摘要
运用新凯恩斯动态随机一般均衡模型分析2004年至2014年中国主要宏观经济变量波动成因,重点考察了镶嵌于设备投资的投资专有技术冲击的作用。实证分析结果显示,投资专有技术冲击对总产出和设备投资存在显著正向且相对持续的影响,但短期内会对结构投资产生挤出效应;可以解释总产出与投资在短期与长期中40%~80%的波动;其解释力在包括全要素生产率冲击在内的五类外生冲击中居首。总体上看,促进设备更新并改善其生产效率的技术进步可以提高社会投资总水平,并带动经济中其他主要变量增长。
This paper examines the causes of the fluctuations of China's major c variables from 2004 to 2014 with New Keynesian dynamic stochastic general equilibrium (DSGE)model, focusing on the role of equipment investment specific technology(IST) shocks embedded in equipment investment. The empirical results show that IST shocks have signifi- cant positive and relative long-lasting effects on total output and equipment investment, but will have crowding-out effect on structural investment in the short term. Furthermore, the IST shocks accounts for the fluctuations in total output and investment in short and long run by 40 percent to 80 percent approximately, which is the first explanatory power among five exogenous shocks, including total factor productivity (TFP). Overall, the IST could increase the overall investment and promote the growth of other key variables in the economy.
