The predictability of aggregate Japanese stock returns: Implications of dividend yield

This paper explores the implications of a dividend yield model for predicting aggregate Japanese stock returns using long time-series data from 1949 to 2009. In addition to one-period return tests, we conduct statistical tests based on dividend growth forecasts and long-horizon return forecasts implied by one-year regressions to provide significant evidence for the predictability of aggregate Japanese stock returns. Our findings therefore strengthen the international evidence for the role of dividend yield in predicting returns. However, we find that direct long-horizon regressions are not a powerful way of testing the null hypothesis of no return predictability. Moreover, we find that current cash flow is a more important driving force than future cash flow in the stock market fluctuations, although the dominant force is attributed to expected future returns.     

中日资源与环境技术预见比较研究

近年来,技术预见研究成为国际热点。当前,在我国开展技术预见研究,不仅是参与国际竞争和建设创新型国家的需要,而且是国家制定科技发展战略和科技政策的重要基础。对中国科学院知识创新工程重要方向项目"中国未来20年技术预见研究"中资源与环境技术领域的德尔菲调查进行了概要介绍,并与日本第7次技术预见相关内容(包括子领域划分、课题数量分布、重要程度综合得分前10位课题分布、技术预见活动问卷发放和回函情况等)进行了比较研究,并得出了一些初步结论。

基于群组决策特征根法的高技术企业知识产权开发评价指标识别

由于高技术企业知识产权开发评价影响因素多,涉及内容广,因此评价指标识别是高技术企业知识产权开发水平评价的关键环节。通过对当前高技术企业知识产权开发影响因素的分析,建立了高技术企业知识产权开发评价初选指标。运用群组决策特征根法对高技术企业知识产权开发评价初选指标的关键性和重要性进行识别,构建了高技术企业知识产权开发评价指标体系,为高技术企业知识产权开发水平的测度和评价提供了科学的方法和新的思路。     

基于SEM模型的制造业供应链稳定发展影响因素研究

中国制造业体量虽大,但产业供应链自主可控性和安全性尚未达到我国制造强国的发展要求。本文以制造业供应链为对象,通过系统地界定影响制造业供应链稳定发展的因素,并基于问卷调查法采集的样本数据,运用结构方程模型和AMOS软件,构建数字化转型程度、信息共享程度、供应链韧性程度和外部环境因素四大潜变量及其观测变量的指标假设模型,研究制造业供应链稳定发展的影响因素。研究发现,四大影响因素对制造业供应链稳定发展均有着正向的影响,而且根据路径的总影响效应可区分其影响力的大小。本文为制造业供应链稳定发展提供了微观证据,并期望为制造业供应链上各节点企业的发展提供一定启示。

风险分类对保险市场效率的影响分析

本文将社会福利作为衡量保险市场效率的标准,分析保险人的风险分类行为是否有助于信息不对称保险市场效率的提高.本文首先证明了信息不对称保险市场存在市场失灵,然后比较了实施风险分类前后社会福利的差异.结论表明:当保险市场处于R-S均衡时,准确性较高的分类能使社会福利得到改进,准确性不高的分类不能使社会福利得到改进;当保险市场...     

南通市资源节约型产业体系的构建与发展对策

我国资源支撑粗放型经济增长已经难以承受,建立节约型社会迫在眉睫。如何构建资源节约型的产业体系是建设节约型社会的重要内容。文章设计了资源节约型产业体系的分析框架,是一个具备资源利用现状分析层→资源利用效率分析层→应用层的三层分析流程。从重点行业和典型企业两个角度对南通市分别采用聚类分析和问卷调查的方法分析其产业的资源利用状况和效率,发现其产业结构陈旧、加工层次低,仍以高耗能、高污染排放的行业为主,但其资源减量和提高效益的空间较大。最后提出根据资源利用效率和污染排放确定的产业调整重点,把握调整力度,加快资源节约技术的推广和应用,建立资源型战略联盟。     

Does the Connectivity of the Belt and Road Initiative Contribute to the Economic Growth of the Belt and Road Countries?

ABSTRACT

Since the Belt and Road Initiative (BRI) has been implemented for five years, it is time to ask whether the BRI contributes to Belt and Road (BR) countries’ economic growth, and how are the five elements of connectivity implemented between China and its partner countries since the BRI was proposed. This study focuses on the development of the five elements of connectivity between China and the BR countries from 2008 to 2017 using a comprehensive connectivity index extracted from principle component analysis, and then investigating if the connectivity has contributed to the economic growth of the BR countries with quantitative analysis of the fixed effect econometrical model. It is found that Russia, South Korea, and Singapore presented the top three levels of connectivity with China with regard to the overall connectivity index, varying from 1.4 to 2.4. Madagascar and Panama have the lowest level of connectivity with China, with values of ?0.8 to ?1.1. The result of the fixed effect model shows that the connectivity of the BR countries with China contributes to their economic growth. This provides quantitative evidence that the connectivity between BR countries and China has a significant influence on the economic growth of those countries.
