Schumpeter,Schumacher and the Greening of Technology

We propose a semantic patent claim analysis that can examine patents for possible infringements and identify which needs to be manually perused. So far, numerous approaches have been devised to systemise this burden, but have not been useful in practice because of a lack of consideration of semi-structure of patent claim data and claim element-based procedure of adjudicating patent infringement. At the heart of our method is a hierarchical keyword vector for representing the dependency relationships among claim elements (as well as unstructured textual information) and a tree matching algorithm for comparing claim elements of patents. A case study of the patents about DNA chip technology shows our method has considerable advantages in terms of accuracy and significance. We believe the suggested method could be employed in various research areas and serve as a starting point for developing more general models.     

Investor Sentiment and Stock Market Volatility: Evidence from India

In this article, the authors probe the role of irrational investor sentiment in the determination of Indian stock market volatility. The authors developed a new irrational aggregate sentiment index (IASI) to examine the issue. The conditional volatility is extracted from the nonlinear univariate models for the market indices and the IASI. The vector autoregression (VAR) is carried out to analyze the relationship between the volatility of irrational aggregate sentiment index and stock market volatility. The authors find a unidirectional causality from sentiment to stock market volatility, and their findings highlight the significance of sentiment in explaining the stock market volatility in India.     

一种三维调制信号快速解调新方法

根据三维调制信号的特性,提出了一种新的三维调制信号的快速解调方法。该方法 基于MUSIC算法,首先利用单次快拍来建立阵列数据的协方差矩阵,然后根据调制信号的先 验信息对所得信号空间谱进行判决,来估计其极化辅角与极化相位角等信息,从而恢复出基 带信号。分析与仿真结果表明,所提方法不仅可以避免谱搜索,大大降低MUSIC方法的运 算量,而且适用于瞬时信号和快速运动信号的解调。

科学有效地对公司的财务状况进行评价,不仅对公司财务危机预防具有重要作用,对促进资本市场更好更快发展也至关重要。基于人工神经网络和支持向量机的思想,以我国2009年276家中小上市公司的财务数据作为输入特征向量,建立中小上市公司财务评价模型,使用该模型分析的结果与样本企业实际情况相符,表明该模型有效性较高。     

Trade in Services: The Elasticity Approach for The Case of Turkey

This study includes the analysis of global trade in the services and service sector in Turkey, and estimates the elasticity of trade in services to real exchange rates and income. There is an increasing role of the service sector in the Turkish economy; however, a decreasing trend of trade in services is taking place. The commitments of the General Agreement on Trade in Services (GATS) were found to be ineffective, at least in the case of Turkey. The empirical findings suggest that the real exchange rate is not a significant determinant for the trade in services. We found an inelastic real exchange rate and income elasticities in trade demand functions. However, the value of income elasticity significantly exceeds the value of real exchange rate elasticity.     

Threshold Cointegration in the Greek Milk Market

This article investigates the nonlinear adjustment between consumer and producer prices in the Greek milk sector using a threshold error correction autoregressive model. The results reject the null hypothesis of linear cointegration in favor of a 2-regime threshold cointegration model. A cointegrating relationship is expected only when equilibrium consumer price is decreased more than 24.12% or the equilibrium relative markup is squeezed more than 62.74%. In this case consumer prices have to increase faster than producer prices to restore the long-run equilibrium between consumer-producer milk prices.     

人力资源市场和谐发展的宏观视角研究——基于山东劳动力市场的实证分析

合理解决劳动力就业问题已成为经济能否持续有效发展、创建和谐社会的关键因素之一。文章以山东为例,利用协整检验对长期模型中可能影响劳动力就业的GDP增长、外商直接投资、三大产业结构特征以及教育和技术研发投入金额等因素进行实证分析;利用向量误差修正模型和广义脉冲响应函数研究各影响因素对人力资本市场需求的短期冲击;同时利用Granger因果检验对各主要影响因素和就业情况的内在因果关系进行检测;最后对我国劳动力就业形势进行预测并提出相关政策建议。     

陕西省财政支出结构的实证分析

财政支出对经济增长的影响不仅表现在总量上,而且表现在财政支出的结构关系上。文章着重分析了1978-2006年陕西省财政支出与经济增长的关系,发现经济增长促进了政府财政支出规模的扩张,并利用VAR模型和IRF检验了财政支出结构对经济增长的影响。     

城乡收入差距与经济增长关系的实证研究——基于中国1978-2007年数据的协整检验与脉冲响应分析

对中国1978—2007年数据的实证研究结果表明：城乡收入差距与经济增长之间存在着长期稳定的双向因果关系：城乡收入差距只在短期内对经济增长产生影响;而经济增长并不会自动导致城乡收入差距的缩小,相反,经济增长在中长期内还会进一步加大城乡收入差距。     

大丰港货物吞吐量的时间序列法预测研究

根据大丰港的历史数据,采用时间序列的回归分析方法对大丰港货物吞吐量进行预测研究。在回归分析法中,通过比较,选择指数模型、高次多项式模型以及支持向量机方法分别对大丰港的货物吞吐量进行模拟预测。对指数模型、多项式模型、支持向量机三种方法的预测结果进行比较,并结合大丰港的实际情况,最终选择使用支持向量机法给出大丰港2012—2016年的货物吞吐量预测值。
