The Index of “Economic Independence”: A New Measure of an Economy’s Ability to Survive Unilaterally

The objective of this article is to fill an existing gap in the literature by constructing an index which attempts to assess the degree of a nation’s immunity to economic risk by quantifying its level of economic independence and its ability to survive unilaterally. To do so, and following the conventional methodology of indices, the article first identifies the dimensions underlying economic independence and then selects the various indicators that best reflect each dimension. It then normalizes each indicator by using its highest and lowest historic goalposts. Finally, it averages the composite index using specific weights assigned first to each indicator and second to each dimension. The economic independence index, which was constructed for 112 countries, provides a gauge to such countries on where they stand in terms of economic resilience and how much risk they face if they were to stand alone economically, or pursue policies that are undesirable from the perspective of more economically powerful countries. This index thus provides a tool for governments to measure the direction and magnitude of government action needed to improve their respective nations’ level of economic independence.     

An econometric analysis of global warming hiatus

There is an avid debate concerning the presence of a hiatus in global warming. Recognizing that this phenomenon has considerable economic implications, this study aims to make a threefold contribution to the climate econometrics literature. Firstly, it formulates a testable hypothesis; secondly, it proposes a systematic empirical procedure; thirdly, it performs the Bai–Perron test to detect the starting point of the global warming hiatus. The findings supported the existence of the global warming hiatus.     

A simple IID test for autoregressive conditional duration models

We propose using the rank-based variance ratio test as an easy-to-implement test for testing the independent and identically distributed assumption of autoregressive conditional duration (ACD) models. We apply the proposed test to duration data of five stocks and get the same conclusions as previous studies.     

出口退税与就业增进——基于我国数据的协整研究

在一个出口决策模型的基础之上,建立了一个出口退税的就业影响模型。并采用我国1985-2009年的数据,研究了出口退税政策对我国就业水平的影响,结果显示:我国的出口退税政策显著促进了国内就业的增长。进一步把出口退税分解为增值税退还与关税退还两部分,研究了不同类别出口退税对国内就业的影响,结果仍然稳定。结果同时表明:国内投资、FDI以及汇率贬值显著促进了国内就业的增长,而技术水平的提升则抑制了国内就业的增长,这一结果说明,我国的技术发展选择的仍然是劳动节约型而非资本节约型技术进步。     

外商直接投资对中国产业结构影响的实证研究

文章运用1983-2004年时间序列数据,应用Engle-Granger协整检验和Granger因果关系检验对外商直接投资对中国产业结构的影响进行了实证研究。研究结果显示:外商直接投资促进产业结构优化,但外商直接投资和产业结构变动之间不存在长期稳定的关系。在此基础上,文章建议积极引导外资为我国产业结构的优化升级做出更大贡献。     

外国直接投资对国有工业资本收益影响之探讨

本文分析了外国直接投资对我国国有工业资本收益的各种影响,并运用1985年至2004年的有关数据对两者之间的关系进行了协整分析,得出基本结论,从长期来看,外国直接投资额与国有工业企业利税总额之间存在着显著的负相关关系,这主要体现在外国直接投资对国有工业资本利润率的影响上。     

中国线材期货价格指数波动率预测能力分析

利用上海期货交易所线材期货15分钟高频价格数据构造已实现波动率估计序列,并以此作为参考标准,运用6种损失函数以及Diebold-Mariano检验法检验4类不同波动率模型对线材期货价格波动的样本外预测能力,显示,中国线材期货市场,基于高频数据的GJR(1,1)模型具有最为出色的波动率预测能力,而在某些损失函数标准下,HYGARCH(1,d,1)与GARCH(1,1)模型也体现出了较好的波动率预测能力。     

我国纺织服装业出口退税政策实证检验

文章以我国传统劳动密集型产业的代表-纺织服装业为研究对象,采用2004年1月至2010年8月的样本数据,对该产业出口退税率变动和月度贸易顺差增长率进行格兰杰因果检验,发现我国纺织服装业出口退税政策失效。基于实证结果进一步分析原因后提出了政策建议,认为转变出口退税政策的目标为结构调整、提高产业附加值,这不仅是保证今后我国出口退税政策有效实施的关键,而且是推动纺织服装产业升级的必要之举。     

海南省旅游收入与经济增长的关联度分析

根据海南省相关资料分析发现:旅游收入、入境旅游人次与GDP之间存在正向的长期均衡关系和双向的因果关系,旅游收入对经济增长的拉动作用低于入境旅游人次对经济增长的拉动作用。政府应充分发挥其市场导向作用,加大海陆空交通、港口等基础设施方面的建设,进一步加强对海南省物流、金融、电信等服务业的支持力度和规范管理,建立建全旅游市场经营的行业协会制度;企业应以社会和自然承载力为依据开发新的旅游产品,并融入文化要素,建立旅游产品品牌;同时,旅游企业要加强自身管理和市场竞争力的培育,吸纳并培养高层次的旅游管理人才。
