经济增长的要素贡献测算新方法

New Analyzing Methodology of Productive Factors' Contribution

诺贝尔经济学奖得主索洛创造的“余值法”被中外经济学界广泛使用至今。该法测算的是生产要素对经济增长率的贡献 ;而本法测算的是对经济增长的贡献。索洛的测算式是导数公式 ,与年度数据不匹配 ,模型误差大 ;本法的测算式是增量式 ,与年度数据相匹配 ,模型误差小。索洛的“全要素生产率”概念的外延伸缩性大 ,已导致同一问题产生不同的测算结果 ;本法采用各生产要素单独贡献、共同贡献等概念 ,测算结果一致。

Nobel Economic Prize winner R.M.Solow created a “Residual Methodology” to calculate the production factor's contribution to economic growth rate which has been so far widely applied. Our methodology is to calculate the absolute contribution to economic growth. Solow's calculating formulae was of derivatives which did not match the annual data and incurred a model error; our calculating formulae is of increments which matches the annual data and has not any model error. Solow's extension of“Total factor productivity”is uncertain and has caused different results for same issue ; our methodology adopts independent and common contributions and has uniform results.
