中国经济周期波动的阶段特征及驱动机制研究——基于时变概率马尔科夫区制转移(MS-TVTP)模型的实证分析

本文基于新凯恩斯附加预期的IS曲线,构造经济增长周期波动的一致合成指数代表综合产出缺口序列,选取状态空间模型估算预期变量,采用时变概率的马尔科夫区制转移(MS-TVTP)模型研究了中国经济增长周期波动的阶段运行特征与驱动机制.结论认为:产出缺口预期对经济周期波动的影响显著为正,实际利率变量对经济周期波动的影响显著为负,且两者的影响在不同区制具有明显的非对称特征.平滑概率和转换概率的估计结果显示,金融类和投资类先行指数是中国经济增长周期在各状态间转换的重要驱动因素.相对于促进经济回升,货币政策对经济的“降温”更有效.在经济回落时投资对经济增长周期波动的影响较为迅速,但由于投资周期和固定资本形成等原因,经济回升时投资发挥作用的滞后期明显加长.稳定预期并释放改革红利,实施宏观审慎管理平抑经济周期波动是保持中国经济稳定增长的重要途径.     

我国出口集装箱运价指数的持续期依赖特征研究

我国出口集装箱运价指数具有周期性波动特点。本文通过建立具有持续期依赖特征的马尔科夫区制转换(DDMS)模型,分析我国出口集装箱运价指数在周期性波动中的非对称性和持续期依赖特征。研究表明,我国出口集装箱运价指数在周期波动过程中具有非对称持续期依赖特征的两区制状态。     

生猪与猪肉间价格传导机制的区制转移与非对称性特征研究

基于具有马尔科夫区制转移的非对称误差修正模型,本文分析了我国生猪和猪肉价格间传导机制的区制状态、转移概率和非对称性特征。研究结果表明:生猪和猪肉价格水平值之间存在着长期协整关系,猪肉市场整合程度较高;它们的增长率序列之间存在着"对称性传导"和"非对称性传导"两区制的短期非线性动态调整关系;两区制间的转移概率具有非对称性,"非对称性传导"区制具有稳定性强、发生频率高和持续期长的特征;在"非对称性传导"区制中,猪肉价格对生猪价格上涨的调整幅度和速度均大于对生猪价格下降的调整幅度和速度。因此,降低生猪和猪肉价格间传导的非对称程度有利于提升储备猪肉政策的实施效果。     

我国生猪价格非线性波动规律的实证研究——基于Markov区制转移模型

本文应用三区制马尔可夫截距和方差转移的一阶自回归(MSIH(3)-AR(1))模型,对我国生猪价格的非线性波动规律进行了实证分析。实证结果表明,MSIH(3)-AR(1)模型很好拟合了我国生猪价格的变动过程,显著支持"价格下跌"、"价格平稳增长"和"价格快速上涨"三区制的划分,并且在不同区制上,生猪价格具有不同的波动水平、转移概率和持续期,因而价格调控政策应该依据区制特征来制定,最后给出了稳定生猪价格波动的政策意见。     

中美股票市场持续期依赖特点比较研究

采用持续期依赖马尔可夫转换模型,通过Gibbs抽样估计方法,对我国和美国股票市场的持续期依赖特点进行研究。研究表明我国股票市场在牛市和熊市中均具有较明显的持续期依赖特征,其中牛市的持续期依赖特点强于熊市。美国股市在熊市中有明显的持续期依赖特点,在牛市中几乎不存在这种特点。造成这种差异的原因,主要是由于我国股市投机程度较高。     

人民币外汇市场稳定性管理——基于内地与香港人民币汇率价差的视角

控制境内外人民币汇率价差在合理水平是保障人民币外汇市场稳定的重要环节和手段。本文以香港人民币市场为代表,运用时变转移概率Markov模型研究了2011年6月至2015年4月期间内地与香港人民币汇率价差的区制特征和区制转移的影响因素。实证结果表明:(1)汇差表现出显著的区制特征,在大部分时期内,汇差处于"正汇差-低波动"区制,这一差值可视为资本管制和内地与香港人民币市场结构差异对入境资本征收的"托宾税";在考察期的其他时段,汇差则处于"负汇差-高波动"区制;(2)汇差在区制间转移的概率受人民币汇率预期和境内外利差水平的影响,其中人民币升值预期和境内外利差扩大会促使汇差扩大,保持或转入"正汇差-低波动"区制的可能性提高。货币当局可以将影响人民币预期与调节利率水平作为管理境内外人民币汇差、稳定人民币币值和防范潜在金融风险的备选政策工具。

香港经济周期波动的经验分析

通过采用滤波技术得到香港经济周期波动的数据,在此基础上归纳出香港经济周期波动的特征,并分析了总需求变量与产出的周期波动关系.研究发现,香港产出波动周期长度为7.8年左右,且周期波动具有非对称性和弱可预见性.总需求波动中的投资、进出口和消费是顺产出波动的,基本具有一致的周期长度,是香港产出波动的主要原因,香港政府开支对产出波动没有影响.     

香港对外贸易与经济增长和产业结构升级——“一国两制”和改革开放的成功结合与实践

对香港1987～2007年时间序列数据单位根检验的基础上,验证对外贸易、经济增长与产业结构三者之间的Granger因果关系.研究发现,香港包括港产品出口、转口和进口在内的对外贸易与经济增长之间存在双向Granger因果关系;同时经济增长与产业结构之间也存在双向因果关系.通过对香港的研究进一步发现,香港地区对外贸易与经济增长,经济增长与产业结构之间能互为因果形成较好的经济运行状态,很大程度上得益于"一国两制"在香港的成功实践与内地改革开放的成功结合.
