宏观经济运行质量评价指标的选择方法

筛选指标的传统方法或者是定性分析或者是单一的定量分析。本文收集了37个反映宏观经济运行质量的指标信息,依据相关系数及其聚类分析,将相关程度不同的指标聚为不同的组或类,然后在相关系数高度相关的指标组进行因果关系分析,选取那些作为原因的变量或指标。利用相关时间序列建模方法中的向量自回归模型,及其脉冲响应函数和方差分解分析,进一步区分那些影响其他变量的重要变量。最后得到一组既能反映现象变化,又是主要或重要变量的14个指标。这一指标筛选方法不同于传统方法,它充分利用了指标之间的关联信息、因果信息和动态相依信息,具有综合性与实用性。     

大学生创业能力结构的理论分析与实证检验

大学生创业能力研究对建设创业型经济、完善高校教育体系和促进人的全面自由发展具有重要意义。通过理论与文献梳理,结合个案访谈结果,将大学生创业能力划分为机会发掘能力、组织管理能力、战略决策能力、资源整合能力、创新创造能力和挫折承受能力6个维度。根据因子内涵定义和相关学者研究成果,设计了大学生创业能力测量量表,并对江苏省高校进行了实证数据采集,验证了大学生创业能力结构的信度和效度。     

资本渐进开放下我国与国际利率的联动分析——基于中国和美国的比较

一般来说,利率在国家间的传导主要有两条渠道:国际贸易间的传导和资本自由流动下的利率平价机制。本文采取分阶段考察,通过建立计量经济学模型,利用单位根检验和协整分析加以验证,发现在资本项目部分开放后,中美利率开始具有联动效应,作用方式又具有自身的特点。目前资本项目开放度不够高是阻碍我国同世界利率联动的主要原因。     

The cointegrated vector autoregressive model with general deterministic terms

In the cointegrated vector autoregression (CVAR) literature, deterministic terms have until now been analyzed on a case-by-case, or as-needed basis. We give a comprehensive unified treatment of deterministic terms in the additive model $X_t=\gamma Z_t+Y_t$, where $Z_t$ belongs to a large class of deterministic regressors and $Y_t$ is a zero-mean CVAR. We suggest an extended model that can be estimated by reduced rank regression, and give a condition for when the additive and extended models are asymptotically equivalent, as well as an algorithm for deriving the additive model parameters from the extended model parameters. We derive asymptotic properties of the maximum likelihood estimators and discuss tests for rank and tests on the deterministic terms. In particular, we give conditions under which the estimators are asymptotically (mixed) Gaussian, such that associated tests are ${\chi }^2$-distributed.     

Market Integration of Fish in Europe

This paper examines market integration between fish species in Europe, taking international market integration into account. Based on Juselius (2006) , market integration is found both on the fresh and frozen markets. The Law of One Price is in force on the fresh market within the segments of flatfish and pelagic fish. Assuming transitivity, a loose form of market integration is identified between 13 fresh and seven frozen fish species, and the relative prices are found fairly stable. The policy implication is that catch limitation measures implemented through the Common Fisheries Policy have limited and conditional effects on prices, because of the large size of the market and varying market integration. Therefore, many fishermen are not ‘compensated’ by price increases as a result of catch limitation measures.     

甘肃省信贷投放与经济增长关系的实证分析

信贷作为一种重要的金融资源,对一国或一地区的经济发展起着举足轻重的作用.本文通过搜集1978-2007年甘肃省各年GDP及信贷投放额度数据,对甘肃省信贷投放与经济增长的关系进行实证分析,并得出以下结论:在样本区间内,甘肃省的信贷投放是经济增长的格兰杰Granger原因,即甘肃省信贷投放对经济增长具有一定的正效应作用,而甘肃省的经济增长对信贷市场的促进作用却不明显.     

瑞典碳税对产业结构水平影响的实证分析

为了降低二氧化碳的排放水平,实现可持续发展,一些国家以碳税作为发展低碳经济的重要手段。碳税是从多方面促进低碳经济的,对产业结构的升级和转型至关重要。在分析瑞典碳税政策、测算瑞典产业结构水平的基础上,本文对瑞典碳税与产业结构水平的关系进行实证分析。研究结果表明,瑞典碳税是提高瑞典产业结构水平的重要因素。据此,本文提出了关于我国开征碳税的建议。     

What drives stock market integration? An analysis using agribusiness stocks

This article explores the drivers of regional stock market integration with a focus on the agribusiness sector across relevant regional trade blocs around the world. We implement panel cointegration models to analyze the stock indices of agribusiness firms in the Southern Common Market (MERCOSUR), European Union (EU), Asia‐Pacific Economic Cooperation (APEC), and North American Free Trade Agreement (NAFTA). Based on the literature on market integration and stock return pricing, we identify nine possible determinants of stock market integration, which we separate into three categories: individual market performance, macroeconomic conditions, and agricultural trade. In our analysis, we account for agriculture‐specific factors to control for possible structural shifts in financial markets regimes by including the two main commodity price bubbles during last 20 years. Our results show that most of the variables included in our categories have been important factors in promoting regional stock market integration. Moreover, integration among regional stock markets was strengthened by the implementation of trade agreements. This effect is stronger in trade blocs with fewer members, such as NAFTA and MERCOSUR, compared with larger and more heterogeneous blocs, such as the EU and APEC.     

日本政府投资、民间投资和产业资本收益之间关系的实证分析

本文基于日本的统计数据,利用VAR模型和格兰杰因果关系检验方法,研究政府部门投资、民间部门投资和全产业总资本收益率之间的相互作用。VAR模型分析表明,政府投资对民间投资的影响比较大,两者对全产业总资本收益率的影响都很大且政府投资的影响远远大于民间投资,这些影响关系都较复杂。格兰杰因果关系检验表明,政府投资变化是民间投资变化的格兰杰原因,两者分别是全产业总资本收益率变化的格兰杰原因,而这些变量之间不存在相反方向的格兰杰因果关系。     

股市波动对股市募资的影响——基于VAR模型实证分析

本文选取1991年8月至2010年7月一级市场实际募集资金、上证指数及深成指的月度数据作为样本,运用向量自回归(VAR)模型、格兰杰因果关系检验、脉冲响应分析及方差分解方法分析股市波动与股市募资的关系,实证分析表明:股市波动是股市募资的原因,其中深成指对股市募资的影响较大;股市募资对股市波动短期有强劲的响应,在长期趋于稳定;股价指数和股市募资存在长期均衡关系。并且在定量分析和定性分析相结合的基础上给出相应的对策建议。
