摘要:

本文将国内资本市场摩擦和国际资本流动摩擦引入RBC模型,并采用贝叶斯方法校准模拟了中国经常项目的波动轨迹。研究结果表明:(1)国内资本市场摩擦和国际资本流动摩擦是形成中国经常项目波动的重要传导机制,两类资本市场摩擦机制的引入有助于准确拟合中国经常项目波动的波动性、协动性和持续性等各项特征;(2)贝叶斯估计得到的中国的资本调整成本和利率风险利差的参数值反映了中国资本配置效率和国际资本流动程度介于其他新兴市场经济体和发达经济体的水平之间;(3)中国经常项目波动主要由利率变动冲击和偏好冲击等两类结构性外生冲击通过国内资本市场摩擦机制和国际资本流动摩擦机制传导形成。

Abstract:

This paper studies Chinese current account dynamics in a real business cycle model extended with domestic capital market and international Financial Frictions. It estimates the model using Bayesian method. The results show that Chinese domestic capital market friction and international Financial Frictions are the important transmission mechanisms of Chinese current account dynamics, which will help to accurately fit the Volatility, CO movement, and persistence. Capital allocation efficiency in China and international capital flows degree are its ability to access international capital market are between the level of developed markets and that of other emerging markets. These capital market frictions amplify and propagate the interest rate risk premium shock and preference shock to drive Chinese current account dynamics.
