我国经济周期波动率的成分分解及稳定性研究

随着世界经济周期波动的减缓,我国经济波动也呈现出稳定性趋势.文章通过建立具有货币政策干预的产品市场均衡模型,对我国实际产出波动率进行了成分分解,并将实际产出波动的来源归结为需求冲击、供给冲击和货币冲击的作用.通过这些经济冲击方差序列的度量,又对实际产出波动率进行了冲击方差序列的回归检验,发现我国需求冲击和货币冲击强度的逐渐平稳是经济周期波动率降低的主要原因,而供给冲击对实际产出波动率没有产生显著影响.因此,我国宏观经济调控仍然需要坚持需求管理的政策导向,以保持经济持续稳定增长.

On Factor Decomposition and Stabilization of Business Cycle Volatility in China

The economic fluctuation in China has a stable trend with the smoothing world business cycle volatility. By constructing an equilibrium model in products markets under the intervention of monetary policies,the paper makes the factor decomposition of China's real output volatility and shows that the real output volatility is due to demand shock,supply shock and money shock. By measuring the variance sequences of these economic shocks,the paper makes a regression test of shock variance sequences and finds tha...
