利用我国1996-2011年29省面板数据,构建区域异质性随机前沿生产函数模型,并解构全要素生产率变化。结果发现:异质技术前沿下区域TFP增长率的变化趋势更契合地区经济发展差异;东部TFP增长呈稳中有降的“下台阶型”变化,中部呈稳中有升的“上台阶型”增长,西部则呈持续的“锯齿型”波动;相对于区域经济发展阶段,东西部技术选择存在欠适宜性。
利用我國1996-2011年29省麵闆數據,構建區域異質性隨機前沿生產函數模型,併解構全要素生產率變化。結果髮現:異質技術前沿下區域TFP增長率的變化趨勢更契閤地區經濟髮展差異;東部TFP增長呈穩中有降的“下檯階型”變化,中部呈穩中有升的“上檯階型”增長,西部則呈持續的“鋸齒型”波動;相對于區域經濟髮展階段,東西部技術選擇存在欠適宜性。

This paper constructs different production models using panel data of 29 provinces from 1996 to 2011,and then decomposes TFP growth. Result shows that the TFP trends from different frontier models are more in line with non-balanced regional economic development; the Eastern TFP has "down step"change,the Central,a steadily increasing "on stage";while the western is continued wave of "zigzag"; diseconomies of scale has been the biggest constraints in each TFP;compared to its economic development,the technology selection of Eastern and Western is less feasible.
