本文从投资效率出发估计海南资本存量数据,并运用索洛余值法、隐含变量法和潜在产出法讨论了1978～2006年海南的全要素生产率变动。分析表明:海南全要素生产率增长与海南宏观经济波动趋势较一致,海南的经济增长主要依靠全要素生产率的贡献。 This paper estimates the capital stock of Hainan from the investment efficiency, and discusses the change of Hainan’s total factor productivity from 1978 to 2006 using the Solow residual method, the implicit variable method and the potential output method. The analysis shows that the growth of TFP in Hainan is consistent with that of Hainan’s macro economy. The economic growth of Hainan mainly depends on the contribution of total factor productivity.
