摘要: 本文以经济增长理论为基础,对1953-2010年中国GDP数据和劳动投入、资本投入、人力资本等因素建立了半参数回归模型。然后,文章对模型了进行了统计诊断分析,计算了相关统计诊断量,利用统计诊断量得到了模型的异常点,基于此对中国GDP数据的准确性进行了讨论:中国GDP数据的异常点主要集中两个时间段1958-1961年和1991-1994年。文章最后对基于半参数回归模型统计诊断的统计数据准确性评估方法进行了评述。

Abstract: Based on the economic growth theory, this paper estimates a semi-parametric model with the data of China’s GDP from 1953 to 2010, labor, capital and human capital. Then, Statistical diagnostics analysis is carried out and diagnostic statistics are computed based on the estimated model. The accuracy of China’s GDP data is discussed based on outliers of the model:the outliers of China’s GDP data mainly lie within two time periods: 1958-1961 and 1991-1994. Finally, a review is presented on the method of assessing accuracy of statistical data based on the statistical diagnostic statistics of the semi-parametric regression models.
