中国货币需求函数的协整分析

本文从目前中国货币需求现状出发,修正了1978年以来中国的货币需求函数,并运用协整分析对中国相关变量的年度数据(1978—2004年)进行实证分析,得出以下结论:在长期内,实际M1余额、实际GDP、一年期定期存款利率和货币化进程指数间存在协整关系;实际M2余额、实际GDP、商品零售物价指数和货币化指数间存在协整关系。在短期货币函数中,对货币需求的主要影响因素包括实际GDP和货币化进程,实际M1向均衡水平调整的速度要大于实际M2的调整速度,另外,短期货币需求函数不稳定。     

加强我国城市供水价格机制改革的探讨

随着国民经济的持续快速发展和城市化进程的加快,我国已经有相当部分城市出现了水资源短缺的 状况,城市缺水范围不断扩大,缺水程度日趋严重,水质日益恶化,许多沿江、沿河城市不断受到洪水威 胁,水短缺、水污染、水安全等已经成为制约国民和社会发展的重要因素,对２１世纪我国的环境与发展造成 了巨大的潜在压力。特别是水资源对于将来的地区和平、全球粮食安全、城市经济的增长、工业的选址、能 源化工基地的建设、城市规划的实施,以及西部大开发的推进,都产生着越来越深刻的影响。可是,由于我 国目前的城市供水价格机制不尽健全,在一定程度上不利于加强水资源使用的宏观调控,降低了水资源的利 用效率,成为国民经济发展的制约和瓶颈。因此,探讨科学的城市供水价格机制,具有重要现实意义。     

盈余管理方向与企业投资效率

以2008—2010年沪深A股上市公司为研究样本,从盈余管理的不同方向考察盈余管理程度对企业投资效率的影响,研究发现：适度的正向盈余管理有助于缓和企业投资不足,但过度的正向盈余管理反而会恶化企业投资不足;负向盈余管理往往会伴随产生投资不足的问题。适度的正向盈余管理能够提振投资者信心,从而缓解企业的融资约束。监管部门应该能够容忍企业进行适度的盈余管理,而不是一味地强调所谓“真实的会计信息”。     

货币供应、通货膨胀与经济增长的互动关系研究——基于时变参数VAR模型的实证检验

文章以我国1996年1月至2012年12月的月度数据为基础,首次建立了货币增长率、通货膨胀率和经济增长率的带随机波动的时变参数VAR模型（TVP-VAR）,以此来考察货币供应、通货膨胀和经济增长之间的互动关系。研究结果表明：货币增长短期内促进经济增长,但长期内对经济增长没有驱动效应;货币增长短期内对通货膨胀的作用不确定,而在中长期时间内货币扩张会引发通货膨胀。经济的增长并没有推动货币增长,经济增长在短期内导致通货膨胀,但在长期内经济增长对通货膨胀的影响基本不存在;通货膨胀对经济增长和货币增长的作用依状态而变化。     

基于调控方向差异的货币政策区域效应研究

实证研究结论表明:我国货币政策的作用真实表现为正向或负向货币供给冲击;正向或负向货币供给冲击对我国东部地区、东北地区、西部地区和中部地区的影响是不一样的,即存在紧缩性与扩张性货币政策区域效应;我国货币供给冲击是东部地区、东北地区和西部地区经济增长率的Granger原因,不是中部地区经济增长率的Granger原因;我国紧缩性与扩张性货币政策区域效应主要是与不同地区金融机构分布和货币政策传导渠道的不同有关。     

对首届"河南文化遗产日"的调查和思考

2005年11月26日、27日河南省在我国率先设立了"文化遗产日",这是对我国文化遗产保护的一种新尝试.那么,文化遗产日的设立能否得到认可,它有什么样的效应?又存在什么样的问题?弄清这些对我国文化遗产的保护和发展有着重要的意义.通过调查研究发现,游客、媒体和网友对文化遗产日的设立大都持肯定的态度,认为文化遗产日具有众多的积极效应,但游客对文化遗产日的感受不是很好,文化遗产日暴露的问题,将影响着人们进一步参加文化遗产日的可能性.最后,文章对首届河南文化遗产日进行了评价,对相关问题进行了初步的探讨.

Predicting Internet banking adoption in India: a perceived risk perspective

The emergence of Internet banking has transformed the banking systems across the globe. As a channel to market, Internet banking allows geographical constraints to be overcome by offering various products and services at lower customer costs. An understanding of the factors influencing customer adoption of Internet banking is both relevant and timely. This study integrates technology acceptance model and perceived risk theory in understanding Internet banking acceptance among Indian bank account holders. Specifically, this study categorizes perceived risk as external risk and internal risk, and examines its influence on customer beliefs and adoption of Internet banking. Using two-step predictive analytics of structural equation modeling and artificial neural network analysis, the 270 responses reveal that both external risk and internal risk inhibit customer acceptance of Internet banking. More importantly, neural network analysis reveals that perceived ease of use and external risk are two important factors determining how well Internet banking is accepted by customers. The implications of the study findings and future research directions are presented.     

Does Social Media Matter? Investigating the Effect of Social Media Features on Consumer Attitudes

The purpose of this study is to explore the impact of social media's features (i.e., entertainment, usefulness, informativeness and irritation) toward consumers’ attitude toward the brand. Subsequently, this study explores the impact of this attitude toward consumers’ brand loyalty, brand awareness and purchase intention. Data for this study was collected through a large public university in Australia. Paper surveys were distributed to students, their friends and members of their immediate families (N = 724). The findings show that entertainment feature has the strongest impact on consumers’ attitude toward the brand's social media use, followed by informativeness, usefulness and finally, irritation. Consumers’ attitude toward a brand's social media strongly influences consumer loyalty, awareness and purchase intention. The findings of this research provide some insights into the impact of different features of social media which will be useful for practitioners and academics interested in social media.     

Educating limited resource older adults for better choices to lower risk of food insecurity

United States (U.S.) national and North Carolina state data on older adult food insecurity in combination with associated poor nutrition‐related health outcomes point to a critical need for interventions to improve their food security. Nearly 8% of North Carolinians aged 60 and older and 11% of those aged 50–59 are food insecure, placing North Carolina in the top ten states in the U.S. for food insecurity for both age groups. Therefore, the Better Choices intervention was designed to educate limited‐income older adults in ways to manage their meager resources to purchase more and healthier foods. The purpose of this study was to determine the effectiveness of the Better Choices intervention in improving the knowledge, attitude, and behavior of participants concerning their food money resource management. Older adults (n = 453) with ages ranging from 59 to over 90 years participated in 8 weeks of educational programming delivered by educators in 15 participating North Carolina counties. In a cross‐over program design participating counties were randomly assigned to two groups, to create a control for the food money resource management treatment. A three‐points‐in‐time survey supported longitudinal measurement. Independent samples t‐tests showed no significant differences between groups at baseline. Paired sample t‐test results show the intervention was effective with statistically significant improvement of participants' knowledge regarding preparing a healthy meal on a budget, beans as a low‐cost alternative to meat, and the use of unit pricing to compare products to identify the best value. Participant‐developed action plans reflected planned behavior change. Study results show this group of older adults were capable of and willing to adopt new behaviors for a healthier lifestyle. While not a representative sample, the broad applicability of adult learning and planned behavior theories underpinning the program lead us to conclude that the methods and theories applied in this intervention should be of use to educators and practitioners serving limited‐resource older adult populations.
