我国实际全要素生产率的估算:1980-2004年

Estimate of Actual Total Factor Productivity in China During 1980-2004

由于我国存在资本无效,简单地利用新古典经济增长模型进行全要素生产率估算就会得出错误结果。资本无效产生的根源是利率管制与福利制度改革导致的过度储蓄,无效资本掩盖了全要素生产率与劳动要素对经济增长的贡献,其参与收入分配造成收入分配差距扩大。在增长框架下通过固定资本产出份额对实际全要素生产率进行估算,通过估算,说明最近十几年来推动经济增长的动力主要是全要素生产率。

Due to the existence of invalid capital in China, the simple use of neoclassical economic growth model to estimate the total factor productivity will obtain inaccurate results. The cause of invalid capital is the over-deposit resulting from control of interest rate and reform of welfare system. Covering up the contribution to economic growth by total factor productivity and labor factors, invalid capital, involved in income distribution, leads to the widening of income gap. Under the growth frame we estimate the total factor productivity through the percentage of output by fixed assets. The estimate shows that in recent decade the major boost to economic growth is the lack of factor productivity.
