向调节企业家制度社会资本与企业创新绩效的关系。     

人民币汇率波动对国际企业价值影响实证研究

双对数计量经济模型可以较为准确地描述人民币汇率对国际企业价值的影响.实证分析表明,人民币汇率对企业中短期产生的影响较大,且影响强度随着国际企业外贸收入占主营业务收入比例的增长而增大.通过对行业指数(包括非金融行业指数和金融行业指数)的中期历史数据的分析,发现不同行业受到外汇风险的影响各有不同.作为研究结果的应用,根据实证结论有针对性地提出了外汇风险管理建议.     

武当山风景名胜区五龙宫景区风景 特质识别研究

风景特质评价(Landscape Character Assessment)作为一种管理风景变化的新工具,近年来受到了广泛关注。目前风景特质评价的研究对象多集中在国土尺度或自然乡野地,对于风景名胜区特质的识别研究尚属空白。介绍了风景特质评价的基本流程,尝试对武当山风景名胜区中的五龙宫景区进行风景特质识别,绘制了武当山风景名胜区的风景特质图,总结了英国风景特质评价作业体系的优缺点及研究局限,提出了今后的研究展望和建议
