摘要
使用固定效应面板数据并运用随机前沿分析方法(SFA)测算中国中部6省81个地市2000-2012年全要素生产率。为了更好地刻画经济个体的异质性特征,在此模型中加入门限效应,使用贸易开放度作为门限变量。结果发现,随着门限变量值的提高,固定资本存量对经济增长的促进作用变得不再显著。该项发现的现实意义在于,并非外商直接投资占GDP比重越高越好,若要最大化发挥固定资本与劳动力对经济的促进作用,最佳的外商直接投资占GDP比重就应该在8.5%左右。
It is scientific and practical for using fixed effect panel data with Stochastic Frontier Analysis (SFA) to calculate 2000- 2012 TFP of 81 cities of China central six provinces. In order to better characterize the heterogeneity of economic entity, this paper adds the threshold effect to the involved model in the process of argumentation, uses trade openness as threshold variable. The result shows that, with the improvement of threshold variable, the promotion of fixed capital stock to econom- ic growth is no longer significant. The realistic significance is that the ratio of Foreign Direct Investment (FDI) to GDP is not the higher the better. To maximize the promotion of fixed capital and labor to the economy, the best ratio of FDI to GDP should be around 8.5%.
