新型工业化、城市化联动与经济生态化发展研究——基于湖南的相关实证

在综合相关研究指标体系的基础上,构建能反映地域新型工业化水平、城市化水平及生态化水平三个方面的评价指标体系。主要采用VAR(向量自回归)、VEC模型等来研究新型工业化、城市化联动与经济生态化发展之间的动态相关程度,定量分析三者之间的短期、长期影响。研究结论表明:从长期来看,三者之间并不存在显著的双向格兰杰因果关系,但存在显著的单向格兰杰因果关系;从短期冲击效应的角度来看,三者均受到自身的影响冲击最大,但存在显著的协整关系,而且随着年限的增加,三者之间的冲击影响程度会发生较大的转化。     

Risk Interpretation of the CAPM's Beta: Evidence from a New Research Method

This study tests the validity of using the CAPM beta as a risk control in cross‐sectional accounting and finance research. We recognize that high‐risk stocks should experience either very good or very bad returns more frequently compared to low‐risk stocks, that is, high‐risk stocks should cluster in the tails of the cross‐sectional return distribution. Building on this intuition, we test the risk interpretation of the CAPM's beta by examining if high‐beta stocks are more likely than low‐beta stocks to experience either very high or very low returns. Our empirical results indicate that beta is a strong predictor of large positive and large negative returns, which confirms that beta is a valid empirical risk measure and that researchers should use beta as a risk control in empirical tests. Further, we show that because the relation between beta and returns is U‐shaped, that is, high betas predict both very high and very low returns, linear cross‐sectional regression models, for example, Fama–MacBeth regressions, will fail on average to reject the null hypothesis that beta does not capture risk. This result explains why previous studies find no significant cross‐sectional relation between beta and returns.     

New accounts: Towards a reframing of social accounting

This paper is a speculative and exploratory essay on the emerging field of social accounting. In essence, the paper explores whether the fact that most social accounting has, traditionally at any rate, being promulgated by accountants might be a partial explanation for its self-disciplining limitations and, arguably, its weak inroads into discourse and practice. Through the lens of Erik Olin Wright's work, the paper reconsiders the potential of the social accounting project(s) and argues for the importance of accounts as a means of interstitial transformation as a complement to the traditional privileging of accounts directed towards symbiotic transformations.     

新材料产业技术创新联盟模式研究

新材料产业发展的关键在于产业技术创新。考量新材料产业发展状况和新材料产业技术创新联盟成员构成情况,按照技术创新难易程度以及产业技术创新联盟中不同的主导力量,构建为政府推动型、学研驱动型和市场导向型三类新材料产业技术创新联盟模式模式。政府推动型模式适用于市场前景不明朗、创新风险大、政府直接或间接介入的重大技术创新领域;学研驱动型模式适用于科技含量较高的重点技术创新领域;市场导向型模式适用于企业有技术创新需求但需要合作研发才能实现的一般性技术创新领域。     

基于两阶段DEA模型的上市公司债权融资效率研究——以战略性新兴产业新能源汽车为例

运用两阶段关联网络DEA模型,对我国新能源汽车产业上市公司的债权融资效率及各子阶段对应效率进行了测算。研究结果表明:新能源汽车产业上市公司债权融资效率水平偏低,而债权筹资效率相对低下是其主要原因;随着时间推移,大部分新能源汽车产业上市公司两阶段效率逐渐趋向双重高效。     

Destination image differences between visitors and non‐visitors: a case of New York city

This note discusses the influences of previous visits on tourists' destination images. The cognitive and affective images of New York City (NYC) appear to change in certain directions after visiting. The results also found that city images have a significant influence on tourists' visit intention. However, previous visits to NYC did not play any moderating effect between destination images and visiting intention. Copyright © 2010 John Wiley & Sons, Ltd.     

国际金融监管发展的新趋势及对我国的启示

Assembly FG: An Educational Case on MRP II Integrated within ERP

This case teaches students how discrete (job order) manufacturing companies use Manufacturing Resource Planning (MRP II) within Enterprise Resource Planning (ERP) systems to plan purchase orders for direct materials and shop orders for work‐in‐process and finished goods. Students simulate MRP II integrated within ERP, using Microsoft Excel to learn MRP II's bill‐of‐materials (BOM) Explosion that plans order quantities and MRP II's scheduling logic that uses lead‐times to determine start dates for planned orders. Students explain why MRP II is most practical and effective when executed within ERP and how MRP II can reduce excess inventories, prevent inventory shortages, and help companies deliver quality products to customers on schedule. Also, students explain why BOM, inventory, and lead‐time inaccuracies can adversely affect the accuracy of MRP II‐planned replenishments and identify controls that reduce the risks of these inaccuracies.     

A simple template for pitching research

In this article, I propose a simple new research tool – a template designed for pitching research. The two‐page pitching template begins with four ‘preliminaries’: working title, research question, key papers and motivation. Following this is the core of the template based on a ‘3‐2‐1 countdown’, namely THREE elements – idea, data and tools; TWO questions – What's new? and So what?; and ONE bottom line – contribution. The template ends with ‘other’ considerations. Finance and accounting examples are given to illustrate application of the template.     

Keynesian Inefficiency and Optimal Policy: A New Monetarist Approach

A simple model of monetary/labor search is constructed to study Keynesian indeterminacy and optimal policy. In the model, economic agents have trouble splitting the surplus from exchange appropriately, and we consider monetary and fiscal policies that correct this Keynesian inefficiency. A Taylor rule neither implies determinacy, nor does it support an efficient outcome. An optimal policy yields an efficient and determinate allocation of resources, but equilibrium policy actions, wages, and prices are indeterminate at the optimum.
