21世纪低碳经济发展潮流与道路选择

人类社会正在面临有史以来最严重的气候变化困境。发达国家工业化进程中大量排放的二氧化碳等温室气体,导致全球气候变暖。给社会经济可持续发展带来巨大的负面影响。低碳经济是以低能耗、低污染、低排放为基础的经济发展新模式。发展低碳经济、减少二氧化碳排放是应对全球气候变化的有效途径。我国正处于重要的历史发展时期,转变经济发展模式,调整产业结构,优化能源配置,选择低碳经济发展道路,将为我国在全球新一轮经济竞争中赢得发展的先机。     

算法可视化在数据结构教学中的应用

可视化技术是理解复杂现象和大规模数据的一种重要工具,在各个领域都得到了广泛应用。目前,许多研究者已经肯定了算法可视化在数据结构教学方面的作用和地位,并且开始了在算法可视化教学方面的研究。本文从教育的角度探讨如何利用算法可视化达到更好的教学效果以及在教育原则的指导下设计更有效的算法可视化工具。     

企业社会资本与动态能力间关系的实证研究框架——以知识创新为中介变量

从企业社会资本的角度切入,在回顾相关文献及对相关概念界定的基础上深入分析了企业社会资本、知识创新及动态能力之间的相关关系,构建了企业社会资本和动态能力之间关系的实证研究框架:企业社会资本对企业知识创新活动有显著正向影响,知识创新活动对动态能力的形成和发展也有显著的正向影响,知识创新在企业社会资本与动态能力的关系中扮演了中介的角色。     

校园外语广播电台：文化输入的有效途径

校园外语广播电台的开播突破了时空限制,成为学习外语技能和技巧的有效补充。探索外语电台对学习者文化输入的影响。通过电台播音员的个案研究,发现外语电台实践是获得外语文化的有效途径之一。但是外语物质文化易于制度文化、艺术形式文化及文化意识的习得。最后,提出文化选材动态化和文化输入常规化的观点。     

China’s house price: Affected by economic fundamentals or real estate policy?

Many theory and empirical literature conclude that house price can reflect economic fundamentals in the long-term. However, by using China’s panel data of 35 main cities stretching from 1998 to 2007, we find that there is no stable relationship between house price and economic fundamentals. House price has deviated upward from the economic fundamentals since government started macro-control of the real estate market. We consider that the mechanism between the house price and economic fundamentals is distorted by China’s real estate policy, especially its land policy. Meanwhile the policy itself is an important factor in explaining the changes of China’s house price. Then we estimate the dynamic panel data model on house price and the variables which are controlled by real estate policy. The result shows: land supply has negative effects on house price; financial mortgages for real estate have positive effects on house price; and the area of housing sold and the area of vacant housing, which reflects the supply and demand of the housing market, has negative effects on house price. We also find some differences in house price influence factor between eastern and mid-western cities. Finally, we propose policy suggestions according to the empirical results.     

支付制度、医生的行为与药物经济学的应用

制度影响人们的行为选择,引发不同的效率结果。在医疗卫生市场中,不同的支付制度加上一些其他经济因素,使得追求收益最大化的医生具有不同的目标收益函数和行为选择。这些行为选择对社会而言可能具有效率,也可能无效率。通过比较不同支付制度下医生的行为选择及其是否符合效率准则,我们能够发现对药物经济学应用有利的一些制度因素。

樊纲的经济思想——转型理论:改革的政治经济学

樊纲认为改革不是简单的政府决策,而是一个社会内生的、整个社会共同选择的过程。经济体制改革从本质上来说是经济社会中各利益集团的利益相互冲突、其相互关系不断发展、调整的"博弈"过程。中国之所以选择渐进式改革,是由于改革旧体制阻力较大,即无法进行存量改革时,先通过增量改革来发展新体制。随着增量改革的积累,逐步改革整个经济的体制结构,为"存量"的最终改革创造条件。     

中国上市公司现金持有动态调整行为研究

以动态面板数据方法构建的公司现金持有动态调整模型比静态模型更能够捕捉到企业现金持有的动态调整速度和调整形态,利用该模型对我国市场进行实证检验,结果表明,我国上市公司存在最优现金持有水平,但由于调整成本的存在,使得公司在偏离最优水平的情况下只能进行部分调整且调整速度较慢,并由此导致了持续性单方向调整的特殊形态。此外,企业规模、投资机会及财务杠杆等其他一些因素对现金持有动态调整过程也有显著影响。     

An asset-pricing view of external adjustment

Recent literature has argued that conventional measures of external sustainability - the trade balance and current account - are misleading because they omit capital gains on net foreign asset positions. We adjust the definition of the current account to include the capital gains and discuss how this may affect our thinking about external adjustment and sustainability. We do so in the context of a two-country macro-finance model of Pavlova and Rigobon (2008a) that allows exploration of the interconnections between equilibrium portfolios and external accounts' dynamics. We calibrate the model and find that it generates several testable implications, some of which have already been validated empirically. First, we establish dynamic properties of the capital-gains adjusted current account and show that they are fundamentally different from those of the conventional current account. Second, we find that capital gains have a stabilizing effect on the trade balance and the current account. Finally, we demonstrate that in response to a shock, the conventional and the capital-gains adjusted current accounts may move in opposite directions.
