| 中文摘要: |
| 本文通过吸收资本存量（K）研究的已有成果，改进了K估算中经济折旧率为常数的假定，采用时变经济折旧率重新估算了1952～2010 年全国的资本存量。我们发现，以本文测算的时变经济折旧代替以往常用的固定折旧率，同时采用永续盘存法的原始公式代替常用的简化公式，有助于提高K估值的准确性。在此基础上，本文估算了宏观资本回报率，与多数文献所认为的宏观资本回报率具有长期下降趋势不同，我们发现1978~2007年中国宏观资本回报率呈长期上升趋势。 |
| 英文摘要: |
| This study aims to re-estimate capital stock (K) in china. We first estimate the actual economic depreciation rate, and find it is time-varying with an upward trend, rather than constant. We then estimate K by the principle of Perpetual Inventory Method (PIM) instead of its simplified version. As a result, we provide a new estimate of capital stock in China Mainland 1952-2007. Further verification of the estimation suggests that the employment of time-varying depreciation rates and the use of the principle of PIM have a great influence on the estimate of K. |
