基于FIGARCH模型的中国房地产指数的实证分析

在T分布和正态分布假设下采用GARCH模型和FIGARCH模型对上证地产股指数日收益率序列进行建模分析,结果表明,上证地产股指数日收益率序列的波动具有显著的长记忆性,表明外部冲击对波动有着长期的影响。因此,采用FIGARCH模型建模的效果优于采用GARCH模型建模的效果,并且在T分布假设下拟合模型,其效果优于在正态分布假设下拟合的模型。     

Product manager in perspective

While many articles have been written on a diversity of topics relating to the product management system, practically nothing has been reported on the backgrounds of product (or brand) managers. Therefore, the purpose of this article is to provide some current information and insight into this area. Specifically investigated are the backgrounds of current product managers, their career paths, their current profiles, and finally, where they go after leaving product management. Also studied were the opinions of the current product managers on what background is necessary for success in the field, as well as their opinions on some contemporary issues and future prospects for the product management system.     

人口分布、隔离指数及其地理视角——以上海市外来人口分布为例

人口分布具有强烈的地理性,但是相应的空间变动却常常被主流学派所忽视。将空间性思维加入到人口分布的研究当中,关注于不同群体人口分布的局部空间变动,并使用相应的空间性指标进行分析。对这些空间性指标进行了理论探讨,并将其应用于上海市外来人口分布的实证研究中。上海市外来人口主要聚集在距离中心城区10-20公里范围内的近郊区,呈现出有规律性的环状分布。使用空间性的分析指标能够探测出城市社会空间分布的结构,并分析其动力演化机制,为构建和谐的城市社会提供研究依据。     

完善我国环境保护税收制度的思考

当前,我国资源破坏和环境污染问题相当严峻,要实现中国跨世纪环保政策目标和可持续发展战略,必须依靠税收这种有效的经济手段。但是,我国现行的税费政策总体作用有限,因而必须进一步完善我国环境保护税收制度,一是改革和完善现行资源税;二是及时开征环境保护税;三是在其它一般性税收中采取各种税收调节措施,体现环保目标。     

政府科技支出如何作用于区域创新能力？——区域创新中政府与企业、市场关系的思考

考虑区域创新中政府、企业及市场间的作用,理论分析中国政府科技支出对区域创新能力的影响及作用机理,采用30个省区（因数据缺失,未包含西藏地区及港澳台地区）2008—2020年面板数据以系统GMM模型和门槛效应模型检验其影响效应及非线性关系。研究表明：政府科技支出对区域创新能力有显著的激励作用和正向滞后效应;政府科技支出对区域创新能力的作用效力受到企业创新绩效、市场化程度的单门槛效应影响,存在效力发挥的关键期。研究有助于理清区域创新中政府与企业、市场的关系,对政府资金干预区域创新的形式作出思考,提升政府科技支出效率,增强区域创新能力。     

Measuring the Comparability of Company Accounts Conditionally: A Research Note

Comparability indices summarize the level of comparability between companies at a national and international level, an issue of importance to investors, regulators, and standard setters. Comparability indices can identify areas where comparability is low and where comparability is deteriorating. Furthermore, they can be used to quantify the extent to which initiatives such as International Financial Reporting Standards (IFRS) are successful in raising comparability between company accounts. Despite past literature emphasizing how factors other than country influence accounting methods used by companies, current comparability indices ignore these other factors. This paper introduces new national and international indices within the T index framework to fill this gap in the literature. Formula for the new national and international indices, and their standard errors, are provided. An example using European data is used to demonstrate the calculations and illustrate the importance of controlling for these firm specific factors.     

Margin regulation and volatility

An infinite-horizon asset-pricing model with heterogeneous agents and collateral constraints can explain why adjustments in stock market margins under US Regulation T had an economically insignificant impact on market volatility. In the model, raising the margin requirement for one asset class may barely affect its volatility if investors have access to another, unregulated class of collateralizable assets. Through spillovers, however, the volatility of the other asset class may substantially decrease. A very strong dampening effect on all assets׳ return volatilities can be achieved by a countercyclical regulation of all markets.     

从国际论文看各地优势领域与结构

以国际科技论文(SCI、EI、ISTP)作为科技产出指标，分析我国各省市区的科学研究绝对优势领域和相对优势领域；比较部分省市不同时期科研领域相对优势的变化，探讨各地学科结构变化，并对建设优势领域提出初步建议。     

Division and Combination of Labor in Aristotle's Biological Writings

In this paper, I explore the way in which Aristotle seems to appeal to certain principles of economics—most notably, the division and combination of labor—in describing and attempting to explain certain biological phenomena. I use examples recently employed in the bioeconomics literature and discuss how Aristotle uses similar examples in similar ways.
