沿边开放与区域经济增长——基于制度变迁的研究

主要关注沿边开放地区的制度变迁对经济增长的影响效应,基于2003—2018年我国8个沿边省份的73个地级城市面板数据,运用双向固定模型、分位数回归、门槛效应模型和中介效应模型进行科学严谨的研究,主要结论有:(1)沿边开放的制度变迁有利于促进区域经济增长,并且在一系列稳健性检验后,该结论仍然成立;(2)分位数回归发现,随着经济增长率分位数点的增加,沿边开放地区的制度变迁对经济增长的促进作用呈现出先变小、再变大的U型特征;(3)门槛效应发现,随着制度质量水平提升,沿边开放地区制度变迁对区域经济增长的作用效果呈现出边际递减的特征;(4)异质性发现,城镇化方面,高城镇化的沿边地区制度变迁促进经济增长的作用大于低城镇化地区。创新水平方面,在高创新水平地区,沿边开放的制度变迁显著促进区域经济增长,而低创新水平地区不显著;(5)中介效应发现,沿边开放地区的制度变迁主要通过外商直接投资和固定资产投资增加,进而促进区域经济增长,其中固定资产投资起到完全中介作用。结论为进一步深化改革开放、加快沿边开放地区发展和构建开放型经济新体制提供一定经验依据和政策支持。     

投资者信心和中国宏观经济波动——基于MIDAS混频模型

将投资者信心指数引入MIDAS混频模型之中,可以考察新冠疫情背景下投资者信心对于中国宏观经济波动的影响。基于投资者信心指数和“三驾马车”对我国季度GDP增长率进行预测,通过实证发现:引入投资者信心指数的MIDAS混频模型在预测精准度方面和基准模型进行比较,预测精准度高于未加入投资者信心的模型,均方根残差比值更小;在多元MIDAS混频模型之中,加入投资者信心指数的回归模型对我国GDP的实时预报和短期预测结果更加稳定,可为决策者提供更加精确的参考区间;宏观经济的波动对投资者信心指数变化反应,和投资、消费和进出口相比是最灵敏的。这为定量追踪宏观经济波动提供了一个新的视角。     

Financial manager's perception of rural household Economie Well-Being: Development and testing of a composite measure

An index of Perceived Economic Well-Being is constructed using factor analysis and tested for reliability and validity. The index is composed of (a) perceived income adequacy, and satisfaction with (b) current total household income, (c) amount of money your family is able to save, (d) amount of current debt, (e) level of consumption, (f) amount of household net worth, and (g) resources available to meet a financial emergency. The index is used in regression analysis. Results show that financial managers perceive economic well-being more favorably if they are more satisfied with resources and with the current level of living, view the present financial situation as better compared to 5 years ago, save on a regular basis for goal(s), and have a higher income. Financial managers who report more frequent financial problems, worry more about where money would come from to pay bills, and more frequently make only minimum payments on charge accounts perceive economic well-being less favorably.Preparation of this research was supported in part by the Illinois Agricultural Experiment Station. Data were collected in conjunction with the cooperative regional research project NC-182, Family Resource Utilization as a Factor in Determining Economic Well-Being of Rural Families. Cooperating states are Arizona, California, Illinois, Indiana, Iowa, Kansas, Michigan, and Minnesota.He received his Ph.D. from the University of Illinois in 1991 with Dr. Fitzsimmons as advisor. His current research interest is economic well-being.She received her Ph.D. from the University of Illinois; her current research interests include gender roles, family financial management, and economic well-being.     

Information and communications technologies, strategic asymmetry and national security

In the history of warfare, there are a number of examples of strategic uses of asymmetric technologies. Consistent with history and theory, individuals, organizations and nations have spotted opportunities to employ information and communications technologies to gain and exploit asymmetric advantages and to counter asymmetric weaknesses. This article discusses various asymmetries associated with institutions, nations and organizations that influence the ICT-national security nexus. Regulative, normative and cognitive institutions in a country provide various mechanisms that affect the nature of positive and negative asymmetries. Nations and organizations also differ in terms of their capability to assimilate ICT tools to gain positive asymmetries and deal with vulnerabilities of negative asymmetries. Integrative approaches that combine policy and technological measures at various levels are likely to make the world more secure.     

基于GRPLS 回归的 中国经济增长影响因素分析

构造一种新的方法———岭- 偏最小二乘回归方法(它既有效消除了因素变量之间的多 重共线性,又克服了传统方法的不足,且使模型更加稳健,具有更强的预测和分析能力) ;并运 用广义岭- 偏最小二乘回归方法分析了我国经济增长的影响因素,为我国制订持续、快速增长 的经济政策提供了有益的参考.     

中国内地和香港能否构成最优货币区研究--来自实证结果的分析

亚洲金融危机后 ,东亚和东南亚国家开始探讨亚洲货币合作问题 ,“亚元”也被提出并受到越来越多的关注。对于统一主权下的中国内地和香港来说 ,在这方面能否先行一步 ?尤其是随着两地经济一体化的发展 ,内地和香港会不会像欧盟那样在经济一体化条件成熟后采用单一货币呢 ?文章在最优货币区理论的基础上对内地和香港经济冲击的对称性进行研究 ,探讨人民币和港币是否有条件实现货币一体化。研究表明目前内地和香港经济冲击的对称性不够高 ,还没有满足组成最优货币区的条件 ,但是从内地和香港未来的发展方向来看 ,经济冲击的对称性将随着经济一体化程度的提高而提高 ,货币一体化的条件也将逐渐成熟。     

A Macro-Economic Framework for Evaluation of Cyber Security Risks Related to Protection of Intellectual Property

The article is based on the premise that, from a macro-economic viewpoint, cyber attacks with long-lasting effects are the most economically significant, and as a result require more attention than attacks with short-lasting effects that have historically been more represented in literature. In particular, the article deals with evaluation of cyber security risks related to one type of attack with long-lasting effects, namely, theft of intellectual property (IP) by foreign perpetrators. An International Consequence Analysis Framework is presented to determine (1) the potential macro-economic consequences of cyber attacks that result in stolen IP from companies in the United States, and (2) the likely sources of such attacks. The framework presented focuses on IP theft that enables foreign companies to make economic gains that would have otherwise benefited the U.S. economy. Initial results are presented.
