生产效率与转型升级——基于房地产业的分析

目的/意义宏观经济形势的变化影响着微观企业行为,新的经济形势要求房地产企业必须转变经营观念,改变经营模式,因此各房地产企业开始谋求转型。各企业转型方向各有千秋,转型效果也不尽相同。因此,对企业转型方向的分析至关重要。方法/过程以房地产行业为例,利用DEA-Malmquist模型与DBSCAN算法,综合考虑各项财务指标,计算92家房地产上市企业2013—2017年各年全要素生产率和历年平均值,并且将92家房地产上市企业财务指标与TFP值进行聚类分析。结果/结论结果显示:房地产企业的经营方向逐渐向着两个趋势——高资产负债率+低技术进步率和低资产负债率+高技术进步率演进;我国房地产行业大部分企业处于低要素利用率、低技术进步率的阶段。     

China-ASEAN Free Trade Area：Ready？Go!——No Easy Gain

At the beginning of 2010, the overall start of China-ASEAN Free Trade Area （CAFTA） came as a milestone in the annals of China-ASEAN relations, and it may well serve as a model for regional cooperation not only in Asia, but also other parts of the world.     

Comparative Research with Net and Gross Income Data: An Evaluation of Two Netting Down Procedures for the LIS Database

Researchers seeking to perform country‐comparative and trend analyses using income data have to account for the fact that income surveys differ in whether income is measured gross or net of taxes and contributions. We discuss, develop, and evaluate two ‘netting down procedures’ for data in the LIS Database. Evaluations of these netting down procedures indicate that comparisons across gross and net datasets can be greatly improved when netting down procedures are applied. In several cases, however, substantial amounts of bias remain.     

Tony Atkinson and his Legacy

Tony Atkinson is universally celebrated for his outstanding contributions to the measurement and analysis of inequality, but he never saw the study of inequality as a separate branch of economics. He was an economist in the classical sense, rejecting any sub‐field labelling of his interests and expertise, and he made contributions right across economics. His death on 1 January 2017 deprived the world of both an intellectual giant and a deeply committed public servant in the broadest sense of the term. This collective tribute highlights the range, depth and importance of Tony's enormous legacy, the product of almost fifty years’ work.     

No Easy Gain

Financial crisis-the drive to integration of regional economies Two salient features are illustrated in today's global economy pattern,which is,economic globalization and the integration of regional economies.The integration of regional economies stimulates the globalization,while on the other hand integrating countries that are geographically close aims to fight against the negative impact from globalization,including the financial crisis.     

水性轮转凹印油墨在PET和BOPP基材上印刷的对比研究

采用凹印机（最大速度500m／min）在PET（聚对苯二甲酸乙二醇酯）和BOPP（双向拉伸聚丙烯）承印物上进行印刷试验,以研究高速凹版印刷下油墨的转移情况和印刷适性。将水性油墨用酒精稀释后,在特定的印刷速度、印刷压力和网穴尺寸等多种印刷设备条件下对柔性承印物进行印刷。采用光学显微镜、UV可见光谱仪和原子力显微镜（AFM）测量印刷图像和油墨转移率。通过对界面张力、黏度以及油墨与承印物之间润湿角的测量与评价,定量分析它们对印刷特性的影响。实验结果表明,影响印刷特性的最重要的因素是油墨黏度、表面张力和界面张力。稀释后的油墨在PET和BOPP薄膜上的铺展系数都小于零,也就是说油墨难以在二者上顺利铺展,因此,扩散可能是由于剪切力导致油墨流动。显微镜或光谱仪测量表明,在各种试验印刷设备条件下,印刷速度不会对PET薄膜上印刷图像的均匀性和色度产生很大影响,而BOPP薄膜上的图像质量则在很大程度上依赖于转速。两者存在差异的主要原因在于BOPP薄膜多孔表面的毛细管堵塞导致油墨的铺展能力降低。此外,网穴尺寸（网点百分比）增大导致色度增大,其原因在于油墨和承印物间的接触面积变大。尤其对于BOPP薄膜来说,其印刷图像的色度会随着网点百分比的增大而线性增大。应该指出,在相同的稀释条件和设备条件下,较之PET薄膜来说,BOPP薄膜上的印刷图像的色度与墨层厚度远远高于PET薄膜。BOPP与PET薄膜在油墨转移率上的较大差异也许可以在一定程度上解释两者在界面张力上的差异,以及BOPP承印物上的吸收现象。     

The role of transformational leadership,emotional intelligence,and group cohesiveness on leadership emergence

The concept of emotional intelligence and its connections with other important psychological constructs have been the focus of a wide range of current research (see Mestre & Fernández‐Berrocal, 2007, and Salovey, Woolery, & Mayer, 2001, for reviews). Yet the relationship between emotional intelligence and transformational leadership, a leadership style that is highly correlated with efficiency and satisfaction of the leaders' followers, has scarcely been analyzed. We hypothesize that individuals who score high in emotional intelligence emerge as leaders more easily than low‐emotional‐intelligence individuals due to the fact that they are more transformational in their leadership style. We further suggest that this is especially the case in highly cohesive groups. In this study, we test these ideas and find empirical support for our hypotheses.     

跨国公司研发机构中国区位选择因素的实证分析

相对于跨国公司在中国直接投资的研究,学者关于跨国公司对中国研发投资的研究并不多。本文是以加入WTO以后市场规模日益增大的中国市场为研究对象。通过建立多元线性回归模型对影响跨国公司研发投资区位选择三大基础因素进行实证分析,以期验证影响和决定跨国公司研发机构在中国区位分布的各个基础经济变量的有效性。     

农村金融服务的困境与规范创新的路径选择

文章分析了我国农村金融服务中存在的问题,我国农村金融服务的发展水平不高,金融效率低,与农村经济发展相比相对滞后,农村金融改革不是规范与创新的秩序之争,而应是规范与创新并举。
