我国生猪价格波动及对CPI影响的研究   总被引:1,自引:0,他引:1  
由于猪肉在构成我国CPI的所有规格品中所占权重最高,因此猪肉价格波动成为近年来物价变动的重要推手。本文分析了我国生猪价格波动的周期规律,探究了影响生猪价格波动的关键因素,并提出了平抑生猪价格波动幅度、营造宏观调控良好物价环境的相关建议。  相似文献

本文利用Eviews8.0计量分析软件,采用自回归分布滞后模型,初步考察2006~2016十年间的货币供应量M2与居民消费价格指数CPI之间的联系。结果表明,货币供应量变化(d M2)对物价水平(CPI)的影响具有明显的滞后性特点,其滞后期大约为1个月,并且其滞后期影响大约维持4个月左右,其影响力度呈现先递增后递减,滞后结构具有倒U型特征。同时还发现当期CPI还与滞后期CPI之间存在着线性关系。因此,我们应当继续加强货币供应量M2和CPI的调控机制,促进宏观经济的平稳增长。  相似文献

物价在宏观调控中具有重要地位,通过新技术、新手段不断优化CPI预测,对于有效开展宏观调控具有重要意义。本文创新性的将网络数据“清数-i CPI”和文本挖掘信息引入CPI预测,并通过混频数据构建了神经网络预测模型。首先将BERT模型应用于CPI预测关键词的扩展,其次引入“清数-i CPI”这一网络价格信息,最后将高频时间引入解释维度构建混频数据的人工神经网络模型。结果显示,利用文本挖掘和“清数-i CPI”构建的混频数据预测CPI结果稳定,文本挖掘信息对预测精度有明显提升,预测模型在拐点捕捉方面表现优秀,可提前一个月左右实现对CPI的预测。  相似文献

本文以A股市场的驱动方式逐渐由政策推动转变为业绩驱动为假设,定量分析了反映上市公司单位产品毛盈利的CPI、PPI差值与上证指数之间的关系。实证结果显示:CPI、PPI差值与上证指数之间关系稳定,并且其变动对上证指数的变动构成显著影响,可将此模型作为传统预测指数方法的拓展。  相似文献

本文假设央行会根据世界政治经济形势等外生因素对人民币货币篮子结构进行适时的调整,使用非方差约束的变参数状态空间模型,对人民币参照一篮子货币管理浮动汇率制度进行实证分析与预测检验,重点研究人民币货币篮子结构和趋势性升值速度及其变化规律等问题,对货币当局的外汇政策操作及其意图进行解读。研究发现,人民币区域化目标与欧债危机对货币篮子结构产生显著影响,汇改后人民币趋势性升值速度基本保持不变,政治事件是影响人民币短期偏离篮子汇率的重要原因。  相似文献

由于缺乏经验,我国商业银行固定利率住房抵押贷款定价存在不合理性,既影响了固定利率住房抵押贷款业务的健康发展,又导致了借贷双方风险与收益的不匹配。在市场利率服从几何布朗运动的基础上.本文从隐含期权视角出发构建固定利率住房抵押贷款单位风险收益最大化模型,并求出最优解,为商业银行固定利率住房抵押贷款定价提供理论和技术参考。  相似文献

基于马尔可夫链模型,对我国物价波动走势进行的实证分析表明:虽然消费者价格指数增长率大于6%时的概率很小,但是它一旦进入这个状态,就会有一个较长的持续期,在短期内很难降下来,而当消费者价格指数增长率小于-2%时,它的持续期较短.增长率大于零小于2%这一状态是消费者价格指数一个相对比较稳定的状态.对于商品零售价格而言,增长率大于-2%小于0这一状态是商品零售价格指数一个相对比较稳定的状态,同时在这状态它还有较长的持续期.  相似文献

本文通过研究国际商品价格对我国生产者价格指数(PPI)与消费者价格指数(CPI)的价格传递影响,得出结论国际商品价格对我国PPI具有正向传递作用,但PPI对CPI的价格传递过程失效;但是通过与美国进行对比分析发现,国际商品价格对美国PPI具有影响,PPI对CPI也具有影响。说明价格传递在中国的PPI向CPI的传递过程中失效,究其原因可能是因为下游企业具有完全竞争市场的特征,对商品定价能力较弱。  相似文献

The time-varying weights in the Chinese consumer price index (CPI) are estimated using a time-varying coefficient model, which is shown to be useful for testing the CPI’s “weighting biases” and adjustment problem. The empirical results show that China’s CPI has “weighting biases,” in which the time-varying intercept reveals negative adjustment of the CPI. This means that people pay less for food and more for medical care, education, and housing. By comparing the weights between urban CPI and rural CPI, the extended examination suggests a widening income gap between urban and rural households.  相似文献

In this paper, we propose a co-integration model with a logistic mixture auto-regressive equilibrium error (co-integrated LMAR), in which the equilibrium relationship among cumulative returns of different financial assets is modelled by a logistic mixture autoregressive time series model. The traditional autoregression (AR) based unit root test (ADF test), used in testing co-integration, cannot give a sound explanation when a time series passes the ADF test. However, its largest root in the AR polynomial is extremely close to, but less than, one, which is most likely the result of a mixture of random-walk and mean-reverting processes in the time series data. With this background, we put an LMAR model into the co-integration framework to identify baskets that have a large spread but are still well co-integrated. A sufficient condition for the stationarity of the LMAR model is given and proved using a Markovian approach. A two-step estimating procedure, combining least-squares estimation and the Expectation-Maximization (EM) algorithm, is given. The Bayesian information criterion (BIC) is used in model selection. The co-integrated LMAR model is applied to basket trading, which is a widely used tool for arbitrage. We use simulation to assess the model in basket trading strategies with the statistical arbitrage feature in equity markets. Data from several sectors of the Hong Kong Hang Seng Index are used in a simulation study on basket trading. Empirical results show that a portfolio using the co-integrated LMAR model has a higher return than portfolios selected by traditional methods. Although the volatility in the return increases, the Sharpe ratio also increases in most cases. This risk–return profile can be explained by the shorter converging period in the co-integrated LMAR model and the larger volatility in the ‘mean-reverting’ regime.  相似文献

固定资产投资项目绩效审计评价,不仅是评价审计质量的尺度,同时关系着国家固定资产投资监管的效果。本文在现有研究基础上进行了深入实地调研,并依据固定资产投资绩效审计评价指标选取的原则,构建了投资绩效审计评价指标初始变量,并经过问卷预测试和先导测试,确立了15个指标变量。以来自国家审计机关、会计师事务所、高校、科研机构的244份有效问卷为样本进行了交叉实证检验,对其中109份问卷进行探索性因子分析,将固定资产投资项目绩效审计评价指标归为四个维度,构建了评价模型,并对另外135份问卷做验证性因子,实证结果表明所设计的评价指标具有良好信度和效度,评价模型具有较好拟合优度,在某种程度上具有一定的使用价值和推广价值。  相似文献

In this paper, we derive a model of book-to-market value of equity based on the present value model and estimate it using panel data on individual stocks. We explicitly include in the model all the determinants of book-to-market except the firm-specific discount rate, which we capture using fixed individual effects in the panel data model. The model is particularly successful, explaining nearly 90% of the time series and cross-section variation in the ratio of book-to-market value of equity. Moreover, the estimated firm-specific fixed effects are more successful than the most recent book-to-market value of equity in forecasting subsequent returns. This is consistent with an efficient market in which book-to-market is a proxy for risk.  相似文献

Some recent empirical evidence suggests that stock prices are not properly modeled as the present discounted value of expected dividends. In this paper, we estimate a present value model of stock price that is capable of explaining the observed long-term trends in stock prices. The model recognizes that firm managers control cash dividend payments. The model estimates indicate that stock price movements may be explained by managerial behavior.  相似文献

This paper argues that earnings are determined as a response to wealth, measured by net value added, and as an adjustment to the previous year level of earnings. The model appears well specified when applied to a random sample of firms-years. The results highlight the importance of wealth generation and the previous level of earnings as determinants of earnings.  相似文献

We use the demise of silver-based standards in the 19th century to explore price dynamics when a commodity-based money ceases to function as a global unit of account. We develop a general equilibrium model of the global economy with gold and silver money. Calibration of the model shows that silver ceased functioning as a global price anchor in the mid-1890s—the price of silver is positively correlated with agricultural commodities through the mid-1890s, but not thereafter. In contrast to Fisher (1911) and Friedman (1990), both of whom predict greater price stability under bimetallism, our model suggests that a global bimetallic system, in which the gold price of silver fluctuates, has higher price volatility than a global monometallic system. We confirm this result using agricultural commodity price data for 1870–1913.  相似文献
